C: lack sufficient means to combat lead pollution D: still consider lead pollution a problem 答案:D 解析: 推理题。题干：通过最后一段能推测出什么? 最后一段提到了两项研究说明某些生态系统对大气污染的减少给出了快速的回应，但是这并不能作为进一步污染行为的许可证。因此D正确，科学家们仍然认为铅污染是个问题。 (41) 根据下面材料，回答题。 It is predicted that there will be 5 scientific breakthroughs in the 21st century. We'll knowwhere we came from. Why does the universe exist? To put it another way, why is theresomething instead of nothing? Since the 1920s, scientists have known the universe isexpanding, which means it must have started at a definite time in the past. They even havedeveloped theories that give a detailed picture of the evolution of the universe from the timeit was a fraction of a second old to the present. Over the next couple of decades, thesetheories will be refined by data from extraordinary powerful new telescope. We will have abetter understanding of how matter behaves at the unfathomably high temperatures andpressures of the early universe. We'll crack the genetic code and conquer cancer. In 19th century operas, when the heroinecoughs in the first act, the audience knows she will die of tuberculosis in Act 3. But thanksto 20th century antibiotics, the once dreaded, once incurable disease now can mean nothingmore serious than taking some pills. As scientists learn more about the genetic code and theway cells work at the molecular level, many serious diseases--cancer, for one- will becomeless threatening. Using manufactured "therapeutic" viruses, doctors will be able to replacecancer causing damaged DNA with healthy genes, probably administered by a pill or injection. We'll live longer (120 years?) If the normal aging process is basically a furious, invisiblecontest in our cells- a contest between damage to our DNA and our cells ability to repair thatdamage- then 21st century strides in genetic medicine may let us control and even reversethe process. But before we push scientists to do more, consider: Do we really want to live ina world where no one grows old and few children are born because the planet can hold onlyso many people? Where would new ideas come from? What would we do with all that extra time? We'll "manage" Earth. In the next millennium, well stop talking about the weather but willdo something about it. Well gradually learn how to predict the effects of human activity onthe Earth,its climate and its ecosystems. And with that knowledge will come an increasingwillingness to use it to manage the workings of our planet. We'll have "a brain road map". This is the real "final frontier" of the 21st century: The brainis the most complex system we know. It contains about 100 billion neurons (roughly thenumber of stars in the Milky Way), each connected to as many as 1,000 others. Early in thenext century, we will use advanced forms of magnetic resonance imaging to producedetailed maps of the neurons in operation. We'll be able to say with certainty which ones areworking when you read a word, when you say a word, when you think about a word, and soon. The sentence "In 19th century operas, when the heroine coughs in the first act, the audienceknows she will die of tuberculosis in Act 3" means__________. A: there was not antibiotics at that timeB: tuberculosis was a terrible disease that couldn't be cured during 19th centuryC: the health of the heroine was very poorD: this was a common situation in the 19th century operas 答案:B 解析: 细节题。题干：句子“在19世纪的戏剧中，如果女主角在第一幕开始咳嗽，观众们就会知道在第三幕时会因为肺结核而死去” 的意思是__________。第二段说如果女主角在第一幕中咳嗽的话，观众便会知道她将在第三幕中因肺结核而死。接着说这种病0nce dreaded和once incurable disease，即“那样可怕的不治之症”。可知B正确。 (42) It will become easy to cure some serious diseases because__________. A: scientists will crack the genetic code B: "therapeutic" viruses will be used C: healthy genes will be used to replace cancer causing damaged DNA D: all of the above 答案:D 解析: 推理题。题干：治疗一些严重的疾病会变得很容易，因为__________。A、B、C 在第三段都提到这一点，因此选D。 (43) According to the passage, the normal aging process is__________. A: a process in which people become older and older B: a contest that can be seen C: a long process of struggling D: a fight between damaging DNA and preparing the damage 答案:D

Keep on Fighting

Turning once again to the question of invasion, I would observe that there has never been a period in all these long centuries of which we boast when an absolute guarantee against invasion, still less against serious raids, could have been given to our people. In the days of Napoleon the same wind which would have carried his transports across the Channel might have driven away the blockading (封锁) fleet. There was always the chance, and it is that chance which has excited and befooled (愚弄) the imaginations of many continental tyrants. Many are the tales that are told. We are assured that novel methods will be adopted, and when we see the originality of malice (怨恨), the ingenuity of aggression, which our enemy displays, we may certainly prepare ourselves for every kind of novel stratagem (战略) and every kind of brutal and treacherous (奸诈)maneuver (花招). I think that no idea is so outlandish (古怪的) that it should not be considered and viewed with a searching, but at the same time, I hope, with a steady eye.

We must never forget the solid assurances of sea power and those which belong to air power if it can be locally exercised. I have, myself, full confidence that if all do their duty, if nothing is neglected, and if the best arrangements are made, as they are being made, we shall prove ourselves once again able to defend our island home, to ride out the storm of war, and to outlive the menace (威胁) of tyranny, if necessary for years, if necessary alone. At any rate, that is what we are going to try to do. This is the resolve of His Majesty's government - every man of them. This is the will of parliament and the nation. The British Empire and the French republic, linked together in their cause and in their need, will defend to the death their native soil, aiding each other like good comrades to the utmost of their strength. Even though large tracts of Europe and many old and famous states have fallen or may fall into the grip of the Gestapo and all the odious (可憎的) apparatus of Nazi rule, we shall not flag (变弱) or fail.

We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our island, whatever the cost might be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills, we shall never surrender, and even if, which I do not for a moment believe, this island or a large part of it were subjugated (征服) and starving, then our empire beyond the seas, armed and guarded by the British fleet, would carry on the struggle, until, in God's good time, the new world, with its power and might, steps forth to the rescue and the liberation of the old.

16Throughout Britain's history, there has been no guarantee that an invasion would not happen.
