There is no better way to enjoy Scottish traditions than going fishing and tasting a little whisky(威士忌) at a quiet place like the Inverlochy Castle. When Queen Victoria visited there in 1873 she wrote in her diary, “I never saw a lovelier spot,” And she didn't even go fishing.
Scotland is not easily defined. In certain moments, this quiet land of lakes and grass mountains changes before your very eyes. When evening gently sweeps the hillside into orange, the rivers, teeming with fish, can turn into streams of gold. As you settle down with just a people and a basket on the bank of River Orchy, near the Inverlochy Castle, any frustration will float away as gently as the circling water. It's just you and purple, pink, white flowers, a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime's fun. For many, fishing is more than a sport; it is an art.
Scotland offers interesting place where you can rest after a long day's fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland's mountains. Ben Nevis is the highest of mountains, and reaching its 1342-metre top is a challenge. But it's not just what goes up that matters; what comes down is unique. More than 900 metres high, on the mountain's north face, lies an all-important source of pure water. Its name comes from the Gaelic language "usqueb" or "water of life"; and it is the single most important ingredient(原料) in Scotland's best known whisky.
（1）The story of Queen Victoria is to show that       .
A.the queen is rich in tour experience
B.the Castle is a good place to go in Scotland
C.tasting whisky is better than going fishing
D.1873 is a special year for the queen
（2）How is Paragraph 2 mainly developed?
A.By giving descriptions.
B.By following time order.
C.By analyzing causes.
D.By making comparisons.
（3）What is Ben Nevis special for?
A.The Inverlochy Castle Hotel.
B.The beauty of its surroundings.
C.The water from the mountain.
D.The challenge up to its top.

Energy goes from one plant or animal to another. A food chain shows how this energy moves. Each time an animal gets eaten, its energy is passed onto the animal that eats it. The food chain is very important because it keeps the balance of nature. If one part of the food chain disappears, it can affect all the other plants and animals. Any threat to the food chain is a threat to the environment's biodiversit(生物多样性). The food chain helps keep animal populations in balance. However, if something happens to increase or decrease one of the links in the food chain, that balance is broken. If one animal becomes endangered, it puts all the animals above it at risk.
Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment.
A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鳍). Now, not enough sharks are around to eat the cownose(牛鼻) ray. The ray's population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商业的) fishing.
Many of us disturb the natural environment in our own backyards. It's up to us to take care of the environment and try not to disrupt the natural food chain. If we don't act responsibly, animals will start disappearing.
（1）What can we learn from Paragraph 1?
A.The food chain is not easy to be broken.
B.The energy of an animal usually disappears when it dies.
C.Increasing the links will not break the balance of nature.
D.Breaking the food chain is bad for the biodiversity of the environment.
（2）The study mentioned in Paragraph 3 proves that      .
A.human activities can be a big threat to the food chain
B.we are all responsible for the breaking of the food chain
C.natural disasters are hard to break the food chain
D.hunting large sharks for meat is beneficial
（3）We can infer that the writer wrote this passage mainly to      .
A.explain what the food chain is
B.tell us something interesting about Nature
C.suggest that we stop eating meat to save animals
D.suggest that we not disrupt the natural food chain

Bees and other pollinators（传粉者） use smells to track down fresh flowers. Air pollutants can weaken those scents（气味）. Scientists had worried this might make it harder for some pollinators to find a meal.
Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat（栖息地）can be one factor. Diseases and exposure to poisonous chemicals also count.
Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.
Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive（蜂巢）or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.
In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air. Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.
Worse still, air pollution might do more than just weaken scent plumes（气味烟云）．Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.
That's certainly Fuentes' concern. So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.
（1）What does the underlined word "this" in Paragraph 2 refer to?
A.Weakening scents.
B.Pollinating plants.
C.Finding a meal.
D.Smelling flowers.
（2）How would bees be affected by their difficulty in finding meals?
A.They may get lost.
B.They may get burnt out.
C.They may die from hunger.
D.They may be killed by enemies.
（3）Why do bees spend longer time in search of flowers in polluted air?
A.They lose their ability to smell flowers.
B.Scented plumes travel in a new direction.
C.Flower scents spend more time reaching them.
D.Air pollution makes flowers emit fewer scents.
（4）What is Jose Fuentes' attitude towards insects' ability to adjust to new conditions?
A.Positive.
B.Worried.
C.Unclear.
D.Disappointed.

A Hobby is a regular activity that is done for enjoyment, typically during one's leisure（闲暇的） time. By continually taking part in a particular hobby, one can acquire practical skill and knowledge in that area. Is travel a good hobby? Travel, in the youngest sort, is a part of education and, in the elder, a part of experience. Some may think otherwise. To them, visiting churches, castles, libraries, etc. is an absolute wastage of time. They may further say that one can read the account of these or see the films of the important places of the world. They forget that touch of actuality gives a different type of sensation and satisfaction.
Travelling may be an expensive hobby but it makes up for the financial loss. If a traveller has interest in life and its manifestations（表现）, one can find much to keep oneself absorbed and happy. A student of any stream can definitely find something of his own interest and studies. One can definitely find everything that satisfies his cravings for knowledge and feelings.
As a hobby, travelling keeps us busy during leisure time; it is the best method to make use of time. Till a person breaks from dull routine, physically and mentally, one cannot find satisfaction. Travelling helps us to achieve this break. At a new place, one is curious to know and eager to gather all the unknown information about the place which he has neither read nor heard before and he gets thrills and surprises which keep the interest and enthusiasm alive and encourage us to keep our journey on.
While travelling, one comes across a number of people from varied backgrounds and places. By interacting with them, he comes to know about their traditions also. In case one has psychological bent of mind, one increases one's experience and power to understand others. Understanding human nature is, perhaps, the best part of education. Travelling satisfies all demands of a good hobby-it is absorbing education and refreshment to the mind, body and soul.
（1）What is the first paragraph mainly about?
A.Different views on travel.
B.The drawbacks of travel.
C.The importance of touching nature.
D.Differences between a hobby and travel.
（2）Which of the following can replace the underlined word “cravings” in the second paragraph?
A.changes.
B.researches.
C.desires.
D.problems.
（3）What can a person do to benefit himself both in his mind and body?
A.Travel about at his rush hours.
B.Take a break from daily routine by travelling.
C.Stay curious to know things around every day.
D.Interact with people from diverse cultures.
（4）What is the best title for the text?
A.Curiosity Killed the Cat

