完成下列各题 A If you are writing or studyin9，it make

s very much difference where the light comes from．People who use books and pens every day have to be especially careful about the way the light shines on their work． Every house gets i ts light either from daylight through the windows--which is the very best to use--or from lamps or electricity：but whichever kind of light it is，the way it shines toward our book or work is a matter of great importance to the eyes． Take a book．sit with your back toward the window，and try to read．Your shadow(影子) falls all over the page and makes it almost as bad for your eyes as if you were in a dark room． Now turn around and face the window．The page is in the shadow again，while the bright light is in your eyes． Try sitting with you fight side toward the window．This is very well for reading，but if you were writing．the shadow of your hand would fall across the page and bother(打搅)you a little． There is just one other way：sit with your left side to the window．Now everything is perfect for reading and for writing，too． Whatever kind oi light is in the room，the rule about the right to sit is always the same． Which of the following is true？

A.How the light shines on our work is of much importance．

B.The way the light shines on your work makes no difference．

C.We needn't care about where the light comes from．

D.People can write or study under a light that comes from any direction．

完成下列各题 B The human body naturally prevents attempt（企图)to lose or gain weight

完成下列各题 B

The human body naturally prevents attempt(企图)to lose or gain weight．Thus the best way to lower your weight is to do some exercise daily．Although scientists don’t agree exactly how this works to lower the“setpoint”，they do know that exercise helps your body work with you and not against you in at least the following ways： 1．Exercise burns calories(卡路里)：if you walk two miles every day，you use an extra 1400 calories a week—and lose about a pound in two weeks． 2．Exercise helps to bum fat and build muscle：since muscle requires more calories than fat does，the more muscle you have，the faster you will bum calories． 3．Finally exercise speeds up your metabolism(新陈代谢)，not just while you’re exercising，but for several hours after exercise ends． A program of light-to-moderate exercise done for only a half-hour a day is enough to keep your“setpoint”lowered，and thus helps you lose weight and keep it off．If you need to lose more than five pounds，combine regular exercise with a moderate reduction in calories until you reach your goal(目标)． Scientists don’t________．

A.think exercise helps peoples bodies work against them

B.agree exercise helps to lower peoples weight

C.bilieve in exercise at all

D.think exercise helps peoples bodies work with them

完成下列各题 D

Clay is important because it is used to make containers of all kinds．Workers add water to soften clay．This makes it．easier to form. into shapes by machine．Then it is heated to a very high temperature．The result is a container that．will last for many years． In many countries，clay was formed from volcanoes(火山＞．This．kind of clay usually contains many minerals(矿物质)．So the fires to make containers from volcanic clay must be hotter that those used for non—volcanic clay．The fires may be as hot，as 1400℃．The high temperature should not be reached too fast SO that the containers can be dried slowly．You can add some materials to clay to gain desired results．For example，you can add sand to prevent tiny breaks or lines from forming on the surface of the final product．But you should not use sand from the coasts of oceans．Instead，you should use sand from rivers or other areas． Clay often exists in fields covered with some water．The clay will be found about one meter below the ground．．River banks often also have clay about one meter or less under the surface．Clay is very shiny when it is wet．You can also take some of the material and add enough water to it．Then press it in your．hands until it is about the size of an egg．It is probably clay if it holds together when you stop pressing． What’s the difference between volcanic clay and non-volcanic day？

A.Volcanic clay call be found in very few countries．

B.Non-volcanic clay can be dried more quickly．

C.Non-volcanic clay makes better containers．

D.Volcanic e]ay usually has more minerals．

完成下列各题 B Light travels at a speed which is about a million

times faster than the speed of sound．In one second，light travels about 300，000km．But sound travels only 344m．You can get some idea of this difference by watching the start of a race．If you stand some distance away from the starter，you can see smoke comes from his gun before the sound reaches your ears． This great speed of light gives US some strange facts．Sunlight takes about 8 minutes to reach US．If you look at the light of the moon tonight，remember that the light left the moon 1．3 seconds before it reached you．The nearest star is so far away that the light which you can see from it t0—night started to travel towards you four years ago at a speed of nearly 2 million km per minute．In some case，the light from one of tonight’s stars started on its journey to you before you were born． Thus，if you want to be honest，you cant say“The stars are shining to night”？You have to say“The stars look pretty．They were shining four years ago but their light has just reached Earth”． Sunlight seems to________than the light of the moon．

A.be less powerfull

B.travel much quickly

C.move less quickly

D.have to travel a greater distance

完成下列各题 A The sea is very big. Look at a map of

the world. There is less land than sea. The sea covers three quarters of the world. The sea is very deep in some places. There is one spot, near Japan, where the sea is nearly 11 kilometres deep. The highest mountain in the world is about 9 kilometres high. If that mountain were put into the sea at that place, there would be 2 kilometres of water above it. If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers,which flow into the sea, carry salt from the land into the sea. Some parts of the sea are less salty than other parts. There is one sea, called the Dead Sea, which is very salty. Because it is very salty, swimmers cannot sink! Fish cannot live in the Dead Sea. In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are very small. It is hard to see them. Many fish live by eating these. The sea can be very cold. Divers, who dive deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear elopes made of metal. One spot of the sea near Japan is

A.nearly nine kilometres deep

B.almost eleven kilometres high

C.two kilometres above the highest mountain in the world

D.two kilometres deeper than the height of the world's highest mountain
