【題目】閱讀理解
In Los Angeles, drivers spend sixtyone hours every year stuck in traffic. These drivers know too well how bad the traffic can be. “There're too many cars, and you can't move around a lot.”
Professor Cyrus Shahabi also knows about traffic jams. He lives more than 65 kilometers from his office at the University of Southern California in Los Angeles. He is always late even with the help of a navigation (導(dǎo)航) system.
He decided to develop a program called ClearPath for that. He says his program uses historical data to predict traffic conditions even before the driver leaves the house.
“What's unique is that we use a lot of data that's currently become available including traffic data, weather data, and we analyze that so that we can predict what's going to happen in front of you when you leave home.”
Professor Shahabi says his system does more than just respond to current traffic conditions. With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the fastest route. It looks at the entire road network, including surface streets as well as highways, before the driver hits the road. Professor Shahahi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities.
“I always thought that Los Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this.”
Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple.
（1）Drivers in Los Angeles were mentioned in order to ________.
A.show care for them
B.introduce their life
C.solve traffic problems
D.raise the topic
（2）What is unique about ClearPath?
A.It can use a lot of information all over the world.
B.It can ensure that you will never be late for work.
C.It helps drivers see clearly what happens on the road.
D.It helps drivers know the road conditions ahead of time.
（3）The underlined word “hits” in the fifth paragraph probably means ________.
A.have an accident
B.get to
C.turn left or right
D.collect traffic data
（4）What's Professor Shahabi's attitude toward his invention?
A.Disappointed.
B.Proud.
C.Optimistic.
D.Worried.

【答案】
（1）D
（2）D
（3）B
（4）C
【解析】本文是一篇說明文。在洛杉磯，交通阻塞非常嚴重。賽勒斯·謝哈比教授決定開發(fā)一款名叫ClearPath的系統(tǒng)，這個系統(tǒng)可以利用歷史數(shù)據(jù)，在司機出發(fā)前就可以預(yù)測道路的交通狀況。 (1)D　推理判斷題。文章第一段提到洛杉磯的交通阻塞非常嚴重，洛杉磯的司機對這一交通情況十分了解，也感到很無奈。提到司機的目的是為了引出下文，提出本文的主題。故選D項。 (2)D　細節(jié)理解題。根據(jù)第四段“What's unique is that we use a lot of data that's currentlybecome available including traffic data, weather data, and we analyze that sothat we can predict what's going to happen in front of you when you leave home.”可知，ClearPath系統(tǒng)可以分析多種數(shù)據(jù)，提前預(yù)測道路交通狀況。故選D項。 (3)B　詞義猜測題。根據(jù)第四段內(nèi)容可知，在司機出發(fā)之前，這個系統(tǒng)會對路況進行分析。由此推斷，before the driver hits the road意為“在司機上路之前”，hit意為“到達”。故選B項。 (4)C　推理判斷題。根據(jù)第五段最后一句、第六段以及最后一段可知，謝哈比教授認為他發(fā)明的系統(tǒng)有希望應(yīng)用于全國乃至全世界各個國家，并且他希望能和一些公司分享自己的新發(fā)明。由此推斷，他認為新發(fā)明的前景很樂觀。故選C項。

Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. Sharks eat fish, other sharks, and plants that live in the ocean.
Sharks grow slowly. About forty percent of all sharks lay eggs. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old．Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.
Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too great.
People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable. Collectors pay thousands of dollars for the jaws of a shark. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth.
A. Shark liver oil is a popular source of Vitamin A.

Relax during a job interview
Fewpeople actually like job interviewing. It's nervewracking trying to showyour“best” self to a perfect stranger. That's not easy, but thereare some ways to pull yourself together and feel more confident.
Prepare solid talking points. It's always best to overprepare for possible questions by not only researchingthe company and the person interviewing you, but also by preparing answers andpracticing those responses. Review the skills and experiences requested in thejob announcement and have two to three examples of how you have demonstratedeach one.
Remember：It's a twoway street.This is a conversation, not an interrogation(審問).
Remembering that this is a back and forthdiscussion，whereyou can—and should—ask questions as well as answer them, can help you feel morecomfortable.
Just breathe. Your body will relax a lot. You wantto avoid upper chest breathing, as it tends to just move your stress upward toyour face.
Ifyou go into an interview picking apart your outfit or imperfect responses,you're only hurting your chances of coming off as calm and collected. Turn offyour negative selftalk and then create a different selftalk message，like “I am here to share the best ofmy ability and that is all I can really do.”
Work it out. Putting in some gym time on themorning of your interview can help you get rid of any nervous tension. Exercisehelps calm your nervous system and tends to reduce the intensity of physicalmanifestations(表現(xiàn)形式)of stress such as restlessness.
A．Stop the negative thoughts.
B．Put your idea into practice.
C．When faced with an interviewer, youmay be nervous.
D．Before you walk into your interview，take a few deep breaths.
E．You're trying to prove you're the onefor the job and that you can handle stressful situations.
F．Don't forget that you're not the onlyone being interviewed—you're also interviewing the organization.
G．This will strengthen your answers andallow you to show how your experience is relevant to the job or organizationfor which you're interviewing.
