There are various reasons why cancers appear to be on the increase. For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis (诊断), doctors can more easily recognize cancerous growths that would formerly have passed unnoticed or that would have been wrongly diagnosed. It is also believed that certain habits and conditions of modern living, including heavy smoking and the pollution of the air, may leave people living in more cancer-causing conditions than before.
We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examination of the blood.
Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.
The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.
The test examines very small bits of fat in the blood called lipids (脂质). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.
The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.
1.Who will fail cancer from the study of the researchers?
A. The young. B. The middle age and the older.
C. The man. D. The woman.
2.The underlined words "such a test" refer to ________.
A. the test that shows which persons have cancer and which don’t
B. the test that may be able to show cancer very early in its development
C. a simple medical test that cannot find cancer when it is small
D. a new test that could be a step to develop a difficult way
3.Which of the following statements is true according to the passage?
A. Cancers have much to do with something in patients’ blood.
B. People living in better conditions are most likely to be attacked by cancer.
C. X-raying is the best way to determine whether a person has cancer or not.
D. Cancers have nothing to do with a person’s habits and living conditions.
4.What would be the best title for the passage?

During her sixty-year career performing, Lena Horne entertained people with her beauty and rich, emotional voice. She used her fame to fight social injustices toward African-Americans.
Lena Horne was born in New York in 1917. At sixteen, Lena became a dancer at the famous Club in New York City. After taking voice lessons, she soon became a singer. In 1940, Lena Horne became the first African-American to perform with an all-white jazz band. After performing at a club in Hollywood, California, she caught the attention of filmmakers. She soon began making movies. Her films became very popular. In the 1940’s, Lena Horne was the first African-American in Hollywood to sign a long-term contract with a major movie studio. Her deal with MGM stated that she would never play the role of a servant. She refused to play roles that represented African-Americans disrespectfully(无礼的). But this refusal also limited her movie career.
Lena Horne once said that World War Two helped make her a star. She was popular with both black and white soldiers. She sang on army radio programs and traveled to perform for the troops. Once, she noted that German prisoners of war were permitted to sit closer to the stage than black soldiers. She was very angry. These experiences led to Lena Horne’s work in the civil rights movement.
Lena Horne sang at civil rights gatherings. She took part in the March on Washington protest in 1963. It was during this event that Martin Luther King Junior gave his “I Have a Dream” speech. She protested racial separation at the hotels where she performed. She took action so that she and her musicians would be allowed to stay in those hotels.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don’t have oxygen(氧). They’re multicellular(多细胞的), which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals.
The most exciting thing about these creatures, say the scientists, is that they obviously don’t need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms(有机物) can visit these places, but not live there. These newly found creatures could change that idea.
Finding animals down there was so surprising that the scientists couldn’t believe it. At first, “we thought they were dead bodies,” Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples(样本) from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive.
The researchers did more tests, and found that some of the animals had eggs—which suggests they were reproducing(繁殖). Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen.
These clues suggest the animals don’t need oxygen, but the evidence(证据) is indirect, which means that scientists still have not observed how the animals live without oxygen. This means more studies are needed, but the scientists think they’re on the right track. And if they’re right, biologists will need to rethink what they know about where animals live.
1.What excited the scientists most is that ______.
A.they found three animal species visit the salty water under the Mediterranean Sea
B.single-celled animals can live in super-salty waters
C.the tiny animals have many cells
D.three kinds of animals can live in places that have no oxygen
2.The underlined phrase in Paragraph 2 means the scientists could think _____.
A.only single-celled creatures don’t need oxygen to live
B.multicellular animals can visit the super-salty waters
C.the newly found creatures can’t live in the super-salty waters
D.multicellular animals also can live without oxygen besides single-celled ones
3.Which of the following CAN’T be used to prove the newly found creatures can live in super-salty waters?
A.Their dead bodies are found there.
B.Some in the samples have eggs.
C.Some old skins are found in the samples.
D.The pictures of their insides have been taken.
4.More studies are needed to prove_____.
A.where single-celled animals can live
B.how the newly found animals live without oxygen
C.whether the multicellular creatures can live underwater
D.why the super-salty waters have no oxygen

Most people watching Jeremy Lin these past two months saw Jeremy Lin，New York Knicks star；but I，watching him，saw someone else.That was my elder brother，Bob，who is athletic and energetic. He could never sit still when he was in second grade；he had to get up every now and then and run around the room.And sure enough，he grew up to be a starting player for an NCAA championship lacrosse (长曲棍球) team.He was a Nikeendorsed marathoner，too，and reached the top of Mt.Everest，unguided，in his 50s.
And yet my family never watched his lacrosse games.We did watch some of his marathons，but that wasn’t until he was in his 20s.When Bob was in his glory days，our Shanghaineseborn parents were bent on getting him into medical school.There was a loving aspect to it：I can remember my father working through math books with him，lesson by lesson，at the big blackboard in the attic.Bob never did become a doctor，though；and neither did I．It wasn’t until my younger sister came along that someone in the family finally wore a white coat.
Bob today could be the fittest 58yearold on the planet.His doctor estimates his biological age at 35；he’s still big mountains in the Himalayas.And，like Jeremy Lin，he’s charming.No one sees Bob without leaving with a laugh.He sometimes jokes he could be mayor of his building，and it’s true.To know him is to cheer for him.
And yet my parents did not cheer for him.What if my mother had sat on the sidelines with her statistics，like Jeremy Lin’s mother？What if my father had played videos of athletes for my brother to watch and imitate？It’s hard not to wonder.
And how did Jeremy Lin’s parents manage to do these remarkable things？Amy Chua，the tiger mother，recalls her immigrant father beating the kids whenever they mispronounced a Chinese word.How is it that Jeremy Lin’s immigrant father in particular，GieMing Lin，encouraged his son to follow such an untraditional path?
1.Bob’s glory days were those ________.
