Be careful when you cross this busy street. ________, you may get run over by a car.

A. If not B. If so C. If any D. If possible

 

A

【解析】

试题分析:考查省略。句意:当你穿过这条繁忙的街道时要小心。如果不小心的话,你可能会被汽车撞到。当if从句的主语跟主句主语一致,且谓语是be的某种形式时,if从句常省略主语和be动词。这里的if not相当于if you are not,故选A

考点:考查省略

A 16-year-old boy finds himself on a boat in the Pacific Ocean after escaping a shipwreck(海难). Even worse, he is left with a huge tiger for company. But he manages to survive after 227 days of fighting against all the hardships of the sea.

Pi, the lead character in Oscar-winning Ang Lee’s new movie Life of Pi, went through an inspiring journey of growth and self-discovery. So did 19-year-old Suraj Sharma, the Indian actor who plays him.

But it was a lucky chance that opened up the opportunity for the new star. Sharma was a regular student who lived with his mathematician parents in Delhi, India. As the director traveled to Mumbai to find his Pi, the teenager went along with his younger brother, who had acted in a couple of movies, to audition(试镜). But little did Sharma know that he would end up winning the role from 3, 000 hopefuls.

Lee said he saw Pi in Sharma: “Not only does he have a compelling and wise look. He has this rare talent.” The director said that in the final round, Sharma gave one of the “most compelling readings we had. In the end, he was in tears.” Understandably, Sharma didn’t want to let Lee down. “He (Lee) had given me this opportunity. I had to give it my best,” Sharma told the Philippine Daily Inquirer.

Sharma swam for four or five hours a day until he was completely comfortable with the water. He also worked on his body because he had to first gain weight and then quickly lose weight as the story developed. He even had rats run all over him to prepare for his role. Lee was impressed by the teenager, especially his endurance and patience in staying in a water tank for many hours each day. Sharma was only 16 when Lee signed him. After three years of shooting, Sharma said he had matured with Pi’s journey.

You have probably heard of the Mozart effect. It’s the idea that if children or even babies listen to music composed by Mozart, they will become more intelligent. A quick Internet search reveals plenty of products to assist you in the task. Whatever your age there are CDs and books to help you taste the power of Mozart’s music, but when it comes to scientific evidence that it can make you more clever, the picture is more mixed.

The phrase “the Mozart effect” was made up in 1991, but it was a study described two years later in the journal Nature that sparked real media and public interest about the idea that listening to classical music somehow improves the brain. It is one of those ideas that sound reasonable. Mozart was undoubtedly a genius himself; his music is complex and there is a hope that if we listen to enough of it ,we’ll become more intelligent.

The idea took off, with thousands of parents playing Mozart to their children, and in 1998 Zell Miller, the Governor of the state of Georgia in the US, even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music. It was not just babies and children who were exposed to Mozart’s music on purpose, even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them to produce better milk.

I’ll leave the debate on the impact on milk yield to farmers, but what about the evidence that listening to Mozart makes people more intelligent? More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally, but the benefits are short-lived and it doesn’t make us more intelligent.

1.What can we learn from paragraph 1?

A. Mozart composed many musical pieces for children.

B. Children listening to Mozart will be more intelligent.

C. There are few products on the Internet about Mozart’s music.

D. There is little scientific evidence to support Mozart effect.

2.Why did many people believe in the idea of Mozart Effect?

A. Because a study described it in the journal Nature.

B. Because Mozart himself was a genius.

C. Because Mozart’s music is enjoyable.

D. Because Mozart’s music makes people relaxed.

3.The underlined sentence in paragraph3 suggests that .

A. people were strongly against the idea

B. the idea was accepted by many people

C. Mozart played an important part in people’s life

D. the US government helped promote the idea

4.What is the author’s attitude towards the Mozart effect?

A. FavorableB. ObjectiveC. DoubtfulD. Positive

5.What would be the best title for the passage?

A. Listening to Mozart , necessary? B. What music is beneficial?

C. What is the Mozart effect? D. To be or not to be?
