Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (靈學(xué)家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists, Robert Baker, a psychologist at the University of Kentucky, performed two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind a two way mirror in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t. and they were no better at telling when they were stared at than if they had just guessed.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said baker, “I suggest they repeat the experiments and see for themselves.”
【小題1】The purpose of the two experiments is to                                 .

A.explain when people can have a sixth sense
B.show how people act while being watched in the lab
C.study whether humans can sense when they are stared at
D.prove why humans have a sixth sense
【小題2】In the first experiment, the subjects                             .
A.were not told that they would be stared at
B.lost their sense when they were stared at
C.were not sure when the would be stared at
D.were uncomfortable when they were stared at
【小題3】What can be learned from the passage?
A.People are born with a sixth sense.
B.The experiments support parapsychologists’ idea.
C.The subjects do not have a sixth sense in the experiments.
D.People have a sixth sense in public places.

    Ball Management

Players should always keep a tennis ball in their hand or pocket during a match. Even the most patient tennis players despise waiting for their opponent to find a ball to serve(發(fā)球).

Behavior & Attitude

Even if you’re playing badly, you should not shout or look depressed in a friendly match. Undoubtedly, your attitude affects how you play, so try to have fun and stay positive.

Pace

Do not deliberately slow the game down. Play at the pace of the server and look ready. Servers also should not rush to start each point. You should re-do the point if you serve the ball before the receiver is ready. The receiver is out of luck, however, if he claims he was not ready after making an attempt at returning the serve.

For Spetators(觀眾)

Cheering

While it is seen as proper etiquette(禮儀)to remain silent during the live play, loud and spirited cheers are welcome after a hard-earned point. The players appreciate the recognition for their efforts and are encouraged to continue playing at a high level when the crowd is actively involved.

Leaving and returning to your seat

During live play it’s expected that all spectators will remain seated until the next break between games. Movements in the stands(看臺) can serve as a distraction(分心的事物) to the players and can also block the view of other audience.

Photography

The issue of camera shutter(快門) noise has earned a lot of attention in golf, but luckily for tennis fans it’s much less of a concern on the court. While the noise produced by the camera is not seen as a major issue, flash photography should be avoided during live play.

1.During warm-ups, tennis player ______________.

A. ought to hit a full pace

B. can place their shots anywhere

C. should not practice competitively

D. had better run around the whole court

2.According to the text, during tennis matches, _____________________.

A. players can slow the game down when tired

B. players don’t have to keep a ball in their hand

C. the receiver shouldn’t return the serve if not ready

D. loud cheers are not allowed even after hard-earned points

3.It can be inferred from the last paragraph that ____________________.

A. flash photography is acceptable on the golf court

B. tennis fans can use flash photography during matches

C. the noise from cameras is not permitted in tennis matches

D. tennis matches require a less degree of quiet than golf ones

4.What’s the text mainly about?

A. Some tips for tennis players to win a match.

B. What to do while watching tennis matches.

C. How to behave properly in tennis matches.

D. Rules tennis players must obey in matches.

科目:高中英語 來源:2012-2013學(xué)年浙江省高三回頭考試英語試卷(解析版) 題型:閱讀理解

When I was seven my father gave me a Timex, my first watch. I loved it, wore it for years, and haven’t had another one since it stopped ticking a decade ago. Why? Because I don’t need one. I have a mobile phone and I’m always near someone with an iPod or something like that. All these devices(裝置)tell the time—which is why, if you look around, you’ll see lots of empty wrists; sales of watches to young adults have been going down since 2007. 

But while the wise have realized that they don’t need them, others—apparently including some distinguished men of our time—are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling command shocking prices, up to £250.000 for a piece.

This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days all watches tell the time as well as all other watches. Expensive watches come with extra functions—but who needs them? How often do you dive to 300 metres into the sea or need to find your direction in the area around the South Pole? So why pay that much of five years’ school fees for watches that allow you to do these things?

If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead the Swiss reinvented the watch, with the aid of millions of pounds’ worth of advertising, as a message about the man wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world. 

Watches are now classified as“investments”(投資). A 1994 Philippe recently sold for nearly £350, 000, while 1960s Rolexes have gone from £15, 000 to £30, 000 plus in a year. But a watch is not an investment. It's a toy for self-satisfaction, a matter of fashion. Prices may keep going up—they’ve been rising for 15 years. But when fashion moves on, the owner of that £350, 000 beauty will suddenly find his pride and joy is no more a good investment than my childhood Timex. 

1.It seems ridiculous to the writer that_______________. 

A.people dive 300 metres into the sea

B.expensive clothes sell better than cheap ones

C.cheap cars don’t run as fast as expensive ones

D.expensive watches with unnecessary functions still sell

2.What can be learnt about Swiss watch industry from the passage?

A.It’s hard for the industry to beat its competitors.

B.It targets rich people as its potential customers.

C.It wastes a huge amount of money in advertising.

D.It’s easy for the industry to reinvent cheap watches.

3.Which would be the best title for the passage?

A.Watches? Not for Me!

B.My Childhood Timex

C.Timex or Rolex?

D.Watches—a Valuable Collection
