Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way of contributing 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 due to bad condition or the heavy loss of blood during operations or in accidents.

You are able to give or donate blood every three or four month, and it is such a beautiful way of making a huge difference to someone’s life and you can always be proud of it after making 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 you body is high enough and for that you should take a healthy diet. Do not go for blood donation on 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. Afterwards, you will not feel faint or weak.

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 in your body, drink at least 6-7 glasses of water daily. Completely avoid, a day before and after giving blood, taking alcohol, caffeine, etc. Do not smoke half an hour before giving blood.

When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity take a deep breath and try to calm yourself. 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 avoided for one hour after the process. Avoid some activities right away, 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.

Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how:

 (1) Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don’t forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

 (2) Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television! When you sit down to study, concentrate on the subject.

 (3) Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says.

 (4) Study regularly. When you get home from school, go over your notes. Review the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material in advance. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.

 (5) Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be overly worried.

There are other methods that might help you with your studying. You will probably discover many others after you have tried these.

How to become a better student

Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there's a whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job’s pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas:

    Do you enjoy working with computers？

    I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well.

      Do you prefer working alone or with other people?

    There are isolating jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.

How do you handle change?

Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine.

What type of work environment do you enjoy？

    This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly.

How do you like to get paid?

    Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.

Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better.

When you read a story in English, do you read it for the story 61       for the English? This is a question that is not so62       (fool) as it may seem, for I find that many students of English pay far more attention to the story 63       to the English. For instance, they care for how the mystery in the story64       (solve), but do not remember a single sentence in the story and cannot tell what preposition(介词) is used before a certain word in the speech of a certain character.  

Of course, if you want to know the 65      only, you need not bother about the language. But a student of English is different 66        a student of stories or what is called the general reader. As you may also have learned from the above, you ought to read not only very67__  (careful) but also aloud68      you learn the passage by heart and can recite it as if it were your own. On 69       hand, this will teach you many useful words and phrases; on the other hand, it70       (help) you to avoid many mistakes and faults in expression.

Global warming is one of the major environmental problems we are facing today. Scientists think a further rise in the carbon dioxide levels will make this situation worse. The greenhouse effect causes the earth’s heat to be trapped in the atmosphere, which results in the increase in temperature. This, in turn, has an effect on various plants and animals. Global warming makes it not easy for some of them to survive.

Ozone depletion means a drop in the quantity of the ozone(臭氧) in the earth’s stratosphere (平流层). The ozone hole in the Antarctic is mainly due to the release of CFCs ( a type of gas). Because of ozone depletion, humans are facing various problems such as the harmful effects of UV rays.

Water pollution is caused when wastes are thrown into water. What’s more, many harmful chemicals are also put into water, which causes the deaths of many wild animals and endangers the health of humans.

The increasing population is causing a loss of natural resources. This is related to various human activities. For example, overfishing has caused many kinds of fishes to die out. Forests are being cleared to meet the rising demand for paper, wood, even for land. Mining, the work of getting gold, coal etc out of the earth, has led to a further drop in mineral resources. If we used up all the resources, how could our children survive on this planet?

These are some of the current environmental problems we are facing today. Only with an effort from each person, can we hope to save our planet from being destroyed.
