分析 本段是发生在Mike和Mary之间的一组对话.Mary询问Mike自己的新牛仔裤如何.Mike称赞Mary有眼光,会选衣服,而且Mike在对话中也请求Mary帮助参考去挑选一条时髦的牛仔裤.Mary则欣然同意了.

解答 31.A.考查对上下文的理解能力.根据空后内容They really suit you,Mary!和对方的答语可以判断Mike说了夸奖Mary的话,由此可知A选项内容符合语境,故选A.
32.F.考查对上下文的理解能力.从下文的答语I mean…they are very popular these days;可以判断Mike在问他是什么意思,选F.
33.E.考查对上下文的理解能力.根据上文You are great at keeping up with fashions.可知Mike认为Mary总是追时髦,所以判断空上内容是Mary对此做出的解释,选E.
34.B.考查对上下文的理解能力.前句Perhaps you can help me pick out a pair of jeans now,since you are an expert可知Mike提出请求,根据Mary的回答可知她愿意帮助他,B选项内容符合语境,选B.
35.G.考查对上下文的理解能力.在上句话since you are an expert.中Mike夸奖Mary是服装方面的专家,根据情理可知对于别人的夸奖应该表示感谢,选G.

点评 七选五阅读是完成性阅读,和完形填空很类似,不同的是一个选词,一个选句子.解题时,要注意上下文语境,充分考虑信息词(选项中和空格前后句子中相同或相近的词),选出最符合语境的句子.

7.Until last summer I had a very comfortable life:winter vacations skiing and summer cruises.My parents spent a lot of money on a private school,so they could get me into a competitive middle school.Everything was about tomorrow,next year,my graduation.We never had to worry about today.
Before last summer I never thought much about the people in the world who live day to day,every day,whose lives are controlled by poverty and hunger.Then I joined in a two-week intensive program.We lived in a"Tribal Village,"in a hot,dry open grassland in Arkansas,a state of the south-central United States.I am a tribal member in Mozambique,a country of southeast Africa.Every meal,I make the fire for my family,and feel the flames lick up my nostrils(鼻孔)as I blow to keep the fuel alive.I cook mush with vegetables.This is all my family is ever given.
I feed the hen and three rabbits their dinner.I grow attached to the rabbits,even though I know I shouldn't.I name them.I'm not getting enough to eat; it's time to decide whether or not to kill the rabbits.I feel pain but it's a privileged child's pain because I know I will soon be eating again.That's not true for a lot of other children around the world.
Growing up comfortably in the U.S.,I've never had to worry about my dinner,and even though this whole process was only a simulation,it changed my life.Now I believe in doing whatever I can to help find practical ways to defeat hunger.
So I've become president of Roots and Shoots,a group working to improve local environments for people and animals.I'm also working to create a program at my high school called the"Safe Passage"trip to help young people in the Guatemala City dump.And I've got plans to do more.
I'm often thinking of laboring in the hot sun and the millions who still do.Now,I try to live for today and stop worrying so much about the future.When I eat or feel full,I am grateful for this fortunate life and want to extend the same feeling to others.
I believe in offering help to those who need it.

4.So many of us hold on to little complaints that may have come from an argument,a misunderstanding,the way we were raised,or some other painful events.Stubbornly,we wait for someone else to reach out to us-believing this is the only way we can forgive or rekindle a friendship or family relationship.
A friend of mine,recently told me that she hadn't spoken to her son in almost three years.She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first.When I suggested that she be the one to reach out,she said,"I can't do that.He's the one who should apologize."After a little gentle encouragement,however,she did decide to be the first one to reach out.To her amazement,her son was grateful for her willingness to call and offered an apology of his own.As is usually the case,when someone takes the chance and reaches out,everyone wins.
Whenever we hold on to our anger,we turn"small stuff"(问题)"into  really"big stuff"in our minds.We start to believe that our positions are more important than our happiness.They are not.If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy.The way to be happy is to let go,and reach out.Let other people be right.This doesn't mean that you're wrong.Everything will be fine.You'll experience the peace of letting go,as well as the joy of letting others be right.
You'11also notice that,as you reach out and let others be"right",they will become less defensive and more loving toward you.They might even reach back.But,if for some reason they don't,that's okay too.You'll have the inner satisfaction of knowing that you have done your part to create a more loving world,and certainly you'll be more peaceful yourself.

29.The underlined word"rekindle"in Paragraph 1probably means"A".
A.recover     
B.develop     
C.accept      
D.replace
30.In the author's opinion,we hold on to our anger often because we thinkC.
A.we can turn small issues into big ones  
B.our positions are higher than others
C.our own opinions matter most         
D.others will be less defensive
31.The best thing to do after a quarrel is toD.
A.let go of our own rights     
B.realize that you are wrong.
C.expect others to give in     
D.apologize to others first.
32.What is the main idea of the passage?B
A.People should keep peaceful when facing small stuff.
B.Reaching out and apologizing wins one peace and happiness.
C.We should tell apart small and big stuff in our daily life.
D.It's necessary to enjoy our friendship and family relationship.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling Lausanne, Switzerland, demonstrated(展示)a small robotic wheelchair directed by a person's thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

"Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says.  "Our system allows disabled people to communicate with external world and also to control devices."

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
     Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices.  One example is this wheelchair."

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

1.BCI is a technology that can _________________.

A. help to update computer systems

B. link the human brain with computers

C. help the disabled to recover

D. control a person's thoughts

2.How did Tavella operate the wheelchair in the laboratory?

A. By controlling his muscles.

B. By talking to the machine.

C. By moving his hand.

D. By using his mind.

3.The team will test with real patients to                         .

A. make profits from them

B. prove the technology useful to them

C. make them live longer

D. learn about their physical condition

4.Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

B. New Findings About How the Human Brain Works

C. BCI Could Mean More Freedom for the Disabled

D. Robotic Vehicles Could Help to Cure Brain Injuries

Every time we get behind the wheel of a car, we pt our lives and the lives of others at risk. Self-driving cars are designed to reduce those risks by letting technology control our vehicles.

Accident rates for self-driving cars have been much lower than the rate, for human-driven cars. 1.

As humans, we can make moral choices in avoiding accidents. To avoid hitting a child, for example, human drivers might sharply turn a car away from the child even if others may be injured. 2. Researchers studied this issue. They have developed the Moral Machine website to help explore the choices self-driving cars should make.

3. . You are shown two possible traffic situations and you choose between them. An accident will take place. You choose how many living beings would be hurt or killed.

In one situation there may be a female doctor, a child, two dogs and a homeless person who would be killed. In the other situation, you might have two babies and a cat who would be killed. 4.

The Moral Machine website has many situations and many possible outcomes. When you click on the situation of your choice, it will be highlighted. 5. At the end of the situation, you are shown the results, based on the choices you made. The results show which character you were most likely to save and which character you were most likely to have die.

A. Who should those victims be?

B. Then the next situation appears.

C. You choose who lives and who dies.

D. You can use the Moral Machine to be the judge.

E. But what moral choices can self-driving cars make?

F. The Moral Machine website lets you choose how you would react in a collision.

G. Google’s self-driving car has had only 13 collisions after traveling 1.8 million miles.
