| 请认真阅读下面短文,在短文后表格中的空白处填入适当的单词(注意:每空1个单词). | ||||||
| Whenever we meet with difficulty or failure, teachers, parents or others often say to us or perhaps we say to ourselves, "Never give up." These can be encouraging words and words of determination. A person who believes in himself will keep trying to reach his goal no matter how many times he fails. In my opinion  ,the quality of determination to succeed is an important one to have. Therefore, I believe that we should never give up. One reason is that if we give up too easily, we will rarely achieve anything. It is not unusual for us to fail in our first attempt at  something new, so we should not f eel disappointed and should try again. Besides, if we always give up when we fail , we will not be able to develop new skills and grow. Another reason we should never give up is that we can learn from our mistakes so that we can not make the same ones. If we do not try again, the lesson we have learned is wasted. Finally, we should never give up because as we work to reach our goals, we develop confidence, and this confidence can help us succeed in other areas of our lives. If we never challenge ourselves, we will begin to doubt our abilities. In short, it is important that we do not give up when working for our goals. Whether we succeed in the end or not , we will learn something , and what we learn will help us to become better and more confident. Furthermore, if we give up , we have no chance of attaining our goals any more , but if we keep making great efforts, there is always a chance that we will succeed one Topic: Never Give Up

about. It is completely wrong to think that the diver is cushioned (缓冲) by the water below-this could not be
further from the truth. When jumping from a cliff that is over 70 feet high, a diver hits the water at over 46 mph
(miles per hour). Such high speeds make the point of contact feel like a wall, so the diving skills are very
important.
Professional divers are trained and well-prepared to make dives. However, non-professionals should never
dive because a diver's body position (体位) at the time of contacting water is very important to his or her safety.
Because of the great danger, divers should always seriously think about their skills before trying any moves.
Although there is no truly safe way to jump off a cliff, non-professional divers are encouraged to pencil dive.
To do a pencil dive, the jumpers leap their feet first off the cliff, keep arms at their sides with legs together and
pointing downward. The diver should keep the body tight and vertical (垂直的). This is safer because it makes
the point of contact smaller when the diver enters the water and puts less stress (压力) on the body.
Wearing a wet suit while diving will result in less pain. So it is wise for new divers to wear wet suits. But
professional divers suggest staying away from water shoes. Although wearing shoes might seem like a good
idea, they actually increase the force of impact(冲击力) because they increase the surface area of the diver at
impact. The increased force of impact puts stress on a diver's body and can lead to broken bones. Without a
doubt, diving without shoes is the safer way to go.
Besides the height, speed, water depth and body position, it is also important for divers to make wise
decisions when they are thinking about diving. Cliff diving tests both a person's physical and mental(心理的)
skills, so it is never a good idea to jump with a sudden idea. A person needs to be of sound mind and in good
health to even think about a dive. One should never try a dive if he has drunk wine. What's more, a person
should never make someone who is not feeling 100% confident dive.
B. This idea is thought to be completely wrong.
C. It depends on the real situation on the spot.
D. Nobody knows whether this idea is true or not.
B. cause the diver to feel uncomfortable
C. make the point of contact bigger
D. certainly lead to broken bones
B. professional and strong
C. creative and smarty
D. confident and brave
