Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked．
Perhaps the best answer lies in our genetic makeup（基因构成） as human beings．What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of' a species, the better its chance of' survival． Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible． Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for． Without knowledge, we may be completely destroyed by the danger． With knowledge, we can lessen its effects．
Exploration also allows minerals and other potential（潜在的） resources to be found．Even if' we have no immediate need of them, they will perhaps be useful later． Resources may be more than physical possessions． Knowledge or techniques have been acquired through exploration．The techniques may have medical applications which can improve the length or quality of our lives．We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems． Even non-stick pans and mirrored sunglasses are by-products （副产品） of technological developments in the space．
While many resources are spent on what seems a small return, the exploration of' space us．While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers． The danger exists, but knowledge can help human being to survive． Without the ability to reach out across space, the chance to save ourselves might not exist．
While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets． It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future．

“Grandma, Grandma, tell us a story ! ”Four darling children sat by my feet, looking up at me expectantly． Suddenly, we were interrupted clapping．“Terrific, ” the director said, stepping up the stage from the aisle（过道）．“Except, could you kids face the audience a bit more? ”

“Fine !” she answered． Just then, someone else walked up and asked the girl her name．
I wasn't sure I heard the girl's answer correctly． But it made me ask her another question．“What's your mother's name? ”
She told me, I was still in shock．“And what's your father's name? ”I asked． She told me．It was my son．

You’re standing in the dairy section at the grocery store, searching for your favorite brand. Suddenly, you catch a smell of chocolate cookies. You forget about dairy and head for the bakery (烘烤食品) section. Guess what? You just walked into an odor (气味) trap (陷阱)! The odor was cooked up by scientists in a lab.
For years, scientists have been studying the special powers of smell. They found that more than our other senses, smell changes our mood and helps us remember things.
So companies have begun spending thousands of dollars to scent (使充满香味) entire stores. Artificial (人造的) scents are being used to lead customers by the nose. These smells help to get people inside and put them in the mood to buy. They even make customers remember the store later, so they’ll come back for more. Also, many companies have smartly made use of product smells. A company added lemon fragrance to its dish cleaner. They wanted people to think the soap contained “natural” cleaners. It worked!
New uses for smells are being created every day. One bank, for example, gives customers coupons (优惠券) advertising car loans (贷款). To get people to take out a loan, bank officials hope to coat these coupons with the fresh leather smell of a new car. In Australia, telephone offices are putting sweat odor on unpaid bills. Since some people sweat when they’re scared, this smell might remind them of when they were frightened. And they’ll pay the bills right away!
What lies ahead for our noses? Smell scientists are working on some pretty far-out ideas. Would you believe TV sets that produce smells? Or how about scent diets? Certain food smells will fool your stomach into thinking it’s full. Alarm clocks will scent your bedroom with a strong pleasant smell designed to wake you up. Scientists are even working on ways to keep garbage from smelling. Researchers expect scents to help students make more sense of what they’re learning.
And just think. Someday soon, even your homework may smell nice!
How do sales methods affect customers in the stores?

A．They change customers’ preferences.

B．They persuade customers to use credit cards.

C．They make customers avoid bad and unsafe products.

D．They influence customers to make unplanned purchases.

Why do telephone offices put sweat odor on unpaid bills?

A．Because the sweat odor is a reminder of terrifying experience.

B．Because the sweat odor can change people’s attitude.

C．Because most people don’t think much of sweating.

D．Because many people dislike paying bills.

What does the author mean by saying “Someday soon, even your homework may smell nice!”?

A．Students would benefit more from smell research.

B．Students would be more willing to do homework.

C．Smell research would develop beyond our imagination.

D．Smell research would make great differences to our life.

Why does the author write this passage?

A．To encourage the store owners to use smells.

It’s really true what people say about English politeness: it’s everywhere. When squeezing (挤过去) past someone in a narrow passage, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles, and here are some more polite ways of interacting (交往) with people in UK.
People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize (批评) others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter are a bit tightfisted.
What is the author’s attitude towards English politeness?

A．He thinks it is unnecessary.	B．He thinks little of it.
C．He appreciates it very much.	D．He thinks it goes too far.

What can be inferred from the passage?

A．German men never treat a woman to dinner.

B．The author think it’s unnecessary to say “thank you” to the bus driver.

C．In Germany, employers often say “thank you” to employees for their job.

D．Germans think it is unnecessary to thank workers because payment is enough.

C．are as generous as English men

D．are unwilling to spend money for women

Whether they’re project documents, trade journals, blogs, business books or ebooks, most of us read regularly as part of our jobs, and to develop our skills and knowledge.
But do you ever read what should be a useful document, yet fail to gain any helpful information from it? Or, re-read something several times to get a full understanding of the content? If so, look at the following strategies (策略) that will help you read more effectively.
●Think About What You Want to Know
Before you start reading anything, ask yourself why you’re reading it. Are you reading with a purpose, or just for pleasure? What do you want to know after you’ve read it? Once you know your purpose, you can examine the resource (资源) to see whether it’s going to help you.
Ask yourself whether the resource meets your needs, and try to work out if it will give you the right amount of knowledge. If you think that the resource isn’t consummate, don’t waste time reading it.
●Know How Deeply to Study the Material
Where you only need the shallowest knowledge of a subject, you can skim material. Here you read only chapter headings, introductions, and summaries.
If you need a moderate (中等的) level of information on a subject, then you can scan the text. This is when you read the chapter introductions and summaries in detail. You can then speed read the contents of the chapters, picking out and understanding key words and concepts.
Only when you need full knowledge of a subject is it worth studying the text in detail (细节). Here it’s best to skim the material first to get an overview of the subject. This gives you an understanding of its structure, into which you can then fit the detail gained from a full reading of the material.
Why should we know our purpose before reading?

A．Because we can develop our skills and knowledge.

B．Because we can get a full understanding of the content.

C．Because we can avoid re-reading something several times.

D．Because we can check it out whether the material will be helpful.
