Put an ice cube from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze(结冰) again.
After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.
【小题1】We must use when we carry out this experiment.
| A．a fridge | B．some food | C．a table | D．some salt |
| A．More than three minutes. | B．Five minutes or two. |
| C．Only one minute or two. | D．About ten minutes. |
| A．physics | B．biology | C．chemistry | D．maths |
On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaci found a message in DNA showing how DNA tells the cell（细胞）to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save more people from several illnesses.
Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited（限制）in use.
【小题1】When did we first know why we look like other people m our family?
| A．In 1860 | B．In 1953 | C．In 1961 | D．In 2000 |
A. The “map” of DNA. B. A special language.
C. Small parts of DNA. D. DNA
【小题3】What did the two scientists first discover in 1961 ?
A. The “map” of DNA. B. A new illness.
C. The language of DNA. D. A message of DNA.
【小题4】What can we do if we understand some “ words” of the language inside the body
| A．Make people get new jobs. |
| B．Make medicine for illnesses. |
| C．Make maps of human. |
| D．Make people less attractive. |
| A．It can cause good or bad results. |
| B．It can cause only good results. |
| C．It can cause good results but won’t work. |
| D．It can cause only bad results. |
Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
A person needs at least 1/2 gallon of water daily just for drinking. Store at least1 gallon of water per person per day and be prepared for a 72-hour period. It’s suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, dried milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights and spare batteries.
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks.
Prepare a battery –powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes.
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
【小题1】You should prepare all of the following except _______________.
| A．canned juices |
| B．dried fruits |
| C．fresh vegetables |
| D．dried milk |
| A．some warm clothes and bedding supplies |
| B．some hot water |
| C．some batteries |
| D．some flashlights |
| A．clothes are used to protect your head |
| B．a telephone is the most important prepared thing |
| C．flashlights but not matches are first used after earthquakes |
| D．we need to prepare some supplies only at home |
Food waste has become a big problem in China.
Zhou Jinsong, a canteen(食堂) manager at Central South University, said that students produce over 12 barrels(桶) of leftovers every day — each barrel stands at one meter in height. Zhou’s canteen is just one of several on the campus.
According to Xinhua News Agency, the food wasted by Chinese people equates to about 50 million tons of grain every year, or 10 percent of the country’s total annual grain production. This food could feed another 200 million people. What students waste every year could feed over 10 million people. Students nowadays are well protected by their families and hardly know how hard farmers work to provide them with the food they eat.
“Since the 1980s, when Chinese gradually became richer, food waste has been a subject of debate. But things have hardly changed over the years,” said Yu Changjiang, a sociologist at Peking University. “It’s the Chinese way of showing respect to friends, often referred as Mianzi.”
But rather than tradition, huge public spending on government banquets(宴会) is also causing food waste, said Zhou Xiaozheng from the sociology department at Renmin University of China. “It’s the result of widespread reception meals at government levels. It is also important that everyone thinks about how they can do their best to reduce food waste.”
【小题1】Which of the following statements is not the reasons for food waste?
| A．Students hardly know farmers’ hard work on the farm. |
| B．The government spends a large amount of money on government banquets. |
| C．Leaving some food after a banquet is the Chinese way to show respect to guests. |
| D．The food in the college canteen is not delicious. |
| A．In a newspaper. | B．In a traffic report. |
| C．On a health website. | D．In a story book. |
According to some predictions, human beings will die out in 2012. Nearly all people think it’s impossible, but there are some more earthquakes in recent years.
Animals can predict the weather or other natural events. It may sound strange, but farmers living in the countryside think so. For hundreds of years , they have observed animals.
“Animals ’ behavior can be connected to future weather conditions or events.” They say. For example, if cows lie down, a rainstorm is coming. There are many traditional stories connecting animals and natural events. Many people think that these stories don’t have scientific evidence( 根据 ) at all. Scientists, however, are beginning to take another look at some of these ideas.
A Japanese earthquake researcher named Kiyoshi Shimamura noticed an increase in dog bites a short time before earthquake hit. Then he did research on twelve public health centers in Kobe, Japan. These health centers treated people after the 1995 earthquake . He got some interesting information about the month before the big earthquake: treatment for animals’ bites had increased . In fact, aggressive(侵略的)behavior in dogs, such as biting and barking loudly , jumped 60 percent.
There are also other changes in animals’ behavior before the earthquake. For example, fish began swimming together in large groups , but only in the middle of the water and not near the edges. Birds flew away from their nests for many days, leaving their eggs unprotected . These animals’ behavior suggests that animals may be able to predict natural events better than people.
【小题1】What would cows behave before a rainstorm?
| A．Running | B．Biting | C．Lying down | D．Sleeping |
| A．They leave their homes. | B．They hurt people. |
| C．They lie down in grass. | D．They stay together in large groups. |
| A．Fish | B．Cows | C．Pigs | D．All of the above. |
| A．disappeared | B．increased | C．been the same as before. | D．never changed. |
| A．Natural events and animals’ actions. |
| B．What animals do during earthquakes |
| C．Many earthquakes of Japan. |
| D．Some stories about animals. |
Apple’s logo is one of the most familiar icons(图标) around the world. But what’s the story about the Apple logo? The image of the apple is obvious, because that’s the name of the company. What about the bite? The famous story is that the logo shows respect and honour for Alan Turing. He was the father of computer science. He researched artificial intelligence(人工智能) and unlocked German wartime codes(密码). However，after the war, he was put into prison，because of his beliefs. He could not stand the looking down and chose to bite a poisoned apple to end his life in the prison.
However, Rob Janoff, who designed the famous Apple logo, said, “It’s not the truth, but only a legend(传说, 传奇). The real reason why I designed it with a bite is very simple. I wanted people to get that it was an apple not a cherry (樱桃). When I go to markets to buy apples, I always mistake apples for cherries. It really has nothing to do with the scientist.”
Are you kidding? An apple is much bigger than a cherry. It’s very easy to tell. But if you use an apple to design a logo, some people may mistake it for a cherry.
【小题1】Both the apple and the cherry are almost the same actually in ________.
| A．shape | B．size | C．colour | D．weight |
| A．died in the prison | B．used an apple to design a logo |
| C．was put into prison during the war | D．was the father of a computer company |
| A．To introduce its designer. | B．To tell us a legend about it. |
| C．To try to find the truth of it. | D．To explain its market research. |
