Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
Sounds is measured in units called decibels (分贝). At a level of 140 decibels people feel pain in their ears.
Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that has already faced enough stress.
1.The sense of sound _________.
A. makes us feel excited
B. helps us hear more clearly
C. is something harmful to us
D. helps to know what is happening around us
2.When sound is turned into noise, ______________.
A. people grow worse and worse
B. it makes us forget all the past
C. people don’t know what to do with everyday life
D. it will be a kind of pollution to people
3.Why does the passage say peace and quiet are becoming harder to find?
A. Because the world is making more and more noise.
B. Because wars and battles happen here and there in the world.
C. Because all the sounds are becoming over 140 decibels.
D. Because some machines can make noise.
4.Doctors say we can hear ourselves think __________.
A. if we don’t like to hear noise
B. if we have no aches or pains in our bodies
C. if there isn’t too much noise
D. if we can’t be careful of noise

Marie Curie was a Polish-born physicist and chemist and one of the most famous scientists of her time. Together with her husband Pierre, she won the Nobel Prize in 1903, and another one in 1911.
Marie Sklodowska was born in Warsaw on 7 November 1867, the daughter of a teacher. In 1891, she went to Paris to study physics and maths at the Sorbonne where she met Pierre Curie, professor of the School of Physics. They married in 1895.
The Curies worked together studying radioactivity(放射性), building on the work of the German physicist Roentgen and the French physicist Becquerel. In July 1898, the Curies announced the discovery of polonium(钋). At the end of the year, they announced the discovery of another, radium(镭). The Curies, along with Becquerel, won the Nobel Prize for Physics in 1903.
Pierre’s life was cut short in 1906 when he was knocked down and killed by a carriage. Marie took over his teaching post, becoming the first woman to teach at the Sorbonne, and devoted (献身于) herself to continuing the work that they had begun together. She received a second Nobel Prize, for Chemistry, in 1911.
The Curies’ research was important in developing X-rays in surgery. During World WarⅠ, Marie helped fixed X-ray equipment, which she herself drove to the front lines. She helped train doctors for the International Red Cross.
Although she achieved much success, men scientists in France were still against Marie, and she never received any financial help from her work. By the late 1920s her health was beginning to become worse. She died on 4 July 1934 from her dangerous research. The Curies’ eldest daughter Irene was a scientist and winner of the Nobel Prize for Chemistry.
1.All the following people contributed to Marie’s first Nobel Prize EXCEPT _____.
A．Irene B．Pierre C．Becquerel D．Roentgen
2.We can know from the text that Marie’s work______.
A．won her respect from men scientists

When thinking about placing a human being in space, one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment. The cold of space will freeze skin in a short time. The fierce heat of the sun can cause serious burns. The lack of atmosphere can cause gases in the body to expand(扩大) and even burst. With no oxygen to breathe, a human being will die in only a few moments. Radiation from the sun is another risk in space. So is damage from small pieces of rock and objects like meteoroids (陨石).
In 1933, an American flyer, Wiley Post, designed one of the first successful devices to protect a pilot at extreme heights. It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.
Today, astronauts wear very different protective clothing. It lets them move, do useful tasks, and stay outside their spacecraft in comfort and safety for several hours. The spacesuit is called the shuttle extravehicular mobility unit or EMU. It was designed to endure longer and to permit more movement than earlier spacesuits.
The EMU has a number of parts that an astronaut can link together by using only one hand, which makes it possible for each astronaut to select the parts that fit correctly.
Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.
1.Which of the following is NOT mentioned about the dangers of space environment?
A. Lack of oxygen. B. Fierce heat from the sun.
C. Gases in the body. D. Radiation from the sun.
2.Which of the following statements is true, according to this passage?
A. Wiley Post designed the first protective clothing for astronauts.
B. Astronauts in earlier spacesuits had difficulty in moving, doing useful tasks and so on.
C. EMU has many parts that can be linked together by using two hands.
D. Special spacesuits have been used for exploration of the planet Mars.
3.The underlined word “endure” means _______.
A. provide B. move C. last D. live
4.The best title of the passage might be ______.
A. Space exploration
B. Astronauts’ flights
C. The Advantages of Spacesuits
D. The Development of Spacesuits

This is the SCIENCE IN THE NEWS, I'm Barbara Klein.
Animal experts say one of the world's most beautiful and rare kinds of big cat is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards (豹) still live free. The cats are also called Far Eastern leopards.
Recently, their number has been reduced by one, Some person shot a female Amur, then beat her to death. The animal's body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia.
An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past fives years. Mr, Collins said the death of even one adult female is a huge loss for the endangered cat, He noted that the killing reduces the possibility for cubs (幼兽) or young.
It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs, Four leopards were identified as females with cubs. In all, five or six cubs were recorded, Six to eight animals could not be identified.
Most of the land where the Amur leopard once lived was in China.New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts.
Mr. Pikuuov says adult Amurs need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard is for governments to provide protected spaces for wildlife.
1.This passage is probably from .
A.a magazine B.a newspaper report
C.a TV report D.a film
2.Why is the killing of an adult female a huge loss?
A.It could lead to the death of an adult male.
B.It means it can not give birth to the young any more.
C.11 is worth more money than a male.
D.There is only one adult female in the world.
3.The number of the Amur leopards in China is becoming smaller because of all the following EXCEPT .
A.new roads B.climate change
C.human hunting D.rare diseases
4.According to the experts the Amur leopards .
A.are living on plants B.are living in the zoo
