A.4点40分

B.4点45又4/11分

C.4点54又6/11分

D.4点57分

答案

参考答案:C

解析:[答案]C。解析:时针一小时走30度,每分钟走0.5度;分针1分钟走6度。四点半时,时针与分针的夹角是45度,则第一次成直线需要(180-45)÷(6-0.5)=24又6/11 分,即4点54又6/11 分时第一次成直线。

     A good way to pass an exam is to work hard every day in a year. You may fail in an exam if you are lazy

for most of the year and then work hard only a few days before the exam. If you want to be good at English,

you have to read stories in English, and to speak English as much as possible. A few days before the exam you

should go to bed early. Do not go to bed late at night studying. Before you start answering in the exam, read

carefully over the question papers, and try to understand the meaning of each question. When you have finished

your exam, read over your answers. Correct the mistakes if there are any and be sure that you don't miss

anything out.
