6.In March 2012,researchers in the United States announce that they have developed the first wirelessly controlled device that can supply a drug directly into the body.A small chip is implanted under the skin.It contains the medicine,which it releases at preset(预先设定的)times.
The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses.
A company called MicroCHIPS began developing the device about fifteen years ago.Last month,the company released the results of its first successful tests in humans.The tests took place in Denmark with seven women with osteoporosis.
Osteoporosis causes bones to become weak and break easily.The disorder is common among older people,especially women.Many patients have to give themselves daily injections of medicine.One type of treatment requires injections for two years.
Robert farra is the president of MicroCHIPS.He says many patients stop taking the medicine because of the pain and stress of the injections and that only twenty-five percent of the patients will go through the entire twenty-four months of treatment.
The microchip is a few centimeters long.It has small sections that each hold a single dose(剂量)of medicine.Mr.Farra says the device has to be programmed with the times to release the drug and that doctors will be able to reprogram the device from a computer or even a cell phone.
The seven women in the study were aged sixty-five to seventy.The researchers say the implants were just as effective as daily injections.And they say the dosage amounts were more exact than patients often give themselves.
The microchips in the study held only twenty doses of medicine.Mr.Farra and his team are now designing a version that could hold a full year's worth of medicine.
Robert Farra says,"The new version may take us two years,and then we may be required to do two additional trials,taking about four years before the device is available on the commercial scale."
71.Which of the following about the new device is right?D
A.It is of great use to all patients.
B.It is the first Microchip in the world.
C.It can cure long-term illnesses completely.
D.It can release medicine regularly as preset.
72.According to Paragraph 4,we knowB.
A.osteoporosis is believed to be a deadly disease
B.patients who suffer osteoporosis may easily break their bones
C.whoever suffers osteoporosis has to get daily injections
D.the only treatment of osteoporosis is injections for at least two years
73.Which of the following is TRUE?D
A.The seven women participants all got over the disease after the test.
B.The company MicroCHIPS began developing the device in about 1998.
C.the test with the women took seven years.
D.It may be six years before the device is put to commercial use.
74.Which is NOT the advantage of the device?C
A.It can release exact amount of medicine.
B.It can free patients the pain and stress of injections.
C.it held only twenty doses of medicine.
D.It is as effective as daily injections.
75.Which may be the best title of the passage?A
A.Taking medicine with a microchip under the skin
B.A successful test with seven women
C.Microchips are very useful
D.A new treatment of osteoporosis.
分析 文章介绍了一项发明是用芯片将药物注入到患者的皮肤下.可以定期的给病人一些剂量的药物,这项发明会改变很多人的生活.
解答 71.D.细节理解题.根据文章第一段"A small chip is implanted under the skin.It contains the medicine,which it releases at preset(预先设定的)times"可知新设备是用芯片将药物注入到患者的皮肤下.可以定期的给病人一些剂量的药物;故选D.
72.B.细节理解题.根据文章第四段"Osteoporosis causes bones to become weak and break easily"可知患有骨质疏松症的患者可能会折断他们的骨头;故选B.
73.D.推理判断题.根据文章最后一段"The new version may take us two years,and then we may be required to do two additional trials,taking about four years before the device is available on the commercial scale"可知新产品投入使用还需要六年时间;故选D.
74.C.细节理解题.根据倒数第二段"The microchips in the study held only twenty doses of medicine.Mr.Farra and his team are now designing a version that could hold a full year's worth of medicine"可知心设备的缺点是只可以使用而是计量;故选C.
75.A.主旨大意题:从文章第一段的句子:Researchers in the United States have developed the first wirelessly controlled device that can supply a drug directly into the body.A small chip is implanted (植入) under the skin.可知这项发明是用芯片将药物注入到患者的皮肤下.故选A.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
