We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of energy for our planet. It causes the evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.According to the passage, the root( 根本的) cause for weather changes on the Earth is .
| A．the atmosphere surrounding the Earth |
| B．water from oceans and lakes |
| C．energy from the Sun |
| D．greenhouse gases in the sky |
Only a small part of the Sun’s energy reaches the Earth’s surface because most of it is .
| A．absorbed by the clouds in the lower atmosphere |
| B．reflected by the gases in the upper atmosphere |
| C．lost in the upper and lower atmosphere |
| D．used to evaporate water from the oceans and lakes |
We learn from the passage that .
| A．all living things on the Earth depend on the Sun for their food |
| B．a forest looks dark in winter because it absorbs solar energy |
| C．only 0.023% of the energy from the Sun is made use of on the Earth |
| D．greenhouse gases allow heat energy to escape from the Earth’s surface |
When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally（道德方面）right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars. Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil（恶行）.
Secondly, there is the worry that the money you give will be spent on beer, wine or drugs.
Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
There is an opinion that the problem should be dealt with by the government rather than ordinary people. Some people think the local government department should help the beggars
It is hard to come to any final conclusion: there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver. What is mainly discussed in the passage?
| A．Moral deeds of people. |
| B．Arguments on giving to beggars. |
| C．Moral goodness of the giver. |
| D．Religious activities of the church. |
What can we infer from the underlined sentence “But has the world changed?” in Para.2 ?
| A．People no longer know who suffers misfortune in the village. |
| B．Some people will not do what was morally right in the past. |
| C．We don’t meet with those who need help any more. |
| D．Now it is the government’s duty to help the beggars. |
Which of the following is NOT mentioned in the passage?
| A．Some people dress up to pretend to be beggars. |
| B．Some beggars have no excuse for begging. |
| C．Some beggars use the money to buy drugs. |
| D．Some beggars need money for their children’s schooling. |
In the last paragraph, the writer thinks that it is hard to come to any final conclusion, because________.
| A．there is so much money wasted |
| B．there are so many beggars |
| C．the cases can be so different |
| D．there are so many different arguments |
Recently Dr. Cleiman has proved that everyone has a daily energy cycle. During the hours when you labor (work) through your work, you may say that you are “hot”. That is true, the time of day when you feel most energetic is when your cycle of body temperature is at its peak (顶峰). For some people the peak comes during the forenoon (上午前). For others it comes in the afternoon or evening. No one has discovered why this is so.
Much family quarrelling ends when husbands and wives realize what this energy cycle means and which cycle each member of the family has.
You cannot change your cycle, but you can learn to make your life fit it better. “Habits can help,” Dr. Cleiman believes. If your energy cycle is low in the morning but you have an important job early in the day, rise before your usual hour, and then you will work better at your low point.
Get off to a slow start which saves your energy. Get up with a lazy yawn(哈欠) and stretch(伸展). Sit on the edge of bed before putting your feet on the floor. Avoid the troublesome searching for clean clothes by laying them out the night before.Dr. Cleiman did not explain in the passage ___________.
| A．how people can make their life fit their cycle |
| B．whether everyone has a daily cycle or not |
| C．why people have their energy cycle at different times |
| D．what will happen in the family if the couple fail to realize which cycle each member has |
For what reason may husbands and wives quarrel with each other?
| A．Either of them gets up late in the morning. |
| B．Husbands and wives have different cycles of energy. |
| C．Either of them wants to change the cycle of the other’s. |
| D．They do not know which cycle they themselves have. |
According to the passage, ____________.
| A．one works better at one’s peak energy point |
| B．if you know your cycle you can change it to fit your life. |
| C．whenever you feel hot, your energy cycle reaches the highest |
| D．your energy cycle must be in the morning if you can get up early |
Which of the following can save your energy in the morning?
| A．Getting up late. |
| B．Jumping out of bed as quickly as possible. |
| C．Looking for clean clothes. |
| D．Sitting for a while before getting out of bed. |
Today, traditional opinions about men still exist. A man has to be strong, brave, sports loving and manly. Anything less would not be considered manly. Sports such as football, basketball and boxing all tend (往往是) to be men’s sports. However, the dance of ballet is considered feminine because it requires nice movements. This tradition is shown in the movie, Billy Elliot.
Billy Elliot is a movie that protests against this traditional view of men. Billy Elliot is an eleven-year-old boy that has a natural talent for ballet dancing, but his father will not allow it. Billy’s father wants him to take up boxing and become stronger, but Billy goes against his father’s wishes and takes up ballet dancing. This difference of opinion makes Billy sad. What’s more, his friends also laugh at him.
After saving enough money, his father sends Billy to a weekly boxing course; however, Billy doesn’t enjoy boxing because he always loses in matches and is often hurt. His ballet teacher, Mrs. Wilkinson thinks that men or women should not be judged by the activities they like to do, so she tells Billy’s father that although he wants his son to make a good living, he should let his son do what he loves to do because he has a talent for it. When his father finally realizes the truth, Billy is surprised. In the end, with the help of his father, brother and all the people around him, Billy goes to the Royal Ballet Academy in London and becomes a very successful ballet dancer.The underlined word “feminine” in the first paragraph most probably means ______
| A．of men | B．of children | C．of women | D．of students |
Why is Billy laughed at by other children?
| A．He always loses in boxing matches. | B．He isn’t strong. |

From Billy’s story, we can see that _______.
| A．children should accept their parents’ opinions |
| B．we should try to fight against traditional opinions |
| C．men and women play different sports |
| D．parents should let their children do what they are interested in |
One day, a poor boy who was trying to pay his way through school by sending newspapers door to door, was so hungry that he decided to beg for a meal at the next house.
However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe (欠) you?”

I was the youngest of five boys and also had four sisters who had to pull together and take care of each other. Dad wasn't around, so I never knew him well. He killed himself when I was three years old, leaving mom with the job of raising nine kids. She was a very hard worker, and in order to make ends meet, she hardly ever rested. With my mom as my example, I learned that hard work is the best way to get what you want.
Even as a little boy, I knew I was going to be successful. Regardless of what I chose, I wanted to make my brothers, sisters and mom proud of me—not only by being successful in what I chose to do, but also as a person who could be looked up to for the right reasons.
Surprising as it might seem, basketball wasn't in my plans. One day, my mom cut a rim(边缘) off an old water barrel(水桶) and then held it up for me to throw an old rubber ball through. By junior high, I started playing basketball on a team. I loved to compete. For me, it paid off. I always put the effort in, every day.
I am grateful for the life I've enjoyed as a basketball star. Basketball is not life. It can be exciting. But the most important thing about basketball is that it gives me a way to do good things for others as I move through this journey called life.It can be inferred that the author's________.
