Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back.. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for
instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.The holly plant has more spines on the lower leaves because most animals________.
A.are not tall enough | B.like the lower leaves only |
C.are not clever enough | D.can get the lower leaves easily |
To defend themselves, oak trees use________.
A.chemical means | B.physical means |
C.bitter chemicals | D.sandy materials |
How does tobacco protect itself against an attack from a caterpillar?
A.Its leaves fight against the attack by physical means. |
B.Its roots send a messenger to discourage the caterpillar. |
C.Its roots increase the production of nicotine when it is attacked. |
D.Its leaves produce poisonous sand to drive the caterpillar away. |
What would be the best title for this passage?
A.Plants and Animals | B.How Plants Defend Themselves |
C.Attacks and Defenses | D.How Animals Eat Plant Leaves |
NEW YORK, May 19—A new, more destructive version of the “Love Bug ” virus is slowly spreading across the world, but so far the damage is small compared with its former version.
The new Love Bug virus creates disorder.
Richard Saunders of anti-viral firm Symantec said the virus only affected a dozen companies around the world.
“While it is a nasty virus, it’s not spreading anywhere near the rate Love But or (last year’s ) Melissa was spreading,” Saunders said.
“New Love” is similar in form to the Love Bug, which swept the world two weeks ago and caused more than $ 10 million in damages. But it’s much more destructive. The virus appears as an attachment to an e-mail whose subject begins with “FW”
If a user clicks on the attachment’s scroll-like icon(卷轴样的图标), every file on his hard drive is destroyed.
“Basically, it’s going to destroy your machine, ” said Eric Chine, chief researcher at Symantec’s anti-virus lad in the Netherlands.
The Love Bug only killed a small set of files, including graphic files. This virus even wipes out the Windows operating system.
Attorney General Janet Reno warned the public at a news conference today to be careful of any suspicious e-mail with attachments. “Do not open it, even it comes from a trusted source.” she said.
Don’t Open That Attachments.
Like the Love Bug, after the e-mail attachment is opened and the virus is carried out, New Love sends itself to everyone in a victim’s Microsoft Outlook address book. Fortunately for users, the lesson is the same as from the Love Bug: If you see a message with an attachment whose name ends in vbs, with a scroll-like icon, don’t click on the attachment. Also like the Love Bug, this virus only affects computers running Windows 98, NT 4.0 Windows 95 with Internet Explorer 5.0 and can only spread if users rely on a Microsoft Outlook address book for e-mail. Microsoft will soon give a fix for Outlook that warns people or suspicious attachments, the company said.
68. According to the passage, so far the new Love Bug virus _________.
A. has made the whole world disordered
B. causes more damages than other forms of virus
C. is the newest and spreading the fastest
D. has affected 12 companies around the world
69. Computer users are warned in this article _________.
A. not to suspect e-mails beginning with “FW” subjects
B. not to open attachment of doubtful e-mails
C. to stop using Microsoft Outlook address book
D. to examine the Windows Operating System carefully
70. It can be suggested from the passage that _________.
A. the mail sent by a friend is surely free of the virus
B. the Microsoft Company will take action against the virus
C. all computers running Windows 98 will be affected
D. the users can not find the way to deal with the Love Bug.
71. The author writes this passage in order to _________.
A. compare some types of virus
B. explain how the Love Bug is formed
C. tell the readers something about a new virus
D. remind computer companies to kill the virus
Yoga(瑜伽)is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. After a long time of practice yoga, you no longer just practice it — you love it.
Yoga becomes part of your physical life. Your body grows stronger, more toned(有弹性的), and more flexible as you move from one pose to another. I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight. “Rather than building muscles, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of KISS Guide to Yoga. “Because yoga helps maintain a balanced metabolism(新陈代谢), and it also helps to control weight. Additionally, yoga stretches muscles lengthwise, causing fat around the cells disappear, thus losing weight.”
I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need an increase in energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative(恢复体力的)poses.
Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves(使消除)stress and anxiety. I use yogic breathing on the tennis court, in the dentist’s chair, and when I’m stuck in traffic.
You should always leave a yoga practice feeling energized, but not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the poses by letting go of the tension.
