C

       The financial climate, the job market, family tensions, Obama moving into the Lincoln bedroom. Even the climate's getting in on the list. Yup, change is everywhere in 2009. If you're not careful, all kinds of strange things might happen in your otherwise ordered life, so it's best to work at avoiding change whenever it rears its head(出现).

       Here are 5 ways to do just that:

1.Ignore any opportunities

       How many times have you taken a chance, only for things to go wrong? How many times have you seized an opportunity only/'or it to slip between your fingers?

       There's always another mess waiting for you, so it's better to stay right where you are. Where you are right now is a known quantity-it's safe, warm and comfortable. Doesn't that sound better than going out there, messing up and looking stupid?

2.Set your expectations low

       If you're one of the people out there looking to make a change in 2009 rather than having change made for you, you'd better set your expectations low.

3.Keep on running and don't look back

       The best thing to do is to set things out so that you can do everything. It's good to be busy and running around after everyone else will mean that everyone's happy and there's no room for change to happen. It's a win-win!

4.Recognize that most changes are too big

       Face it; there are some tasks you're just not up to. Landing that exciting new job, getting a promotion, taking on the 'big project' or building a relationship that really works-these are all big challenges and you don't want to bite off more than you can chew.

5.Ignore that little voice inside

       You might sometimes hear a little voice in your head that tells you you're not happy or that something has to change. This little trouble maker can speak up at any time and throw the Spanner of Confusion in the works, and it has only one thing on its mind-to take you out of your comfort zone and make you change.

       Imagine if everyone went around listening to what they really wanted and acted on it-what a mess! No, best to ignore it and carry on with what you're doing.

49.The purpose of writing this passage is_________.

       A.to introduce ways to avoid change in 2009

       B.to attract the readers' interest in change in 2009

       C.to discuss whether people should change in 2009

       D.to tell the readers the news of American New President-Obama

50.Supposing you are safe, warm and comfortable now, you should______.

       A.set your expectations low                                   B.ignore any opportunities

       C.keep on running and don't look back             D.ignore that little voice inside

51.The underlined sentence "You don't want to bite off more than you can chew" implies      .

       A.you have big challenges to fight

       B.you are too small to eat too much food

       C.there are some big challenges you can't fight

       D.you are afraid of challenging some difficult tasks

52.The best way of dealing with that little voice inside is_______ .

       A.to change something at once

       B.to have a chat with the speaker

       C.to discuss it with the trouble maker

       D.to ignore it and go on with what you are doing

49---52   ABCD

Study carefully both the figure and the passage and answer the following questions:

  If a plane is standing on the ground, the air pressure on all its different parts is the same. This air pressure is increased or reduced when the plane moves.

  There are four forces which act on a plane as it flies through the air. The weight of the plane, because of the earth’s gravitation, a drawing force towards its centre, always pulls the plane downward. Drag prevents and delays the forward movement of the plane . Drag is caused by the opposite force the airframe or the body of the plane offers as it moves through the air and by the whirling or turning movements of air which form near edges of the lifting surfaces of the plane. Weight and drag are successfully defeated by thrust, a forceful forward movement, and lift, an upward air pressure on the wings of the plane. Thrust is provided or supplied by the engines which drive the plane forward. As the plane moves forward, the air flowing over the wings produces lift to raise the plane off the ground , and keep it in the air.

  The upper surface of a plane wing is made a rounded line like thisÉ at the leading edge while the under surface is almost flat to give the highest lift/drag ratio(such as 2:1 or 3:2.) . A rounded nose smoothly rounded top and a sharp tail is known as aerofoil (翼型)shape or the shape of the wings , the fin or tail plane of a plane. This particular shape makes air flow faster and farther over the wing than under it. Pressure above the wing is reduced and the wing is given lift. The amount of lift increases with the speed of the plane.

1. When the plane is standing on the ground the pressure on its upper surface is     that of its under surface.

A. the same as B. different from C. larger than D. smaller than

2. When the plane moves , the air pressure on its body is     

A. the same   B. changing C. unchanging D. neither A nor B nor C

3. When the plane is flying, the four forces are acting on it in     

A. the same direction    B. two different directions

C. three different directions D. four different directions

4. The backward force acting on the flying plane is     

A. the earth's gravitation B. drag C. lift D. thrust

5. In the picture, A, B, C, D stand for    

A. the earth's gravitation, drag, lift, thrust

B. drag, lift, thrust, the earth's gravitation

C. lift, thrust, the earth’s gravitation, drag

D. thrust, the earth’s gravitation, drag, lift

6. Drag is the opposite force of       

A. lift B. weight C. thrust D. whirling movements

7.   seems the most important of the four forces in making the plane take off and fly through the air.

