Beth Snoke has watched her mother and both grandmothers battle and survive breast (52) So when she was diagnosed, there was no doubt in her mind (53) she had to do. "I do exactly what the doctors say as far as the medicine that I'm on, as (54) as the vitamins, the diet, and the fitness. And I can't stress enough (55) important that is," says Beth Snoke. But a surprising new study shows that (56) every woman who beats breast cancer is getting that message. In fact, nearly 40% of them say even (57) surviving breast cancer, they haven't made significant changes in the (58) they eat or how much they exercise. "Not all survivors are taking advantage of this teachable moment and making positive health changes in (59) life," says Electra Paskett, PhD, at Ohio State University's Comprehensive Cancer Center. Paskett says diet and exercise have been proven to not only help women feel better during and after treatment, they may (60) play a role in preventing some cancers from coming back (61) growing evidence, some women just aren't listening. "Colon cancer survivors (62) exercise have actually been shown to have improved survival rates. So, yes, it is true that perhaps by making some of these healthy choices we can actually increase their health," says Paskett. As a breast cancer survivor (63) , Paskett knows first hand how much difference diet and exercise can (64) The challenge, she says, is to get more survivors to be more like Beth, during and after treatment. Experts say exercising more and eating a healthier diet can also cut (65) on stress and help women overcome depression.

It is unclear what is behind the phenomenon but it may be that beauty creates confidence. The self-confident may appear to be doing better than they are and will not hesitate about asking for a pay rise. Researcher Jason Fletcher, of Yale University in the U.S., rated the attractiveness of the 4,000 men and women. Just over half were judged average, while 7 percent were felt to be very attractive and 8 percent were judged unattractive or very unattractive. The volunteers also sat an IQ test and reported their salary. It became clear that pay scales were far from fair. For instance, a 14- point increase on the IQ score was associated with a 3 to 6 percent increase in wage. But being of above-average looks increased pay by 5 to 10 percent . For a plain person to be paid the same as a very attractive one , they would have to be 40 percent brighter, the journal Economics Letters reports. Dr Fletcher said:“The results do show that people ’s looks have an impact on their wages and it can be very important.” 6.What is the “plainness penalty ”？ A.To be paid less for being ordinarily-looking B.To be laughed at for being ordinarily-looking C.To be fired for being ordinarily-looking D.To be questioned for being ordinarily-looking How many people were rated as very attractive in Jason Fletcher ’s study？A.About 280 B.About 4,000 C.About 2,000 D.About 320 What ’s the average annual salary of a good-looking person？A.￡2,500 B.￡25,000 C.￡22,500 D.￡27,500 Which of the following best summarizes the main idea of the passage ？A.IQ is less important than appearance B.Confidence makes people prettier C.Good looks earn an extra penny D.How Plain Janes get a higher salary Good-looking people are usually paid more probably because________ .A.they look smarter B.they have higher degrees C.they are better at pleasing others D.they are more confident
