【3】Perhaps nanotechnology will have the biggest influence on medicine./ Perhaps nanotechnology will influence medicine most greatly.

【4】tiny machines

【5】Nanotechnology is a new type of science that will be widely used in many fields.

【解析】短文大意：本文主要講述了納米技術(shù)是一種新型的科學，將廣泛地應(yīng)用在許多領(lǐng)域，文中列舉了幾項納米技術(shù)將在生活中的應(yīng)用。

【1】a guitar一把吉他； so …that…如此…以至于，引導結(jié)果狀語從句；tiny形容詞，極小的； with the human eyes用人類的眼睛。所以本句翻譯為：一把吉他是如此微小，以至于你肉眼看不見（它）。

【2】原句意：納米技術(shù)是一種科學，這種科學可以用很小的方式處理事情。the science 作先行詞；用that或which作關(guān)系詞，并作定語從句的主語。所以答案為：Nanotechnology is the science that/which can deal with doing things in a very small way.

【3】perhaps副詞，也許；nanotechnology名詞， 納米技術(shù)；對醫(yī)學將有最大的影響have the biggest influence on/ influence medicine most greatly。本句描述將來的事情，故用一般將來時態(tài)表達：will+動詞原形。所以答案為：Perhaps nanotechnology will have the biggest influence on medicine./ Perhaps nanotechnology will influence medicine most greatly.

【4】根據(jù)上文Thousands or even millions of tiny machines can be sent into the human body with specific tasks.細讀可知，they指代tiny machines。所以答案為：tiny machines。

【5】根據(jù)短文大意可知，本文主要講述了納米技術(shù)是一種新型的科學，將廣泛地應(yīng)用在許多領(lǐng)域。所以答案為：Nanotechnology is a new type of science that will be widely used in many fields.

【題目】Where do you think people will live in the future? Can you predict people will work and live in the sea? But how will people go to work then? By submarine(潛水艇) . Some scientists believe that some day submarines will be as many as today's cars. A famous French diver says, “One day, man will walk on the ocean floor as they do on the street! "

If humans want to live in the sea, they have to solve a lot of problems first. Some of these problems, similar to those of living on the moon, are lack of oxygen（缺氧）and weightlessness （失重）. Many questions are hard to answer. For example, what will happen to our bodies if we Iive in the water for a very long time? Scientists are looking for answers.

Maybe in 50 years man will be able to live in the sea, away from the crowded and noisy cities on land. Man will find it fun and interesting to live in the sea.

And life in the sea is more comfortable. Don't you think so?

根據(jù)短文內(nèi)容 ,判斷下列句子正（T）誤（F）。

【1】Some scientists think people will have to live in the sea.

【2】If humans want to live in the sea, they have to solve a lot of problems first.

【3】Humans will have difficulty in breathing if they live in the sea.
