Meet big brother Blue and his sisters Meadow and Little Willow，a family of three blind cats that just got adopted by the family Catherine Magno．
Their story starts just before the Christmas of 2014 when the kittens（小猫）were found in an abandoned house in Dubai．By then they had already lost their sight due to a cat flu that was left untreated by their previous（先前的） owner．After that they came to an animal home．At some point，brother Blue almost got adopted by the previous owner's neighbor，but the poor confused cat couldn't bear living without his sisters and cried all night while searching for them．Soon they were all united in the animal home until the important night of 19February 2015，when Catherine took them under her wing．
"I had zero experience having adopted my first ever rescue kitten just a couple of months ago，"Catherine said．"But their story touched my heart so much that I couldn't bear the thought of them being put in a cage for a very long time or even worse．"
Catherine was worried about the special needs of her new pet friends："My worry was that it's going to not only be challenging but also require a lot of adjustments on my part，"but apparently it wasn't that much different．"The only adjustment early on was keeping everything where it was but they are soon adaptive（适应的）．"And as she wonderfully put it："Blind pets see through their hearts．"

When we go on the Internet，we usually need a web address that ends with a suffix （后缀） such as．com，．net，．org，etc．Did you know that since 1984 only 22 suffixes have been used on the World Wide Web？Now more such suffixes are going to be available．Government bodies，cities，companies，or even a single person will be able to get any suffix they want as long as they'd like to pay $185，000 for it．
A generic top level domain （gTLD） is the suffix on the right of the domain name （域名）．Extensions now include．net，．org，．biz，．name，．tv，etc．，as well as country level domains such as．us for the US，．in for India，and so on．They were designed to show different kinds of website：．biz for business use，．org for non-profit （非营利性的） organizations，etc．
Think of the web address like the name of a person．In the case of www．baidu．com，the suffix"．com"is similar to the last name of a person-of which there are only 22 choices now．The prefix"baidu"is like the first name of a person-which can be taken according to availability．These changes will let you choose not only the first name but also a last name for your website．
As you can see，DNS （Domain Name System） is very important for directing the traffic for business over the Internet．Having the right domain name is important for building brands （品牌） and competing better in the marketplace．The new rules could mean more chances for e-business．
However，gTLDs can mean more costs for companies．Besides protecting their brand，companies may have to deal with cyber squatting（域名抢注）-this is when people have some domain names recorded formally with the purpose of selling them at a higher price．



Which of the following is TRUE of domain names？ ______

A. They are becoming less and less important．
B. Users won't need to pay for these names．
C. There will be more gTLDs for people to choose from．
D. Suffixes like．com and．net have a history of 50 years．

In the last paragraph，the author expresses his ______ ．

A. worry
B. doubt
C. excitement
D. politeness

The purpose of the text is to ______ ．

A. explain what a gTLD is
B. talk about new changes to gTLDs
C. introduce the history of the Internet
D. show how to deal with cyber squatting．

Just like the young character in Hannah Montana，who so often fights with her father over her desire to be more independent，British teenagers also have their troubles．
A recent survey among 2，000 British parents shows that girls and boys experience similar kinds of stress，with some slight differences．Girls want to grow up fast，demanding freedom．They feel pressure from their peers to be thin and sometimes dangerously experiment with alcohol．Girls over 14are more concerned with getting a boyfriend，make-up and going out with friends than with their schoolwork．They are more likely to complain about pocket money．Parents found they had their toughest time with boys over the age of 15．Their sons are battling bad skin and peer pressure，are unwilling to speak，and like girls over 14are little interested in their studies．Seven out of ten parents said their sons become frustrated when their need to be recognized as independent is overlooked．
Unsurprisingly，it isn't just British teenagers who have such problems．In a survey published in the US last month，two out of three high school students said their life was tough．Besides the worry over body images and ability to fit in socially，plenty of the teenagers feel great pressure to get good grades，with nearly 80% naming this as their top worry．The next biggest issue is pressure they face to get into a good college．According to the survey，66% reported saving their money to pay for all or part of college．"Today's American teens have witnessed what their families have gone through during recent economic challenges，and they are much more aware of the importance of planning ahead，"said Stuart Rubinstein，managing director of an NGO organization，which carried out the survey．

Many teenagers（青少年） feel that the most important people in their lives are their friends． They believe that their family members don't know them as well as their friends do． In large families，it is quite often for brothers and sisters to fight with each other and then they can only go to their friends for some ideas．
It is very important for teenagers to have one good friend or a group of friends． Even when they are not with their friends，they usually spend a lot of time talking among themselves on the phone． This communication is very important in children's growing up，because friends can discuss something．These things are difficult to tell their family members．

I am afraid of heights but two summers ago I climbed to a high place．Most of our high school had come along on a day trip to a beautiful beach village in Peru．After eating our lunches，many of us wanted to make the climb to an area around the village．
Do I turn back？"Yes!"Will I regret（后悔）it later？I really want to get to the top，but…At last，I decided at least to have a try．
My friend Tom was in front of me．Then，suddenly，he slipped（滑倒）and was about 10feet back!My heart was beating faster until he stopped himself．Knowing that my friend Seth would be right behind me，I began the climb．I was soon past the first challenge safely，but not feeling much better about the rest of the climb．Looking down，I saw rocks everywhere．My breathing sped up，and my heart beat even faster，growing loud in my ears．
My friends kept climbing．But they did not forget me．Someone was always behind me to help hold my feet when necessary，and someone else was always in front to offer a hand up．With friends helping me by words and actions，I slowly gainedground．
Then we came to the worst part．The climb looked very close to vertical（垂直的）．To me，the wise choice was to go back down．Melody encouraged me to go on and she made it safely first．I stopped，unsure of my footing．"You can do it，Jean!I'm right here，"Melody called．She waited patiently，not asking me to hurry．I took a few deep breaths and kept climbing．

It must have been a very clever human who looked at a sheep walking past and thought of the use its wool might have!
The oldest surviving textile（纺织品） made out of wool is around 3，500years old．Wool was probably the first fiber to be woven into textiles．Because when humans stopped hunting and started raising animals，it was their first step from a wild life to a civilized one．Sheep became a convenience store for the new lifestyle of our ancestor during the Stone Age，a walking food supply that required little care．Sheep provided all---meat and milk for food，skin and bones for clothing，shelters and tools．
Some sheep were suitable to roast while others were to produce wool，as sheep fit for eating do not necessarily have high-quality wool．Early wild species of sheep had long outer hair protecting their short wool undercoats．It was this underlayer that was highly suitable for textile use，so they were selectively bred into modern sheep．
Great empires were built on the backs of sheep and their wool．Around 1800BC，the civilization of Babylonia was famous for its wool．After the Romans conquered Spain，they developed a new breed that would come to be known as Spanish Merino，with the whitest，finest wool ever known．Today，the Merino is the most highly regarded breed in the world．
The Chinese held onto the secret of silk for thousands of years before Europeans even got an idea about how to put two threads together．With wool， they seem to have got their revenge．
