　　One morning, when we had been riding on our bikes for five hours, we came to a bridge where the railway crossed a pond (池塘). For 30 feet there was nothing but the widely-spaced wooden sleepers(枕木)under our wheels, and nothing to stop us falling into the steaming pond below if we lost our balance. Right under the bridge lay the body of a dead cow. I watched Mat as he came near to the bridge and rode straight over, without even slowing down. I stopped.

　　‘What's up?’ he cried out from the other side.

　　‘I'm not riding over that thing, if I slip(滑), I'll be in there with that cow’.

　　‘There is nothing to it. I just did it, didn't I?’

　　‘You're strong and taller. My feet don't touch the ground. You do it for me. ’

　　Mat said strength didn't come into it and rode off. I knew he would give me at least an hour before coming to help. The sun burned my face, sweat ran off my forehead into my eyes and stuck my blouse to my body. Try myself rather than wait for Mat to help. I rode back to get a good run-up and over I went. Mat was that right: all the difficulties were in the mind.

[　　]

A．there was a 30 feet drop to the water below

C．the cow was harmless because it was dead

[　　]

A．didn't know that he could do to help her

Last week, I bought an alarm system(报警系统) for about $ 450. It consisted of a control unit with three other small units. I put the control unit in the sitting room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 491, the last three numbers of our telephone number.

Now I must explain how the alarm works:

1. There is a power siren(警报器) in the control unit. It makes a very loud noise.

2. Each of the small units sends out beams(光束) or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise that you can hear 50 meters away.

3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.

That might I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10a.m., I woke up and heard the siren(警报).

“There must be a burglar in the house,” Mary said. “What shall we do?”

“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”

I went downstairs quietly. When I reached the living room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, re-set the alarm and went back to bed.

About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’ m going downstairs to see what’s wrong.”

I went down into the living room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (蜥蜴) disappear behind the curtains.

“Oh!” I said to myself. “That’s our burglar.”

When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards.

Well, I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