For many of us, talking about money is embarrassing, especially revealing our income and spending habits in public. So it's no wonder that seeking investment advice from computer program is so popular.
Consultancy firm Accenture found that 68% of global consumers would be happy to use robot-advice to plan for retirement, feeling it would be faster, cheaper, and fairer than human advice. “Many of our customers say they feel awkward in face-to-face meetings, preferring an online experience where they don't feel nervous,” says Lynn Smith, a director of robot-advice firm Wealth Wizards. So how does robot-advice work and is it really any better than traditional financial advice?
Robot-adviser firms use algorithms (算法) to analyse your financial situation and goals and then work out an investment plan to suit you. Basically, you answer lots of questions online about your income, expenses, family situation, attitude to risk and so on, and then the algorithm allocates (分配) your savings to a series of investments, from index funds that aim to imitate a particular stock market index or sector, to fixed-income bonds.
Robot-advice is certainly growing in popularity. But are we really happy to give up the human adviser completely? “No” is the short answer. Accenture finds that a significant proportion of us still want human interaction, particularly when our finances are complex. “When a customer needs advice surpassing a number of different regulatory regimes, human advice will be required, says John Perks, managing director of life and pensions at UK insurer LV, which launched its Retirement Wizard robot-advice service two years ago.
The truth is that only about a quarter of funds managed by clever humans overcome the market as a whole, so when you take into account the much higher management fees you pay for that kind of service, the performance difference is likely to be marginal (微不足道的) for most of us.
The robots may be coming, but in this case at least, they seem to be on the side of the small investor trying to save for a comfortable retirement.
（1）What do we know about the robot-advice from the second paragraph?
A.It's suitable for all.
B.It's complex but fair.
C.It's expensive but accurate.
D.It's beneficial and relaxing.
（2）If you want to use robot-advice, you should first ________.
A.consult human advice
B.work out an investment plan
C.answer lots of questions online
D.analyse your financial situation
（3）What does the underlined phrase “that kind of service” in Paragraph 5 refer to?
A.The allocation of retirement.
B.The performance difference.
C.Human fund management.
D.The robot-advice service.
（4）Why do we still need the human adviser according to the text?
A.Because some finances are complex.
B.Because some clients face retirement.
C.Because human interaction is necessary.
D.Because the human adviser offers better service.

Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
（1）Which of the following statements is true?
A.Nuclear radiation is just like common radio waves.
B.Nuclear radiation can cause cancer to human beings.
C.Nuclear radiation can be detected by human senses.
D.Nuclear radiation can be safe to human beings if its level is low.
（2）How can nuclear radiation kill an animal?
A.By damaging its heart.
B.By killing a few cells.
C.By hitting any place in its body.
D.By killing many cells in important organs.
（3）If a human being is hit by nuclear radiation, he may __________.
A.die of cancer after many years
B.die immediately
C.have a child who may be born weak
D.all of the above

2017 was an influential year for artificial intelligence (人工智能), not just in terms of the advancement of the technology itself, but also for the development of our understanding of AI's impact on our society.

When we talk about AI, often we focus on the belief that it is going to take away certain types of jobs. However, we often ignore the fact that this technology will also slowly spread into most of our lives.
Thanks to the development of AI, we are on the highway of IA, (human) intelligence augmentation (增强). Despite the great steps we've made in AI development and will continue to make in 2018, we are still years away from AI fully replacing human jobs. However, we are much closer to seeing the impact of AI spread into almost every job and the growth in human intelligence.
Take a doctor for example: AI will soon be able to detect and diagnose common diseases more quickly and accurately than humans. Now, doctors can spend more of their time explaining the possible diagnoses, communicating with patients and developing unique, reliable treatment plans that are most effective for each specific patient.
However, AI is so powerful and its adoption will only accelerate as it begins to help our work and allow us to focus on the parts of our job that are most important. But part of why AI is so attractive is also why it's so dangerous. That is, that same power allows AI that are making incorrect decisions to do so with greater speed and impact than humans have ever had.
This is why, as AI becomes more useful in 2018, it will also become more closely examined. 2018 will be the year when companies purchasing AI products don't just ask about the power of AI—they will make sure that it is tested carefully in advance, minimizing their potential unexpected impact.
（1）What does the author suggest in the first two paragraphs?
A.Many jobs should be replaced by AI in the future.
B.People should think more about the impact of AI.
C.AI is too abstract for ordinary people to understand.
D.People care little about the development of AI.
（2）The author takes the example of “the doctor” to explain that       .
A.AI always makes right decisions
B.doctors will lose their jobs very soon
C.human intelligence grows with AI
D.humans are no better than AI in medicine
（3）What will be the focus about AI in 2018 according to the author's prediction?
A.The safety of AI.
B.The possibility of replacing humans.
C.Cost reduction.
D.Power augmentation.
（4）What is the author's attitude towards AI?
A.Indifferent.
B.Negative.
C.Doubtful.
D.Objective.
