（一）一切皆有可能
（1）水能流向天空吗？答曰：绝对不可能！可是，填上的彩云却正是地面流向天空的水，当水变成气体，它就能袅袅地“流”向天空。人生不也这样吗？不要以为自己没有升腾之日，一切皆有可能。
（2）一个小学即辍学、靠帮人推磨换书看的放牛娃，能成为诺贝尔文学奖的得主吗？在一般人看来，这是绝对不可能的事情，但是，诺贝尔文学奖得主莫言正是50年前的那个放牛娃。
（3）一个高考数理化三科总成绩不足100分，复读都没有学校肯要的落榜生，他会成为著名的记者和节目主持人吗？一般人看来也不打可能，但是，如今大红大紫的孟 非正是当年的那个落榜生。
（4）辩证法告诉我们，任何事物都不是孤立地存在，总是同诸多其他事物发生着联系，因而其发展就具有多种可能性。丘吉尔说：“一个人活得愈长，他就愈能认识到一切取决于机会，任何人哪怕只回顾一下十年前的经历，他就会看到，某些看似毫不重要的细节实际上都左右了他的全部命运和前程。”世界充满偶然性，也充满奇迹， 奇迹正是偶然性的表现。

（6）既然一切都有可能，那我们就等天上掉馅饼吧！
（7）不！一切都有可能，一切也都可能是泡影。偶然进入蚌中的沙，若拒绝磨砺，不会成为温润赛玉的珍珠；偶然遗于石缝的种子，若无韧如磐石之志，不会长成黄山上气势如虹的迎客松；偶然被蒸发的水，若惧怕颠簸，也不会成为自由飘荡的云。没有“踏破铁鞋”的痛苦，哪能体验到“ 全不费功夫”的快乐？没有“众里寻他千百度”的艰辛，又岂能有“蓦然回首”的惊喜？
（8）也许现在的你是一株小草，但一切皆有可能的自信会助你长成参天大树；也许现在的`你是一朵无名的花儿，但一切皆有可能的付出会助你将来艳压群芳。朋友，一切皆有可能，我辈当努力。
10、文章开头从水能流向天 空的现象说起，有哪些作用？请写出两点。（4分）

（二）司马光好学《三朝名臣言行录》
司马温公幼时，患记问不若人，群居讲习，众兄弟既成诵，游息矣；独下帷绝编，迨能倍诵乃止。用力多者收功远，其所精诵，乃终身不忘也。温公尝言：“书不可不成诵，或在马上，或中夜不寝时 ，咏其文，思其义所得多矣。”
13、解释 下列句中加点的词。（16分）

10、（4分，写出两点即可）激发读者阅读的兴趣；引出文章的中心论点；充当论据。
11、（4分）莫言从放牛娃成为诺贝尔文学奖得主；一切皆有可能。
12、（4分）一切都有可能，一切也都可能是泡影（一切也都可能是泡影）
【译文】司马光幼年时，担心自己记诵诗书以备应答的能力不如别人。大家在一起学习讨论，别的兄弟已经会背诵了，去玩耍休息了；（司马光却）独自苦读，像董仲舒和孔子读书时那样专心和刻苦，一直到能够熟练地背诵为止，（由于）读书时下的力气多，收获就长远，他所精读和背诵过的书，就能终身不忘。司马光曾经说：“读书不能不背诵，在骑马走路的时候，在半夜睡不着觉的时候，吟咏读过的文章，想想它的意思，收获就多了！”

An egg sinks to the bottom if you drop it into a glass of drinking water, but what will happen if you add salt? The results are very interesting and we can learn something from the fact.
First pour water into the glass until it is about half full. Then put lots of salt into the water(about 6 spoons).
Carefully pour in drinking water until the glass is nearly full. Be careful not to mix the salty water with the drinking water.
At last, put the egg into the water and watch what happens.
Salt water is heavier than drinking water. When you put the egg into the water it drops through the drinking water until it reaches the salty water.
There the water is heavy enough for the egg to stop. So the egg will stay there. If you do the experiment carefully, you’ll see the egg stay in the middle of the glass. Fun? Have a try!

Learn to relax yourself
Now many students are under too much pressure. They always feel too tired to listen to teachers carefully in class.
It’s important for students to relax. Only in this way can they study well and be healthy. Here are some different ways to relax yourself. For example, you can try sleeping enough, or you can listen to your favorite music. You can also read some books or do some sports. For me, I often hang out with my friends.
While you are studying, don’t forget to relax. You may study better after a good rest.

三、完形填空(共10小题;每小题1分，满分10分)
Some people believe that some star signs get along better with each other than other star signs.
Perhaps we should first start with those signs that are incompatible (合不来的).Aries and Leo are not a good mix. 1 of them are leaders. Aries is energetic and is not compatible with Leo because Leo is strong and confident. Also, Pisces and Taurus are not a good pair. Taurus is practical and will not be 2 to wait for Pisces to stop 3 !
Perhaps the best choice of friend for Taurus is Capricorn. Taurus can be stubborn and Capricorn is patient and would be prepared to wait for Taurus to change his or her 4 . Aries should get to know Pisces. Aries is active but Pisces is gentle and easy-going. They are a good match. Leo would be matched 5 with Libra. Leo likes to give gifts and Libra likes beautiful things.
The perfect pair are Libra and Scorpio. Libra does not like to 6 and loves peace. Libra will never ask Scorpio about his or her secrets. In addition, Libra will be quite happy to watch Scorpio 7 things. Sagittarius and Gemini are also a perfect match. Sagittarius loves to travel and Gemini loves to 8 new things. Sagittarius has a good sense of humour and will enjoy 9 Gemini talk.
Virgo and Aquarius are a good match too. Sometimes, however, there can be problems in their relationship. Aquarius has many friends but Virgo worries 10 about meeting a lot of people.
( ) 1. A. All B. Both C. One D. Each
( ) 2. A. enough impatient B. impatient enough
C. patient enough D. enough patient
( ) 3. A. dream B. dreams C. to dream D. dreaming
( ) 4. A. mind B. secret C. name D. details
( ) 5. A. bad B. badly C. well D. good
( ) 6. A. save time B. argue C. dream D. wait
( ) 7. A. to do B. does C. did D. doing
( ) 8. A. look at B. look C. discover D. look after
( ) 9. A. listen B. listen to C. listening to D. listening
( ) 10. A. a lot of B. lots of C. many D. a lot
四、阅读理解(共13小题;每小题2分，满分26分)

