Let’s look at how a new car is created.First, several 1 talk about the new car and any good ideas that they have. Then they sit down at their computers and 2 many sketches. The best two or three drawings are chosen and then more detailed drawings of 3 are developed on the computer. You can change the size, shape or colour of any part on the computer to see 4 the car would look 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 5 so that the designers can sit in it. They can feel if there is enough 6 inside and if they can reach 7 . Then some cars are built-there are more than 15000 parts of a car to 8 .When everything is know to be 9 , the cars are made in the factory. Again, computers are used to make sure that all the parts are 10 as they are needed. The factory usually stays open all through the night so that the car production never stops.1.

A rare B. electronic C. comfortable D. readyIn fall 2006, the National Basketball Association (NBA) started using basketballs made with synthetic, or man-made, material instead of leather(皮革). They made the change because they wanted every basketball they use to feel and bounce (弹起) the same. Not all leather balls are exactly alike in weight or how they bounce, but the synthetic balls are.However, some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones.Physics helped answer questions about why the new balls felt different. For example, the scientists studied friction(摩擦力)，which in this case affects the ability of a player to hold onto a ball. “The greater the friction, the better it will stick to his hand,” explains a scientist.Tests on both wet and dry balls showed that while the synthetic ball was easier to hold noto when dry, it had less friction and became much harder to hold noto when wet. That’s because sweat(汗水) stays on the surface of the synthetic balls but gets taken into the leather balls.The scientists also tested bounce and found that the logo(商标)printed on the new balls made their surface uneven(不平) and caused them to bounce a little strangely compared with the leather balls.In January, the NBA went back to using the leather balls. They aren’t perfect, but for now, that’s just the way the ball bounces.1. Why were the synthetic balls expected to be used in NBA according to the text?A. Because they are easier to control.B. Because they waste less material.C. Because they look exactly alike.D. Because they feel and bounce alike.2. The ball is easier to hold on to .A. when friction if greaterB. when friction is lessC. when it is heavierD. when it bounces strangely3. The synthetic ball bounces differently from the leather one mainly because .A. it is wetB. it is dryC. there’s a logo on itD. its weight remains the same4. It can be inferred(推断) from the text that .A. a synthetic ball takes in water faster than a leather ballB. a leather ball is more difficult to make than a synthetic oneC. a synthetic ball is more expensive than a leather ballD. a leather ball may increase its weight during a game5. The underlined word “They” in the last paragraph refers to .A. the synthetic ballsB. the leather ballsC. the ball playersD. the scientists组合训练（1）一、单项选择题1. －When your father to his new office?－Just this Monday.A. do; goB. did; goC. has; goneD. had; gone2. －My brother is a teacher.
