upset all the time can result in premature graying.here is a closer look at this situation and why some believe that this old wives tale could be true.as one ages，the hairs on the head also age.in fact，just about everything on the human body begins to show signs of wear and tear after a while.the joints wear and become stiff and skin wears and becomes wrinkled.hairs on the head grow and eventually die.they are replaced，but in the process something else happens.when new hairs are replaced，the color or pigment (色素) is also added to them.however，as one ages，this pigment becomes less and less available.at first，hairs will have a limited amount of pigment and they will appear to be grayish in color.in time，they will lose all of their pigment and will be white.many things are known to cause graying，and genetics is a very powerful factor.if one of your parents turns gray at an early age，there is a good chance that you will too.some people begin the graying process in high school，while others may be over the age of forty.constant worry and tension can have many harmful effects on the human body.it is a known fact that stressful times can cause one to suffer hair loss.it would make sense that if it can cause these problems，perhaps it also may contribute to graying.however，there is no sound evidence to support this.on the other hand，many medical professionals believe that there may be a link between graying and a constant state of anxiety or tension.does stress cause gray hair？there is no scientific evidence to support the theory，but it is best to avoid stressful situations.【语篇解读】压力会导致头发变白吗？许多人相信情况是这样的。本文从年龄和基因两方面谈了头发变白的原因，持续的压力和忧虑对于身体是有害的，可导致脱发。但是，究竟压力和头发变白之间是否有联系，目前尚无定论。1the underlined phrase in the first paragraph most probably means_.aclever remarksbsilly

jarvik-7 artificial heart was being cheered as the model of human creativeness. the sight of barney clarkalive and conscious after trading his diseased heart for a metal-and-plastic pumpconvinced the press, the public and many doctors that the future had arrived. it hadnt. after monitoring production of the jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the u.s. food and drug administration concluded that the machine was doing more to endanger lives than to save them. last week the agency cancelled its earlier approval, effectively banning (禁止) the device.the recall may hurt symbion inc., maker of the jarvik-7, but it wont end the request for an artificial heart. one problem with the banned mode is that the tubes connecting it to an external power source created a passage for infection. inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patients chest. the first sample products arent expected for another 10 or 20 years. but some people are already worrying that theyll work-and that americas overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. if such expenditures (开支) cut into funding for more basic care, the net effect could actually be a decline in the nations health.11. according to the passage, the jarvik-7 artificial heart proved to be _.a. a technical failure b. a technical wonder c. a good life-saver d. an effective means to treat heart disease12. from the passage we know that symbion inc. _.a. has been banned by the government from producing artificial heartsb. will review the effects of artificial hearts before designing new modelsc. may continue to work on new models of reliable artificial heartsd. can make new models of artificial hearts available on the market in 10 to 20 years13. the new models of artificial hearts are expected _.a. to have a working life of 10 or 20 years b. to be set fully in the patients chestc. to be equipped with an external power source d. to create a new passage for infection14. the word them in line 7, para. 2 refers to _.a. doctors who treat heart diseases b. makers of artificial heartsc. americas health-care programs d. new models of artificial hearts15. some people feel that _.a.
