【题目】 I would like to talk to you about space vegetables, and to show you that space vegetables are healthy and good for you.

Space vegetables are grown from seeds (种子) that have been taken to and brought back from outer space. The seeds are affected by radiation (辐射) and low gravity in outer space. When they are brought back to the Earth, these seeds produce vegetables that are bigger, healthier and more nutritious (有营养的) than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could give us cancer as a result of their exposure (暴露) to radiation in space. People should not be scared, as space vegetables are actually perfectly healthy.

Here are some facts that you should know about space vegetables:

Space vegetables are grown from seeds that are carefully selected (选择). When seeds are brought back from space, people test the seeds to make sure that the vegetables they grow will be safe to eat. There are no traces of radiation after testing.

Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. Another popular space vegetable is the pepper (辣椒). Space peppers contain 20 percent more Vitamin C than normal peppers.

After genetically modified (基因改进的) foods come onto the market, people worry that they are eating unknown things. For example, if nut genes are put inside potatoes, people allergic (过敏) to nuts might get very sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified foods, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables, so they won't be harmful to your health.

Space vegetables

Space vegetables are healthy, good and safe for you to eat.

1taken to ensure the quality of spacevegetables.

Before being taken to the outer space, the seeds are carefully selected.

When being brought back from space, seeds are tested to see 2 there are traces of radiation which might lead to cancer. The testing has proved that they are perfectly healthy.

Advantages of space vegetables

After being affected by the radiation and low gravity in outer space, the seeds 3 into bigger and healthier vegetables. For example, space peppers contain more Vitamin C.

Space tomatoes can be 4much longer than normal tomatoes

There is no 5 of eating something because none of the genes is changed.

【答案】

1Steps

2whether/ if

3grow

4kept/ stored

5harm

【解析】

文章主要介绍了太空蔬菜营养价值和对人体健康的影响。

1要点归纳题,此题所在表格后面例出的两个小点都是在介绍关于确保太空蔬菜质量的步骤,所以填step的复数形式表示步骤,故填:Steps

2细节理解题,由“When seeds are brought back from space, people test the seeds to make sure that the vegetables they grow will be safe to eat. There are no traces of radiation after testing.当种子从太空带回来时,人们会对种子进行测试,以确保他们种植的蔬菜能够安全食用。检测后没有辐射痕迹。”,可知当种子从太空带回来时,会被检测是否有可能导致癌症的辐射痕迹,故填:whether/ if

3细节理解题,有“When they are brought back to the Earth, these seeds produce vegetables that are bigger, healthier and more nutritious (有营养的) than normal vegetables.种子受到辐射和外层空间低重力的影响。当它们被带回地球时,这些种子产生的蔬菜比普通蔬菜更大、更健康、更有营养”,故填:grow

4细节理解题,由“For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.例如,太空番茄的保鲜时间为20天,比普通番茄长一周。”,这里用的被动语态(be+done)表示被保存,故填:kept/ stored

5细节理解题,由"This means that no new genes are put into the vegetablesThereforethey won't damage your health"可知太空蔬菜不会损害人的健康,由此可知此题用no harm表示没有伤害,故填:harm
