听力原文： More than 50 percent of all homes in the U.S. have one thing in common; people living in them keep one or two small animals as pets. In fact there are more pets in the U.S than children. Why？
Researchers have been attempting to find the scientific answer to this question. Much has been written about how animals, violent crimes, and about how they help children deal with emotional problems.
Last year researchers met at the America's National Institute of Health. They found there is a lot of evidence that animals may be helpful to human health. But they agreed more work is needed to show and measure these facts in a scientific way.
Recent studies have confirmed an animal coming effect. For example, a research at a government laboratory near Washington examined how animals influence blood pressure and heart rote. The study involves 92 students. All were in good health. Each one met with a dog whom they did not know but who was friendly. The students were permitted to touch or hold the dog. The researchers measured the students' blood pressure and heart ram before and during the meeting. The results showed an overall drop in blood pressure and heart rate after the students talked to the dog. The researcher said the same effect often takes place in the animal itself..
Other students have shown that different people react differently to animals. The good effects of pets on physical and mental health may be linked to a person's position within a social; or economic group.
Researchers say they still do not fully understand the physical changes that take place when humans and animals are together, but they say it is clear that animals fill a human need. Animal pets don't reject people because they are sick or disabled. As a result, they may provide the sick or the disabled with a better sense of security.
(30)
A．That more work is necessary for those facts.
B．That animals are helpless to healthy people.
C．That animals can also become friends of humans.
D．That they had a very successful discovery.
Passage 3
Electronic cigarettes are handheld nicotine-delivery devices that, despite, a devoted following, are currently swirling in controversy. New York is pushing to become the first state to ban the devices, which so far remain _1_ and mostly unstudied. With cute colors, fruity flavors clever designs and other options, e-cigarettes may hold too much _2_ for young people, critics warn, offering an easy gateway to nicotine addiction. But those criticisms clash with _3_ strong arguments for the value of e-cigarettes. The devices, which are tobacco-free, may be a safer _4_ to cigarettes, say advocates, who point to thousands of smoker who say they have used e-cigarettes to help them quit Electronic cigarettes _5_ use a rechargeable battery-operated heating element to vaporize the nicotine in a replaceable pipe. Nicotine is the substance in tobacco that people can become addicted to. Some cigarettes are made to look like real cigarettes, cigars or pipes. Others look like pens or USB memory devices. No tobacco is _6_ in e-cigarettes and there is no smoke either. Instead, as users breathe in, they take in nicotine-filled vapor. By isolating nicotine, e-cigarettes should carry far fewer chemical risks than _7_ cigarettes. Tobacco contains about 5,000 _8_ chemicals with as many as 100,000 more that haven’t yet been known. E-cigarettes _9_ many of those ingredients. Researchers also found evidence that e-cigarettes reduce desires among smokers, not just for nicotine but also for the need to hold something in their hands and put something in their mouths. As a cigarette-quitting strategy, it’s not that the devices are good for anyone, but they are just better than what they’re meant to _10_.

D) opaque
E)involved
F)typically
G)solely

第1空答案是：
Salovey tells of a simple test. Some four-year-old kids were invited into a room and were given the following instruction: " You can have this marshmallow right now; or if you wait, you can have two marshmallows when I get back. " Then, the researcher left. Some kids grabbed for the treat as soon as the researcher was out the door, while others waited for the researcher to return. By the time the kids reached high school, significant differences appeared between the two groups. The kids who held out for two marshmallows were better adjusted, more popular, more adventurous, more confident, and more dependable than kids in the quick gratification group. The latter group was also more likely to be lonely, more easily frustrated, more stubborn, more likely to buckle under stress, and more likely to shy away from challenges. When both groups took scholastic aptitude tests, the "hold out group" walloped the "quick gratification group" by 210 points (the test scores range from a minimum of 200 points to a maximum of 800, with an average for all students of 500 points).
Researchers have been discussing whether it' s possible to raise a person' s IQ. Geneticists say No, while social scientists say Yes. But while brain power researchers continue the debate, social science researchers have concluded that it's possible to improve a person' s EQ, and in particular, a person' s "people skills, " such as empathy, graciousness, and the ability to "read" a social situation.
According to the social scientists, there is little doubt that people without sufficient EQ will have a hard time surviving in life. EQ is perhaps best observed in people described as either pessimists or optimists. Optimistic people have high EQ and treat obstacles as minor, while the pessimistic people have low-EQ and personalizes all setbacks. In social research circles, EQ denotes one' s ability to survive, and it' s here that there may be an overlap between EQ, IQ, genetics and environment. As to that, I am reminded of the words of Darwin, "The biggest, the smartest, and the strongest are not the survivors. Rather, the survivors are the most adaptable. " Those of us who survive and thrive in this complex world are not only the most adaptable, but also the most optimistic and the most likely to have a high EQ.
EQ gets you promoted, not because________.
A．a person with high EQ is better adjusted
B．a person with high EQ is more stubborn
C．a person with high EQ is more confident
D．A person with high EQ is more popular

The human body may look solid, but most of it is water. New-born babies are as much as eighty-five percent water. Women are about sixty five percent water, and men about seventy-five percent. Women usually have less water than men because women, in general, have more fat cells. Fat cells hold less water than other kinds of cells.
Water is necessary for cooling the body on hot days, and when we are working hard or exercising. Water carries body heat to the surface of the skin when the heat is lost through perspiration.
Researchers note that fat cells block body heat from escaping quickly. Fat cells under the skin act like warm clothing to keep body heat inside. This is why over-weight people have a more difficult time staying cool than thin people.
Researchers also note that cold liquids cool us faster than warm liquids. This is because cold liquids take up more heat inside the body and carry it away faster. They say, however, that cold sweet drinks do not work well. The sugar slows the liquid from getting into the bloodstream.
The body loses water every day through perspiration and urine. If we lose too much, we will become sick. To replace what is lost, health experts say grown persons should drink about two liters of liquids each day, and more in hot weather. They say we also can get some of the water we need in the foods we eat. Most fruits and vegetables have more than eighty percent water. Even bread has about thirty-three percent water.
From the passage we learn that among the following four groups of people _______.
A．fat women are over eighty percent water
B．thin men are never eighty percent water
C．new-born infants are over eighty percent water
D．elderly adults are over eighty percent water
