阅读理解。     Science Daily (Apr. 27, 2008)-- Dutch ecologist Roxina Soler and her colleagues have
discovered that subterranean (地下的) and aboveground 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. This way, aboveground insects are warned that the
plant is already "occupied".
     Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean
root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant,
which warn the aboveground insects about their presence. This messaging makes it possible for
spatially-separated insects to avoid each other, so that they do not compete for, the same plant.
     In recent years it has been discovered that different types of aboveground insects develop slowly
if they feed on plants that also have subterranean insects and "vice versa (反之亦然). It seems that a
mechanism (机制) 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 the natural enemy of caterpillars (毛虫). Parasitic wasps (寄生蜂) lay their eggs inside above
ground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more
insects for their eggs.
     The communication between subterranean and above- ground insects has only been studied in a
few systems. It is still not clear how widespread this phenomenon is, say the researchers.1. How do subterranean and aboveground insects communicate with each other?A. By sending signals through the leaves.    
B. By giving off particular smells.
C. By making soft and beautiful sounds.    
D. By the signals sent by parasitic wasps.2. After finding a plant occupied by root-eating insects, aboveground insects will usually ________.  A. send out warning signals        
B. choose to leave the plant
C. compete for the same plant      
D. fight with the root-eating insects 3. Aboveground insects will develop more quickly if their food plants ________.   A. are often visited by parasitic wasps    
B. are not occupied by mot-eating insects
C. have more green leaves            
D. have more subterranean insects4. What does the underlined part "a third party" in Paragraph 4 include?  

A. Aboveground insects.  
B. Root-eating insects.
C. Caterpillars.        
D. Parasitic wasps.

5. What would be the best title for the passage?   A. Communication between different insects
B. How do animals avoid competition?
C. Insects use plants as telephones
D. When plants have subterranean residents

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余项。    Does this situation seem familiar to you? Your English is progressing well, the grammar is now
familiar, the reading comprehension is no problem, and you are speaking quite fluently.  1  
    First of all, remember that you are not alone. Listening is probably the most difficult job for almost
all learners of English as a foreign language.   2  what you need to do is to find listening resources. The
Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia.
com. The Real Player allows you to use the Internet like a radio station.
    Once you have begun to listen on a regular basis, you might still be frustrated(受阻)by limited
understanding  3  
    Here is some of the advice I give my students:
    Accept the fact that you are not going to understand everything.
    Stay relaxed when you do not understand, and try listening to the material for more times.
    Do not translate everything into your native language .
      4  Don"t concentrate on detail until you have understood the main ideas.
    Listen to something you enjoy.
    I remember the problems I had in understanding spoken German when I first went to Germany. In
the beginning, when I didn"t understand a word, I insisted on translating it in my mind.   5  Then, after
the first six months, I discovered two extremely important facts; Firstly, translating creates a barrier
between the listener and the speaker. Secondly, most people repeat themselves constantly. By remaining
calm, I noticed that even if I didn"t pay much attention I could usually understand what the speaker had
said.
    A. What should you do?
    B. But listening is a problem for most of the beginners!
    C. However, after several weeks, I got used to the grammar rules
    D. The most important thing is to listen as often as possible.
    E. This method usually resulted in confusion.
    F. Listen for the general idea of the conversation.
    G. But you can"t follow a native English speaker at all!

     Today, there are many avenues open to those who wish to continue their education. However,
nearly all require some   1    in one"s career in order to attend school full time. Part-time education,
that is, attending school at night or for one weekend a month, tends to drag the    2   out over time
and puts the completion of a degree program out of reach of many people.    3   , such programs
require a fixed time commitment which can also impact   4    on one"s career and family time.
    Of the many    5   to teaching and learning, however, perhaps the most flexible and accommodating
is that called distance learning. Distance learning is an educational method, which allows the students
the    6   to study at his or her own pace to achieve the   7    goals, which are so necessary in today"s
world. The time required to study may be set aside at the student"s convenience with due    8   to all
life"s other requirements. Besides, the student may   9    in distance learning courses from virtually any
place in the world, while continuing to pursue their chosen career. Tutorial assistance may be   10 
through regular airmail, telephone, fax machine, teleconferencing and over the Internet.
    Good distance learning programs are characterized by the inclusion of a subject   11    tool with
every subject. This precludes(排除) the requirement for a student to travel away from home to take
a test. Another characteristic of a good distance-learning program is the   12    of the distance-learning
course with the same subject materials as those students taking the course on the home campus. The
resultant diploma or degree should also be the same whether distance learning or on-campus study is e
mployed.
    In the final analysis, a good distance learning program has a place not only for the    13   students but
also the corporation or business that wants to work in partnership with their employees for the educational
benefit, professional development, and business growth of the organization.    14   distance learning
programs for their employees gives the business the advantage of retaining(保留) career-minded
people while    15   to their personal and professional growth through education.

    Read the passage carefully. Then answer the questions or complete the statements in the fewest
possible words.
    When the Internet powerhouse Yahoo wanted to teach ethics(道德标准) to its employees, it
faced a challenge familiar to multinational companies.
    Yahoo employs nearly 14,000 people at 25 sites worldwide. They would feel bored at sitting
down in front of a dated video in which actors with 1980s haircuts tell them what to do. So it hired
a company calledThe Network <> to design a game. In the game, the truck
where Yahoo was founded traveled the world, turning into a boat and a helicopter along the way as
it visited some of Yahoo"s foreign offices. Participants play in game show-like scenarios(场景) that
quiz them about conflicts of interest and doing business fairly. And employees note: Yahoo is tracking
how well they do.
    Such activities draw more enthusiastic participation and teach more effectively than traditional
methods. They are described as alternative-reality games (ARGs), involving both interactive and
real-world elements. Besides teaching employees, ARGs have also been used in many areas for a
number of different purposes.
    From a marketing perspective, a number of very successful ARGs have been written as a way to
build product awareness. A very popular ARG called I Love Bees was produced to market the
2004 video game Halo 2 <>. At its height, I Love Bees received between
two to three million unique visitors over the course of three months.  
    ARGs are more than just a fun way to learn. They have also been used to solve real world
problems. An ARG called World Without Oil <> was created to obtain
collective input from players about dealing with the world"s dependency on oil. World without Oil
simulates(模拟) the first 32 days of a global oil crisis and anybody could play by creating a personal
story that recorded the imagined reality of their life in the crisis. World Without Oil"s success on a
small budget has opened the door for similar games to engage mainstream Internet users with climate
change, education reform, governmental policy and other timely, vital issues.
    (Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
1.What challenge did yahoo face in teaching ethics to its employees?
2.In the game designed for yahoo, participants had to answer questions about ________.
3.What are the three major functions of ARG mentioned in the passage?
4.The success of World Without Oil <> suggests that ARGs can ________.
