Science Daily -------- Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean（地下的）and above ground herbivorous（食草的）insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. Thus, aboveground insects are warned that the plant is already “ occupied”.
In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa（反之亦然）. It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition.
Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely caterpillars（毛虫）. Parasitic wasps（寄生的黄蜂）lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, The communication between subterranean and aboveground It is still not clear how widespread this phenomenon is.
This research was carried out at the Netherlands Institute for Ecology by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. was funded by the Free Competition of NOW Earth and Life Sciences.

It’s 5:00 in the morning when the alarm (闹钟) rings in my ears. I get out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD Insanity. Sweat pours down my face and into my eyes. My heart races as I force my body to finish each movement. As I near the end of the exercise, I feel extremely tired, but a smile is on my face. It’s not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother’s chocolate cake. They raise their eyebrows, surprised by my “no thank you,” or by my choice to have a salad. Over the years, I have learned it’s okay to just say “no.” I shouldn’t feel sorry for refusing food that I don’t want to eat.
So what drives me to get out of bed at 5:00 a.m.? What gives me the reason to just say no to ice cream? Commitment. A commitment to change my life with a way that reduces daily worry, increases self -confidence and energy, extends (延长) life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It’s through commitment and sweat that I can make a difference within myself inside and out.Why is there a smile on the author’s face in the morning?

Mobile Phones in Schools

She said some schools had tried to forbid mobile phones to be used at school. Some parents felt unhappy because they couldn’t get in touch with their children. Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school office. They also said there were many reasons why the students should not have mobile phones at school: they were easy to lose and were a distraction from studies.

Although computers used to be large, expensive and difficult to use, they have been made smaller, cheaper and easier to use. As a result, more people have been buying computers for their homes and businesses. They are used to record information and make difficult things easy.
Let’s look at some of the many ways computers may affect(影响) your life.
Want to get the best treatment at hospitals? Your doctors at hospitals have been greatly helped by computers to get information about patients. It is possible for doctors from different hospitals to read the records of patients, discuss them and make decisions on the best treatment. It would, at one time, take them hours and days to do so.
Want to talk to your friends both at home and abroad? Then it’s necessary to connect your computer to the Internet and set up your own e-mail letter box. You can then collect and send mails in seconds. It will be a waste of time and money to post your letters.
Want to get advice from Michael Jordan on how to play basketball like a NBA super star? Now it is possible to find out what it is on the Internet.
But if you think you have entered the information age because you have the chance to use the Internet, you are wrong. The reason is quite a simple one:over 98 percent of the information on the Internet is in English. The information on-line won’t be helpful to you unless you can use English freely.
| A．small | B．easy to use |
| C．cheap | D．dear |
| A．get information about patients |

| B．put up a letter box in front of the house |
| C．go to the post office to post letters |
| D．all of the above |
| A．治疗 | B．对待 | C．药品 | D．病房 |
| A．Modern Computers | B．Computers In Your Life |
| C．Learn English Well | D．Why Don’t You Buy A Computer? |

The traditional distinction between products that satisfy needs and those that satisfy wants is no longer adequate to describe classes of products. In today’s prosperous societies, the distinction has become unclear because so many wants have been turned into needs. A writer, for instance, can work with paper and pencils. These are legal needs for the task. But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want.
In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main classes are convenience goods and shopping goods. Two lesser types are specialty goods and unsought(主动提供的) goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France (wine, for example) should be a specialty goods in the United States.
People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae(圣代) on a hot day. Or they may be purchased as emergency items.
Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores before making a decision. Buying an automobile is often done this way.
Shopping goods fall into two classes; those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially different include clothing, furniture, and dishes. Quality, style and fashion will either take precedence(优先) over price, or they will not matter at all.It can be learned from the first paragraph that ______.
| A．a writer needs a word processor |
| B．needs and wants can’t be separated clearly |
| C．the way to distinguish the products is unimportant |
| D．a computer is a need rather than a want |
The example of wine is used to illustrate that ______.
| A．goods are classified differently in different countries |
| B．the types of the product lie on the people rather than its nature |
| C．Frenchmen often drink but Americans sometimes do |
| D．one product may belong to many types |
Staples are items that ______.
| A．are convenient to purchase |
| B．are purchased without enough thinking |
| C．people “want but don’t need” |
| D．people are in constant need of |

| A．consumers don’t care where to buy them |
| B．consumers spend much time searching for |
| C．satisfy similar needs of the consumer |
| D．can be found in nearly every shop |