A. lift B. weight C. thrust  D. the earth’s gravitation

8. Part M in the picture is called the   edge of the plane wing.

A. leading B. rounded C. sharp  D. upper

9. Aerofoil shape includes part     and part     in the picture.

A. M , N B. N , S C. S , D D. D , M

10. Which of the following statements is TRUE?

A. The faster the plane flies the easier it rises.

B. The higher Force D is the faster the plane goes up.

C. The stronger Force C is the faster the plane flies.

D. The sharp leading edge of the wing increases the air flow over it.

你将阅读的是一篇关于鲨鱼袭击的文章。有五处段落从文章中被取出了。请从A-F这六个选项中选出正确的选项填入空格中。选项中有一项是多余选项。

When I was eight, my parents, my younger brother, Stewart, and a girl called Margo Edwards, who was at school with us, went on holiday to Mozambique. One day, we took out a small rowing boat with an outboard motor on it, and went fishing on a lagoon at a place called San Martina.

Suddenly, as if out of nowhere, there was this disturbance in the water. I remember at first everyone thought it was a dolphin, but it wasn't leaping in and out of the water, and before long we could see this grey fin moving purposefully towards us.

It then circled around our rowing boat, and I remember my father saying: 'Well, I think that's a shark . . .'

My mother was screaming, and father was shouting obscenities at this thing, which he was to bash (痛击) back with one of the oars. I had never seen my parents in obvious terror before, and that's something which never leaves you.

My mother clutched the three of us around her. I remember she had a navy blue robe, with huge starfishes and sunflowers on it, and us three kids gratefully huddled together inside it.

As soon as we were in the fishing boat there was this almost hysterical laughter, and I remember feeling very cold, and being unable to stop trembling.

We all talked about it continually, too, and probably made out we were far braver than we were. And there was lots of re-enactment(表演). I remember that we made mud pools. One of us would be crawling along, playing the shark, and the others screaming and shouting: 'Kill the shark'.

A. For the longest time this thing kept circling around us, and hitting our rowing boat, while Dad continued fighting it off, stabbing at it with his oar, which was probably the worst thing to have done because it must have made the beast even angrier than it already was.

B. Our story went back to the town. It spread like wildfire. Everybody knew about it, and people talked about it endlessly. My father was regarded as a bit of a hero: Dad the sharkbasher. If he'd caught the thing, then I suppose he would have been completely heroic.

C. The shark became a legend in the town and there were many local fishermen who claimed to have seen it moving around the bay. But despite all the stories of sightings, nobody ever managed to catch the thing.

D. It was early evening when the motor stopped, and we were stranded (搁浅). We started to shout in the hope that somebody would hear us; we knew the sound could travel because of the water being very flat and calm.

E. Eventually, people in a fishing boat heard us screaming, and came alongside, and a fisherman tied our boat up to his. He was very careful, or he seemed to be, and he and my father handed first us kids, and then mother, through to his boat, and our rowing boat was towed behind.

F. This monster started bashing our boat, which began rocking from side to side. We were just terrified because the boat was by now rocking so much we thought we were going to be tipped into the water and bitten up by this thing. I remember assuming that we were going to die.

Energy-saving Finns invented the first ice skate more than 5,000 years ago, as a practical method of transport to make getting across frozen lakes less of a struggle.
The earliest skates would have been blades made from bones and are one of the oldest means of transport ever discovered —they may even have been essential survival tools.
Researchers at Manchester Metropolitan University have calculated that ice skates would have saved energy by 10 percent, and suggest that they were developed for practical use and were not used for recreation, as they are today.
They think the most likely birthplace of skating is southern Finland, where there are many icy lakes.
The scientists have put their theory to the test and made replica(复制品) skates modeled after examples held at the British Museum and the Fitzwilliam Museum in Cambridge.
Volunteers on ice rinks in the Alps had their heart rates, oxygen intake and skating speeds measured while they skated with the replica skates. From this experiment, re-searchers were able to calculate energy consumption and the efficiency of their skating. They discovered that skating over the land in ancient Fin-land would have saved 10 percent of people’s energy. The result is based on the fact that Finland has the highest concentration of lakes in the world. The ancient Finnish people could benefit more than others from developing this tool for transport.
In a time and environment in which the balance between energy taken from food and energy required to live was crucial; the least cost of energy might have helped humans survive in extreme conditions.
45. The first ice skate invented by the Finns was used for _____.
A. recreation                           B. transportation across lakes 
C. saving energy                       D. sports
46. The birthplace of skating might be southern Finland because _____.
A. there are many icy lakes there  
B. people need more oxygen to breathe in there
C. people feel tired easily there   
D. transportation there is more difficult
47. Scientists have experimented with replica skates and found that with those skates the ancient
Finnish people would have _____.
A. crossed a lot of lakes
B. saved 10 percent of energy when crossing the lakes
C. climbed the Alps easily 
D. otherwise wasted a lot of food and energy
48. It can be inferred from the story that _____.
A. the Finnish people were clever enough to invent the practical skates
B. there were a lot of lakes in ancient Finland
C. the living conditions were very hard for the ancient Finnish people
D. it was very cold in ancient times in Finland
