The summer is so hot and sticky, why would we want to sweat even more by exercising? Or is it just I who think like that? Sweat and clothes sticking to our bodies as we move make exercise seem rather uncomfortable. What can be done to fix it?
Researchers at MIT have come up with a solution. They’ve developed a workout suit with flaps that open as the wearer begins sweating. As the person cools off, the flaps shrink until they assume their original position.
Sounds cool, sounds practical. These flaps are lined with live, microbial ( 微生物的)cells. These cells can detect when the body is heating up too much, and in response, expand. It’s just as if they were working within any other organism, recognizing patterns of heating and cooling, then responding appropriately to maintain body temperature. It seems kind of strange to have living cells (that aren’t your own) on you, right? Not to fear, these cells have been believed safe. Plus, there’s a material in the suit that helps the flaps/cells hover ever so slightly above the exerciser's skin. The flaps start opening as soon as people start feeling warm and sweaty, and the bit of space between the suit and the skin helps develop that feeling of cool and refreshing air as they move.

According to Gadgetify.com, researchers have also been working to apply this technology to running shoes as well. Moisture-responsive workout clothing has the potential to revolutionize sport fashion industry. People can stay drier, cooler and fresher at the end of the workout, which sounds better than leaving the gym with a trail of sweat and a red face. It’s possible that the comfort of these suits can make people enjoy exercising more and exercise with more intensity.

When it comes to medical care, many patients and doctors believe "more is better." But what they do not realize is that overtreatment-too many scans, too many blood tests, too many procedures-may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.
Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system(免疫系统), they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X-rays, and repeatedly referred her to experts for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she caught a cold. She had as many as 25 doctor visits during one six-month period. The couple was spending about $30,000 a year for her care.
After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. "It's a really hard thing to determine when doctors have crossed the line," Mr. Power said. "You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose?" Mr. Power then spoke with his own primary care doctor, who advised him to find a new expert to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition was stable. Now she sees the doctor only four or five times a year.
1.Which of the following was a problem for Mrs. Power during her medical treatment?
A.She had to be hospitalized for three weeks whenever she had a cold.
B.Her doctor asked her to consult other experts for her complaints.
C.When test results showed she was fine, her doctor still ordered more tests.
D.She did not have any insurance, so she became penniless.
2.When did the Powers start to doubt the treatment of Mrs. Power?
A.After they knew about the treatment of other patients.
B.After they analyzed the results of her blood tests
C.After Mrs power was cured of her illness.
D.After the new expert tested her.
3.Which of the following can replace the underlined word "stable" in the last paragraph?
A.not getting worse B.improper
C.unchangeable D.uncertain
4.What is the main idea of this passage?
A.Treatments do not always cause harmful side effects.
B.Patients tend to believe more testing is better treatment.
C.Doctors generally recommend office visits that are necessary.
D.Too much medical care may not be beneficial to patients.
