It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.
  The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.
  And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
The first paragraph tells us that _____.

A.all living things in nature depend on each other
B.everything in nature can’t exist without the help of man
C.man has known the importance of the balance of nature for a long time
D.no living thing can live naturally

In the second paragraph the examples given are used to prove that _____.

A.all forms of life belong to a system in which all the parts can be changed for one another
B.it is only during the last few years that man has generally known the balance of nature
C.there are some living things which can exist by themselves without change
D.we can’t change one form of life without destroying the balance of nature

The last paragraph suggests that in order to get his immediate benefits(利益) _____.

A.man is always anxious to control his activities within limits
B.man is always too eager in planning for distant future
C.man often fails to think about their future results of his action
D.man often feels that he will have to give up in despair

Which of the following is true according to the passage?

A.Cutting down woods does little harm to human beings.
B.Man has to pay much more attention to the future results of his present action.
C.Oxygen comes from forests.
D.The passage tells us to try our best to get as much as possible immediately.

The playwright George Bernard Shaw once said humorously, “England and America are two nations divided by a common language. If he were writing today, he might add ‘divided by a common technology--- e-mail’”.
Two completely different styles of e-mail have formed on either side of the Atlantic-Euromail and Amerimail. Americail is informal and chatty. It’s likely to begin with a “Hi” and end with a “Bye”. The chances of Amerimail containing a smiley face or an “xoxo” are disturbingly high. We Americans are unwilling to dive into the meat of an e-mail. We feel we have to first inform recipients (收信人) about our vacation on the island which was really excellent except the jellyfish were biting and the kids caught a cold, so we had to skip the whale watching trip, then about that investors(投资者)’ meeting in New York. Amerimail is a bundle of contradictions, casual and yet direct, respectful yet over proud. In other words, Amerimail is America.
Euromail is stiff and cold often beginning with a formal “Dear Mr. X” and ending with a simple “Sincerely”. You won’t find any mention of kids or the weather or jellyfish in Euromail. It’s all business. It’s also slow. Your correspondent might take days even weeks to answer a message. Euromail is exactly like the Europeans themselves.
Recently about 100 managers were asked on both sides of the Atlantic whether they noticed differences in e-mail styles. Most said yes. Here are a few of their observations:
“Americans tend to write (e-mail) exactly as they speak.”
“Why don’t you just call me instead of writing five e-mails back and forth?”
“Europeans are less interested in checking e-mail”.
“In general, Americans are much more responsive to e-mail—they respond faster and provide more information.”
So which is better, Euromail or Amerimail? I realized it’s not popular these days to suggest we have anything to learn from Europeans, but I’m fed up with an inbox filled with casual, barely meaningful e-mails from friends and colleagues. If the alternative is a few earnestly written, carefully worded bits of Euromail, then I say, “Bring it on.”
What did George Bernard Shaw mean by saying “England and America are two nations divided by a common language”?

A.There is sharp difference between England and America despite their common language.
B.Both England and America speak the common language, so they are much the same.
C.Either England or America is a divided nation, though they share a common language.
D.There is not much difference between British English and American English.

Which of the following is most likely to be the “meat” of an Amerimail?

A.The jellyfish were biting.
B.We had an excellent vacation on the island.
C.We were to attend the investors’ meeting in New York.
D.We had to skip the whale watching trip.

On receiving an e-mail, Europeans tend to __________.

A.respond to it immediately and earnestly
B.never respond to it all
C.respond by calling up their correspondent
D.take more time than Americans to respond to it

What are characteristics of Amerimail?

A.Stiff and cold
B.Casual and indirect
C.Informal and chatty
D.Formal and direct

We can conclude from the passage that __________.

A.the different e-mail styles do much harm to the relationship between the two sides on Atlantic
B.the writer doesn’t like either e-mail style as both have their own shortcomings
C.Euromail always impresses the writer as something more pleasant to read
D.Amerimail is more appreciated by the writer for being informative and casually written

Attitude isn’t quite everything when it comes to being successful, but attitude plays a part in every stage of your life. A poor attitude gets more people fired than any other single factor, and a good attitude gets people jobs and helps them keep those jobs more than any other factor.
Your attitude affects many people, from your family to the stranger on the street corner. Your attitude is particularly important when you face seemingly hopeless situations. Losing a job or a friend because of a poor attitude is unfortunate—especially because a bad attitude can be fixed.
You can find at least two ways to look at everything. A pessimist looks for difficulty in the opportunity, while an optimist looks for opportunity in the difficulty. A poet of long ago put the difference between optimism and pessimism(悲观主义) this way: two men looked out of the prison bars—one saw mud while the other saw stars.
Unfortunately, many people look only at the problem and not at the opportunity that lies within the problem. Many employees complain about the difficulty of their jobs, for example, not realizing that if the job was simple, the employer would hire someone with less ability at a lower wage. A small coin can hide even the sun if you hold the coin close enough to your eye. So when you get too close to your problems, to think objectively(客观地) about them, try to keep in mind how your vision(视觉)can be obstructed. Take a step back, and look at the situation from a new angle.
You can’t do anything to change the fact that a problem exists, but you can do a great deal to find the opportunity within that problem. You’re guaranteed a better tomorrow by doing your best today and developing a plan of action for the tomorrows that lie ahead. Just remember to maintain a positive mental attitude.
What does the author mean by saying the first sentence in Paragraph 1?

