There are many social science majors in large companies who fill important positions. For example, a number of research studies found that social science majors had achieved greater managerial success than those who had technical training or pre-professional courses. Studies show that social science majors are most suited for change, which is the leading feature (特点) of the kind of high speed, high-pressure, high-toch world we now live in.
Social science majors are not only experiencing success in their long-term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry-level positions with social science graduates. The study also showed that the most sought-after quality in a person who was looking for a job was communication skills, noted as "very important" by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.
Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don't regret their choice of study.
By saying that "you may have had the last laugh" in the first paragraph, the author means that you may have______.
A．shared the jokes with computer majors
B．earned as much as computer majors
C．found jobs more easily than computer majors
D．stopped joking about computer majors

听力原文： Generations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told, and told again, is as necessary as putting gasoline in the family car before starting a trip.
But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the number of people who didn't have breakfast increased foam 8.8 million to 11.7 million. For those who feel pain of guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect performance," said Arnold E. Bender, former professor of nutrition at Queen Elizabeth Collage in London, "nor does giving people breakfast improve performance."
Scientific evidence linking breakfast to better health or better performance is surprisingly indicated, and most of the recent wonk involves children, not adults.
(30)
A．Several studies have been done in the past few years.
B．The omission of breakfast does no harm to one' s health.
C．Adults have especially made studies in this field.
D．Eating little in the morning is good for health.

A recent review of 17 studies from 17 nations reveals that people who eat the most fruits and vegetables have about half the cancer raters of those who eat the least. In fact, some research suggests that frequent consumption of fruits and vegetables can cut the risk of lung cancer even in smokers.
One of the most studied antioxidants in vegetables and fruits thought to protect against cancer is beta-carotene(β胡萝卜素), concentrated in deep green, yellow and orange vegetables such as carrots, sweet potatoes and spinach.
Research also shows that beta-carotene can change in the body to retinoic acid (维生素A酸), a substance used in clinical trials to treat certain cancers.
Here are some of the foods that contain cancer-fighting chemicals.
Tomatoes. One of the compounds in tomatoes that is thought to reduce the risk of cancer is lycopene(蕃茄素), the pigment (色素) that makes tomatoes red. Lycopene, an antioxidant that is also found in watermelons and apricots, quenches certain cancer-triggering oxygen free fadicals. Healthy people with the most blood lycopene.
Green Vegetables. A recent Italian study showed that dark-green leafy vegetables lower the risk of many cancer. Spinach, broccoli, kale and dark-green lettuces are chock-full of antioxidants, including beta-carotene, folate(叶酸) and lutein(叶黄素).A good rule of thumb(单凭经验的做法) : the darker the vegetable, the more antioxidants within.
Pungent preventives(刺激性的预防物). A whole host of chemicals thought to have cancer-inhibiting properties have been identified in allium vegetables, which include garlic, onions and scallions(大葱). Animal studies show that many of these chemicals block carcinogens that have been linked to colon, stomach, lung and liver cancer. A study at Pennsylvania State University found that feeding rats various garlic extracts and preparations(配制好的食物) reduced mammary tumors by as much as 71 percent. In humans, studies suggest that those who eat more onions and garlic are less prone to gastrointestinal cancer.
Research suggests that garlic compounds may even interfere with cancer progression. A recent German study found that ajoene, a garlic compound, is toxic to malignant cells. Garlic may also antagonize existing cancer by boosting(促进) immune functions, according to researchers at Loma Linda University School of Medicine. Their study, done on mice, found that garlic's sulfur compounds increased the activity of macrophages and T-lymphocytes(淋巴细胞), two of the components of the immune system that destroy tumor ceils.
Recent research indicated that what people eat may help to significantly reduce their risk of developing cancer.
A．Right
B．Wrong
C．Not mentioned
