2. stay up 熬夜
stay up为固定短语,相当于不及物动词,意为"熬夜;不睡觉",与sit up同义。stay up late指"熬夜到很晚,迟睡"。
? He stayed up too late last night. 他昨天晚上熬夜到很晚。

? Don’t play tricks and jokes. 不要开玩笑。
7. By the time people realized that the story was a hoax,all of the spaghetti across the country had been sold out.
句中that引导的是宾语从句,作动词realized的宾语。
? I realize that it’s very necessary for us to learn English well.我意识到对我们来说学好英语非常有必要。

Once an Englishman named Jack Brown went to Russia for a holiday. He stayed there for several months and then came home again. Some of his friends visited him a few days after he got back."I had a very dangerous trip while I was in Russia,"Jack said to them."I wanted to see a friend of mine in the country and the bad weather made me very late. So I was still traveling through a forest in a sleigh(雪橇) when the sun went down. It was a long way from my friend’s house when about twenty wolves began to follow my sleigh. It was very dark in the forest. There was thick snow on the ground. It was cold, and there were no houses for miles and miles. First I heard the wolves. The noise was terrible! The horses heard them, too. They were frightened and began running faster. Then I saw long, gray forms among the trees, and soon the wolves were near us. They were running very fast, and they didn’t seem to get tired like the horses."
"What did you do?"one of Jack’s friends asked.
"When the wolves got very near,"Jack answered,"I put up my gun and shot the first wolf. The sleigh was moving about, but I hit the animal and killed it. Then all the other wolves stopped and ate it, so our sleigh got away from them for a few minutes."
"Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another of them, and the others stopped once more to eat it."
"The same thing happened again and again, and my horses became more and more tired and ran slower and slower until, after about two hours, only one wolf was still alive and following us."
"Wasn’t it too fat to run?"one of his friends asked.

It was a great pleasure for the family to move to a house with a very big garden. Betty and Tony could climb up trees, grow flowers and even play badminton. They liked to watch the birds flying among the trees in the garden. They even started to put food out to attract more birds.
Everything was fine for a few days until one afternoon there was a strange bumping noise on a window. Betty went outside and found a small bird dead on the grass. Its neck seemed to be broken. "It must have flown into the window." Tony said when his sister Betty called him to have a look. "Ah, yes, look here. You can see the mark where it hit the window. There are a couple of tiny feathers stuck on the window. "
"Poor thing!" Betty said.
During the next month, five more birds died in the same way. "Why would they fly to the windows? " They wondered. Finally they knew the truth. When the birds were flying, they couldn’t see into the rooms. All they saw was the reflection(倒影)of the garden. They thought that they were flying into trees because they saw trees reflected by the window.
"Something has to be done to save the birds." the parents decided.
At first, the family tried keeping curtains(窗帘) across the windows, but this made the room dark. Then they bought some strong black paper and cut out the shape of a hawk. They made six hawks ——one for each window. They stuck the hawks to the windows. They looked pretty and did not keep out much light. When the birds saw the hawks, they would fly away.
After that, there were no more dead birds. The family were much happier.
