Plants and animals usually do not live apart, as in many ways they are important to each other. Most green plants can make their own food. The food of other living things, even the food of meat-eating animals, comes directly or indirectly from green plants. For example, some people eat mutton (羊肉); mutton comes from a goat; the goats eat grass. These steps, or links, make up what is called a food chain. Without green plants, all other living things would in time die of starvation.
Plants help animals in other ways too. They furnish homes and shelter for many animals. Many birds, as you know, build their nests in trees. Deer and many other animals use bushes for shel­ter. And even man depends much upon plants for his shelter. Animals repay some of this debt by helping plants. You may be aware that many insects and some birds do important work for plants by pollinating (授粉) them. You must have also learned how animals often help plants by spreading seeds.
What is waste material for one of these kinds of life is often valuable substance for the other. For example, animals give off carbon dioxide gas when they breathe. When plants make food, they absorb this gas from the air, using the carbon and releasing some of the oxygen back into the air. The oxygen that is released, then, is again supplied to animals. Thus the cycle continues, ani­mals helping plants, and plants helping animals.
All plants and animals have their enemies. Insects eat plants; birds eat insects; other animals kill birds. But here too, animals such as birds and bats help the plants by destroying harmful in­sects. Many plants and animals are helpful to some living things but are harmful to others. Then there are other rules in nature that act as checks and balances. For example, if there are more animals in a certain area than there is food to support them, some of the animals must mi­grate or starve. In either case, the number of animals will be reduced until the balance between animals and the available food supply is restored.
These helps and hindrances (障礙) are constantly going on in the plant and animal world to achieve a balance. As long as one living thing is dependent on another, whenever the scales are tipped (使傾斜), nature takes steps to balance the scales again.

I have a friend named John Roberts who owns a horse ranch （牧馬場(chǎng)）in San Ysidro.　　The last time I was there he shared a story with me. “It is a story about a young man who was the son of an itinerant horse trainer. When he was a senior，he was asked to write a paper about what he wanted to be and do when he grew up.”
That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch， showing the location of all the buildings，the stables and the track.　　
“The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, ‘See me after class.’”
　　“The boy went to see the teacher after class and asked, ‘Why did I receive an F？’”
　　“The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from an itinerant family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you’ll have to pay large stud fees. There‘s no way you could ever do it.’ Then the teacher added， ‘If you will rewrite this paper with a more realistic goal, I will reconsider your grade.’”
　　“The boy went home and asked his father what he should do. His father said, ‘Look, son， you have to make up your own mind on this. However, I think it is a very important decision for you.’”
　　“Finally，after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, ‘You can keep the F and I’ll keep my dream.‘”
　　John continued, “I tell you this story because you are sitting in the middle of my 200-acre horse ranch. I still have that school paper framed over the fireplace.” He added, “If I had changed my paper at that time, maybe we would not have the chance to be here talking about the dreams .”
小題1:What was the boy’s goal described in his seven-page paper? (No more than 6 words)
小題2:Why did the teacher give him a F”?                    (No more than 14 words)
小題3:How did John’s father respond to his son’s puzzlement?    (No more than10 words)
小題4:What can we learn from the article?                    (No more than 8 words.)

閱讀下面短文并回答問題，然后將答案寫到題后的橫線上（請(qǐng)注意題后的詞數(shù)要求）。
[1]Some people's ears produce wax like busy little bees. This can be a problem even though earwax appears to serve an important purpose. Experts say it protects and cleans the ear. It traps dirt and other matter and keeps insects out. Doctors think it might also help protect against infections. And the waxy oil keeps ears from getting too dry.
[2]So earwax is good. It even has a medical name: cerumen. And there are two kinds. Most people of European or African ancestry have the "wet" kind: thick and sticky. East Asians commonly have ___________.But you can have too much of a good thing.
[3]The glands(腺體) in the ear canal that produce the wax make too much in some people. Earwax normally falls out of the ear or gets washed away. But extra wax can harden and form a blockage that interferes with sound waves and reduces hearing. People can also cause a blockage when they try to clean out their ears，but only push the wax deeper inside. Earwax removal is sometimes necessary. But you have to use a safe method or you could do a lot of damage.
[4]Experts at N.I.H., the National Institutes of Health, suggest some ways to treat excessive earwax yourself. One way to remove wax is known as irrigation. With the head upright, take hold of the outer part of the ear. Gently pull upward to straighten the ear canal. Use an injector device to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.
[5]The experts at N.I.H. say you may have to repeat this process a few times. Use water that is body temperature. If the water is cooler or warmer, it could make you feel dizzy. Never try irrigation if the eardrum is broken. It could lead to infection and other problems.
[6]After the earwax is gone, gently dry the ear. But if irrigation fails, the best thing to do is to go to a health care provider for professional assistance.
小題1:What’s the purpose of the passage? (No more than 10 words)
___________________________________________________________________.

