答案

参考答案:(1)2007年电子产品可比产品成本降低额=1200×500-594000=6000(元)
降低率=6000÷(1200×500)=1%
(2)2007年电子产品计划成本降低额=1200×490-594000=-6000(元)
降低率=-6000÷(1200×490)=-1.02%
(3)2007年数码产品可比产品成本降低额=1100×400-434500=5500(元)
降低率=5500÷(1100×400)=1.25%
(4)2007年数码产品计划成本降低额=1100×390-434500=-5500(元)
降低率=-5500÷(1100×390)=-1.28%
(5)华夏公司2007年可比产品成本降低额=6000+5500=11500(元)
降低率=11500÷(1200×500+1100×400)=1.11%
(6)华夏公司2007年电子、数码两种产品计划成本降低额=-6000- 5500=-11500(元)
降低率=-11500÷(1200×490+1100×390)=-1.13%
(7)2007年机械设备计划成本降低额=600×200-123000=-3000(元)
降低率=-3000÷(600×200)=-2.5%
(8)2007年全部产品计划成本降低额=-6000-5500-3000=-14500(元)
降低率=-14500÷(1200×490+1100×390+600×200)=-1.28%

     A man was on the side of the road hitchhiking (搭便车) on a very dark night in the middle of a terrible

rainstorm, with no cars on the road. The storm was so strong that the man could hardly see a few feet

ahead of him. Suddenly, he saw a car come towards him and stop. The man, without thinking about it, got

in the car and closed the door and only then did he realize that there was nobody behind the steering wheel

(方向盘)!

     The car started to move very slowly. The man looked at the road and saw a curve (拐弯处) coming his

way. Terrified, he started to pray, begging for his life. He had not come out of shock when, just before the

car hit the curve, a hand suddenly appeared through the window and moved the wheel. The man, paralyzed

with fear, watched how the hand appeared every time the car was drawing near a curve. Finally, although

terrified, the man managed to open the door and jump out of the spooky car. Without looking back, the man

ran through the storm all the way to the nearest town. In a state of complete horror, the man walked into a

nearby bar and asked for two glasses of Scotch whisky.

     Then, still shaking with fright, he started telling everybody in the bar about the horrible experience he just

went through in the spooky car. Everyone in the bar listened in silence and became frightened, with hair

standing on end, when they realized the man was telling the truth because he was crying and he was certainly

not drunk!

     About half an hour later, two other young men walked into the same bar and one said to the other, "Hey,

there's a stupid man who jumped into the car while we were pushing it!"

1. When the car was first drawing near a curve, the man _____.

A. felt very curious

B. was extremely frightened

C. cried for help

D. remained as calm as possible

2. According to the passage, what made the man's experience believable?

A. His reasonable behavior.

B. His vivid description.

C. His plain appearance.

D. His honest attitude.

3. We can infer from the passage that _____.

A. it is unsafe for people to take a free ride

B. the man was telling a lie to his listeners

C. the car probably broke down on the way

D. the two young men were familiar with the man
