9．Harvard researchers have created a tough，low-cost，biodegradable （可生物降解的） material inspired by insects'hard outer shells．The material's inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic．The material，made from shrimp （'虾） shells and proteins produced from silk，is called"shrilk．"It is thin，clear，flexible and strong．
A major benefit of the material is its biodegradability．Plastic's toughness and flexibility represented a revolution in materials science during the 1950s and'60s．Decades later，however，plastic's very durability （耐用性） is raising questions about how appropriate it is for one-time products such as plastic bags，or short-lived consumer goods，used in the home for a few years and then cast into a landfill where they will degrade for centuries．What is the point of making something that lasts 1，000years？
Shrilk not only will degrade in a landfill，but its basic components are used as fertilizer（肥料），and so will enrich the soil．
Shrilk has great potential，the inventors said．Materials from which it is made are plentiful in nature，found in everything ranging from shrimp shells，insect bodies to living plants．That makes shrilk low cost，and its mass production possible should it be used for products demanding a lot of material．
Work on shrilk is continuing in the lab．The inventors said the material becomes flexible when wet，so they're exploring ways to use it in wet environments．They're also developing simpler production processes，which could be used for non-medical products，like for computer cases and other products inside the home．They're even exploring combining it with other materials，like carbon fibers，to give it new properties．
49．Paragraph I of the passage is mainly about shrilk'sC．
A．remarkable designB．interesting name
C．major featuresD．basic elements
50．What has become a concern about plastic？A
A．Using it properly．
B．Producing it cheaply．
C．Developing its properties quickly．
D．Evaluating its contributions fairly．
51．According to the inventors，shrilk has great potential partly becauseD．
A．it can help plastic degrade
B．it can be found in living things
C．its mass production has been realized
D．its raw materials are abundant in nature
52．Which of the following can be the best title for the passage？D
A．Recent Progress in Environmental Protection
B．Benefits of Insects in Scientific Research
C．The Harm of One-time Products
D．A Possible Alternative to Plastic．

6．A branch of computer science called artificial intelligence uses programs that help solve problems by using human knowledge and experience．Artificial intelligence systems are also called expert systems，which enable computers programmed with great amounts of information to think about many possibilities such as diseases that certain symptoms （症状） could indicate and make a decision for tile treatment．
Computers are used in teaching as well．Programs that perform computer-aided instruction （CAI计算机辅助教学） are designed to help students at all levels，from elementary school to the university level．The student sits at a computer terminal （终端）．The terminal's screen displays a question for the student to answer．If the answer is wrong or incomplete，tile computer may ask the student to try again．It then may supply the correct answer and an explanation．CAI is also used in some adult education programs and as part of the employee training programs of some business companies．
One of the most important uses of computers is to communicate information over long distances．They can send information to each other over telephone lines．As a result，computers keep banks，newspapers，and other institutions supplied with up-to the minute information．A computer network consists of many computers in separate rooms，buildings，cities，or countries，all connected together．Computer networks allow people to communicate by using electronic mail a document typed into one computer and sent to an-other．Such
document generally travel in only a few minutes，even if they are being sent over a long distance．
The computer's ability to share information with other computers over a network linked by telephone lines is a major revolution in telecommunications．The Internet，an international network of computer networks，has spread out since the early 1990's．The Internet began as a US network of scientific and military computers in the 1960's．Now it is an international system for sending and receiving electronic mail，software，and electronic documents and picture files all over the world．The Internet has already cut the cost of long-distance communications for many people．In the future it will completely change the way people work．With the Internet，increasing numbers of people can work at home instead of in their office．
Computers and their programs are the most complex devices in human history，and probably the most useful．Modern industrial societies now depend on them．As computers become more powerful and widespread，computer education must continue to increase also．
60．From the first paragraph we get to know that artificial intelligence systemsD．
A．are beyond scientists'control       B．will take the place of doctors
C．will take the place of scientists      D．are under scientists'control
61．If you use E-mail to communicate with your friends，you canA．
A．exchange information without paper    B．talk with your friends freely
C．talk with your friends face to face      D．exchange information without computers
62．The phrase"up-to-the-minute"in the third paragraph meansB．
A．shortest    B．latest       C．longest    D．easiest
63．What is the main idea of this text？C．
A．Computers Are Dangerous         B．Computers Are Clever
C．Computers Are Useful             D．Computers Are Interesting．

13．Little Tommy was doing very badly in math．His parents had tried everything-tutors，cards，special learning centers-in short，everything they could think of．Finally they took Tommy to a catholic（天主教的） school．
After the first day，little Tommy came home with a very serious look on his face．He didn't kiss his mother hello．Instead，he went to his room and started studying．Books and papers were spread out all over the room and little Tommy was hard at work．His mother was surprised．She called him down to dinner and as soon as he finished eating，he went back to his room，without a word．In no time he was back hitting the booksas hard as before．This went on for some time，day after day while the mother tried to understand what was happening．
Finally，little Tommy brought home his report card．He quietly put it on the table and went up to his room and hit the books．His mom looked at it and to her surprise，little Tommy got an A in math．She could no longer hold her curiosity．She went to his room and asked，"Son，what was it？Was it the nuns（修女）？"
Little Tommy looked at her and shook his head，"No．"
"Well then，"she asked again，"WHAT was it？"

3．-How many people attended his wedding party？
-There are ______ 500guests．I can't remember exactly．（　　）

10．Michelle，who visited China in March，is ______ to bridge a better understanding in cultures of the two nations．（　　）

7．Aside from doing schoolwork and studying，American students must also participate in various extra-curricular activities．Many students get involved in their communities by doing volunteer work at various local organizations．In fact，the school I attend even requires students to perform a certain number of hours of volunteer work per semester．It is part of our study hall（自修课） grade，as well as a graduation requirement．
There are many places to do volunteer work in the community．Some of my classmates volunteer at the local animal shelter，the community table （which provides free meals for needy families），charity（慈善） stores，and many others．Finding a suitable place to volunteer usually depends on what's available，as well as personal interests．For example，a friend of mine who enjoys swimming volunteers at the recreation center to teach young children how to swim．
With all these options out there，I ended up doing most of my volunteer work at a school library and a non-profit bookstore called Friends of the Library．This bookstore sells donated books at cheap prices，and all the profits made are donated to the local library．
I thought it was very fitting that I do my volunteer work at a library and a bookstore，because reading has always been very important to me．I love working in the bookstore now，because every sale we make helps our public library expand，and gives it the funds needed to purchase new books．
I think everyone should have the opportunity to read，and that we each should do our part to help those who don't have the chance．There is a charity event，called One Book for A Window of Opportunity，in which Chinese students can donate a book to the children of the poor village Fangmaping．They don't have a lot of resources，so reading can be a challenge．To find out more about this event，please visit：http://bbs．enfamily．cn/thread-739278-1-1．html．
