New Product Will Save lives

Drinking water that looks clean may still contain bugs(虫子),which can cause illness.
A small company called Genera Technologies has produced a testing method in three
stages,which shows whether water is safe.The new test shows if water needs chemicals
added to it,to destroy anything harmful.It was invented by scientist Dr. Adrian Parton,
who started Genera five years ago.He and his employees have developed the test together
with a British water company.
Andy Headland,Genera's marketing director,recently presented the test at a
conference in the USA and forecast good American sales for it.Genera has already sold 11
of its tests at$42,500 a time in the UK and has a further four on order. It expects to sell
another 25 tests before the end of March.The company says it is the only test in the UK to
be approved by the government.
Genera was formed five years ago and until October last year had only five employees;
it now employs 14.Mr Headland believes that the company should make around$19 million
by the end of the year in the UK alone.

The new product has been a commercial success in the USA.
A:Right
B:Wrong

4.BThe world is not only hungry,it is also thirsty for water. this may seem strange to you,since nearly 75% of the earth is covered with water. But about 97% of this water is sea water.Man can only drink and use the other 3% fresh water that comes from rivers,lakes,under-ground and other places. And we cannot even use all of that,because some of this fresh water has been made dirty.At the moment,this small amount(数量) of fresh water is still enough for us. However,our need for water is getting greater and greater. Only if we take steps to solve this problem now,we can get away from a serious world water shortage later on. The people of the world cannot have an enjoyable life without enough clean water.On one hand we should stop wasting this little water of ours,on the other hand we should find ways to reuse it,but this has not been done widely.Today,in most large cities,water is used only once and it then returns to the sea or runs into underground places.lf we can make it clean again,it can be used once more just as if it were fresh from a spring.But even if large cities reuse its water,we still would not have enough in the future. Where.could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh.So if we take all these steps,we'll be in no danger of drying up!( )26. Why does the writer say that the world is thirsty for water?A. The amount of fresh water is really very small.B. The people of the world waste too much water.C. The people of the world have to drink a lot of water every day.D. There are too many people in the world needing water.

    请阅读短文,完成此题。
    When we analyze the salt salinity(盐溶度 ) of ocean waters, we find that it varies only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation. In this manner, the salinity is increased, since the salt stays behind. If this is carried to the extreme, of course, white salt would be left behind; this, by the way, is how much of the table salt we use is actually obtained.
    The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of
    high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by-evaporation, or decreased by the addition of fresh water by precipitation.
    Normally, in hot regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
    A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
    In the Weddell Sea, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portion of the oceans of the world.

    Which of the following statements is TRUE according to the passage?
    查看材料

    A.Oceanic salinity has great effect on sea life.
    B.Many factors combine to cause changes in oceanic salinity.
    C.The movement of the water is related to the amount of salt.
    D.The temperature of the water has much to do with the oceanic salinity.

    答案:D
    解析:
    按照出题顺序,此题考查的是海水盐度变化的第三个原因。根据第四段可知,海水冻冰后,杂质析出,因此冰下的海水比冰的盐度高;冰融化后,海水盐度又会降低。所以答案为D,即海水温度与盐度有很大关系。

    Promising Resnlts from Cancer Study
    A new experimental vaccine(疫苗)has shown promising results in the fight against lung cancer.In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.
    Researchers have reported encouraging findings from this small study.Forty一three patients suffering from lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in tho advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.
    This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.It stimulates(刺激)the body's immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.
    The vaccine could be effective against other forms of cancer.It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.

    The vaccine could be effective against other forms of cancer. It offers great hope for the treatment of
    cancer in general,although further studies are needed before such treatment can be widely used.

    Patients in the early stages of the disease recovered more quickly in the trial.
    A:Right

