Expressions about water are almost as common as water itself. But many of the expressions using water have unpleasant meanings.
The expression “to be in hot water” is one of them. It is a very old expression. “Hot water” was used 500 years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle．
That no longer happens. But we still get in “hot water”. When we are in “hot water”, we are in trouble. It can be any kind of trouble---serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother if he walks in the house with dirty shoes．
Being in “deep water” is almost the same as being in hot water. When you are in deep water, you are in a difficult position. Imagine a person who cannot swim being thrown in water over his head. You are in deep water when you are facing a problem that you do not have the ability to solve. You can be in deep water, for example, if you invest in stocks without knowing anything about the stock market.
“To keep your head above water” is a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job．
“Water over the dam” is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again．
Another common expression, “to hold water”, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container. If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes. If it does not hold water, then it is weak and not worth debating.
“Throwing cold water” also is an expression that deals with ideas or proposals. It means that one doesn’t like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea because she says a new car costs too much.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline（下降） when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s. “This gender（ 性别） difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age. The underlined word “longevity” in the second paragraph probably refers to “________”.
| A．health | B．ageing | C．long life | D．effect |
The text mainly talks about ________.
| A．men’s heart cells | B．women’s ageing process |
| C．the gender difference | D．hearts and long life |
According to the text, the UK scientists have known that ________.
| A．women have more cells than men when they are born |
| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |
| D．women never lose their pumping power with age |
If you want to live longer, you should ________.
| A．exercise regularly to keep your heart healthy |
| B．find out the reason for ageing |
| C．enable your heart to beat much faster |
| D．prevent your cells from being lost |
We can know from the passage that ________.
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn’t think twice before diving into the freezing East River.
Tuesday’s Daily News said 29-year-old Julien Duret from France was the man who left the spot quickly after the rescue last Saturday.
He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum. He handed the girl to her father, David Anderson, who had dived in after him.
“I didn’t think at all,” Duret told the Daily News. “It happened very fast. I reacted very fast.”
Duret, an engineer on vacation, was walking with his girlfriend along the pier(码头) when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water.
When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she opened her eyes.
Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came later for her, said Duret, who was handed dry clothes from onlookers. Duret caught a taxi with his girlfriend shortly after.
The rescue happened on the day before he left for France. Duret said he didn’t realize his story of heroism had greatly moved New York until he was leaving the city the next morning.
“I don’t really think I’m a hero,” said Duret. “Anyone would do the same thing.”Why was Duret in New York?
| A．To meet his girlfriend. | B．To spend his holiday. |

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.
Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.
Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.
The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.
Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.
| Brief 1 |
People living in a particular 2 usually have the same skin color and there are many different skin colors in the world. |
| Reason for skin color |
The reasons for different skin colors mainly 3 in biology and history. |

Melanin 10 an important role in our skin color. With our living environment changing, melanin production is changed, which leads to the changes in our skin color. |
Smart phones that react to your moods and televisions that can tell it’s you who’s watching are in your future as Intel Corporation’s top technology expert sets his sights on context-aware computing.
Chief technology officer Justin Rattner showed how personal devices will one day offer advice. “How can we change the relationship so we think of these devices not as devices but as assistants or even companions?” he asked.
Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give.
“Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, ” Rattner said, “Future devices will constantly learn about who you are, how you live, work and play.’’
Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer’s entertainment preferences.
As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple’s iPhone and Research in Motion’s Blackberry.
Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices.
The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC.
“I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future,” Rattner said.
But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.
Rattner recognized that questions about privacy and people’s willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off.
“If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.”, he said.The future smart phones can do all of the following except _______.
| A．giving responses to the moods of the owners |
| B．giving proposals like assistants or companions |
| C．offering advice to their owners’ friends or relatives |
| D．telling the phone holders or carriers where they are |
Which of the following are smart phones according to the passage?
| A．iPhone and Blackberry | B．LG and Samsung |
| C．Marvell and Qualcomm | D．Nvidia and ARM Holdings |
From the passage we can infer that _______.
| A．Intel Corporation has become the world leader in the smar tphone market |
| B．Intel Corporation has fallen behind in the profitable market for smart phones |
| C．more functions packed into mobile phones will make mobile devices larger |
| D．the smart phone industry is likely to grow 25 percent in the year of 2011 |
The best title for the passage is likely to be _______.
| A．Smart phones and Televisions | B．Context-aware Computing |
| C．Personalized Televisions | D．Personalized Smart phones |