64. What will be talked about if this passage continues?
A. Yoga is becoming part of your spiritual life.
B. Yoga is becoming popular all over the world.
C. The disadvantages of yoga.
D. Encouraging people to do yoga.
65. According to the second paragraph, yoga can help people ___.
A. grow tall B. lose weight C. be flexible in thinking D. make friends
66. Why does a person feel tired after yoga?
A. Because when practicing yoga, people will consume a lot of energy.
B. Because he or she surrenders to the poses by letting go of the tension.
C. Because yoga doesn’t benefit all the people.
D. Because he or she doesn’t do yoga poses naturally.
67. What would be the best title for this passage?
A. What’s yoga? B. How do I do yoga poses?
C. The benefits of yoga. C. The varieties of yoga.

第三部分阅读理解
阅读下面短文,从题后所给的A、B、C、D四个答案中选出最佳选项。
All her life, my mother wanted busy children. It was very important that her house should remain at all times clean and tidy.
You could turn your back for a moment in my mother's house, leave a half-written letter on the dining room table, a magazine open on the chair, and turn around to find that my mother had "put it back where it belonged." as she explained.
My wife, on one of her first visits to my mother's house, placed a packet of biscuits on an end table and went to the kitchen to fetch a drink. When she returned, she found the packet had been removed. Confused, she set down her drink and went back to the kitchen for more biscuits, only to return to find that her drink had disappeared. Up to then she had guessed that everyone in my family held onto their drinks, so as not to make water rings on the end tables. Now she knows better.
These disappearances had a confusing effect on our family. We were all inclined to (有...的倾向) forgetfulness, and it was common for one of us, upon returning from the bathroom, to find the every sign of his work in progress had disappeared suddenly. "Do you remember what I was doing?" was a question frequently asked, but rarely answered.
Now my sister has developed a second-hand love of clean windows, and my brother does the cleaning in his house, perhaps to avoid having to be the one to lift his feet. I try not to think about it too much, but I have at this later time started to dust the furniture once a week.
56. Which of the following is TRUE about my mother?
A. She enjoyed removing other's drinks.
B. She became more and more forgetful.
C. She preferred to do everything by herself.
D. She wanted to keep her house in good order.
57. My wife could not find her biscuits and drink in my mother's house because _______.
A. she had already finished them B. my mother had taken them away
C. she forgot where she had left them D. someone in my family was holding them
58. The underlined part to the fifth paragraph suggests that my sister _______.
A. is happy to clean windows B. loves to clean used windows
C. is fond of clean used windows D. likes clean windows as my mother did
59. This passage mainly tells us that _______.
A. my mother often made us confused
B. my family members had a poor memory
C. my mother helped us to form a good habit
D. my wife was surprised when she visited my mother
I am sure that everybody in his/her life has used computers.Nowadays you can feel their presence everywhere—at home,at school,at work and they certainly make life easier.On the other hand,there are people who can work without them.
Anyway, I believe their presence is a good thing.Life with them seems less difficult and more comfortable.You can use them to choose your meal,to withdraw your money,and also to save your time,because these operations ale all controlled by computers.Therefore,you can hardly imagine the modern world without them;the whole planet seems to be one big computer society.
Nevertheless,problems call often appear in this area,too.To have a computer means you have to be quite rich and have the necessary skills to use it.However, think about questions like,“Are computers available for everyone, for rich and poor people,for people from villages and people from cities? Aren’t they too expensive? Is everyone able to learn how to use them and does everyone have the chance to access and work with them? How could everything in the future be dependent on them?”Therefore,I think our society will be divided into two pans.One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out of society and will actually be left far behind the other group.
Another question that bothers me is,computers are important and they’re good things in our life, but they aren’t everything. They are good as a help at school, quite often as entertainment, especially for young people, as an necessary tool to help in research etc. , but I think we shouldn’t be so dependent on them, because computers are only machines and machines can’t feel anything, can’t be human and sympathetic, and every action performed by computer can be interfered(干涉) with could cause these machines to crash or work badly.
In conclusion, I would like to say I am not against computers. I use computers too, but people should be wary all the time.
72.Which of the following best shows the structure of the passage?
①="Paragraph" ②="Paragraph2" ③="Paragraph" 3 ④Paragraph4 ⑤=Paragraph5
73.By saying“wary”(in the last paragraph),the author is trying to say,“People should”
A.be strongly for the use of computers because of its convenience
B.be careful with computers that will also cause problems
C.master more necessary computer skills
D.not do something that causes computers to work badly
74.In the third paragraph,the author presents his idea by.
A.asking questions for people to think about
B.giving examples to support his argument
C.raising questions and answering them
D.expressing his opinion directly
75.The author’s main purpose in writing the passage is to.
A.encourage us to use computers in our society
B.advise us to say no to computers from now on
C.remind us to care about the problems that computers bring
D.inform us that computers has become a necessary part of our life
