How is quicksand formed? Water pushes up from below the surface and is held by the sand. The grains of sand are forced apart by the water. They cannot hold any weight. The subsurface water may have come from a spring, a river, or a stream. Sometimes pools of water near beaches become filled with sand. When the soil under these pools does not allow for good drainage(排水), the sand can become stretches of quicksand.
Is it true that a person who steps into quicksand is doomed to die? No, for people have fought their way from quicksand to firm land again. It is panic(恐慌) that creates the condition that can result in death, for the more a person struggles, the worse matters become. Quick movements will make the sand yield for a time, but then it rushes back and settles solidly around the body.
People trapped in quicksand should either lie back with arms outstretched, or not move at all. When the weight of the sand around his body has displaced equals that person’s weight, the victim will stop sinking. With feet held still, and with slow movements of the arms, as in the backstroke(仰泳) in swimming, people have managed to roll to safety and reach firm ground.
小题1:Quick movements by a person trapped in quicksand will _______.
A.help the person reach firm ground |
B.help prevent panic |
C.make the same sand yield temporarily |
D.make the sand hold the person’s weight |
A.a mass of fine sand mixed with water | B.formed only along rivers |
C.found below subsurface water | D.solid ground |
A.Stretches of quicksand are found only under the sea. |
B.People should never try to escape from quicksand. |
C.It is hard to keep calm if you fall into quicksand. |
D.Only heavy people can be trapped in quicksand. |
A.what solid ground looks like | B.the nature of quicksand |
C.stepping into quicksand | D.escaping from quicksand |

An Australian study of 270,000 students found that both boys and girls performed much higher on standardized(标准化) tests when they attended separate schools. During an experiment in Virginia in 1995, 100 eighth graders were separated just for math and science courses. Almost immediately, the girls began to achieve more, become more confident and take part more often in class activities.
In 2001, a British study concluded that nearly every girl regardless of (不论) her ability or socio-economic status performed better in single sex classrooms than co-ed ones. The study of 2,954 high schools and 979 primary schools showed that while boys at the lowest levels in study improved the most in single sex schools, single sex education was particularly beneficial (有益的) to girls. Every one of the top 50 private elementary schools and top 20 private high schools in Britain are single sex schools.
Girls became more confident in themselves as students and earned higher scores on their College Board and Advanced Placement examinations. A quarter of the female members of the US Congress and one-third of all female members of Fortune 100 boards graduated from all-women’s colleges.
While the statistics are not as dramatic for boys, however, boys tend to soften their competitive edge and become more cooperative in a single sex setting. They can just be boys and not worry about what the girls might think.
Single sex education has a pleasant way of encouraging children to be fearless, to be curious, to be enthusiastic --- in short, to just be themselves. Children are subjected (屈从于) to pressures from every quarter to become adults before they are ready to do so. They grow up too quickly. Why not let them be children for a few more years? Single sex education with its gentler, more controlled social atmosphere is just the right answer for many children.

“Finally.” read the big headline Thursday above a picture of the white phone on the homepage of Apple. com.
The white model was supposed to ship alongside the black one at the iPhone 4’s launch(推出) last June. But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.
As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash(闪光灯) was used. Its whiteness confused the proximity sensor (距离传感器) , which detects when the phone is held next to someone’s head and turns off the touch screen to save battery life.
These problems weren’t present in older iPhones that came in white because they didn’t have flash photography; the proximity sensor was unaffected because the front side of previous models was black.
“We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren’t,” Philip Schiller, Apple’s chief marketing executive, said in an interview. “It’s not as simple as making something white. There’s a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors. “
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple’s phones. He says Apple could sell 1 million to 1. 5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.
Forty-five people were lined up at Apple’s flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.

