【题目】太阳大,地球小,太阳带着地球跑;地球大,月球小,地球带着月亮跑。重温童谣,结合所学知识,回答下面小题。

【1】童谣中涉及的天体系统层次共有

A.一个 B.两个 C.三个 D.四个

【2】假如人类移居月球生活,下列可能发生在月球的现象是

昼夜现象 电闪雷鸣 朝霞、晚霞 日食、月食 行走如跳远

A.①② B.③④ C.④⑤ D.①⑤

【答案】

【1】B

【2】D

【解析】

试题分析:

【1】本题考查天体系统的层次。距离相近的天体因相互吸引和相互绕转,构成不同级别的天体系统,天体系统的层次为:最高一级为总星系(即目前所知的宇宙范围),第二级为银河系和河外星系(河外星系简称星系),银河系又向下分成第三级的太阳系及其他恒星系,太阳系向下分成最低一级的地月系和其他行星系。童谣中涉及的天体系统有太阳系、地月系。所以本题选择B选项。

【2】本题考查宇宙环境。月球表面无液态水,所以不会出现电闪雷鸣的天气现象,不会出现朝霞和晚霞;位于月球上,不能看到月食现象。月球是不透明球体,故有昼夜现象;月球质量小,引力小,所以人类在月球上行走如跳远。所以本题选择B选项。

【题目】C

Many of us still tend to think that emotions can affect reasonablethought,and sometimes land us in trouble.But in recent years psychologists have taken quite a different view.Keith Oatley,Professor of Psychology at Glasgow University,is involved in the research which shows the fundamental importance of emotions.

He believes we_are_very_ambivalent_about_them:we think of our emotions as being unreasonable,but we also consider them as essential to being human.For example,Mr Spock,a character in the television series Star Trek,is superintelligent and he has no emotions at all.However,he is never made captain of the spaceship.Maybe,this is because Mr Spock is not the kind of person you can share your feelings with—a person who shows his emotions.

As Professor Oatley points out,our emotions have very important functions,for example,fear.If we cross the road and a car approaches,we usually stop moving or step back.We stop what we are doing,check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which,on average,help preserve our safety.

On the other hand,if things are going well and small problems come up,we find we can solve them with the resources we have to hand.As a consequence,we tend to feel happy and usually continue doing the job.

Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person,or to try harder,and so on.

Professor Oatley believes emotions generally ocur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else,while with happiness they “suggest” we continue what we are already doing.

【1】What’s Keith Oatley’s opinion about emotions?

A.They affect reasonable thought.

B.They get us into trouble.

C.They are helpful to us.

D.They are reasonable.

【2】What does the underlined part “we are very ambivalent about them” in Paragraph 2 mean?

A.We have contradictory feelings towards emotions.

B.We have similar ideas of emotions.

C.We are quite clear about emotions.

D.We can do nothing about emotions.

【3】It can be inferred from the passage that________.

A.we must control our emotions in daily life

B.emotions play a more important part than we realize

C.positive emotions such as love and joy are good for us

D.negative emotions make us continue what we are doing

Researchers in China and the United States have developed a new cataract(白内障)treatment with cells that has restored vision in babies in a trial and may eventually be used in adults.

The treatment- by doctors and staff members at the University of California, San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9 edition of the scientific journal Nature.

A cataract is a clouding of the normally clear lens(晶体)of an eye. Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one. The new operation has been tested in animals and during a small, human trial. It resulted in fewer complications(并发症)than the current harmful operation, and in regrown lenses with superior visual function in all 12 of the baby cataract patients who received the procedure.

A congenital cataract- lens clouding that occurs at birth or shortly after- is important cause of blindness in children. In the new research, Kand Zhang, head of ophthalmic genetics at US San Diego’s Shiley Eye Institute, and his colleagues relied on the regrown potential of endogenous(同源的)stem cells.

According to Zhang, endogenous stem cells are different from other stem cells that are typically grown in a laboratory, transplanted into a patient, and can have risks of immune(免疫的)rejection, infection or cancers. Zhang told CBS News, “We invented a new operation to make a very small opening at the side of a cataractous lens bag, remove the cataract inside, allow the opening to heal, and promote potential lens stem cells to regrow an entirely new lens with vision.”

The human trial involved 12 babies under the age of 2 who were treated with the new method, while 25 babies received thee standard operation care.. The latter group experienced a higher incidence of pos- operation danger, early- onset eye high blood pressure and increased lens clouding. The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure.

【1】What is the text mainly about?

A. The concept of the cataract

B. A new cataract treatment with stem cells

C. Bad effects of post-operation in the cataract

D. The reasons why the cataract comes into being

【2】Which of the following best describe the new cataract treatment according to the passage?

A. Convenient B. Comfortable C. Cheap D. Safe

【3】What can we learn about the new cataract treatment?

A. It has more risks

B. It may be used widely

C. It has been put into practice widely

D. It can only restore vision in babies

【4】What does the underlined word “congenital” in the fourth paragraph mean?

A. Born B. Strange C. Serious D. Dangerous.
