     When you go to see a doctor, he will write you a note to take to the chemist for some medicine.

Chemists are usually good at reading doctors' notes. But sometimes doctors write too badly and even

the chemists cannot read them.

     One day a man wrote to a doctor to invite him to have dinner at his house. The doctor wrote a reply,

but he wrote too badly and the man could not read it.

     “What shall I do?" he asked his wife. “I don't know whether he is going to come or not. l don't want

to call him and say that I don't understand him. "

      His wife thought for a while and then she had an idea. "Take it to the chemist," she said. "He will be

able to read it for us. "

    "Thank you," said her husband. "That's a good idea. "

     He went to the chemist's shop and gave the doctor's "note" to him. The chemist looked at it for a long

time.

    "Could you wait a moment, sir?" he said. Then he went to the back of his shop. After a few minutes

he came back, carrying a large bottle. He gave the bottle to the man.

     "Take one spoonful every day," he said.

l. What did the doctor do when he was invited to have dinner? 

A. He said he would come on time.

B. He wrote the man a reply.

C. He was very glad.

D. He wrote a note to the chemist.

2. Why couldn't the man understand the '6note"?  

A. Because the doctor wrote badly.

B. Because the man didn't know much about medicine.

C. Because the doctor didn't like to go.

D. Because the man never went to school.

3. The wife wanted her husband to ______. 

A. call the doctor to have dinner with them

B. go to the chemist and get some medicine

C. take the reply to the chemist for help

D. read it again

4. In this story,  the word " chemist " means "_____" in Chinese. 

A. 护士

B. No, he did.

C. Yes, he didn't.        

D. No, he didn't.

如图所示,某空间内存在着正交的匀强电场和匀强磁场,电场方向水平向右,磁场方向垂直于纸面向里。一段光滑绝缘的圆弧轨道AC固定在场中,圆弧所在平面与电场平行,圆弧的圆心为O,半径R=1.8m,连线OA在竖直方向上,圆弧所对应的圆心角θ=37°。现有一质量m=3.6×10-4 kg、电荷量q=9.0×10-4 C的带正电的小球(视为质点),以v0=4.0m/s的速度沿水平方向由A点射入圆弧轨道,一段时间后小球从C点离开圆弧轨道。小球离开圆弧轨道后在场中做匀速直线运动。不计空气阻力,sin37°=0.6,cos37°=0.8。求:

(1)匀强电场场强E的大小;

(2)小球刚射入圆弧轨道瞬间对轨道压力的大小。
