Things similar continuously happened in Haiti and Chile.Thousands of people were
buried in the earthquake and lost their fives.What if we could have warned them? People are always trying hard to find a way of pr
eventing building collapsing(坍塌).Better materials and technology help,but are not a solution.Just like humans,a building has its own life circle from “birth” to “death”.If we know when a building is going to collapse,we can repair it in advance or get out before it falls.
Now, scientists at the University of Illinois have developed a material that turns red before it breaks.The invention could be used in things like climbing ropes,or bridge supports.The secret behind the color-changing material is a type of molecule(分子).A molecule is a group of atoms held together by chemical bonds(化学键).Imagine you and your friends standing in a circle,holding hands.Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule.If one person lets go of his or her hands,the molecule changes color.The research team put the molecule into a soft material.When the researchers stretched(拉长) the material:it turned bright red a few seconds before it broke into two pieces.
When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red.
The major problem is,light can get rid of the red color.When the team shone a bright light on the molecule,the broken bond was fixed,and the color disappeared.If bright fight keeps the red color from appearing,the material’s warning system will be useless.Scientists still have a lot of work to do before the color-changing molecule can be used outside the lab. The passage mainly about
| A.a way of preventing building from breaking down |
| B.a series of earthquakes in Haiti and Chile |
| C.a way of warning before buildings collapse |
| D.a newly-discovered structure of a molecule |
According to the passage,we can conclude that
| A.there are problems to solve before putting the new material to use |
| B.scientists have found the life circle of buildings from “birth” to “death” |
| C.bright fight makes the red color visible to human eyes |
| D.the new material is unlikely to be used in building bridges |
The color-changing molecule can
| A.make building materials much stronger |
| B.help building materials get stretched if necessary |
| C.prevent the earthquake from killing people |
| D.remind people to leave buildings before they fall |
The warning system is based on the fact that
| A.red color won’t show up when it meets bright fight |
| B.a material with a certain type of molecule Can turn red when stretched etched |
| C.a building has its own life circle of “birth” to “death” |
| D.the broken bond will fix itself when a molecule meets bright fight |
Do American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting. But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for 10 to 15 minutes a day, and then other teachers who basically teach it for 60 to 70 minutes a day—which really for handwriting is pretty much.
Many adults remember learning that way—by copying letters over and over again. Today’s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself. Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.
Handwriting involves two skills. One is legibility, which means forming the letters so they can be read. The other is fluency—writing without having to think about it. Fluency continues to develop up until high school.
But not everyone masters these skills. Teachers commonly report that about one fourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.
But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, which connects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75 percent of students choose to print their essay on the test rather than write in cursive.Which of the following is WRONG for traditional handwriting in the USA?
| A.The students are taught by practicing a long period. |
| B.The letters are repeated many times. |
| C.Handwriting includes two skills. |
| D.To write in cursive is taught first. |
The underlined word “legibility” in Paragraph 3 means _____.
| A.easy to read |
| B.complex |
| C.unexpected |
| D.unreadable |
The best title for the passage is _____.
| A.How to improve handwriting in school |

| C.Handwriting involves two skills |
| D.Handwriting lessons are on the way out |
The author’s attitude towards whether still to learn handwriting in school is _____.

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of the country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people of a destination(旅游目的地) country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism. People can lose jobs. Businesses can also lose money. It casts a great deal of money to build large hotels, airports, first-class roads, and other support facilities(配套设施) needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many other support facilities as well, including roads to get to the hotel, electricity, sewers(下水道)to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.Which of the following do you think has been discussed in the part before this selection?
| A.It is extremely important to develop tourism. |
| B.Building roads and hotels is important. |
| C.Support facilities are highly necessary. |
| D.Planning is of great importance to tourism. |
The underlined word “inhabitants” (in Paragraph 1) probably means “_____”.

It can be inferred from the text that _____.
| A.the author doesn’t like tourism developing so fast |
| B.local people will benefit from tourist attractions |
| C.other parts of a country’s economy won’t benefit from tourism much |

For those who make journeys across the world, the speed of travel today has turned the countries into a series of villages. Distances between them appear no greater to a modern traveler than those which once faced men as they walked from village to village. Jet planes fly people fro one end of the earth to the other, allowing them a freedom of movement undreamt of a hundred years ago.
Yet some people wonder if the revolution in travel has gone too far. A price has been paid, they say, for the conquest(征服) of time and distance. Travel is something to be enjoyed, not endured(忍受). The boat offers leisure and time enough to appreciate the ever-changing sights and sounds of a journey. A journey by train also has a special charm about it. Lakes and forests and wild, open plains sweeping past your carriage window create a grand view in which time and distance mean nothing. On board a plane, however, there is just the blank blue of the sky filling the narrow windows of the airplane. The soft lighting, in-flight films and gentle music make up the only world you know, and the hours progress slowly.
Then there is the time spent being "processed" at a modern airport. People are conveyed like robots along walkways; baggage is weighed, tickets produced, examined and produced yet again before the passengers move to another waiting area. Journeys by rail and sea take longer, yes, but the hours devoted to being "processed" at departure and arrival in airports are luckily absent. No wonder, then, that the modern high-speed trains are winning back passengers from the airlines.
Man, however, is now a world traveler and cannot turn his back on the airplane. The working lives of too many people depend upon it; whole new industries have been built around its design and operation. The holiday-maker, too, with limited time to spend, patiently endures the busy airports and the limited space of the flight to gain those extra hours and even days, relaxing in the sun. Speed controls people’s lives; time saved, in work or play, is the important thing –or so we are told. . Perhaps those first horsemen, riding free across the wild, open plains, were enjoying a better world than the one we know today.
