Perhaps everyone has heard warnings about the “freshman 15”, but is it true that many college students weigh 15 pounds more during their first year at school?
Recent studies find that some first-year students are indeed likely to gain weight, but it might not be the full freshman 15, and it may not all happen during the freshman year. That might sound like good news, but it’s not. Doctors are concerned that students who gradually put on pounds could have healthy problems.
Studies show that students on average gain 3-10 pounds during their first 2 years of college. Most of this weight gain occurs during the first year. A college offers many temptations (诱惑). You’re on your own and free to eat what you want. In addition, you may not get as much exercise as you did in high school. A college is also a time of change, and people sometimes eat in response to (对……做出反应) homesickness, sadness, or stress, and all of these can be part of starting a new life in college.
Some weight gain is normal as a young body grows, but rapid weight gain may become a problem. Weight gain that pushes you above the body’s normal range carries health risks. People who are overweight are more likely to have high blood pressure, heart disease and develop certain cancers.
The best way to beat “freshman 15” is to prevent it altogether. Good habits like a balanced diet, regular exercise, and getting enough sleep can do more than keeping the pounds off. They can also help you stay healthy.

These days no car show is complete without an electric car, and the 2011 North American International Auto Show in Detroit, US, which ran from January 10 to 23, was no exception.
Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV. BMW and Volvo also had prominent displays at the show, proving that they can produce practical, yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries, improved performance and greater consumer acceptance could make 2011 the “year of el
ectric car”.
It’s long been clear that electric cars score heavily for convenience. They are, for instance, much easier to maintain than gasoline-powered cars. When the battery runs out, you simply replace it or recharge it, just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline. Better yet, electric cars don’t emit exhaust fumes. As a result, they don’t produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly. So, what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users. However, it is also a potential obstacle. For a start, installing charging stations in owners’ homes will be a challenge, particularly for those who have to park several blocks away from their homes.
Also, charging the car’s battery still takes quite a long time. It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50 miles (80 km) or less between charges. In cases where a driver wishes to charge the car primarily at home (perhaps overnight), this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular. A hybrid car has more than one energy source, usually a traditional gasoline fuel tank and an electric battery. It’s like a more practical version of an electric car: It’s greener than a conventional vehicle, with fewer CO2 emissions, yet it also doubles as a conventional vehicle.
“I would say that hybrid is a transition to fully electronic,” Road and Track magazine editor Richard Horman told Detroit News during the show. “The trend is for lighter, smarter, more economical cars. Of course
, electronic vehicles are meant to be that way.”
This sounds promising, particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However, it seems that the technology associated with electric cars is not yet able to fully meet people’s expectations. Don’t expect gasoline-powered cars to disappear from roads just yet. What made electric cars more convenient?
| A．Easier maintenance. | B．High scores on the show. |
| C．Practicality and large space. | D．Much lower prices. |
Which of the following could NOT act as a potential obstacle of electric cars?
| A．It is rough work to install charging stations at home. |
| B．It is time-consuming to charge the batteries. |
| C．The ranges between charges are limited. |
| D．There’s no need to fill the tank with petrol. |
In Paragraph 10, the underlined word “hybrid” is probably closest in meaning to ________.
| A．gasoline | B．electric | C．combined | D．separated |
The writer’s purpose in writing this passage is to_________.
| A．introduce the 2011 Auto Show in US | B．get readers informed of electric cars |
| C．comment on different types of cars | D．advertise for electric cars |
Temperature is measured by means of a thermometer (温度计). One general form of thermometer depends upon the fact that most solids and liquids expand as their temperature rises. There are one or two exceptions. There is, for instance, a kind of steel called invar (from “invariable”) which does not change its dimensions as temperature changes; it is valuable for making pendulums (钟摆), since, if the length of a pendulum changes, its time of vibration changes. It is also used for making very accurate measuring scales. In both cases, then, changes of atmospheric temperature have no effect if invar is used.
Another exception is that very odd liquid, water, which has many strange properties (特性). As water gets colder it contracts (收缩), which is ordinary behavior, until it reaches the temperature of 30℃. above freezing point. After that, as it gets colder, it expands. This is fortunate---for considering the freezing of a pond. As the water on top gets colder, it shrinks; and so, volume for volume, it becomes heavier and sinks. This goes on until all the pond is at 30℃, but after that, as the water becomes colder it expands. Therefore the colder water stays on top and freezes, covering the pond with ice. If the water went on contracting down to the freezing point, the pond would become a solid block of ice in the end. This would not worry people who live in hot climates, but it would be very serious for those who live in cold climates, especially for those who want to break the ice and catch fish which live in the cold water beneath. Invar is valuable for making pendulums because _______.
| A．it can hardly change its shape or size as temperature changes. |
| B．it will change its dimensions without the change of temperature. |
| C．its time of vibration doesn’t change if its length changes. |
| D．its time of vibration does not change if its length changes. |
As water gets colder after reaching the temperature of 30℃. it will _______.
