That afternoon Robbie came to visit me. He said he’d got something to cheer me up and

pretended it was the maths test that I missed.” Mr Banks says you can do it at home instead, “ he

said, but I knew he was joking. I didn’t think it was very funny, but he did! The next day, I was

48 pale and didn't have much energy, but I was feeling better. The day after that, I was able to

go back to school.

Can you believe my luck? I went to the yoga class to feel healthier and instead I caught a cold!

April 1st is a day on which, in some countries, people try to play jokes on others. If one

succeeds in joking with somebody, one laughs and says, "April Fool", and then the person who has

been joked with usual laughs, too.

One April 1st, a country bus was going on a countryside road. The road was so small and not

so straight that the driver had great trouble in driving along. When the bus slowed down and

stopped, he quickly turned his key again and again, looking very worried, but nothing happened.

Then he turned to the passengers with an unhappy look on his face and said, “This poor bus is

getting old and it isn’t going as well as it used to. There is one thing to do if we want to get home

before dark. I shall count three, and on the word ‘three’, I want you all to lean forward(前倾)

suddenly as hard as you can. That should get the bus started again. Now, all of you lean back as far

as you can in your seats and get ready.”

The passengers all followed the drivers words. They leaned back all at once and waited

quietly for the drivers number counting. Then the driver turned to his front and asked whether they

were ready. The passengers hardly had enough breath to answer “yes”.

“One! Two! Three!” counted the driver. The passengers all leaned forward suddenly and the

bus started up at a great speed.

surprise and then big laughter when the driver cried, “ April Fools”.

Electricity keeps us warm in winter, cool in summer, cooks our food, heats our water, cleans

our clothes and powers our TVs, radios, video games and computers. Electricity makes wonderful

things 66 .

Electricity can travel 67 through our bodies. Do you know why? Because electricity

moves quickly through water and the human body is 70 percent water!

Electricity can be very dangerous. What will happen 68 you get shocked? You will

find it hard to breathe, your 69 will stop beating and you will get burns and even 70 !

As electricity travels at the speed of light, it’s almost impossible for you to get rid of it if you

really get shocked. And, you should 71 try to touch anyone who’s been shocked with your

hands, because you can become part of the circuit as well!

It sounds terrible, and it is, but if you remember the 72 rules, you can always use

electricity safely:

● Never touch an electric appliance if you are stan ding in water or if i

D. Read the passage and answer the questions.（阅读短文，回答问题）

Every year on my birthday, from the time 1 turned 12, a white gardenia(栀子花) was

delivered to my house. No card ever came with it. Calls to the flower-shop were not helpful at all.

After a while I stopped trying to find out the senders name and was just pleased with the beautiful

white flower, in soft pink paper.

I never stopped imagining who the giver might be, though. Some of my happiest moments

were spent daydreaming about the sender. My mother encouraged these daydreams. She’d ask me

if I had been especially kind to someone. Perhaps it was one of my classmates. Perhaps it was the

old man. He lived across the street. I'd delivered his mail during the winter. As a girl, though, I had

more fun imagining that it might be a boy that I had met.

One month before my high school graduation, my father died. I was so sad that I became

completely uninterested in my upcoming graduation dance, and I didn’t care whether I had a new

dress or not. My mother, in her own sadness, however, would not let me miss any of those things.

She wanted her children to feel loved. In fact, my mother wanted her children to see themselves

much like the gardenia: lovely, strong and perfect, with perhaps a bit of mystery(神秘).

I got married at the age of 22. My mother died ten years after I was married. That was the

year the gardenia stopped coming.

80. Did the writer know the sender s name when she received a white gardenia for the first time?

81. Why did the writer think the old man might be the sender of the gardenia?

82. What did the writers mother do when she spent time daydreaming about the sender?

83. Why did the writer feel sad before her high school graduation?

85. How do you like the writer’s mother?
