阅读下面短文，并按照题目要求用英语回答问题。

[1] Perhaps you are an average student with average intelligence. However, you can receive better grades if you want. Yes, even students with average intelligence can be top students without additional work. Here’s how:

[2] Plan your time carefully. Make a list of your weekly tasks. Then make a schedule of your time. Be sure to set aside enough time to complete your normal reading and work assignments. Of course, studying shouldn’t occupy all of the free time on the schedule.

[3] Make good use of your time in class. Listening to what the teacher says in class means less work later. Take notes to help you remember what the teacher says.

[4] Skim before you read. Look over a passage quickly before you begin to read it more carefully. As you preview the material, you get some idea of the content and how it is organized. Later when you begin to read you will recognize less important material and you may skip some of these portions. Skimming helps double your reading speed and improve your comprehension as well.

[5] Review regularly. Go over your notes as soon as you can after class. Review important points mentioned in class as well as points you remain confused. If you know what the teacher will discuss the next day, skim and read that material, too. If you review your notes and textbook regularly, the material will become more meaningful and you will remember it longer. Regular review leads to improved performance on tests.

[6] Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. The world won’t end if you don’t pass a test, so don’t worry excessively about a single test.

Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air.

One of these is a condition called hypoxia (缺氧症). It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules （分子） cross the tissues (组织) in the lungs and reach the bloodstream.

The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body.

One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to fix the situation by beating harder and faster. This can make the traveler feel tired.

These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack.

Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body’s ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying.

1.The author writes the passage mainly to ___.

2.According to the passage, what leads to hypoxia?

3.The underlined part “fix the situation” means “___”.

4.Why should passengers not smoke or drink before flying?

5.Do you think which the following title is the best title for this passage?
