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 |
Greg Woodburn, a student at the University of Southern California, spends a lot of time cleaning sneakers he collected．But soon the shoes will be sent to poor children in the United States and 20 other countries, thanks to Woodburn’s Share Our Soles (S.O.S.) charity．
A high school track star in the town of Ventura, California, Woodburn was treated in hospital for months with knee and hip injuries．
“I started thinking about the health benefits, the friendship and the confidence I got from running,” he says, “And I realized there are children who don’t even have shoes．”
Woodburn gathered up his old sneakers, then asked his friends to donate．His goal was to have 100 pairs by Christmas this year．When he collected more than 500 pairs, he decided to turn the shoe drive into a year-round endeavor．
Back then, the sneakers came from donation boxes at the YMCA and the local sporting goods store and from door-to-door pickups．Woodburn has now set up collection boxes at two high schools, city gym and recreation center．He has started accepting adult sizes and sandals．So far, S.O.S has collected and donated more than 3,000 pairs．
Woodburn has cleaned all the shoes．After sorting the shoes by size, Woodburn selects the good shoes for the washing machine and the worn-out ones for recycling．
To ship the footwear, Woodburn teamed with Sports Gift, a nonprofit organization that provides soccer and baseball equipment to children around the world．Keven Baxter, founder and president, says, “We’d send kids balls and shoes．I've heard that for many of these kids, these old sneakers are the only shoes they had．They wear them to school and to do sports．So Greg’s running shoes were a nice addition for us．”
For many recipients, the shoes represent opportunity．Two young boys in Southern California attended school on alternate days because they shared a pair of shoes．They were too big for one boy and too small for the other．Thanks to S.O.S., each brother received his own pair of shoes．The boys now attend school daily and enjoy their learning．When they graduate, they say, they will help a stranger, just as Woodburn helped them．What caused Greg Woodburn to donate old shoes for poor children?
| A．The benefits from playing sports． |
| B．News about some poor children． |
| C．His reflection to school life． |

| D．expand his endeavor in the whole city |
How did Woodburn manage to deliver the shoes collected?
| A．By sending them by mail． |
| B．By working with Sports Gift． |
| C．By advertising for those in need． |
| D．By offering them from door to door． |
What can we learn from Keven Baxter’s remarks?
| A．Sports Gift is popular around the world． |
| B．Many children need Greg’s old sneakers． |
| C．Greg’s running shoes are the best gifts for children． |

Going to school from 8 am until 5 pm may sound terrible，but Sydney Shaw，a seventh grader at the Alain Locke Charter Academy on Chicago's West Side，has come to like it—as well as the extra 20 or so days that she's in class every year．“I'm sure every kid at this school says bad things about the schedule sometimes，”says Sydney, who was at school on Columbus Day, when most Chicago schools had a holiday．“But we all know it's for our benefit.”
Finding ways to give kids more classroom time，through longer hours，a longer school year，or both，is getting more attention．“If you want to look at schools where the achievement gap is narrowing, they're saying they couldn't do it without the added time，”says Jennifer Davis．“Even when you get good teachers into schools，you also need more time．”
According to studies, low-income students fall back more than two months in their reading skills over summer vacations．“It's over the summer months that poor kids fall behind，”says Karl Alexander，a sociologist．“If you have parents who themselves didn't succeed at school and aren't highly educated，kids aren't going to get those skills at home．”
Schools are asked to take a full year to plan how to best use the extra time—a process involving teachers，principals，students and parents．They are given outside support to help them base their plans on the best available analyses of student needs．It's still early，but officials are already seeing stronger test scores and a narrowing achievement gap．
But some critics are worried．“We risk producing something that's very expensive and time-consuming, and that will give educators a lot of trouble，”says Frederick Hess．“Before we spend all that extra money，I'd much rather see if we can figure out how to get 50 percent more instructional time out of the current school day．”From the first paragraph，we learn that．
| A．the longer schedule is harmful to kid's health |
| B．all Chicago students had a holiday on Columbus Day |
| C．Sydney Shaw supports the added time |
| D．few kids are bored with the lack of holidays |

