【题目】阅读理解B
I am Peter Hodes, a volunteer stem courier. Since March 2012, I've done 89 trips of those, 51 have been abroad, I have 42 hours to carry stem cells(干细胞) in my little box because I've got two ice packs and that's how long they last, in all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, we've got 72 hours at most, So I am always conscious of time.
I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said: “Well, I'm really sorry, I've got some bad news for you-there are no fights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient-please, please, you've got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for mere-routed(改道) me through Newark and got me back to the UK even earlier than originally scheduled.
For this courier job, you're consciously aware than that box you're got something that is potentially going to save somebody's life.

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Both men and women are living longer these days in industrialized countries. In general, they can expect to live six or seven years more than men. One reason for this is biological.
One important biological factor that helps women live longer is the difference in hormones between men and women. Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.
They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.
Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman's body cells have a tendency(向) to age more slowly than a man's. Others think that a man's body cells have a tendency to age more quickly.
A. However, women, on average, live longer |