According to the passage, which of the following statements is TRUE?
A.There are multi-colored models of iPhone 4. |
B.The same design problems were also found in older white iPhones. |
C.IPhone4 will be launched this fall. |
D.Originally designers thought they could solve the problems before iPhone 4 was launched. |
What would be the best title for this passage?
A.Why the White iPhone 4 Took So Long |
B.The History of iPhone 4 |
C.The Attraction of White iPhone 4 |
D.The Design and Manufacture of iPhone 4 |
What does the underlined word “unveil” in the last paragraph mean?
A.to remove one’s mask from his face |

The person would reply, “Not so good today, Henderson. You see, it’s this summer heat. I just hate it. It just makes me tired. It’s almost killing me.’ Then my grandmother would stand calmly, her arms folded, and say, “Uh-huh, uh-huh.”
As soon as the complainer was out of the store, my grandmother would call me to stand in front of her. Then she would say the same thing she had said at least a thousand times, it seemed to me. “Jane, did you hear what so-and-so complained about?” And I would nod. Grandmother would continue, “Jane, there are people who went to sleep all over the world last night, poor and rich and black and white, but they will never wake again. Those dead people would give anything, anything at all for just five minutes of this weather that person was complaining about. So you watch yourself about complaining, Jane. What you’re supposed to do when you don’t like a thing is change it. If you can’t change it, change the way you think about it. Don’t complain.”
I have learned a lot from my grandmother. Her opinions always hit the nail on the head. Whining is not only impolite, but can be dangerous.
小题1:

A.think little of themselves | B.enter a store regularly |

A.she tried to comfort the whiners | B.she was impolite to the whiners |
C.she was against whining | D.she shared the whiners’ opinions |
The author’s grandmother told her to ________.

Buy or borrow a lot of “fun” books. Choose books that are slightly below his level of reading ability. Don’t forget what your child likes to do when choosing books for him. Don’t comment about the books. Simply leave the books lying on the table where your child is sure to see them. Computer games are not as harmful as most parents usually think them to be. Instead, you should take advantage of your child’s love of computer games to purchase those that require a lot of reading and avoid those that are simply computerized video games.
Buy your child a bedside reading lamp, or a tiny book light. Tell him that from now on, he must be in bed by a specific time (say 8:30) and that he can either sleep or read. Most kids will do anything else rather than go to sleep, so there’s a chance you’ll create a new bedtime reading habit.
Many children will read when they are sitting alone having a snack, or when they have a few minutes of unplanned free time. Put a box of books and magazines near the kitchen table so that reading material is available.
Often, once children learn to read independently, parents stop reading to them. This change of routine causes great sadness to a child who has come to love falling asleep as you read. Even a teenager will enjoy being read to if you pick books that interest him. Select books together, and make sure they’re ones you enjoy as well, so your enjoyment will come through as you read to them.
小题1:
To make children become interested in reading, parents should _______.
A.choose books based on their interest |
B.tell them what they can learn from these books |

The main idea of the passage is to ________.
A.help children succeed in school subjects |
B.give parents advice on how to educate children |
C.remind parents of the importance of reading |
D.teach parents how to encourage children to read |
On television, in newspapers and through the Internet, we learned about the extent (巨大,重要性) of the destruction, and the statistics were horrific – over 69,000 confirmed (确认) dead, some 18,000 missing and more than 374,000 injured.
When we turn off the television and discuss what we as a family have learned from the events of the last several weeks, we find ourselves marveling (觉得惊奇) at how the Chinese are confidently but quietly dealing with this unprecedented tragedy – a disaster that continues with every aftershocks, mudslide and potential flood.
It seems like every school, organization and business is raising money for Sichuan, and young people all over the country are out in the streets looking for donations or giving blood at the many mobile blood vans that are out in full force.
Those who cannot give, like the 75-year-old woman from Sichuan, are volunteering or giving in other ways. An impressive example is the Sichuan policewoman with a newborn child who was nursing many infants whose mothers were killed in the quake.
The national concern over the fate of affected children has been moving. On May 22, there were 1697 orphans, but on June 24, the number dropped to 558; and rest assured, there are more people willing to adopt than there are orphans from Sichuan.
So, while no country or person ever welcomes tragedy, especially something of this magnitude (程度), the earthquake has taught us a great deal about China’s true character and its people’s resilience (韧性). It has also reminded us that the other side of even a dark coin may hold the promise of a brighter future,
(The author is an American Professor of International Relations at Xi’an Jiaotong University.)

A.a dark side and a bright one of a coin |
B.the unprecedented tragedy and China’s true character |
C.the dead and the victims in the earthquake |
D.the destruction and the donations |
