Throughout this long, tense election, everyone has focused on the presidential candidates and how they’ll change America. Rightly so. But selfishly, I’m more fascinated by Michelle

Obama and what she might be able to do, not just for this country, but for me as an African-American woman. As the potential First Lady, she would have the world’s attention. And that means that for the first time people will have a chance to get up close and personal with the type of African-American woman they so rarely see.

Usually, the lives of black women go largely unexamined. The prevailing theory seems to be that we’re all hot-tempered single mothers who can’t keep a man. Even in the world of make-believe, black women still can’t escape the stereotype of being neck-swirling, eye-rolling, oversexed females raised by our never-married, alcoholic mothers.

These images have helped define the way all black women are viewed, including Michelle Obama. Before she ever gets the chance to commit to a cause, charity or foundations as First Lady, her most urgent and perhaps most complicated duty may be simply to be herself.

It won’t be easy. Because few mainstream publications have done in-depth features on regular African American women, little is known about who we are, what we think and what we face on a regular basis. For better or worse, Michelle will become a stand-in for us all.

Just as she will have her critics, she will also have millions of adoring fans who usually have little interest in the First Lady. African-American blogs have all written about what they’d like to see Michelle bring to the White House---mainly showing the world that a black woman can support her man and raise a strong black family. Michelle will have to work to please everyone---an impossible task. But for many African-American women like me, just a little of her poise, confidence and intellect will go a long way in changing an image that’s been around for far too long.

69.  Why does Michelle Obama hold a strong fascination for the author?

A. She serves as a role model for African-American women.

B. She possesses many admirable qualities becoming a First Lady.

C. She will present to the world a new image of African-American women.

D. She will pay closer attention to the interests of African-American women

70. What is the common stereotype of African-American women according to the author?

A. They are victims of family violence. 

B. They are of an inferior social group.

C. They use quite a lot of body language.

D. They live on charity and social welfare.

71. What does the author say about Michelle Obama as a First Lady?

A. However many fans she has, she should remain modest.

B. She shouldn’t disappoint the African-American community.

C. However hard she tries, she can’t expect to please everybody.

D. She will give priority to African-American women’s concern.

D

Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?

Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work, she has to go to the stomach – bypass surgery (胃部迂回手术), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.

Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.

Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.

Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制剂). But after years of trying, it had to be given up.

What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (药物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”

       C.new drugs will be developed in 10 years.

       D.ghrelin levels are higher in people on diet.

       A.ghrelin and leptin                       B.hormone and medicine

       C.brain and body chemicals                   D.stomach and food

50.What can we infer from the passage?

       A.People with a lower ghrelin level go hungry easily.

       B.Doctors managed to use leption to control the appetite.

       C.Doctors are optimistic about how to lose weight healthily.

       D.The loss of appetite in bypass aptient is linked to leptin
