听力原文： A team of scientists recently began a project to measure the effects of loud noises on sea animals. If the sounds don't harm the animals, then the researchers can go ahead with a plan to transmit sound waves through the Pacific Ocean to take the earth's temperature. Sound travels faster through warm water than cold water. By analyzing the speed of sound through the ocean over time, the scientists will be able to determine if cur planet is warming up. The experiment was nearly cancelled more than a year ago because environmental groups fear that the sound will confuse or harm sea-animals. So scientists are conducting tests on the animals first. The researchers lowered a loud speaker that emits low frequency sound about 1,000 meters beneath the ocean. Scientists at the site transmit sound waves into the ocean. Radio transmitters attached to some of the sea animals help the researchers keep track of the animals' movements. If sea-animals are distressed by the sounds, they would swim away from the speakers. So far, there aren't any signs that the animals are being harmed. Researchers at the site noticed that large numbers of sea-animals swim near the speaker whether it was turned on or off, but it is still too soon to know for sure, the scientists admit. The test will continue through September. "If all goes well," they say, "we can begin measuring temperature changes on our planet."

Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and insect never more than six.
How many spiders are engaged in this work in our behalf？ One authority on spiders made a census of the spiders in grass field in the south of England, and he estimated that there were more than 2 250 000 in one acre; that is something like 6 000 000 spiders of different kinds on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.
(33)
A．Because they are beneficial insects.
B．Because they destroy insects without hurting us in any way.
C．Because they protect insect-eating animals.
D．Because they include some of the greatest enemies of the human race.

W: No, I did not approve of suffragettes.
M: So you think in the long term...
W: In the long term, no harm was done. As long as their demonstrations were peaceful.
M: Do you think it would matter very much if women hadn't achieved the vote？
W: I don't think it would have made a great deal of difference, no, but there are certain things they've done—those been Members of Parliament—that have been very useful in helping women in their jobs, in other vocations. I think it's good that it happened. But I wish it happened a little bit more peacefully, perhaps.
M: What sort of things can you remember, what other sorts of demonstrations do you remember？
W: Marching, they were marching. But of course those were much more peaceful days, nobody interfered with their marches. There were a few boos here and there and a lot of clapping.
M: Did you, actually know any suffragettes yourself？
W: Well, my friends, my Close friends, were not suffragettes but I had one or two friends, not very close friends, that were. And we used to have great arguments and I used to say I didn't want the vote, I don't want to vote.
M: How did they react to that？
W: They said I ought to join the movement but I said no, I don't want to vote.
M: So you don't mind actually joining men in their world of work and sport but you're happy to leave politics to men.

听力原文： Why, you may wonder, should spiders be our friends？ (26)Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. (27)We owe a lot to the birds and beasts which eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, (26)spiders never do the harm to us or our belongings.
Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, (28)for a spider always has eight legs and insect never more than six.

Is that label accurate？ Is it intolerant to challenge another's opinion？ It depends on what definition of opinion you have in mind. For example, you may ask a friend, "What do you think of the new Ford cars？" And he may reply, "In my opinion, they're ugly." In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, "It's pointless to argue about matters of taste."
But consider this very different use of the term. A newspaper reports that the Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not state their personal preferences, their mere likes and dislikes. They stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation.
Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence.
Is everyone entitled to his opinion？ Of course, this is not only permitted, but guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others.
Which of the following statements is TRUE, according to the author？
A．Everyone has a right to hold his own opinion.
B．Free expression of opinions often leads to confusion.
C．Most people tend to be careless in forming their opinions.
D．Casual use of the word "opinion" often brings about quarrels.
