Write and tell me if I'm to come. 如果我该来.请写信告诉我(相当于说:若我不必来.那就不用费心写信给 我了.) 2)whether可引导各种名词性从名和让步状语从句.if 只能引导宾语从句和条件状语从句.由if引导的从 句.首先要弄清楚是宾语从句.还是条件状语从句.然后再确定时态.若是引导条件状语从句.谓语动词 应用一般现在时代替一般将来时.例如: If you don't go soon, you’ll be late.如果你不马上去就会迟到. 当if引导一个非真实条件句时.从句的谓语动词应用过去式(如果是be, 则不论主语的人称和数.一律用 were),主句谓语动词用“would+动词原形 .例如: If everyone in the country knew first aid, many lives would be saved.如果每个国民都懂得急救.许 多生命就会得以挽救. 3)whether和if都可以与or no连用.但if与or not之间常需要用词语隔开.而whether与or not可连用.也可隔 开.例如: Can you tell me whether or not the train has left?(=Can you tell me whether the train has left or not?)你能告诉 我火车是否离开了吗? I don't care if your car breaks down or not .我不在乎你的汽车是否坏了. 4)下列情况.只用whether作引导词: 引导主语从句.同位语从句.表语从句.让步状语从句.例如: Whether he comes or not doesn't concern me.他来不来与我无关.

One night, a little swallow flew over the city. He was very  16  and wanted to have a good sleep in the city. When he saw the Statue of the Happy Prince (王子), he flew down and got ready to sleep   17  the feet of the Happy Prince.

Just as he was putting his head under his wing, some  18  fell on him. He thought it was raining. But when he looked  19 , he found the sky was  20  clear and bright that he could see lots of stars. Suddenly, he saw some tears were running down the Prince’s golden  21 .

22  are you crying?” asked the swallow.

“In a little street, there’s a poor house. From one of the windows, I see a woman  23  at a table. She’s sewing clothes for  24  women to wear. In a bed in the corner of the room, her little boy is sick. He’s asking for oranges, but his mother has only water to give him, so he is crying. The boy is so thirsty  25  the mother is so sad. Little swallow, will you please take her the  26  from the top of my sword (宝剑)?”

“It is very cold here and I am leaving for a warm place, but I will stay with you and do as you ask.”

The swallow took the bright red jewel from the Prince’s sword and flew away with it in his mouth. He flew into the woman’s room and  27  it beside the woman’s needle.

 28  he flew back, he told the Prince what he had done. “It ‘s strange,” he added, “It’s so cold but I feel quite  29  now.”

“That’s  30  you have done a good thing,” said the Prince. The little swallow began to think about this, and then he fell asleep.
