【題目】 A computer program that could help catch and even translate messages from aliens in outer space has been developed by a British scientist.

If aliens are discovered one day, scientists fear their language may make it impossible to understand them. But John Elliott of Leeds Metropolitan University in Britain has come up with a program that can figure out the structure (結(jié)構(gòu)) of their language. He thinks that’s the first step in understanding what they are saying.

Dr Elliott’s program would compare an alien language to a database (數(shù)據(jù)庫) of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure. “Language has to be structured in a certain way, or it will be hard to use,” he told New Scientist magazine.

Research has shown that it is possible to know if a signal carries a language rather than a picture or music. Dr Elliott has gone a step further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr Elliott has set up a library of the sentence structures of 60 human languages.

If a message is received from outer space, it could be compared against this database. Scientists would then be able to see if it’s similar to any human language, or a mix of the languages.

However, Dr Elliott also said that in order to translate what the aliens are actually saying, it may still be necessary to have a “code (密碼) book”.

【1】Why did Dr Elliott come up with the program?

A.To learn more about outer space.B.To compare an alien language to human languages.

C.To develop a new language.D.To help translate messages from aliens.

【2】According to Dr Elliott, what’s the first step of understanding an alien language?

A.Coming up with a program.B.Knowing its structure.

C.Understanding aliens.D.Discovering aliens.

【3】What does Paragraph 4 mainly tell us?

A.Some necessary conditions for making the program work.

B.Dr Elliott’s findings about the differences between human languages.

C.Three important functions of the program.

D.The number of sentence structures of human languages.

【4】How does the program work when it receives a message from aliens?

A.Mix the message with 60 human languages.

B.Translate the message and send it to the database.

C.Pick out the sentence structure and translate it.

D.Compare the message to the database of 60 human languages.

【5】What can we infer from the passage?

A.Not all languages have their own structures.

B.To translate alien languages, there is much work to do.

C.The structure of alien languages is similar to that of human languages.

D.Alien languages are signals carrying pictures and music.

【解析】

文章大意：短文講了人們對外星人語言的研究，詳細的介紹了一種程序的應用情況。

【1】細節(jié)理解題。根據(jù)第二段句子“If aliens are discovered one day， scientists fear their language may make it possible to understand them． But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structureof their language． He thinks that's the first step in understanding what they are saying．”如果有一天外星人被發(fā)現(xiàn)，科學家們擔心他們的語言可能讓他們理解他們。但是英國大學的艾里爾特想出了一個程序來確定他們的語言的結(jié)構(gòu)。他認為這是第一步。了解他們在說什么�？芍獮榱藥椭g外星人的信息。故答案為D。

【2】細節(jié)理解題。根據(jù)第二段句子“If aliens are discovered one day， scientists fear their language may make it possible to understand them． But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structureof their language．”如果有一天外星人被發(fā)現(xiàn)，科學家們擔心他們的語言可能讓他們理解他們。但是英國大學的艾里爾特想出了一個程序來確定他們的語言的結(jié)構(gòu)。他認為這是第一步�？芍酪粋�結(jié)構(gòu)。故答案為B。

【3】段意歸納題。根據(jù)第四段內(nèi)容及其句子“Research had shown that it is possible to know if a signal（信號）carries a language rather than a picture or music． Dr．Elliott has gone a step further by finding a way to pick out what might be words and sentences．”研究表明，有可能知道一個信號是否攜帶語言而不是圖片或音樂。埃利奧特博士找到了一種方法來找出可能是單詞和句子的步驟。可知第四段主要告訴我們使程序工作的一些必要條件。故答案為A。

【4】細節(jié)理解題。根據(jù)第四段句子“Because languages have different word orders， Dr．Elliott has set up a library of the sentence structures of 60human languages．”因為語言有不同的詞序，埃利奧特博士建立了一個詞庫。60種人類語言的句子結(jié)構(gòu)庫。“If a message is received from outer space， it could be compared against this database． Scientist would then be able to see if ti's similar to any human language， or a mix of the language．”如果從外層空間收到消息，可以將其與此數(shù)據(jù)庫進行比較。然后科學家就能知道ti是否與任何人類語言相似，或者是語言的混合�？芍獙⑾⑴c60種人類語言的數(shù)據(jù)庫進行比較。故答案為D。

【5】細節(jié)推理題。根據(jù)這篇文章內(nèi)容及其最后一段句子“However， Dr．Elliott also said that in order to translate what the aliens are actually saying， it may still be necessary to have a code book”然而，埃利奧特博士還說，為了翻譯外星人實際上在說什么，也許仍然需要有一本代碼書�？芍g外星人的語言，有很多工作要做。故答案為B。

【題目】閱讀理解七選五。根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

When we eat potato chips, it’s often difficult to stop until the bag’s empty. We open a bag of chips , and before we know it ,they’re all gone . So why can’t we control ourselves when it comes to eating this salty snack?【1】

Scientists found that certain neurons(神經(jīng)元) can make us want to eat salt. The neurons take note of whether our bodies are short of sodium(鈉)，the main part of salt .【2】

Scientists did experiments on mice. They found that when mice lack sodium, their body produces a chemical.【3】 More research showed that adding salt to meals makes people enjoy their food more, which may cause us to continue eating even if we’re full. Scientists asked healthy people to eat the same food for lunch for four weeks.【4】 At the same time, the scientists measured how much these people ate. They also asked the people how they felt about each meal. For example, If they felt happy or were still hungry after eating . The results showed that salt made people eat out 11 percent more food than usual.【5】 “But when we add salt to that food , all of a sudden those controls are gone,”researcher said.

So the next time you finish a whole bag of chips to yourself, don’t feel so bad about it – just blame it on your brain.

A. Eating less salt can be difficult at first.

B. Then, they send signals to our brain to encourage us to eat more salt.

C. When eating low-salt meals, they had better control over how much they ate.

D. It could have something to do with our brain.

E. Eating too much salt can lead to health problems.

F. This chemical then makes the neurons active.

G. Each week , the number of salt in the food was changed.
