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 that have been taken to and brought back from outer space. The seeds are affected by the radiation (辐射) and low gravity in outer space. When they are brought back to 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. When seeds are brought back from space they are tested to make sure that the vegetables they grow will be safe to eat. There are no traces (痕迹) 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 peppers. Space peppers contain 20 percent more vitamin C than normal peppers.
After modified (转基因) foods came onto the market people worried that they were eating unknown things. For example if nut genes are put inside potatoes people allergic (过敏的) 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. Therefore they won’t damage your health.

Steps taken to ensure the quality of space vegetables | Before being brought to outer space the 2 are carefully selected. |
When being brought back from space vegetables are 3 to see whether there are traces of radiation which might 4 to cancer. The testing has 5 that they are perfectly healthy. | |
6 of space vegetables | After being 7 by the radiation and low gravity in outer space the seeds produce bigger and healthier vegetables. For example space peppers contain 8 vitamin C. |
Space tomatoes stay 9 longer than normal tomatoes. | |
Don't worry. There is no 10 of eating something that may damage your health because none of the genes is changed. |