閱讀下面的短文和問題，根據(jù)短文內(nèi)容，完成對(duì)該問題的回答。答語要書寫工整，字跡清楚，結(jié)構(gòu)正確，不多于八個(gè)單詞。
It is essential to our children’s development that they are provided with life skills. It is of great importance that our children should be taught basic life skill lessons in order to live the life they dream of as they enter adulthood.
How we teach youth life skills is the focus of this article. We will explore and share life skill lessons with you so that the time you spend with each child is more productive and moves them to take positive action.
What should be included in a youth life skills program?
1）Financial literacy（理財(cái)素養(yǎng)）. Financial literacy training can improve every aspect of a child’s life. Studies show that people that have developed financial literacy skills are healthier, have better relationships, and have more confidence. Financial literacy training is the foundation which all the other youth life skills can build on and support.
2）Relationships. Children need to understand the importance of encouraging relationships and develop the skills to maintain positive relationships. One key part of developing positive relationships is the ability to communicate effectively. This is a life skill that will not only benefit （使受益）their friendships but will help them in their careers as well.
3）Strengths development. It is important for adults to focus on the strengths of their children and help them to take their strengths to the next level. For most, what we are good at is also what we enjoy doing. Make your youth life skill program one that helps them follow their passions and build upon the strengths they have developed while growing up.
The focus of youth skills programs is recognizing students’ potential and providing them with the proper tools to enable them to develop their skill sets. You are helping to open up windows of opportunity for them and encouraging them throughout the process by making them feel worthy.
The goal of youth life skill programs is to help our children grow into responsible adults. Children cannot grow into the wonderful human beings they are meant to be when they are shut down, turned away and ignored. They need the proper guidance that will enable them to feel proud of their achievements. They also need the opportunity to express themselves in an environment that is willing to listen to them and to help them as well. There is only so much they can stand on their own; the rest is up to the adults that play important roles in their lives.
小題1:What is important for children to learn according to the article?
______________________________________________________________
小題2:Who do you think the article is written to, students or teachers?
______________________________________________________________
小題3:What can children benefit from financial literacy skills?
______________________________________________________________
小題4:How can we encourage children to keep learning the life skill course?
______________________________________________________________
小題5:What do children need so that they can learn to stand on their own?
______________________________________________________________

Abraham Lincoln was born in Kentucky on February 12, 1809. When he was a small boy, his family moved to Indiana. Here, his mother taught him to read and write. Lincoln had very little formal education, but he became one of the best-educated men of the Great West.
When Lincoln was a young man, his family moved to the new state of Illinois. Lincoln had to make a living at an early age, but in his spare time he studied law. He soon became one of the best-known lawyers in the state capital at Springfield, Illinois. It was here that Lincoln became famous for his debates with Stephen A. Douglas on the problem of slavery (奴隸制度).
In 1860, Lincoln was elected President of the United States. He was the candidate of the new Republican Party. This party is against the creation of new slave states. Soon after his election, some of the Southern states quit from the Union and set up the Confederate States of America(美利堅(jiān)聯(lián)盟國(guó)). This action resulted in the terrible Civil War which lasted from 1861 to 1865.
On January 1,1863, during the war, Lincoln published his famous Emancipation Proclamation(解放宣言). In this file, Lincoln announced that all the slaves were to be free from that day. In 1865, after the war ended, another file was added to end the slavery everywhere in the United States. Early in 1865, the Civil War came to an end with the defeat of the South by the North. 
Only a few days after the end of the War, Lincoln was shot by an actor named John Wilkes Booth. The President died on April 14, 1865. In his death, the world lost one of the greatest men of all time.
小題1:Who taught Lincoln to read and write in his childhood?  (no more than 10 words) (2 marks)
小題2:When did Lincoln become the president of the U.S.?  (no more than 3 words)  (2 marks)

閱讀表達(dá)。閱讀下面的材料回答后面的五個(gè)小題。（每小題3分，滿分15分）
Joe Templer should have known better. After all, he works for a large auto insurance company. It won't hurt to leave the key in the truck this once, he thought, as he filled his gas tank at a self service gas station. But moments later, as he was paying the money, he saw the truck being driven away.
In 1987, 1.6 million motor vehicles were stolen in the United States one every 20 seconds. If _________________, experts predict annual vehicle thefts could exceed two million by the end of the decade.
Vehicle theft is a common phenomenon, which has a direct impact on over four million victims a year. The cost is astonishing.      
Many police officials blame professional thieves for the high volume of the thefts. It is a major money maker for organized crime. Typically, stolen cars are taken to pieces and the parts sold to individuals. But as many as 200,000 cars are smuggled out of the country every year. Most go to Latin America, the Middle East and Europe.
Only about 15 percent car thefts result in an arrest, because few police departments routinely conduct in depth auto investigations. When thieves are arrested, judges will often sentence them to probation（緩刑）, not immediately put them in prison because the prisons are overcrowded with violent criminals.
One exception is a Michigan program that assigns 92 police officers to work full time on the state's 65,000 car theft cases a year. Since 1986, when the effort began, the state's auto theft rate has fallen from second in the nation to ninth.

閱讀下面短文,根據(jù)第81至第84小題的具體要求,簡(jiǎn)要回答問題,并將答案轉(zhuǎn)寫到答題卡上。
Too many people want others to be friends，but they don’t give friendship back. That is why some friendships don’t last long. To have a friend，you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules：be honest；be generous；be understanding.
Honesty is where a good friend starts. Friends must be able to trust one another. If you do not tell the truth，people usually find out. If a friend finds out that you haven’t been honest，you may lose your friend’s trust. Good friends always count on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes of course. Instead you have to learn how to share things you enjoy，like your hobbies and your interests. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them，you help your friend know better.
Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be the first step in solving the problem. So a friend must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
No two friendships are ever exactly alike. But true friendships have three things in common. If you plan to keep your friends，you must practice honesty，generosity，and understanding.
小題1:Why don’t some friendships last long?  (not more than 15 words)    (3’)
__________________________________________________________________________
小題2:What does Generosity mean?   (not more than 1 words)     (2’)
