Of all the animals in the animal kingdom, which one (aside from man) is the cleverest?
There are several ways of measuring the intelligence of animals. In one test a scientist sets three same cans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails.
This is called a delayed-response test. The idea is to find out how long an animal’s memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants have the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remember for nine hours.
To settle the matter, the scientists designed a huge maze (迷宫) and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants’ slower rate of speed, the test shows that chimpanzees are the cleverest animals.
From this and other tests, the scientists drew the following conclusion: an animal’s intelligence depends on the size of its brain in proportion (比例) to the size of its body. The elephant’s brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. A chimp’s brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ!Which is the best title?

[1] Teens need independence, but how do you make sure they are safe? It’s tough to decide when to give your teen more freedom. One parent’s decision for his or her teen may not be right for other parents and their teens. Although every child is different, there are many experiences common to the teenage years. The most common may be the pull and push between dependence and independence.
[2] Many teens are putting themselves at risk for committing(从事) acts of violence and other crimes. No wonder so many parents are concerned, even frightened; no wonder so many try to control the behavior of their teenage children. So, it is important for parents to make rules for their young children.
[3] However, as children get older, they need to learn to make some of their own decisions and life choices. Teens need the chance to practice good decision-making skills, and to manage new life experiences. Parents need to try their best to support their children.
[4] Respect is a two-way street but it starts with you, which means that you should give your teens the respect that you would like to be given. Give them praise for their knowledge and abilities; pay attention to and listen to them. That means showing confidence in your teens, and being supportive. Parents should believe in your teens; set high standards for them, encourage them, expect them to achieve their goals, and provide consistent（一贯的；始终如一的）love and support —including practical help—so they can achieve the promise that lies within them.
[5] Teens are learning to take care of themselves as they prepare for adulthood. That’s what growing up is all about. Give them and appropriate（适当的） amount of freedom and independence. Encourage and promote responsibility and good decision—offering support and gentle help with difficult decisions. Let your teens know they will be given _________________ as they show increasingly responsible behavior.Who is this passage most probably written for? (no more than 5 words)

Ever since they were first put on the market in the early 1990s, genetically modified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would, is it the best solution?
Despite what it promises, GM technology actually has not increased the production potential of any crop. In fact, studies show that the most widely grown GM crop, GM soybeans, has suffered reduced productivity. For instance, a report that analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “The promise was that you could use less chemicals and boost production. But neither is true,” said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.The author develops the second paragraph mainly .
| A．by classification | B．by comparison |
| C．by example | D．by process |
What does the underlined word “boost” in the third paragraph probably mean?

GM companies promise farmers that they will benefit from ______________.
| A．practicing “green” farming |
| B．use of less chemicals |
| C．fair distribution of their crops |
| D．using more crops for fuel |
Which of the following best describes the attitude of the author towards GM technology?
| A．Optimistic | B．Defensive | C．Disapproving | D．Casual |
More than one in eight U. S. adults finds it hard to stay away from the Internet for several days at a time and about one in eleven tries to hide his or her online habit, according to a study showed on Tuesday.
The study by researchers from the Stanford University School of Medicine in California found one in eight adults admitted they needed to spend less time online, saying this showed "problematic Interact use" is present in a sizable portion (部分)of the population.
The study involved a nationwide telephone survey of 2,581 respondents in the spring and summer of 2004 with researchers then examining the data and preparing the report which appears in the October issue of CNS Spectrums.
The survey found that 68.9 percent of respondents were regular Internet users and 13.7 percent of the users found it hard to stay offline for several days at a time.
It found 12.4 percent often stayed online longer than intended, more than 12 percent said they saw a need to cut back on their Internet use, and 8.7 percent tried to conceal (隐瞒) "non-essential "Internet use from family, friends and employers.
A smaller number, 8.2 percent, said they use the Internet to escape problems or a bad mood, while 5.9 percent felt their relationships suffered because of too much Internet use.
One report published earlier this year said that 5 percent to 10 percent of the population likely will experience Internet addiction (上瘾).
It said signs include a disregard for health or appearance, lack of sleep and reducing physical activities and social communications with others, as well as dry eyes and juries of hands and fingers.From Paragraph 2, it tells us _______.

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1887, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备）to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military’s Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能. Irene Joliot-Curie died from leukemia on March 17, 1956.Why was Irene Curie awarded a Military Medal?
