Unit 6 If you go to the party, you’ll have a great time! Section A 【要点1】half 【经典练】用所给单词的适当形式填空： (1)Look at these strawberries. Half of them ________ (be) bad. (2)Half the building ________ (be) on fire last night. (1) are (2) was 【巧点拨】 ★“half+of+冠词／形容词性物主代词/指示代词等+名词”表示“一半的……”，其中of可以省略。如：half an hour半小时；half the men一半人员；Half (of) his food went bad. 他的一半的食物变质了。More than half (of) this land is his. 这块地的一大半是他的。 ★但是，“half+of+人称代词”中必须有介词of。如：Half of them went to the park yesterday. 昨天他们中一半人去了公园。 ★“half+of+形容词性物主代词/指示代词等+名词/人称代词”结构在句中作主语时，谓语动词的单复数与该结构中名词或人称代词的单复数保持一致。如：Half of this apple is bad. 这个苹果有半边是坏的。Half of these apples are bad. 这些苹果中有一半是坏的。 ★cut sth in half和cut sth into halves都可表示“把某物切成两半”。如：He cut the cake in half. 他把蛋糕切成两半。She cut the apple into halves. 她把苹果切成两半。 【要点2】too…to… 【经典练】完成句子： The boy is too young to go to school.
