21、Drinking alcohol is a socially acceptable behavior in many parts of the world．Some medical experts say light drinking may even be good for your health, especially for the heart．But they say such health benefits should be compared to the many health risks connected with alcohol use．
Some research suggests that having one to two drinks of alcohol a day may offer some health benefits．Several large studies have shown that this type of moderate(适量的) drinking may lower the risk of heart disease and other diseases．
A study last year suggested that drinking small amounts of red wine may help lower the risk of breast cancer in women．Researchers at Medical Center in California studied 36 women．Each woman drank a glass of red or white wine every day for almost a month．Researchers collected blood samples from the women two times a month to measure their hormone(激素) levels．The next month the women who drank red wine were told to drink white wine instead．The white wine drinkers were told to drink red wine．The researchers found that the women who drank red wine had lower levels of the female hormone than the white wine drinkers．They said red grapes have chemicals that may help to lower the risk of breast cancer．
However, recent studies suggested that even small amounts of alcohol may generally increase the risk of breast cancer in women．They found that women who drink four small glasses of wine a week increase their risk of breast cancer by 15 percent．
Many studies have examined the harmful effects of alcohol use on the body．Alicia Ann Kowalchuk serves as medical director, saying “Healthy use for adults --- that's men under age 65 --- is no more than 4 drinks in a day and no more than 14 drinks in a week．And for women of all ages, it's no more than 7 drinks in a week and no more than 2 drinks in a day．” She says too much alcohol use has been linked to liver diseases, and many other cancers．
【1】How did the researchers carry out their study?
A． By following an example．
B． By listing facts．
C． By collecting information worldwide．
D． By comparing tested objects．
【2】Which of the following is the most beneficial to women with breast cancer?
A． A glass of white wine per day．
B． A glass of red wine per day．
C． Small amounts of alcohol per day．
D． Four small glasses of wine per day．
【3】Which of the following shows the structure of the passage?
【4】What is the best title of this passage?
A． Drinking alcohol is popular in many parts of the world
B． Alcohol drinking can be both good and bad for you
C． Drinking alcohol a day may give your health some benefits．
D． Alcohol drinking may do harm to your health
22、Hundreds of people die at sea every year due to ship and airplane accidents. Emergency teams have little time to rescue those in the water because the probability of finding a person alive fall dramatically after six hours. Beyond tides and challenging weather conditions, unsteady coastal currents often make search and rescue operations extremely difficult.
New insight into coastal flows gained by an international research team led by George Haller, Professor of Nonlinear Dynamics at ETH Zurich, promises to enhance the search and rescue techniques currently in use. Using tools from dynamical systems theory and ocean data, the team has developed an algorithm (算法) to predict where objects and people floating in water will go. “Our work has a clear potential to save lives,” says Mattia Serra, the first author of a study recently published in Nature Communications.
In today’s rescue operations at sea, complicated models of ocean dynamics and weather forecasting are used to predict the path of floating objects. For fast-changing coastal waters, however, such predictions are often inaccurate due to uncertain boundaries and missing data. As a result, a search may be launched in the wrong location, causing a loss of precious time.
Haller’s research team obtained mathematical results predicting that objects floating on the ocean’s surface should gather along a few special curves (曲线) which they call TRansient Attracting Profiles (TRAPs). These curves can’t be seen with our eyes but can be tracked from instant ocean surface current data using recent mathematical methods developed by the ETH team. This enables quick and precise planning of search paths that are less sensitive to uncertainties in the time and place of the accident.
In cooperation with a team from MIT, the ETH team tested their new, TRAP-based search algorithm in two separate ocean experiments near Martha’s Vineyard, which is on the northeastern coast of the United States. Working from the same real-time data available to the Coast Guard, the team successfully identified TRAPs in the region in real time. They found that buoys and manikins (浮标和人体模型) thrown in the water indeed quickly gathered along these emerging curves. “Of several competing approaches tested in this project, this was the only algorithm that consistently found the right location,” says Haller.
“Our results are rapidly obtained, easy to interpret and cheap to perform,” points out Serra. Haller stresses: “Our hope is that this method will become a standard part of the tool kit of coast guards everywhere.”

