    阅读下面短文，根据所读内容，在文章后小题的空格里填入一个最恰当的单词。

    Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way of making a contribution to social work and having a big effect on the community. It helps to save lives and helps those who are in need of blood because of bad conditions or the heavy loss of blood during operations or in accidents.

    You are able to give or donate blood every three or four months. The doctors say it is not bad for your health. It is such a beautiful way of making a huge difference to someone’s life and you can always be proud of it if you make a valuable contribution to society. Blood donation is not a big problem, but you need to keep a few points in mind.

    Before donating blood, make sure that the ferrum(铁) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation with an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. You will not feel weak at the same time.

    For required hemoglobin(血红蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.

    For a good blood flow(血流) in your body, drink at least 6-7 glasses of water every day. Completely avoid taking alcohol or caffeine a day before and after giving blood. Do not smoke cigarettes(烟) half an hour before giving blood.

    When you are going for blood donation, be relaxed, which helps keep the right blood pressure(血压). During the blood donation activity, you can breathe deeply and try to calm yourself down. Don’t take part in some other activities.

    When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.

    Take a rest for 15 minutes after completion of the donation. It helps you to feel relaxed and energetic.

    Eat something and drink juice before leaving the blood donation center. Make sure that you have meals after donating blood. Smoking should be prevented for one hour after the process. Don’t join in some activities at once, for example, driving.

    Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

    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.

    Title: Space Vegetables

    Space vegetables are healthy, good and 1. for you to eat.

    Steps taken to ensure the quality of space vegetables

    Before being brought to the outer space, the 2. are carefully selected.

    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
