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 bodyB.improving athletes’ performance

C.detecting oxygenD.increasing level of oxygen

【3】What is Johnson’s attitude to the application of the findings to the athletes’ training?

A.NegativeB.Doubting

C.PositiveD.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

【题目】Northern California’s national parks appear pure and clean, almost untouched. But scientists are finding that there is more to this wild area than one can see. Even in the deep forests and on the mountain tops, animals may be poisoned by pesticides (杀虫剂) used in valley farms far below.

Researchers with the United States Geological Survey (美国地质勘探局) are working late into the night. They are searching for and catching frogs in the mountains of the Sierra Nevada. The Pacific chorus frog (拟蝗蛙) breeds in the high mountains just as the snow melts. The pools basically fill with meltwater, and as soon as the ponds melt the chorus frogs begin breeding there. Some Pacific chorus frogs in the mountains of California have tested positive for farming pesticides.

Gary Fellers is a researcher who once worked for the USGS. He and other team members are collecting the frogs to test them for agricultural poisons. No one farms in these forested national parks. However, winds carry chemicals from the Central Valley farming area into the mountains.

Kelly Smalling was the lead writer of the USGS study. “The decline of amphibians (两栖动物) has been documented for decades and decades. Some populations have gone extinct. And why these populations are declining is still a mystery.” Ms. Smalling says pesticides could be harming frogs and other amphibians.

The researchers tested pond water and soil from the bottom of the ponds. They were clean or almost free of pesticides. But tests on the bodies of the frogs showed the presence of 12 agricultural pesticides.

The concentration on the frog becomes greater than the concentration that is present on the water or some other part of the environment. Kelly Smalling says the next step is to find a way to deal with the pollution. “The first thing we need to do is understand how these chemicals that we’re finding harm the frogs. We have to understand the problem before we can fix it.”

【1】Animals in Northern California’s national parks ________.

A. are well protected

B. are killed by air pollution

C. are harmed by pesticides

D. will be sent to the farms in the valley

【2】According to the text, the Pacific chorus frogs ________.

A. breed when it snows

B. are only found in the ocean

C. are studied by the scientists

D. are free from the farming pesticides

【3】What will the researchers do next?

A. Keep the pond clean.

B. Deal with the pollution.

C. Find new homes for the frogs.

D. Search for and catch the frogs.

I passed all the other course that I took at my university, but I could never pass botany. This was why all botany students had to spend several hours a week in a lab look through a microscope at plant cells, but I could never see anything through a microscope. This was used to make my professor angry. “I can’t see everything，” I said. Then he began patient enough to explain how to see through it, but I still couldn’t make it. At last we tried it with every adjustment of the microscope known to men. With my pleasure, I saw something and drew it quickly on the paper. “What’s that？” my professor asked. “That’s what I saw.” I answered. “No, you don’t！” he shouted, and he bent over and looking into the microscope. “That’s your eyes! You’ve fixed the lens so that it reflects! You’ve drawn your eyes！”

【题目】阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

A wealthy man and his son liked to collect rare works of art. They had everything in their collection, from Picasso to Raphael. They would often sit together and admire these great works of art.

When the Vietnam conflict broke out, the son went to war. Unfortunately he died in battle while rescuing another soldier. The father was in deep sorrow for his only son.

About a month later, just before Christmas, there was a knock at the door. A young man stood at the door with a large package in his hands. He said, "Sir, you don't know me, I am the soldier for whom your son gave his life." "He saved many lives that day, and he was carrying me to safety when a bullet struck him in the heart and killed him instantly." "He often talked about you, and your love of art." The young man held out this package. "I know this isn't much." "I'm not a great artist, but I think your son would have wanted you to have this."

The father opened the package. It was a picture of his son, painted by the young man. He stared in surprise at the way the soldier captured the personality of his son in the painting. The father was so drawn to the eyes that his own eyes welled with tears. He thanked the young man and offered to pay for the painting. "Oh, no sir, I could never repay what your son did for me. It's a gift."

The father hung the picture on the hall. Every time visitors came to his home he took them to see the portrait of his son before he showed them any of the other great works he had collected.

The man died a few months later. There was to be a great auction(拍卖) of his art collection. Many influential people gathered, excited over seeing the great paintings and having the opportunity to purchase one for their collection.

【题目】For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but to_no_avail. It was only when I turned to meditation (沉思) for a solution that the answer came to me: turn to nature!

The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing I’m singing in the rain, a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain our own spirits, which only leads to depression and stress.

Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre.

If you feel a little low in spirits and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.

【1】The underlined part “to no avail” in Paragraph 1 probably means “________”．

A. unsuccessful B. unrelated

C. uninteresting D. unexpected

【2】In the author’s opinion, ________.

A. a bath can make people relaxed

B. depression is usually caused by hard work

C. walking in a busy city centre harms people’s health

D. it’s good for adults to wake up their inner children when they are in low spirits

【3】The last paragraph mainly serves as a(n) ________.

A. explanation B. suggestion

C. introduction D. reminder