23、The human societies that have the fewest social divisions are known as hunting and gathering societies. As the name implies, these groups depend on hunting and gathering for their survival. In some, the men hunt animals and the women gather plants. In others, both men and women (and children) gather plants, the men hunt large animals, and both men and women hunt small animals. Beyond this basic division of labor by sex, there are few social divisions. The groups usually have a shaman, an individual thought to be able to influence spiritual forces, but shamans, too, must help obtain food.
In addition to sex, the major unit of organization within the group is the family. Most members of the group are related by shared ancestors or marriage. Because the family is the only social structure in these societies, it performs many functions that in modern societies are divided among different institutions. Thus, the family distributes food to its members, educates its children (especially in food skills), gives medicine to the sick, and so on.
Hunters and gatherers are the most equal of all societies. Because the food that they hunt and gather cannot be preserved or stored, the people cannot accumulate possessions. Thus, no one becomes wealthier than anyone else. There are no rulers, and most decisions are arrived at through discussion. Because their needs are basic and they do not accumulate possessions, hunters and gatherers have the most leisure time of all human groups.
All human groups were once hunters and gatherers, and until several hundred years ago, such societies were common. Their way of life ended when other groups took over the areas on which they depended for their food. Today only a few remain, such as the Pygmies of central Africa, the San of the Namibian desert, and the Aborigines of Australia.

24、In the sport of track and field, athletes compete not only with one another but against themselves, and with each race they try to achieve a new personal best.
For one Nebraska teen running in what would likely be his final cross-country outing before graduating from high school, Brandon Schutt's personal best turned out not to be about marking the fastest time but displaying the biggest heart. A mile into the 3.1-mile race, however, Schutt realized he wasn't going to be able to keep up the necessary drive. Rather than risk injury, he slowed to a comfortable pace that would allow him to simply enjoy the moment and the day.
Meanwhile, as a student in Omaha Burke High School, Blake Cerveny was running a very different kind of race. Aiming to beat his own personal record, after a fast start, he continued to push himself hard. With less than 400 meters to go, Cerveny's legs cramped（抽筋）up and failed him. Determined to finish, Cerveny rose from the ground and continued on, only to fall again after another 150 meters…and again, he got up and started running. This time he'd made it only 25 meters more before going down. But he wasn't done yet. Less than 100 meters from the finish line, he lay curled on the ground. His legs had simply given out.
Before Cerveny's dad could reach his son, another runner—Brandon Schutt—was at his side to offer a helping hand. His first attempt to get Cerveny up failed, but like Cerveny, he refused to quit, too. With a second pull, Cerveny was on his feet.
At a measured jog, with Cerveny holding Schutt for support and Schutt helping Cerveny maintain balance, the two completed the final 75 meters of the course together. Schutt even made sure the injured runner crossed the finish line first, securing his opponent a faster time. Although Cerveny was automatically disqualified for having received help, Schutt's time for the race would stand.
【1】What can we learn about Schutt at the beginning of the running?
A．He was confident to win the first place.
B．He was nervous about the coming graduation.
C．He was clear about his own strengths and weaknesses.
D．He was dissatisfied with the annoying surrounding things.
【2】Why did Cerveny take part in the competition?
A．To break his own running record.
B．To show his difference from others.
C．To be admitted into the national team.
D．To turn his father's dream into reality.
【3】What happened to Cerveny during the running?
A．He helped Schutt finish the race.
B．He had the first fall at 150 meters.
C．He finally finished the race faster than Schutt.
D．He injured his own arms on account of the falls.
【4】What can be the best title for the text?
A．Sportsmanship Is What We Should Respect
B．A Hero Runner Carries A Competitor To The Safe Place
C．Runners Met Again After Crossing The Finish Line Together
D．A Teen Runner Helped A Competitor Finish The Race After He Fell Down

26、Directions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.
The enduring power of print for learning in a digital world
Today's students see themselves as digital natives, the first generation to grow up surrounded by technology like smartphones, tablets and e-readers. We’ve seen students now equipped with school-issued iPads and access to e-textbooks. Given this trend, it might be assumed that students' familiarity and preference for technology translates into better learning outcomes. But more and more studies show that it’s not always the case. So, there are some lessons that can be conveyed to us about print’s place in an increasingly digital world.
We all read for many reasons. Sometimes we're looking for an answer to a very specific question. Other times, we want to browse a newspaper for today’s headlines. As we’re about to pick up an article or text in a printed or digital format, we should keep in mind why we're reading. There’s likely to be a difference in which medium works best for which purpose.
One of the most consistent findings of the studies is that, for some tasks, medium doesn't seem to matter. If all students are being asked to do is to understand and remember the big idea or gist of what they’re reading, there’s no benefit in selecting one medium over another. But when the reading assignment demands more engagement or deeper comprehension, students may be better off reading print. Teachers could make students aware that their ability to comprehend the assignment may be influenced by the medium they choose. This awareness could lessen the difference in students’ judgments of their performance compared with how they actually performed.
In another experiment, researchers were able to create meaningful records of college students based on the way they read and comprehended from printed and digital texts. Among those records, it was found that a select group of undergraduates who actually comprehended better when they moved from print to digital. But they actually read slower when the text was on the computer than when it was in a book. Using this select group as a model, students could possibly be taught or directed to fight the tendency to glide through online texts.