A.If you have a good attitude, you will be successful.
B.Your attitude makes a great influence on your life.
C.Your attitude has nothing to do with your success.
D.Your success is very important to your life.

In Paragraph 3, the writer shows us ________.

A.two ways to look at everything
B.the ways to look for opportunity
C.the explanation of pessimist and optimist
D.the ways to look out from prison bars

A team of researchers from Oxford University has demonstrated a self-driving car that is different from such cars being tested by Audi, Ford, etc. It’ s much cheaper because it’s based on off-the-shelf(现成的) technology and controlled by an ordinary iPad. Instead of using GPS to understand the location, the car learns routes when a person is driving, and then asks after it’s got it down, if the driver would like the computer to take over.
As time passes, it’s becoming very clear that people believe computers would be better drivers than humans. This has been proven by extensive research that indicates that computers are able to react more quickly to driving conditions, make smarter decisions, don’t take risks, and don’t make mistakes in concentration. They don’t drink either, of course, which means accidents due to drunk driving could be reduced dramatically if the computer could take over when someone needs to get home from the bar. And the team says drivers don’t need their cars to know everything about every road, condition or possible danger. Instead, they just need to know how to get from one point to another, and to do a good job of it when asked.
To that end, the researchers have added cameras, lasers, a central computer to process information and a regular iPad. In practice, the car would learn how to get to and from places that the driver frequents, such as their work place, the local pub or grocery store. Once it has it down, the computer asks the driver if they’ d like a rest. If so, they simply tap the iPad, and the car takes over.
It’ s very simple and doesn’t require nearly the same number of devices as those being tested by other car companies. The researchers say people might be able to get the total price of the system below a hundred dollars. And of course, the iPad can be lifted out and carried away for other purposes when not being used as a driver assistant.
The car tested by Oxford University are different from others in that they ________.

A.use available low-cost technology
B.depend on GPS to understand the location
C.can choose the places for their owners to visit
D.can develop a good relationship with their owners

Computers are believed to be better drivers than humans mainly because they ________.

A.are more likely to take risks
B.are more familiar with every road
C.become more skilful at avoiding dangers
D.can respond to new situations more quickly

We can infer from the passage that the iPad __________.

A.cannot be removed from cars when it’s not used
B.has replaced cameras, lasers and a central computer
C.needs to be specially designed for a self-driving car
D.acts as a tool for drivers to control their self-driving cars

Every year, I tell my sons what I'd like for Mother's Day: a letter, something written from the heart and offered freely rather than bought from a store and wrapped neatly. I don't always get my wish, nor do I always take the time to write to my own mother.
This year, my boys will be in two different states on Mother's Day. My mom and dad will be away together, and I'll be driving home from a writer's workshop in Massachusetts. Thinking of the fact that many friends have already lost their mothers and that a few have lost children, I am deeply grateful that what separates us, for now at least, is merely distance. It won't always be so, and there is no way to prepare for that fact other than to appreciate the moment that is. My sons know that they can please me on Sunday with a phone call or an e-mail, and that is enough as I love their words. The very best gift they can possibly give me is their own happiness, the very fact of their busy, full and well-lived lives.
Still, knowing that my years of staying with my sons are over, I do feel doleful. The truth is, I miss being the center of the universe to two little boys. And this holiday can be a bit painful.
I wonder if my own mother ever felt nostalgic (怀旧的,乡愁的) for the passing of my childhood. I wonder if she realizes that she is still at the center of my universe and always has been. I don't often pause to think about it, but of course she is the one who has been right there, at my side from the moment I drew my very first breath. How to ever fully appreciate the woman whose presence and love and example have shaped me into the adult I am? How to describe even a small part of the sharing, sacrificing, and support she has given me over the years?
The author mainly wants to tell us through the first paragraph that_______.

A.she hopes to get her son's letters very much
B.her sons don't often write to her on Mother's Day
C.Mother's Day is the very date that she longs for most

A.her sons don't live far away from her home

C.her parents are coming to her house to spend Mother's Day
D.her sons can please her on Sunday with a phone call

I decided to cut my front lawn (草坪) today, especially since I live on a main street downtown with lots of traffic. I finished mine and decided to cut my neighbor — Joan’ grass while I was good at it. She is a sweet person who has gone through some trying times in the last year. Her brother passed away because of cancer last year, and her sister (who lives with her) was mentally challenged — yet so sweet!
It was a difficult time with physical and mental challenges that led her employer in our local hospital to let her go after 25 years of service! Lastly, my neighbor Joan, who is a nurse in our local hospital was diagnosed with esophageal(食道) cancer in December. She went through radiation and a long recovery — but thankfully she is in remission(缓解).
Anyway, in short I was leaving my house this afternoon and she stopped me to thank me for cutting her grass. She told me her dad passed away on Friday and she just arrived home from the funeral service, so she didn’t know when she would have time to cut her grass. So, when she arrived home and saw it cut she was more than happy and grateful! I said to her, "You are welcome.It’s just a small act of kindness for a neighbor."
I did it for exercise and pleasure, not knowing it meant more to her than just doing a neighbor a favor!
Although a lot of unfortunate matters happened to Joan, she is still.

A.pessimistic B.optimistic
C.depressed D.disappointed

What’s the meaning of the underlined word "trying" in the first paragraph?

B.She feels only happy.
C.She feels very happy and thankful.
D.She feels easy.