When you are feeling unhappy or forget how great you are, these are six ways to make you feel good about yourself.

3) Smile! Be friendly to people you meet. Look for the good things in your friends and family.
4) Learn something new! Have you always wanted to decorate ( 装修 ) your own room or learn how to swim? Go for it! New challenges ( 挑战 ) are fun and give you a sense of accomplishment when you have finished.
5) Read and start a diary. Turn off the TV and let your imagination fly! Write down your thoughts, dreams or anything you want! Writing always helps to express your feelings.
6) Stay with your family. We all need our family time. Talk with your Mum or Dad or maybe even your cousin.

Americans have used colors to create many expressions they use every day.
We say you’re ‘in the pink’ when we are in good health. It is easy to understand how this expression was born. When my face has a nice fresh, pink color, it is a sign my health is good.
The color green is natural for trees, it is an unnatural color for humans. When someone doesn’t feel well, someone who is sick, for example, we say he ‘looks green’. When someone is angry because he doesn’t have what someone else has, we say he is ‘green with envy’.
Some people are ‘green with envy’ because someone else has more dollars, or ‘green backs’. Dollars are called ‘greenbacks’ because that’s the color of the backside of the money.
Blue is a cool color. The traditional blue music of American blacks is the opposite of red hot music. It is slow, sad and soulful ( 深情的 ). To be blue, of course, is to be sad.
The color black is often used in expressions. People describe a day in which everything grows wrong as a ‘black day’. A ‘black sheep’ is the member of a family or group who always seems to be in trouble. If someone meets a ‘black cat’, something unlucky might happen to him. Not all the ‘black’ expressions have bad meaning. A company ‘in the red’ is losing money. If someone tells you to put someone ‘in black and white’, they want you to write it down.
( ) 7. After reading the passage, we can infer ( 推断 ) if someone ‘looks grey’, he _______.
A. looks well B. may need a doctor
C. is healthy D. is ‘in the pink’
( ) 8. I was really _________ when I saw his nice new car.
A. red B. blue C. green D. black
( )9. Which of the following is true?
A. A company surely likes to be ‘in the red’.
B. All the color expressions in the passage come from Britain English.
C. Not all the ‘black’ expressions have bad meanings.
D. Dollars are called ‘greenbacks’ because they have trees on the backside.

Expressions cover all parts of our life. They may be around your ears every day. You may know a lot of Chinese expressions that describe how you feel. Here are some English ones for your enjoyment.
Have Your Heart in Your Mouth
This expression means that you’re really afraid or anxious about something. When your heart starts beating so much that you can feel a thumping(怦怦跳 ) in your throat, it may feel like you “have your heart in your mouth”.
Have Butterflies in the Stomach
How did butterflies get in your stomach? Well, those really aren’t butterflies in there. It is a way of describing those nervous feelings you might get before a test or a very important decision.
These stomach flutters( 跳动 ) are normal and happen to many people. Some people believe having a few butterflies might even help you perform better.
Sick as a Dog
If you’ve ever been very sick, you may have used this expression. Because dogs eat just about anything they find, they often get sick. So it’s all right to describe someone who’s not feeling well as being “sick as a dog” .
Under the Weather
When it’s rainy all day outside ,how would you feel? This expression comes from the idea that bad weather might hurt a person’s health and mood .

The word ‘day’ has two meanings. When we talk about the number of days in a year, we are using ‘day’ to mean 24 hours. But when we talk about day and night,we are using ‘day’ to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth.
At the equator day and night are sometimes the same length. They are each twelve h ours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening .For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere gets more hours of sunlight than the Southern Hemisphere(半球). Days are longer than nights.
South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.
( ) 7.When the western Hemisphere is having day, the Eastern Hemisphere is having ___________ .
A. both day and night
B. day
C. neither day and night
D. night
( )8. A place is moved from day into night and from night into day over and over by ___________ of the earth.

The colour systems(系统) used by scientists and artists are completely different. An artist will mix blue and yellow paint to get a shade of green; a scientist will mix green and red light to create yellow. The printed page in a magazine is yet another system.
Scientists recognize the light primaries(原色) are red, green and blue. When mixed, red and green light rays produce yellow, blue and green produce cyan, red and blue produce magenta. Red, green and blue mix to create white (light). This colour model is used in computer monitors, television sets and theatre.
Most artists recognize red, yellow and blue as the three basic primary colours. These primaries are the pure colours which cannot be created by mixing any other colours.
In the print industry, cyan, magenta, yellow and black are used as the primary colours. When you mix all the colours, the result is gray.
( ) 10.________ on the colour systems.
A. Scientists and artists have the same idea.
B. Scientists agree with artists
