A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people．Puppy love（早恋）may bring stress for young people and can lead to depression (沮丧，抑郁）. The study shows that girls become more depressed than boys, and younger girls are the worst of all．

The possible reason for the connection between love and higher risk of depression for girls is “loss of self”．According to the study，even though boys would say “lose themselves in a romantic relationship”，this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions．They won’t tell that to their parents．

Dr Marianm Kaufman，an expert on young people problems，says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression．She advises kids not to jump into romance too early. During growing up，it is important for young people to build strong friendships and a strong sense of self．She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family．

Parents should watch for signs of depression—eating or mood changes—and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age．Love will always make us feel young，but only maturity （成熟） gives us a chance to avoid its bad side effects．

Crossing your legs is an extremely common habit; most people don't even notice that they're doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.

A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You won't feel any immediate effects, but repeated, drawn-out increases in blood pressure can cause long-term health issues. So, planning to sit for a long period of time? Don't keep your legs crossed.

Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg, explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.

So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

1.What can we learn about crossing one's legs?

A. It is a very bad social habit.

B. It is usually practiced deliberately.

C. It can make others feel uncomfortable.

D. It can do harm to people's health.

2.According to the study, sitting with your legs crossed can______.

A. resist gravity effectively B. affect your blood pressure

C. lead to heart attacks easily D. improve the function of legs

3.In the third paragraph "pins and needles" probably means______.

A. serious muscle injuries B. being a little nervous

C. slight sharp pains D. being highly flexible

4.What is the main purpose of the text?

A. To give readers some advice. B. To compare common habits.

C. To evaluate effects of an experiment. D. To introduce research methods.

【题目】We discuss the issue of when to help a patient die. Doctors of our generation are not newcomers to this question. Going back to my internship(实习)days, I can remember many patients in pain, sometimes in coma(昏迷), with late, hopeless cancer. For many of them, we wrote an order for heavy medication—morphine(吗啡)by the clock. This was not talked about openly and little was written about it. It was essential, not controversial.

The best way to bring the problem into focus is to describe two patients whom I cared for. The first, formerly a nurse, had an automobile accident. A few days later her lungs seemed to fill up; her heart developed dangerous rhythm disturbances. So there she was: in coma, on a breathing machine, her heartbeat maintained with an electrical device. One day after rounds, my secretary said the husband and son of the patient wanted to see me. They told me their wife and mother was obviously going to die; she was a nurse and had told her family that she never wanted this kind of terrible death, being maintained by machines. I told them that while I respected their view, there was nothing deadly about her situation. The kidney(肾) failure she had was just the kind for which the artificial kidney was most effective. While possibly a bit reassured, they were disappointed. Here was the head surgeon seemingly determined to keep everybody alive, no matter what.

Within a few days the patient's pacemaker(起搏器) could be removed and she awoke from her coma. About six months later, the door of my office opened and in walked a gloriously fit woman. After some cheery words of appreciation, the father and son asked to speak to me alone. As soon as the door closed, both men became quite tearful. All that came out was, “We want you to know how wrong we were.”

The second patient was an 85-year-old lady whose hair caught fire while she was smoking. She arrived with a deep burn; I knew it would surely be deadly. As a remarkable coincidence there was a meeting for discussion going on at the time in medical ethics(道德). The speaker asked me if I had any sort of ethical problem I could bring up for discussion. I described the case and asked the students their opinion. After the discussion, I made a remark that was, when looking back, a serious mistake. I said, "I'll take the word back to the nurses about her and we will talk about it some more before we decide." The instructor and the students were shocked: "You mean this is a real patient?" The teacher of ethics was not accustomed to being challenged by actuality. In any event, I went back and met with the nurses. A day or two later, when she was making no progress and was suffering terribly, we began to back off treatment. Soon she died quietly and not in pain. As a reasonable physician, you had better move ahead and do what you would want done for you. And don't discuss it with the world first. There is a lesson here for everybody. Assisting people to leave this life requires strong judgment and long experience to avoid its misuse.

【题目】When Johnson called again, the manager received him very politely. “That is a most remarkable oil you brought us, Mr Johnson,” he said. Johnson nodded his smooth, dark head. That was something he knew very well. “I’ve never seen anything like it,” the manager admitted. Johnson nodded again. “No?” he said politely. Then he added, “But I think you will, sir. A very great deal of it.” He appeared to think for a moment. “I think you will find it will be on sale seven, perhaps, eight years from now.” He smiled.

The manager thought that was uncertain. He said, “It is better than our fish oils. I admit that.” “So I am told, sir,” agreed Johnson.

“Have you any plans to produce it yourself, Mr Johnson?”

Johnson smiled again. “Would I be showing it to you if I had?”

“We might add some chemicals to one of our own fish oils,” said the manager.

“It would be expensive to do that, even if you could.” Johnson said gently. “Besides,” he added, “I am told that this oil will be much cheaper than your best fish oils. Cheaper than any vegetable oil, in fact.”

“Perhaps,” said the manager. “Well, I suppose you want to make an arrangement, Mr Johnson, Shall we discuss it?”

“Of course,” said Johnson. “There are two ways of dealing with a situation of this sort. The usual one is to prevent it altogether or at least to delay it as long as possible. That is, of course, the best way,” The manager nodded. He knew plenty about all that.

“But I am so sorry for you, because, you see, that is not possible this time.” The manager had his doubts, but all he said was an inquiring(asking), “Oh?”

“The other way,” continued Johnson, “is to produce yourself before the trouble starts.”

【1】The manager thought of adding chemicals to the fish oil to make it ________.

A. cheaper than the new oil B. more quickly