    答案:B
    解析:
    题意:该疫苗治愈了参加试验的所有患者。文章第一段最后一句话“cured lung cancer in some patients and slowed the progress of the disease in others.”意思是有些患者被治愈了,有些 是病情得到缓解,由此可判断题干叙述错误。故木题选B。
    题意:超过四十人参加了这个试验。根据文章第二段第二句“Forty-three patients suffer- ing from lung cancer were involved in these trials.”可知,参加实验的有43人,所以题干叙述正 确,故本题选A。
    题意:试验中,处十癌症早期的患者恢复的更快。根据文章第二段最后两句“In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in theearly stages of the illness.”可知,癌症晚期的患者注射疫苗后有很大变化,癌症早期的没有多大起色,所以题干叙述错误,故本题选B。
    文章中说科学家做实验的地点在Dallas,没有提及病人来自哪里,故选C。
    题意:每个患者注射的都是一样的疫苗。从第三段的前两句话“This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.”可知,每支疫苗都是根据患者的免疫系统研究出来的,所以疫苗是不同的,因此答 案选择B。
    由文章第三段最后一句话“It stimulates the body' s immune system, which then recognizes that the cancer cells are harmful, and attacks and destroys them.”可知,这种疫苗会刺激身体里的 免疫系统,然后免疫系统辨认出身体里的有害癌细胞,攻击并摧毁它们。题干中activate的意 思是“激活”,与此句意思相符。故选A。
    题意:疫苗可能能够在治疗其他癌症上发挥作用。根据文章最后一段第一句“The vac-cine could be effective against other forms of cancer.”可知,题干叙述正确,故本题选A。第3部分:概括大意与完成句子

    本句意思是:这是水对人类独创性的挑战。根据含义仅有C项符合题意,to意思是“对于”,表示方向。
    需要填入关联词引导非限制性定语从句,由于先行词在句中做主语,因此选择D项。
    本句意思是:(巴比伦人)发明了管水的法律。本句句子主谓语完整,需要分词修饰law,由于law与water usage是施动关系,因此需要动词-ing形式,选择D项。
    本句意思是:中国人从水上获得灵感,修建了千里大运河。空格部分与前面的数字以连字符连接,因此只能选择单数形式共同构成修饰成分修饰名词canal,因此选择 D项。

    第一篇

    Water Resources on the Earth

    The second most important constituent(构成成分)of the biosphere(生物圈)is liquid water. This can only exist in a very narrow range of temperatures,since water freezes at 0℃and boils a 100℃.Life as we know it would only be possible on the surface of a planet which had temperature: somewhere within this narrow range.
    The earth's supply of water probably remains fairly constant in quantity.The total quantity of water is not known very accurately,but it is about enough to cover the surface of the globe to a depth of about two and three-quarter kilometers.Most of it is in the form of the salt water of the oceans一about 97 percent. The rest is fresh.But three-quarters of this is in the form of ice at the poles and or mountains and cannot be used by living systems until melted.Of the remaining fraction,which h somewhat less than one percent of the whole.There is 10—20 times as much stored underground water as there is actually on the surface.There is also a tiny,but extremely important fraction of the water supply which is present as water vapour in the atmosphere.
    Water vapour in the atmosphere is the channel through which the whole water circulation(循环) of the biosphere has to pass.Water evaporated(蒸发)from the surface of the oceans,from lakes and rivers and from moist(潮湿的)earth is added to it. From it the water comes out again as rain or snow,falling on either the sea or the land. There is,as might be expected, a more intensive evaporation per unit area over the sea and oceans than over the land,but there is more rainfall over the land than over the oceans and the balance is restored by the run off from the land in the form of rivers.

    The word"fraction"in the second paragraph means________.
    A:a large area
    B:a very small amount
    C:an important system
    D:a major source of information

    答案:B
    解析:
    文章第一段的第二句讲到液态水“only exist in a very narrow range of temperatures",虽然B(我们星球的表面)也有点道理,但是液态水对温度的要求很高,并非地球的所有表面都有液态水存在,所以答案D正确。
    第二段第一句提到地球上水的供给“remains fairly constant in quantity",数量上是恒定的,它就没有增加也不会减少,只不过会以不同的形态出现,所以选择B(保持不变)。
    问题是“地球上绝大部分淡水以什么形式出现?”第二段中间提到淡水时,说到“three-quarters of this is in the form of ice at the poles and on mountains",即3/4的淡水以冰的形式存在于两极和高山中,后面提到剩余部分的淡水存在于地下,但占比少于1%,所以选项A正确。
    词义辫析题, fraction有“小部分”的意思,考虑到前面提到地球97%的水以海洋咸水的形式存在,剩下的3%则以冰的形式存在于两极和高山,余下的自然不多,所以选B。
    第三段的最后一句说到“there is more rainfall over the land than over the oceans”,陆地的降雨比海洋要多,但没有提到河流和山脉的降雨比较,所以C正确。大气中的水蒸气是整个生物圈的水循环必经的途径。水从海洋的表面、湖泊、河流和潮湿的泥土中蒸发出来并补充到大气中。水以雨或雪的形式再次出现,降落在海洋或陆地上。可以预料到的是,海洋上空每单位面积的水蒸气比在陆地上空更为密集,但是,陆地比海洋有更多的降雨,水在陆地上以河流的形式流出以保持水资源的平衡。
