As I stood there I saw a young homeless man asking people for money so he could buy breakfast. It was early in the morning and most of the travelers simply ignored the young man or gave him a dirty look. But there was one exception(例外)——an older, well-dressed businessman. When the young homeless man moved to him, the gentleman looked straight into his eyes and quietly asked, “How much will you need?” I couldn’t hear what the young man said but watched as the older man pulled several bills from his wallet and calmly placed them in the young man’s hands.I did n’t know if the young man actually used this money for breakfast or for some other purposes. What I do know is that I saw two completely different reactions(反应) to the same situation. I saw people who were either afraid or distrustful. And then I saw this man who was not afraid and treated the homeless man as though he were a brother. I decided then and there that , even though(即使)we have to be careful in this world, I would rather be like him.41. How was the young man treated by most of the travelers?A. They were friendly, but they did n’t give him anything.B. Most of them looked at him in a cold way.C. They treated him politely and talked to him.D. Most of them smiled at him and give him a few coins.42. What did the businessman do when the young man move to him?A. He treated the young man like his brother and gave him some money.B. He didn’t talk to the young man, but he gave the young man some money.C. He walked away from the young man.D. He turned his back on the young man.43. What does the writer mainly want to tell us?A. We should be careful with others and only help those good people.B. We can choose to be kind to others when treating them.C. We need to be polite to those who help others.D. We should depend on ourselves when in trouble.44. What sentence will be the writer most probably end the passage with?A. In this world, not many people take pity on others.B. Love should be offered to young children instead of young men.C. We hope each day will bring us many chances to show kindness.D. Helping others is necessary, but try to be careful of bad people.45. What does the underlined word “bill” mean?A. a piece of paper moneyB. a list of programmesC. a list with names of dishesD. a list to show how much money one should payBNatural resources like coal and oil are useful, but the overuse of them has caused serious environmental problems. People are trying to find new clean energies. These energies do not pollute the air, the water or the ground. Solar power is one of them.Solar power is a new type of energy. It is taken from the sun by using solar panels. The solar panels are usually fixed on the roofs(屋顶) of houses and buildings. It is the family solar power system(系统). Some countries are even beginning to build solar power plants(电厂) by setting thousands of solar panels in the places where there is enough sunshine. Solar power is good for the environment. The power is easy to get and will never be used up. Whenever it is sunny, there is power. The power isclean and renewable. It helps to reduce waste and pollution. In the areas that are too far away to send electricity(电) to or not easy to build electric power planets, solar power is especially necessary. It helps the people there to use lights, TVs, computers, washing machines, fridges and many other things.Therefore ,more and more countries, such as China, the USA, Japan and India, have put solar power to use. However, the power is not as widely used as expected.One of the difficulties is that a solar power system needs sunshine. Countries or areas with a lot of rain, like the UK, are not the right places to develop such power systems. Secondly, a solar power plant needs a very large site to fix enough solar panels to collect sunlight and change it into electricity. Maybe an area in the desert(沙漠) would be one of perfect places for such a plant to build. What’s more, solar panels are expensive at present though the energy itself doesn’t cost anything.Today people are working hard to develop more practical and cheaper solar power systems. Maybe one day solar power will be one of the most important clean energies in our life.46. Which is NOT true about solar power?A. It is clean.B. It is easy to get.C. It is overused.D.

34.在做“探究在气压强存在”的实验时,小英将酒精棉点燃放入瓶中,将去皮的熟鸡蛋堵 住瓶口,如图 26 所示.发现瓶子把鸡蛋“吞”了进去.因此,小英认为是大气压把鸡 蛋压入了瓶中.小青不同意这个观点,她认为瓶中空气受热后,有部分空气跑到瓶外, 瓶中空气稀薄,对鸡蛋的托力变小,鸡蛋是在重力作用下进入瓶中的.请你用小英的实 验器材,做实验证明,小英的观点是正确的.

If you are falling,do you believe they will catch you and help you stand up?Our teacher helped us to get the answer.One day,Mr Morrie came into the classroom and said he had a game for us to try.He divided us into two groups.One student from the first group ,stood in front of us with his eyes closed,and then fell backwards.The second group stood behind him.Before he fell on the floor,they should catch him and not let him get hurt.Most of us were uncomfortable with this.We were afraid that they wouldn’t catch us and we would hit the floor.So we didn’t move.We just stood there and laughed in embarrassment.Finally,one student,a thin,quiet,dark-haired girl called Sarah,decided to move.She crossed her arms in front of her body,closed her eyes ,and slowly fell backwards .She looked quiet but brave.For a moment,I was sure that she was going to fall on the floor .But before she hit the floor,the other students caught her,help her and finally helped her stand up.“Whoa1”We were all surprised ,and also encouraged .The girl was happy,too.Seeing this, Morrie smiled and said to the girl,”when you close your eyes ,you can’t see anything.You won’t feel safe.When you are falling,the feeling gets stronger.You are not sure whether you will hit the cold,hard floor or the warm,soft hands of your friends.But if you are brave enough to trust them,they will not let you down.41.What is Morrie?A.A studentB.A teacherC.A managerD.A farmer42.Why didn’t the students move at first?A.They didn’t want to play the game.B.They thought the floor was dirty.C.They didn’t understand MorrieD.They were afraid of falling down.43.What did the writer think of the girl?A.CarefulB.ActiveC.Quiet but braveD.Careless44.What happened to the girl in the end?A.She fell on the groundB.She felt sadC.Only the writer helped herD.The other students caught her.45.Why did the students feel encouraged?A.They felt they could trust each otherB.They could stop the game finally.C.They wanted to do something elseD.They thought they won the game.BHabit is an action that we have performed so often that it becomes something that we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to get rid of these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.First, look at why you do it. In other words, what's the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it? It may make you feel a little better for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get more time to spend on the Internet!Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn. When you think that way, you'll find that it's not wise to keep your bad habit! Now it is time to make a decision. What will you choose? I'm sure you will choose to do what you think is more important.1. From the first paragraph we know that ______.A. a habit is a terrible thing that we can never changeB. people take countless hours and dollars to get rid of habitsC. none of the people who try to break bad habits are successfulD. though it is difficult, we can still do something about our bad habits2. The underlined sentence "there is no shortcut to achieve it" means that ______.A. it is not easy to get rid of bad habitsB. there is a long way and a short wayC. something dangerous may happenD. we must cut it in a short time3. According to the reading, if you want to get rid of your habits, you have to ______.A. talk to others when you are in low spiritsB. know why you do what you doC. finish your homework firstD. spend less time on the Internet4. Which of the following does NOT happen because of a bad habit according to the reading?A. You are punished later.B. Making people around you feel unhappy.C. You feel a little better after shouting at others.D. You leave your homework at home by accident.5.