| A．contract | B．shrink | C．expand | D．freeze |
Which of the following statements is true, according to this passage?
| A．Only invar can be used to make a thermometer. |
| B．Only water can be used to make a thermometer. |
| C．Both invar and water can be used to make a thermometer. |
| D．Neither invar nor water can be used to make a thermometer. |
The best title of this passage is most likely to be _____.
| A．Temperature Measurement | B．Two Exceptions |
| C．Uses of Invar | D．Properties of Water |
There is a boy called Bill in my gym class who has unbearably yellow teeth that almost make everyone feel unpleasant. Recently another boy told Bill that he should “go Ajax” his teeth. Bill was crushed. If the other boy had been thinking, he would have realized that there is a better way to handle such a situation. He could have dealt with it with tact. He could have showed this hurtful truth in a more careful, sensitive way—that’s “tact”.
If a person isn’t sensitive to another’s feelings, there is no way he or she can be tactful. Yesterday, my 5-year-old brother proudly announced that he had cleaned the screen on our television set. Unfortunately, he used furniture polish, which produced an oily film on the television screen. My mother smiled arid thanked him for his efforts—and then showed how to clean the screen properly. Her sensitivity enables my brother to keep his self-respect. Yet, sensitivity alone does not make tact.
“Tactfulness” also requires “truthfulness”. Doctors, for example must be truthful. If a patient has just been disabled in an accident, a tactful doctor will tell the truth—but express it with sensitivity. The doctor may try to give the patient hope by telling them curing techniques under study or about advanced equipment now available. Doctors must use tact with patients’ relatives as well. Instead of bluntly saying, “Your husband is disabled,” a doctor might say, “I’m sorry, but your husband has lost feeling in his legs and. . .”
Tact should not be confused with trickery. Trickery occurs when a nurse is 
about to give a patient an injection（注射） and says, “This won’t hurt a bit. ” Instead of trickery, the nurse might guarantee the patient that the discomfort of the injection is a small thing compared to the benefits of it. It would also be thoughtful for the nurse to tell the patients about some of these benefits.
Tact is a wonderful skill to have, and tactful people are usually admired and respected. Without tact our society would become an intole
rable place to live in. .
The underlined word “crushed” in the first paragraph probably means .
| A．surprised | B．cheated | C．regretful | D．painful |
.
According to the author, his mother’s praise for the brother is .
| A．sensitive and tactful | B．sensitive but not tactful enough |
| C．truthful but not tactful enough | D．sensitive but trickish |
.
Which of the following shows the structure of the passage?

Many Americans take their summer vacations in August. President Obama and his family are among them. This August the first family visited the Florida Gulf Coast. The president wants to promote tourism in the area after the BP oil spill (漏油). The first family took a ten-day vacation on Martha’s Vineyard, an island off the coast of Massachusetts.
Martha’s Vineyard is known for the sailing, sunsets and its tall cliffs overlooking the Atlantic Ocean. The island is about 13 kilometers off the coast and is less than 260 square kilometers. Homes designed like those of earlier times line the streets of Edgartown, Oak Bluffs and Vineyard Haven. These are the major towns on Martha’s Vineyard.
For most of the year, the population of Martha’s Vineyard is about 15 000. In summer, more than 100 000 people crowd the island. In addition to the Obamas, you might see some Hollywood stars and other rich and famous people. Many visitors return year after year.
During warm weather the Vineyard is a good place for many different activities. People can play golf or catch fish. They can rid
e in sailboats or motor boats. They can waterski and swim. They can take quiet walks along sandy beaches and among the thick green trees.
One of the popular places for families with children is the Flying Horses Carousel in Oak Bluffs. It is the oldest continually operated merry-go-round ride in the United States. The colorful wood horses that turn in a circle were created in 1876. One of the best places for children to swim is the Joseph A. Sylvia state beach. The water there is warmer and calmer. Families also enjoy the Felix Neck Wildlife Sanctuary where they can observe much of the island wildlife.
Visitors watch the sunsets sitting on the beach and on rocks in the fishing village of Menemsha. As the sun goes down in the sky it paints yellow, red, and other colors on the clouds. Fishing boats rise and fall with the waves. Bells sound to help guide the boats to land as darkness covers the water.
Historians say British mapmaker Bartholomew Gosnold first made a map of the island for the rulers of England in 1602. Gosnold named the island to honor his baby daughter, Martha. The Vineyard part of the name came from the many wild grape vines Gosnold found on the island. Later, King Charles of England gave the island to businessman Thomas Mayhew of the Massachusetts Bay Colony, whose son established the first European settlement on the island in 1642. By the middle of the nineteenth century, ships from the 
American mainland began bringing visitors to the island. Big hotels were built near the edge of the water. Martha’s Vineyard was on its way to becoming the visitors center that it is today. .
