Though plastic shopping bags are cheap and useful, they cause widespread pollution. Now, we may have an unlikely helper to help clean up our garbage — a small wax worm.

The worm’s hidden skills were discovered by accident. About two years ago, Federica Bertocchini, a developmental biologist at the Spanish National Research Council and an amateur beekeeper, was cleaning out bees’ nest that had been filled with worms. She removed the worms and put them in a plastic bag while doing the cleaning. After finishing, she went back to the room where she had left the worms, and found they had escaped from the bag. When she checked, she saw that the bag was full of holes.

Realizing she may have made an important discovery, Bertocchini teamed up with other researchers to conduct further research. They began by placing 100 worms on some plastic bags and discovered that over a 24-hour period, the worms managed to chew through 92 milligrams of plastic. The researchers make an appropriate judgment that at this rate, the group of worms could　 degrade (降解) an average-sized 5.5-gram plastic bag within a month. To rule out the possibility that chewing was causing the degradation, the researchers spread the soft wet substance inside the body of some recently dead worms on a sheet of plastic. Sure enough, even the liquid was able to eat through the material, confirming that the worms have plastic-digesting enzymes (酶).

While the news is certainly encouraging, not everyone is convinced. The Michigan State University’s Ramani Narayan believes the tiny pieces of microplastics released by the plastic-eating worms would pick up harmful substances and transport them up the food chain, causing, even more, harm to the environment and human health. Susan Selke, director of Michigan State University School of Packaging, is concerned that the worms will not be able to survive in an oxygen-free landfills where large amounts of waste material are buried under the earth.

However, Bertocchini is not planning to transport worm armies to landfills. Instead, the researcher wants to identify the enzyme that helps degrade the plastic. The researcher says, maybe we can find the molecule (分子) and produce it on an industrial level, rather than using a million worms in a plastic bag.

1.What did the experiment of using dead worms find out?

A.Worms’ chewing may cause the degradation.

B.A plastic-eating chemical exists in wax worms.

C.Dead worms are effective in dealing with plastic.

D.It takes a long time for worms to degrade plastic.

2.What is Ramani Naravan's attitude to Bertocchini's finding?

A.Objective B.Convinced C.Questioning. D.Optimistic.

3.What might Bertocchini focus her later research on?

A.The structure of plastic-degrading enzymes.

B.The use of other worms in disposing plastic.

C.Wax worms’ adaptability to the landfill environment.

D.The chance of producing wax worms on a large scale.

4.What is the best title for the text?

A.Can wax worms save the environment?

B.Wax worms have an appetite for plastic.

C.Why do wax worms have plastic-eating skills?

D.Hungry worms join the fight against plastic pollution

It is rightly said one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend’s secrets to yourself and not telling the world is what makes the bond grow strong and last forever. You need to develop trust and mutual (互相的) understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend’s mind.

There is a certain time in life especially from the teenage years when one starts having a personal periphery (界限) in life and parents are excluded (排斥) from it. It is because there are certain things that they can’t understand and we can’t discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one’s feelings and best kept secrets.

It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range (变化) from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.

Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.

1.What is an advantage of sharing secrets with a friend?

A.It helps a lot in your study.

B.It leads you to a carefree life.

C.It makes you popular with other people.

D.It contributes to a long-term mutual belief.

A quarrel at home may result in your falling ill. Don’t laugh, it’s true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.

Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.

“We don’t get sick or stay well by ourselves,” says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research. The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA.

Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too. Ferrer’s research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick.

We may never fully understand all the effects that families have on our health. But just as individual (个别的) problems can have effects on others, a small improvement can have big benefits, Ferrer said.

1. Which of the following can best explain why Wang Xiaoyu fainted in class?

A. Because her classmates often quarreled in class.

B. Because her parents used to quarrel.

C. Because of her depression caused by bad family relations.

D. Because her classmates shouted loudly at her.

2. According to Dr Ferrer, which of the following statements is TRUE?

A. We get sick or stay well by ourselves.

B. Only the genes we get from our family have a big effect on our health.

C. Our health has nothing to do with diet, lifestyle and environment.

D. Teenagers who are ignored at home get sick more easily than those who are not.

3. The underlined word “coma” in Paragraph2 probably means ________.

A. surprise                  B. faint         C. tiredness           D. sadness

4.The best title for this passage is ________.

A. Family relations.                              B. The reasons why we get sick.

C. Family---- another cause to health        D. A research about health.

Instagram is a fast，beautiful and fun way to share your life with friends and family．Take a picture or video，choose a filter to transform its look and feel．and then post to Instagram—it's that easy．You can even share to Facebook．Twitter and more．It’s a new way to see the world．So many photos of food are contained on Instagram—now a pop-up diner in London is taking advantage of this new trend by letting people settle the bill for their meals simply by uploading photos of their dishes to social networks．

I always thought people’s taking pictures of their food was kind of silly, but at this new pop-up restaurant in the UK，I’d probably do it too．“The Picture House”is the world’s first pay-by-photo restaurant—you order， click a photo of the food，share on Instagram and eat for free!

The restaurant belongs to frozen food giant(巨人)Birds Eye，who came up with the idea to cash in on people’s addiction with photographing food and sharing the pictures online. They conducted a survey and found out that more than half of the British population regularly took pictures of their meals．So they realized it was a better way to advertise their new dining range．

The pop-up diner was open in Soho，London for three days in May，and is now moving to other major UK cities．They serve two-course meals that customers don’t have to pay for, if they photo and instagram it．

The restaurant is a part of Birds Eye’s“Food for Life”campaign，a new marketing project that aims at changing the way people look at frozen food．“Taking photos of food enables people to show off and to share their mealtime moments—from the everyday to the special，”said marketing director Margaret Jobling．

The reaction to The Picture House has been great so far And the pay-by-picture concept has proven to be an effective way．Alternative payment methods are actually gaining popularity among a lot of businesses．Last year in a cafe in Germany customers pay by how much time they spend there，not by what they eat．

1.Instagram probably is______．

A．a restaurant free of chmge

B．a campaign of“Food for Life’’

C．a program used to share photos

D．a new marketing project

2.What’s the author’s attitude to this new trend?

A．Confused　　 B．Unconcerned　　 C．Opposed　　 D．Interested

3.“The Picture House”encourages sharing photos of its food to_____．

B．attract more customers

C．create a new social media trend

D．reward the regular customers

4.Which of the following can serve as the best title for the passage?

A．Pay by Picture　 　　 B．The Pop-up Diner
