Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages. What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is. Salt is a chemical compound. It is made of sodium (钠) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work. But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (肾) problems. If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips: *Cut back on high salt foods. Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often. *Choose reduced salt bread and breakfast cereals. Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt. *Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals. 小题1:Many people in China don’t realize they are eating too much salt because ______.A.salty food tasted better than reduced salt food | B.they do not calculate the amount of salt they eat | C.about 3/4 of the salt we eat is already in the food we buy | D.few people experience problems from eating too much salt | 小题2: For a healthier life, the author’s suggestion is to ________.A.cut back on food with less salt | B.eat less heavily salted food | C.eat as much reduced salt bread as is wanted | D.stop eating bread and breakfast cereals | 小题3:What is the purpose of the article?A.To warn people of food containing too much salt. | B.To inform people of the right amount of salt taken each day. | C.To advise people to be careful about the amount of salt they eat. | D.To promote (促进) the right way to make reduced salt food. |

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer (使…快活) me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so does crying. Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to offer support and comfort. Tears also enable us to understand our emotions better; sometimes we don"t even know we"re very sad until we cry. We learn about our emotions through crying, and then we can deal with them. Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don"t fight it. It"s a natural — and healthy — emotional response. 小题1:Why didn"t the author cry when her grandmother died?A.Because her father did not want her to feel too sad. | B.Because she did not love her grandmother. | C.Because she was too shy to cry at that time. | D.The author doesn’t give the explanation. | 小题2: It can be inferred (推断) from the text that ______.A.there are two ways to keep healthy | B.laughing does more good to health than crying | C.crying and laughing play the same roles | D.emotional health has a close relationship to physical health | 小题3: According to the author, which of the following statements is true?A.Crying is the best way to get help from others. | B.Holding back tears may cause some health problems. | C.We will know our deep feelings if we cry. | D.We must cry if we want to reduce pressure. | 小题4:What might be the best title for the text?A.Power of Tears | B.How to Keep Healthy | C.Why We Cry | D.A New Scientific Discovery | 小题5: What might the underlined word “fight” in the last paragraph mean?A.come back | B.pay back | C.hold back | D.give back |

UGG boots have been a winter-weather fashion for several years now, combining function, comfort, warmth and even some style. What many UGG enthusiasts don’t know is that their boots are a breeding ground for bacteria and causes foot problems. Doctors believe the boots, which are particularly popular among young teenage girls, are leading to a rise in the number of people suffering pains in their feet and knees. Dr. Ian Drysdale, head of the British College of Osteopathic Medicine, believes because the foot does not get the proper support on the inside, it will lead to more ankle, knee, hip and back problems. “ These boots are not designed for outside wear. Just because something becomes a trend or fashionable doesn’t mean it’s good or right,” he said. “ The particular problem with this type of footwear is that it is unsupported. It is a slipper. You wouldn’t normally expect to be doing outdoor activities from something that’s indoor. If you decide to wear your pajamas outside all the time, someone will come up and say it’s not a good idea.” Dr. Drysdale explained that the feet issues become a particular problem among young teenage girls, whose bones are “plastic” and developing when they are growing. “ If that structure is developing in an inappropriate way,” he said, “then the ultimate structure will be deformed.” UGG Australia, who makes the designer version of the boots, told The Daily Mirror that their boots are “comfort” rather than “performance” footwear and consumers should be aware of “knockoffs(仿制品)” which lack reinforce heels in their boots. 小题1: Teenage girls prefer to wear UGG boots because of the following except__________.A.design | B.comfort | C.quality | D.warmth | 小题2:According to Dr.Ian Drysdale,____________.A.there is a possibility that bacteria will multiply in UGG boots | B.wearing UGG boots will lead to more ankle and toe problems | C.it’s not a good idea to wear boots like UGG outside all the time. | D.teenage girls’ bones are plastic enough to wear UGG boots | 小题3: The underline word “deformed” is closest in meaning to_______.A.shaped | B.strengthened | C.reformed | D.damaged | 小题4:Which of the following can be the best title for the text?A.Potential Harm of UGG Boots | B.The Popularity of UGG Boots | C.The Unique Design of UGG Boots | D.Benefits of UGG Boots |

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift(轮班)work — being awake at night and sleeping during the day. In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help. Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep. Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance. Develop and follow a sleep routine. It"s best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine. Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful. If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (药物治疗) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed. 小题1:The purpose of the text is to_____ .A.persuade workers to have a good sleep | B.advise night workers to keep healthy | C.encourage workers to do day work | D.help night workers to sleep well | 小题2:What does the author recommend?A.A suitable amount of alcohol to help sleep. | B.A regular life on weekday’s and weekends. | C.A bright room without phones to sleep in. | D.A break for sleeping anytime during the day. | 小题3:On which condition should a person turn to a sleep specialist for help?A.If he suffers from a sleep disorder for the first time. | B.If a good sleep environment is greatly needed for him. | C.If he fails to get quality sleep through his own efforts. | D.If he has the problem of falling asleep in the daytime. | 小题4:We can learn from the text that_____________.A.night workers need a long time to fall asleep | B.constant breaks at work help to improve performance | C.it is difficult to create a good sleep environment | D.night work requires people to adjust their body clocks |

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community. "How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that "the vast majority of people" should give up yoga altogether. It"s simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself. The research in the article isn"t groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison. Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you"re breaking them. If you stick to your comfort zone, you"ll never be able to increase your flexibility. If you push to the point where you"re not only uncomfortable, but in real pain, you"ll likely injure yourself. The reasons that yoga causes "serious injury”, according to the Times story, range from students" physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures. Yoga is called a "practice" for a reason. You don"t have to be perfect. You don"t have to tackle every pose. It doesn"t matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there. We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It"s a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer. 小题1:The underlined word is best replaced by __.A.Injure | B.Benefit | C.Push | D.Shape | 小题2:What does author mainly want to tell us in the 3rd paragraph?A.All physical activities are equally harmful. | B.Yoga causes much less injuries than other physical activities. | C.Similar researches have been done before. | D.Yoga, like any other form of exercise, can hurt people. | 小题3:Which is not mentioned among the reasons for yoga being likely to cause injury? A.Teachers lack the knowledge of students’ limits. | B.Modern lifestyle decreases our flexibility. | C.The body doesn’t tell when you are in real pain. | D.Students themselves might not be in good physical condition. | 小题4:What is the author’s attitude towards practicing yoga?A.It’s a shame not to practice yoga. | B.One should push the limits in order to be perfect. | C.The majority should give up yoga for it may cause harm. | D.One should enjoy the physical and mental benefit that yoga brings. |
