These days, cars are designed using computers． Let’s look at how a new car is created．
First, several 16 talk about the new car and any good ideas that they have． Then they sit down at their computers and 17 many sketches． The best two or three drawings are chosen and then more detailed drawings of 18 are developed on the computer． You can change the size, shape or color of any part on the computer to see 19 the car would look like and then you can choose the best design．
Both the inside and the outside of the car have to be designed． Part of the inside of the car is 20 so that the designers can sit in it． They can feel if there is enough 21 inside and if they can reach 22 ． Then some cars are built—there are more than 15, 000 parts of a car to 23 ．
When everything is known to be 24 , the cars are made in the factory． Again, computers are used to make sure that all the parts are 25 as they are needed． The factory usually stays open all through the night so that the car production never stops．

III．阅读理解。（共15小题，每小题2分，计30分。）
A
Astronauts have already visited the moon and lived on space stations． They’ve never been to another planet, but they might visit Mars soon． Astronauts will spend about six months getting to the planet, then about two years on the planet and about six months traveling back to the earth． They’ll be away from the earth for about three years, so they’ll need much food．
It’s very expensive to take food into space． It costs about 120, 000 dollars to carry something that weighs one kilo, so an apple on Mars could cost 20, 000 dollars!
Of course, they will need to take much food with them to feed the astronauts for three years． This amount of fresh food can’t stay fresh, and it is very expensive to take, so they need to find food that is not very heavy．
At the moment, astronauts in space stations eat dried food． It’s very light, so it doesn’t cost much money to carry it into space．
However, astronauts will stay healthier and happier if they eat fresh food． In the future, astronauts on Mars may grow vegetables like carrots and lettuce．
Astronauts on Mars will probably have special machines． They’ll use these machines to change beans into food that tastes like meat or cheese． They probably won’t eat real meat or cheese because it won’t be possible to keep animals in space．
26．Which planet do the astronauts plan to go to next?
A．Mars． B．Space． C．The moon． D．The sun．
27．How long will it take to get to Mars?
A．About three years． B．About two years．
C．About six months． D．About thirty months．
28．Why do the astronauts eat dried food?
A．Because it is cheap to carry． B．Because it is cheap to buy．
C．Because it is very healthy． D．Because it is easy to buy．
29．What may astronauts do in the future?
A．Eat only dried food． B．Grow some fresh vegetables on Mars．
C．Grow food in their spacecraft． D．Spend much money to carry food．
30．What will astronauts get from beans?
A．Apples． B．Food that tastes like meat or cheese．
C．Real meat and cheese． D．Animals．
