It is a sad truth that any health crisis （危机） will lead to a large outbreak of misinformation.
  In the 80s, 90s, and 2000s we saw the spread of dangerous lies about AIDS - from the belief that the HIV virus was created by a government laboratory to the idea that it could be treated with goat's milk. These claims increased risky behaviour and worsened the crisis.
  Now, we are surrounded with unreal news - this time around Covid-19 （新冠肺炎）．The Economist in March 2020 found 13% of Americans believed Covid-19 was a trick while 49% believed the virus might be man-made. While you might hope that greater brainpower or education would help us to tell facts from lies, it is easy to find examples of many educated people falling for false information. Kelly Brogan, who has a degree from the Massachusetts Institute of Technology, has refused clear evidence of the virus's danger in countries like China and Italy and even questioned the health officials.
  Part of the problem arises from the nature of the messages themselves. As BBC Future has described in the past, suppliers of false news can make their message feel "truthy" through a few simple tricks, which discourages us from using our critical thinking skills.
  For example, a simple image alongside a statement increases our trust in its accuracy （准确）---even if it is only partly related to the statement. Moreover, even the simple repetition of a statement can increase the "truthiness" by increasing feelings of familiarity.
  These tricks have long been known by peddlers （传播者） of misinformation, but today's social media make the spread more easily. Recent evidence shows that many people share information on the Internet without even thinking about its truthfulness and ignoring the obvious question： is it true？

A. By giving examples.
B. By making comparisons.
C. By doing scientific research.
D. By explaining statistical data.

A. it's unfamiliar to them
B. it's attached with clear evidences

B. Fake news peddlers have long tricked people into ignoring truth.
C. Some tricks prevent people from applying critical thinking skills.
D. It's today's social media that speed up the spread of misinformation.

Let's get through the work quickly._______seems to be little time left now.（　　）

Picking pineapples can be hard, heavy work often with little reward. The price paid for each individual fruit is a small part of a penny.
  The leaves from pineapple plants are usually thrown away. A use for them has now been found, turning the leaves into fabric, which provides some extra income for workers.
  "I think everybody is quite surprised that the fabric is made of pineapple, because it doesn't smell like pineapple, it's not spiky, it's got a nice texture（质地） to it. So it's quite an unusual thing to be working with." said Ben Patton, designer for Material Products.
  To make the fabric， fibers are extracted（提取） from the leaves. These get sent from the Philippines to Spain.
  Once there, machinists complete the process of turning them into a material which has been named 'Pinatex'．
  An online shop based in Cambridge has begun using Pinatex to create handbags, satchels and purses.
  And these are the finished bags. If you want one, they'll charge you around 137 pounds. The texture is slightly crinkled - not too different to some leathers.
  As manufacturers become more confident using the material, it's hoped that more items will be made out of it in the future, making use of pineapple leaves that were otherwise destined to be wasted.



What is the function of the first paragraph？ ______

A. Giving the main idea.
B. Bringing in the topic.
C. Raising the problem.
D. Introducing the background.

Why are Ben Patton's words quoted here？ ______

A. To show that the pineapple is a useful fruit.
B. To show that pineapple leaves are comfortable to feel.
C. To show that the new material is surprisingly good.
D. To show that the product is profitable.

What does the underlined word "fabric" in the fourth paragraph mean？ ______

A. Cloth.
B. Leather.
C. Bag.
D. Money.

What is the writer's attitude towards this use of pineapple leaves？ ______

A. Favorable.
