26、Every year, over 7.72 trillion kilograms of plastic is washed into the oceans. There are five huge areas in the world’s oceans that are a “soup” of floating rubbish. One of these areas, the Great Pacific Garbage Patch (GPGP), is three times as large as France.
Over a year ago, a group called Ocean Cleanup began using a huge floating screen to try to clean up plastic pollution in the ocean. After several failures, the group is now collecting plastic in the Great Pacific Garbage Patch. But the plastic is spreading out over a large area, so it's impossible to collect it piece by piece. So, the Ocean Cleanup had a plan. They got a long floating U-shaped tube with a screen hanging below it. As the tube and screen are pushed by the water and the winds, the U is meant to collect plastic rubbish, making it easy for a ship to collect and remove the plastic. The system uses the power of the wind and ocean, so it doesn’t need fuel.
The group began testing the first version, called “System 001”, last September. But it soon became clear that the screen was just moving with the plastic, not collecting it. Sometimes plastic would wash over the top of the tube. Even worse, System 001 got broken by surging seas and had to be towed to Hawaii for repairs.
But Mr. Slat, who got the idea for the Ocean Cleanup system, sees the project as an experiment, which means a failure is a chance to learn. The team collected and studied lots of information about what worked well and what didn’t. Then they changed the design. In June, an improved version, called “System001/B” was towed back to the GPGP.
The new version has a parachute (降落伞) attached to it. This makes the system move slightly slower than the plastic, allowing the plastic to be collected inside, as planned. But this success is still just the beginning of the work of the Ocean Cleanup. They want a better and larger system.
【1】What does the author want to show in Paragraph 1?
A．Humans should try to prevent plastic waste.
B．The GPGP is facing different kinds of pollution.
C．Plastic pollution in the oceans has become a serious problem.
D．A series of problems has been caused by plastic pollution.
【2】What was the group’s plan?
A．To make use of the water and the winds.
B．To create a ship to collect waste in the oceans.
C．To collect the floating plastic waste piece by piece.
D．To gather up the floating plastic waste in the oceans.
【3】What can we know about the “System001”?
A．It was a failure.
B．It was a great success.
C．It worked with a parachute.
D．It needed to be fueled regularly.
【4】What does the underlined word mean in Paragraph 3?

27、 A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.
【1】Which of the following statements is TRUE according to the passage?
A.Johnson believes that Oxygen sensors also exist in human skin.
B.People have to surf the Internet to read detailed findings.
C.It has been proved that these findings help treat lung diseases.
D.It has long been expected oxygen sensors exist in mice’s skin.
【2】One of the functions of the molecules mentioned above is _______.
A.carrying oxygen around the body B.improving athletes’ performance
C.detecting oxygen D.increasing level of oxygen
【3】What is Johnson’s attitude to the application of the findings to the athletes’ training?
A.Negative B.Doubting
C.Positive D.Hesitating
【4】The best title of the passage may be _______.
A.Great Findings Benefits Athletes A Lot
B.Frogs And Mice Are Distant Relatives
C.First Known Animal Breathes Through Skin
D.Humans Might Sense Oxygen Through Skin
28、 A new kind of rice, golden rice, may soon make its way into the world’s food supply by the year 2021, reports Science magazine.
Golden rice was actually first developed back in the 1990s by German scientists who were looking for creative ways to reduce rates of Vitamin A deficiency(维生素A缺乏症) in human body, which continues to be a major concern throughout the developing world. Beta-carotene(胡萝卜素), which exists in some plants, can change into vitamin A in our body.
In view of beta-carotene’s characteristics, German scientists tried and managed to make rice filled with additional beta-carotene, which has a strong red orange color. The beta-carotene that is added to this rice is actually what conduces to its special golden color.
To German scientists, developing this rice was meaningful. But as with all GM(转基因的) crops, some people warn that the golden rice may be unnecessary and even harmful, possibly having some environment consequences. Until now, those voices have prevented golden rice from being planted anywhere.
However, that’s about to change. Bangladesh now plans to become the first country to approve golden rice for planting. Recently, golden rice is receiving a series of tests before the final approval of Bangladesh. Tests conducted by the Bangladesh Rice Research Institute (BRRI) found no new farming challenges with golden rice and no big differences in quality between the crop and the traditional varieties, with the exception that golden rice is more nutritious. Some other organizations are still doing tests about the environmental influences of the crop. If those results are also good, then golden rice will have received all the approval it needs to move forward with planting.
As for the future market for the golden rice, the crop will need to gain the public’s trust. And it remains to be seen whether golden rice will offer a better nutritional and economical choice compared to other sources of vitamin A, such as other vegetables where it occurs naturally.
【1】What was German scientists’ main purpose of working on rice?
A.To raise its output. B.To make it look prettier.
C.To collect its beta-carotene. D.To improve its vitamin A content in our body.
【2】What does the underlined part “conduces to” in Paragraph 3 probably mean?
A.Causes. B.Changes. C.Removes. D.Lightens.
【3】What do BRRI’s tests show about golden rice?
A.It can hardly grow on the farmland of Bangladesh. B.It is nutritionally better than traditional rice.
C.It may do serious harm to the environment. D.It is no different from other rice in taste.
【4】How is golden rice’s future market in the author’s opinion?
A.Promising. B.Worrying. C.Uncertain. D.Hopeless.
29、When we think of 10-year-old girls, the first things that come to mind may be ballet, kitchen science experiments and crazy photo faces. There’s a special bond between young girls and their moms before life fills up with more demanding schoolwork, career choices and the stress of being a grown-up.
For Joyce Phillips, taking on adult emotions came sooner than expected. Her mother was diagnosed with breast cancer when Joyce was 10 years old. The thought of losing her mother at such a young age must have been troubling Joyce. But instead of waiting out the process on the sidelines, Joyce decided to join the fight against cancer so that other kids wouldn’t have to experience the pain she was going through.
Joyce loves to sew. She wanted to make something to sell and also advertise her need for help. While trying to piece together a solution, she hit upon the ubiquitous coffee cup. People everywhere seem to be on the go in the morning with their cup of take-out coffee. So Joyce designed a coffee cup sleeve and created her nonprofit Cozys for the Cure. It was a hit. Today, Joyce has raised over $120,000 to help fund breast cancer research. It all started with a desire to help. She lets us know each of us has the ability to make a difference, no matter how old or how young.
Joyce’s mother won her fight with cancer, but unfortunately, many more women and mothers will be affected. With kids like Joyce in their corner, perhaps the next best treatment will come a little sooner, save a few more lives, and means mothers and daughters will have a little more time to have fun together.
