If you see someone drowning, speed is very important. Once you get him out of the water, if he isn’t breathing, you have four minutes before his brain is completely destroyed. Support his neck, tilt（使翘起）his head back and press his chin（下巴）upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn’t work, start mouth-to-mouth breathing. Press his nostrils（鼻孔）together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until help arrives.

To bring a child back to life, keep your lips around his mouth and nose and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue grey color, you can feel no pulse（脉搏）,then pressing is the last chance of saving his life.

With arms straight, rock（摇动）forwards, pressing down on the lower half of the breastbone. Don’t be too hard or you may break a rib（肋骨）. Check how effective you are seeing if his color improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.

1.This passage is mainly about ________.

A. how to save people out of the water

B. how to give first aid to people who are drowning

C. how to do mouth-to-mouth breathing

D. how to save a child from a river

2.Once you get a drowning man out of the water, if he isn’t breathing, you must first ________.

A. get him breathing again

B. take him to the nearest hospital as soon as possible

C. find someone to help you

D. call the First Aid Centre

3.In the last paragraph, the word “rescue” means ________.

A. breath            B.　 doctor        C.　 help            D.　 pulse

4.If the drowning boy has no pulse, ________.

A. pressing his chin upwards is enough to get him breathing again

B. blowing air into his mouth is sure to save his life

C. pressing his nostrils together with your fingers can work

D. pressing his chest is the last chance of saving his life

5.Which of the following statements is true?

A. If a man fails to breathe for four minutes, his brain will be completely destroyed.

B. If you see someone drowning, you must give him mouth-to-mouth breathing.

C. Don’t stop pressing his chest, if the drowning man starts breathing again.

D. When pressing, you can do it as hard as you can.

In the United States, teaching is very important. If teachers do not teach well, students complain. If many students do not understand, people think that the teacher does not do a good job. The teacher has big responsibility to make sure students understand. In a sense, students are consumers and the teacher is offering services.

Students have the right to evaluate their teachers, and they usually do so at the end of each course. That evaluation includes lots of aspects of teaching, such as explanation, preparation, using good examples, answering questions, and organization of classes.

Students are supposed to read required textbooks and recommended books before classes. Without reading them, they will find it very difficult to understand the class. Basic courses on doing research and writing papers are taught at the beginning of the program. They teach things very concretely(具体地) and clearly. Students are expected to apply what they have learned to their studies.

Classes are usually divided into lectures and seminars. There are some lecture classes, where the teacher just gives a lecture, and students ask questions at the end. Most graduate level classes are lectures and discussions. Participating in discussions is very important. Higher level classes involve very little lecturing. They emphasize discussion and presentation by the students.

1According to the passage, good teachers should ___________.

A．try to please their students

B．treat their students as consumers

C．understand their students well

D．made sure their students understand

2What are students expected to do before attending a class?

Plants are very important living things. Life could not go if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. So animals and man need plants in order to live. This is why we find that there are so many plants around us.

If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants.

Flowering plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit.

Most non-flowering plants don’t grow from seeds. They grow from spores(孢子). Spores are so small and light that they can float in the air. We may say that spores are quite the same as the seeds. When these spores fall on wet and shady places, they usually grow into new plants.

1.The main idea of the passage is that __________.

2.Which of the following is NOT TRUE?

3.The word “non-flowering ” in this passage means __________.
