D
There are three separate sources of danger in supplying energy by nuclear power (原子能)
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak(泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster(災難) is extremely high.
71. Which of the following is FALSE?
A. It is possible that a leak or an explosion occurs at a power station.
B. It is unusual for radioactive materials to be transported across land.
C. The containers are likely to be broken by an earthquake.
D. Nuclear wastes remain dangerous in most cases for many years.
72. The author thinks that the ways to store nuclear wastes are ＿＿＿ .
A. easy B. impossible C. reasonable D. ineffective
73. What do we learn from the last paragraph?
A. The power station is a safe place.
B. The dangers of nuclear energy can be prevented.
C. The general public are strongly against the nuclear program.
D. By itself, none of the three dangers is very likely to cause much worry.
74. What is this passage about?
A.Uses of nuclear power. B.Dangers from nuclear power.
C.Public anger at nuclear power. D.Accidents caused by nuclear power.
75. As for the possible dangers of nuclear power, ______.
A. none of them can be completely avoided
B. effective measures have been taken to avoid them
C. man will never be able to do anything about them
D. one is usually the cause of another

There is no doubt about it. The best way to learn new words is to do it unconsciously. I don’t mean while you’re unconscious. I mean while you are unconscious of the fact that it is sinking in.
That is how I learnt the 30,000 words in my vocabulary by living in an English-speaking world, mother tongue. I just pick them up. But the problem is that some of them may be misunderstood. Now, to misunderstand does not mean not to understand. To misunderstand is to understand but incorrectly.
The 5% mislearnt of all the words we “know” will be the least frequently used words, as the more frequently used words are less likely to be mislearnt. Some of the misunderstandings may live with all our lives, without knowing that we got them wrong.
Many English teachers think that this natural method of learning words in one’s own mother tongue can be used for a second language learning. They teach their students how to play the Guessing Game. “There is no time to look up in your dictionaries all the new words you come across,” They will say. “You have to practise guessing what the word means from the context.”
This method of guessing in a second language learning does not work. It may succeed in many cases, but results in hundreds or thousands of wrongly-guessed meanings of words.
And what’s more, there are more separate meanings than there are words themselves. Our learners’ dictionaries usually have many meanings. A good dictionary is what makes self-learning possible.
Don’t guess! Look it up!
67. It is certain that the best way to learn new words is________.
A. to learn them by oneself
B. to learn by living in an English-speaking world and using them frequently
C. to guess them from the context
D. to get more separate meanings of each word^
68. The underlined word “them” in paragraph 2 refers to_______. 
A. the 30,000 words B. English teachers
C. misunderstood words D. frequently used words
69. Which of the following is most likely NOT true?
A. Some of the words the writer knows must have been misunderstood.
B. Most of the 30,000 words the writer learned are frequently used ones.
C. How many words the writer got wrong are not known.
D. All the words the writer knows were learned by reading them.
70. It can be inferred that_____________.
A. when somebody is conscious, he or she usually can’t learn new words by heart.
B. We must use the words as often as possible in order to master them.
C. It’s the best way to learn new words that one should only guess their meanings from the context
D. Only dictionaries can help us learn language well.
