How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

73.According to Paragraphs 3 and 4, if a person is at a higher genetic risk, it is__________.

A. advisable not to let him know          B. impossible to hide his disease

C. better to inform him immediately      D. necessary to remove his anxiety

【答案】A

【解析】根据这两个自然段可知，如果你提前被告知你将来可能患某种可怕的疾病会mess you up。

阅读下列短文，从所给的四个选项中，选出最佳答案

　Scientists had long dreamt of splitting the atom(原子) and let out some of its huge quantity of energy．They didn't find out how to do it until the 1940s．

　Uranium is one of the matters whose atoms can be split fairly easily．A small particle(粒子) is added to an atom of uranium, which then breaks into two smaller atoms．The change has other results．It makes the uranium very hot．It also produces two or there free particles of the kind first added．These free particles move around, splitting other uranium atoms, and so begins a “chain reaction”(链式反应), which produces more heat and more free particles．Both the heat and the chain reaction are important．

　A gas or a liquid is sent into the reactor（反应堆）to collect and carry away the heat．It is used to boil water, and the steam so produced drives the machinery which produces electricity．The chain reaction allows the process(过程) to continue．The reaction, which could be very rapid, is slowed down by a certain matter, which surrounds the fuel．

　Today, many people are wondering how long the world's store of coal and oil will last．Both these fuels, like uranium, are producers of heat energy．Is atomic energy the answer to the world's energy problem?

(1) Which of the following words can take the place of the underlined word“splitting”?

(3) “Chain reaction”means______．

[　　]

A．free particles produced in the reaction will split other atoms, which in turn will produce more free particles

B．free particles will split more atoms after splitting some atoms

C．atoms split by free particles will continue to split

D．reaction can go on and on with the help of a chain of particles

(4) Which of the following orders shows rightly how a nuclear (原子能的) power plant works?

[　　]

a．Heat is made to boil water．

b．The machinery produces electricity

c．The chain reaction produces heat．

d．Heat is collected and carried away by a gas or a liquid．

e．Steam so produced drives the machinery．

A．d-c-e-b-a　　　B．c-d-a-e-b

C．b-d-e-a-c　　　D．c-a-d-b-e

(5) What fact does this passage lead you to believe?

[　　]

A．Many people wonder whether the world's store of coal and oil will last long．

B．Coal, oil and uranium are fuels, which can produce heat．

C．The world's store of coal and oil will last a very long time．

D．Atomic energy has given people hope to solve the world's energy problem．

阅读下面短文，从每题所给的四个选项中，选出一个最佳答案.

Dear editor:

　　You can find language pollution whenever you open a newspaper or turn on your TV set, listen to a popular song at various advertisements (广告). Language pollution exists almost everywhere and can be seen in the following places:

    1.Chinese characters are written in the complex (复杂的) form. Although simplified (简化的) Chinese characters were accepted for use many years ago, it seems that more and more people like Chinese characters written in the complex form.

    2.Many goods are produced in China but carry foreign names, which sound strange and have no meaning at all.

    3.Words and expressions being used have a bag meaning. “Ba” (霸), which means bully in Chinese, is one example. Now there are a lot of goods, restaurants, even factories or films, with “Ba” in their names.

    4.There are too many incorrect grammatical expressions. Some films have strange names and incorrect grammatical structures (结构). “Ai ni mei shang liang”, Which means “I love you without consulting”, is grammatically incorrect and this kind of expression in now becoming popular.

    Some language experts point out that language pollution must be done away With, which is an idea shared by myself and many others.