| A．no good teachers are willing to teach them |
| B．they can't get help from their parents |
| C．their parents are unwilling to hire private teachers |
| D．they themselves have no desire to learn |
Some people are worried about adding school hours mainly because．
| A．it will have a bad effect on the kids’ futures |
| B．the current school day has been too busy |
| C．no one supports the idea |
| D．it will be costly and time-consuming |
The text is mainly about．
| A．whether a longer school day will help narrow the achievement gap |
| B．how students have benefited from additional school hours |
| C．why the achievement gap among students needs to be narrowed |
| D．what causes the achievement gap among students |
When I was going home to India last year, I called up my mother to ask if she wanted anything from China.
When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and jeans. Thankfully, we can get all these anywhere in India now.
Still, her answer surprised me: “Green tea.”
As long as I can remember she didn’t even drink Indian tea.
I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses.
At the turn of the century, China was not really familiar to the average Indian. It was a strange country.
How things change! And how soon!
Now every town of any size seems to have a “China Market”. And everyone is talking about China.
The government of India has planned to send a team to China to see how things are done. A minister once said that India must open the doors for more foreign investment (投资) and such a step would “work wonders as it did for China”.
But it’s a two-way street. I just heard about a thousand Shenzhen office workers who have gone to Rangalore to train in software. Meanwhile, all the IT majors are setting up a strong presence in China.
No wonder that trade, which was only in the millions just ten years ago, is expected to hit about US $15 billion for last year and US $20 billion by 2012, a goal set by both governments.
No wonder, my colleague wrote some weeks ago about this being the Sino-Indian (中国和印度的) century as the two countries started on January 1st the Sino-Indian Friendship Year.
But what is still a wonder to me is my mother’s drinking Chinese tea.Why did the mother ask for Chinese green tea?
| A．She was tired of Indian tea. |
| B．She had a son working in China. |
| C．She believed it had a curing effect. |
| D．She was fond of Chinese products. |
What does the author mean by “it’s a two-way street” in Paragraph 10?
| A．China and India have different traffic rules. |
| B．Tea trade works wonders in both India and China. |
| C．Chinese products are popular in both China and India. |
| D．There are exchanges between India and China. |
What do we know about the Indian IT industry?
| A．It is seeking further development in China. |
| B．It will move its head office to Shenzhen. |
| C．It has attracted an investment of US $15 billion. |
| D．It caught up with the US IT industry in 2008. |
In the text the author expresses _______.
| A．his concern for his mother’s health |
| B．his support for drinking Chinese green tea |
| C．his surprise at China’s recent development |
| D．his wonder at the growth of India’s IT industry |
It is inferred in the text that _______.

| B．the Indians were not familiar with China before |
| C．the government of India encourages their people to buy Chinese green tea |
| D．the two countries didn’t cooperate until last year |
Nothing succeeds like confidence. When you are truly confident, it radiates (辐射) from you like sunlight, and attracts success to you like a magnet (磁铁). Besides, those who are self-confident can in turn inspire (encourage) confidence in others: their audience, their peers, their bosses, their customers, and their friends. And gaining the confidence of others is one of the key ways in which a self-confident person finds success.
So how can we build a sense of self-confidence and prepare ourselves on the way to success?
First, do what you believe to be right, even if others mock or criticize you for it. Believe in yourself and believe that you can do it in any situations, because if you believe you can, then you really will. The belief keeps you searching for answers, which means that pretty soon you will get them.
Second, govern your behavior based on what other people think. What’s more important, be willing to take risks and go the extra miles to achieve better results, in which case mistakes can not be avoided. Always be ready to admit your mistakes, and learn from them. Next, work hard to settle the problems in order to cover up your mistakes before anyone notices. Building self-confidence is readily achievable, as long as you have the focus and determination to carry things through. And what’s even better is that the things you’ll do to build self-confidence will also build success -- after all, your confidence will come from real, solid achievement. No one can take this away from you!
As you sow, so will you reap. With your perseverance (毅力) and improvement, you are getting closer to success. At this stage, wait for others to give congratulations and compliments on your achievements. “Thanks, I really worked hard on it. I’m pleased you recognize my efforts.” The congratulations and compliments from others will promote you to gain further success.
Self-confidence is extremely important in almost every aspect of our lives, and it is no wonder that so many people struggle to find it. Self-confidence really can be learned and built on. Besides, whether you’re working on your own self-confidence or building the confidence of people around you, it’s well worth the effort! Those who are truly confident _______.
| A．succeed without effort and hard work |
| B．encourage people around to become confident |
| C．appear more attractive and thus become successful |
| D．gain the confidence of others and feel successful |

| A．praise | B．imitate (模仿) | C．punish | D．laugh at |
When others congratulate us on our achievements, we are supposed to _______.
| A．praise them in return |
| B．gain further improvement |
| C．politely accept the compliments |
| D．expect them to congratulate you again |

| A．Look before your leap. |
| B．It is no use crying over spilt milk. |
| C．Genius is 1% inspiration and 99% perspiration. |

| C．encourage people to build confidence and achieve success |
| D．criticize people who lack confidence and thus fail in their career |
“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft (the crime of stealing): a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts (warning) on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely (远程地) switch to an alternative (可替换的) password immediately if they fear that the thief has also got hold of the access (进入, 使用) details.
If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.The underlined expression “to give the thief a piece of their mind” in Paragraph 2 can be understood as “_______”.
| A．to give the thief an alert mind |
| B．to express the owners’ anger to the thief |
| C．to remind the thief of his conscience (良心) |
| D．to make the thief give up his mind |
Different from other security software, Retriever can _______.
| A．record the stealing process |
| B．help recognize the lost laptop |
| C．lock down the computer remotely |
| D．send a spoken message |
One function of the program is that it allows the owner to _______ at a distance.
| A．change some access details for switching on the laptop |
| B．turn on the laptop by using the original password |
| C．operate the laptop by means of an alternative password |
| D．erase the information kept in the stolen laptop |
Which of the following can best sum up the main idea of the passage?
| A．With no Retriever, thousands of laptops are stolen every year. |
| B．A new software provides a means to reduce laptop theft. |
| C．Retriever has helped to find thieves and lost computers. |
| D．A new program offers a communication platform with the thief. |
What does the word “it” in Paragraph 4 refer to?
| A．the alert message | B．the computer |
| C．the program | D．the laptop |
