问题 单项选择题

甲、乙两个服装厂每个工人和设备都能全力生产同一规格的西服。甲厂每月用(作图)的时间生产上衣,(作图)的时间生产裤子,全月恰好生产900套西服;乙厂每月用(作图)的时间生产上衣,(作图)的时间生产裤子,全月恰好生产1200套西服。现在两厂联合生产,尽量发挥各自特长多生产西服,那么现在每月比过去多生产西服多少套?()

A.30

B.40

C.50

D.60

答案

参考答案:D

解析:

两厂联合生产,尽量发挥各自特长,安排乙厂全力生产上衣。由于乙厂用(作图)月生产1200件上衣,那么乙厂全月可生产上衣:1200÷(作图)=2100件。同时,安排甲厂全力生产裤子,则甲厂全月可生产裤子:900÷(作图)=2250条。为了配套生产,甲厂先全力生产2100条裤子,这需要2100÷2250=(作图)月,然后甲厂再用(作图)月生产西服900×(作图)=60套,故现在比原来每月多生产2100+60-(900+1200)=60套。

根据短文内容,判断下列句子的正(T)与误(F)。

     One day a snake was looking for food. She found a hole and went into it. "Hooray!" It was a house for mice.

She said to herself happily. There, she saw some little babies of mice. "They are good dinner for me!" 

     She came to them and asked, "Where are your parents?" The babies answered, "They went out for food."

"Food? Good!" said the snake. "Come on and listen to me. I came here to see your parents and tell them not to

steal the people's grain any longer or I will kill you all." The little mice worried about their own safety. "Don't be

afraid, my body is like the hole. It is a safe place. When I open my mouth, you can come into it one by one.

Then we will wait for your parents coming back. Are you clear?" The little babies came into the snake from her

mouth one by one.

     A moment later, the mice's parents came back with some grain. Just then they found a snake in their room.

"Who are you? Why did you come into our house?" "Where are our babies?" asked the mice's parents. The snake

answered coolly, "I am a judge of the people. I knew you did a lot of bad deeds. You often steal lots of

foodstuff of the people. Today, I came to sentence you to death. Your babies have been in my body. Don't you

want to see them?" With these words, the snake flew at the mice.
