Human cloning technology could be used to reserve heart attacks. Scientists believe that they may be able to treat heart attack by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged, and other problems may be solved if human cloning and its technology are not forbidden.

With cloning, infertile couples could have children. Current treatments for infertility, in terms of percentages, are not very successful. Couples go through physical and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before.

We should be able to clone the bone marrow（骨髓） for children and adults suffering from leukemia（白血病）. This is expected to be one of the first benefits to come from cloning technology. We may learn how to switch cells on and off through cloning and thus be able to cure cancer.

Cloning technology can be used to test for and perhaps cure gene-related diseases. The above is just a few examples of what human cloning technology can do for mankind. This new technology promises unprecedented （前所未有的）advancement in medicine if people will release their fears and let the benefit begin.

1.What does the underlined word “infertile” (paragraph 2) most probably mean?

A. with physical and emotional problems

B. short of time and money

C. unable to give birth to children

D. separated from each other for a long time

2.According to the text, one of the first expected benefits from cloning technology is in ______.

A. the treatment of mental diseases

B. the reserve of heart diseases

C. the cure of gene-related diseases

D. the bearing of babies

3.According to the writer, the main problem with the development of human cloning technology is that__________.

A. it has brought about benefits so far

B. it may be out of human control

C. people still know little about it

D. people are afraid of such technology

“Soon, you’re going to have to move out!” cried my neighbor upon seeing the largest tomato plant known to mankind, or at least known in my neighborhood.
One tiny 9-inch plant, bought for $1.25 in the spring, has already taken over much of my rose bed, covering much of other plants, and is well on its way to the front door.

Roses require a good deal of care, and if it weren’t for the pleasure they give, it wouldn’t be worth the work. As it is, I have a garden full of sweet-smelling roses for most of the year. Bushes must be pruned(剪枝) in early spring, leaving ugly woody branches until the new growth appears a few weeks later. It was the space available in the garden that led me into planting just one little tomato plant. A big mistake.
Soil conditions made just perfect for roses turn out to be even more perfect for tomatoes. The daily watering coupled with full sun and regular fertilizing (施肥) have turned the little plant into a tall bush. The cage I placed around it as the plant grew has long disappeared under the thick leaves.
Now the task I face in harvesting the fruit is twofold; First, I have to find the red ones among the leaves, which means I almost have to stand on my head, and once found I have to reach down and under, pick the tomatoes and withdraw(缩回) my full fist without dropping the prize so dearly won. I found two full-blown white roses completely hidden as I picked tomatoes in June. But they were weak and the leaves already yellow for lack of light.
Here I am faced with a painful small decision: To tear up a wonderful and productive tomato plant that offers up between ten and twenty ripe sweet tomatoes each day or say goodbye to several expensive and treasured roses. Like Scarlett in Gone With the Wind, I’ll think about that tomorrow.
