A PG-13 rating is a stricter warning by the Rating Board to parents to determine whether their children under age 13 should view the film. A PG-13 film may go beyond the PG rating in theme, violence, nudity (裸露), language, adult activities or other elements, but does not reach the restricted R category.

The theme of the film by itself will not result in a rating greater than PG-13, although activities shown in the film related to a mature theme may result in a restricted rating for the film. Any drug use will initially require at least a PG-13 rating. More than brief nudity will require at least a PG-13 rating, but such nudity in PG-13 rated film generally will not be sexually oriented. There may be violence scene in a PG-13 movie, but generally not both realistic and extreme or persistent violence.

A single use of one of the rude words in a film, though only as an expletive (感叹语), initially requires at least a PG-13 rating. More than one such bad word requires an R rating, as must even one of those words used in a sexual context. The Rating Board nevertheless may rate such a film PG-13 if, based on a special vote by a two-thirds majority, the Raters feel that most American parents would believe that a PG-13 rating is appropriate because of the context or manner in which the words are used or because the use of those words in the film is easily neglected.

1.What is the main goal of this passage?

A.To discuss various movie ratings.

B.To explain various movie ratings.

C.To explain the difference between PG-13 and R movie ratings.

D.To explain the PG-13 movie rating.

2.According to PG-13 rating, the theme of the movie __________.

A.has little impact on its rating

B.has a large impact on its rating

C.should be entertaining

D.should be suitable for children

3.From Paragraph 2, we can learn that drug usage __________.

A.should not be allowed in movies

B.is dangerous

C.makes a PG-13 rating necessary

D.is not appropriate for children under 13

4.What does a movie with two or more uses of bad words require?

A.A PG rating. B.A PG-13 rating.

C.An R rating. D.An NC-17 rating.

The police in Taiwan are unable to judge whether to treat it as an extremely clever act of stealing or an even cleverer cheat. Either way, it could be the perfect crime, because the criminals are birds — homing pigeons!

The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up. Then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.

There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however, may in fact be the work of an even lazier and more inventive criminal mind — one that avoids not only collecting money but going out to steal the car in the first place. Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an ad in the newspaper asking for help.

The theory is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded — under 3,000 Taiwanese dollars — seems too little for a car worth many times more.

Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. “We have more important things to do,” he said.

1.After the car owner received a phone call, he ________.

A. went to a certain pigeon and put some money in the bag it carried

B. gave the money to the thief and bad his car back in a park

C. sent some money to the thief by mail

D. told the press about it

2.The “lazier and more inventive” criminal refers to ________.

A. the car thief who stays at home　　 B. one of those who put the ads in the paper

C. one of the policemen in Changwa　　 D. the owner of the pigeons

3.The writer, mentions the fact that “none of the stolen cars have been returned” to show ________.

A. how easily people get fooled by criminals

B. what Chen thinks might be correct

C. the thief is extremely clever

D. the money paid is too little

4.The underlined word “they” in the last paragraph refers to ________.

A. criminals　　 B. pigeons　　 C. the stolen cars　　 D. demands for money

5.We may infer that the criminal knows how to reach the car owners because ________.

A. he reads the ads in the newspaper

B. he lives in the same neighborhood

C. he has seen the car owners in the park

D. he has trained the pigeons to follow them

Most of us have looked up at the stars that fill the night sky and wondered whether we’re alone in the universe. Indeed, the question of whether there’ s life out there has been something humankind ’s been asking itself for countless years. But thanks to China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

The telescope has a huge round reflector, which measures 500 meters across and has a perimeter（周长）of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST’s designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. “Panels can change their positions through connected wires and parallel （关联的） robots. We can control their position with an accuracy of 1 mm,” Zheng Yuanpeng, chief engineer of the telescope’s panel project, told Xinhua News Agency.

FAST’s engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. “There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST’ s construction, told Xinhua.

And although it wasn’t yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars （脉冲星） have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.

1.What is the purpose of mentioning the question in Paragraph 1?

A.To introduce the new giant telescope.

B.To explain why there is life in universe.

C.To remind readers to think about the life in space.

D.To emphasize the question that should be answered.

2.What can we know from Paragraph 2?

A.The telescope is made up of many panels.

B.The area of FAST is about 800 square kilometers.

C.The engineer can handle FAST’s position accurately.

D.The individual panel helps scientists catch radio signals.

3.Why was FAST built in Guizhou?

A.Because Guizhou is a remote province.

B.Because Guizhou has an ideal valley.

C.Because Guizhou has beautiful mountains.

D.Because Guizhou has the ability to build it.

4.What does the last paragraph mainly talk about?

A.FAST’s timeline. B.FAST’s future.

C.FAST’s operation. D.FAST’s discoveries.

An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States，the legal blood alcohol limit is 0.08% for people aged 21 years or older，while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result，a result over the legal limit，allows the police to arrest the driver.However，many people who tested positive on the test have claimed that they only drank a “non­alcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT？Researchers in Missouri set up an experiment to find out.

First，the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks，the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.

For 11 of the 27 energy drinks，the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However，alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks，the more likely a positive alcohol reading will be obtained.
