I used to collect baseball cards.‎ used to do sth.是一个固定结构，意思是“过去经常做某事”，后面用动词原形，表示过去的某种经常性、习惯性的行为或者动作，并意味着这种动作目前已经不存在。‎ 肯定句：I used to play with my friends after school. 过去放学后我常常和朋友们一起玩。‎ 否定句：You didn’t use to like pop songs.=You usedn’t to like pop songs.‎ ‎ 你过去不喜欢流行歌曲。‎ 一般疑问句：Did your sister use to be quiet? = Used your sister to be quiet?‎ 你的妹妹过去常常是很安静吗？‎ there be句式：There used to be a lot of fishes in this river. 过去这条小河常常有许多鱼。‎ ‎【拓展】‎ ‎（1） be used to do something意思是“被用来做某事”，是动词短语use …to do的被动语态结构。例如：‎ Knives are used to cut things.小刀是用来切东西的。‎ ‎（2）be used to doing something意思是“习惯于做某事”，to后接动词-ing形式。例如：‎ My father is used to living in the village. 我爸爸习惯于住在村子里。‎ ‎3. All pets provide their owners with love and comfort in their lives.‎ provide为及物动词，意为“提供”。provide常与介词with或for连用，provide sb. with sth.表示“为某人提供某物”，其同意表达为 provide sth. for sb.。例如：‎ The Sun provides us with light and heat./ The Sun provides light and heat for us.‎ 太阳给我们提供光和热。‎ Sheep provide us with wool. /Sheep provide wool for us.‎ 羊供给我们羊毛。‎ ‎4.

But the girl was afraid to go home without selling one box of matches.‎ ‎（1）be afraid 之后可接不定式，也可接名词、代词或of doing sth. 表示“害怕做某事”或“不敢做某事”。例如：‎ She was afraid to tell you. 她害怕告诉你。‎ She is afraid of going out alone late at night. 她很怕深夜独自外出。‎ I’m afraid of the dog. 我怕狗。‎ ‎（2）但若要表示担心可能会发生某事，则只能用 be afraid of doing而不能用 be afraid to do。‎ 例如：‎ I’m afraid of being late for class. 我担心上课迟到。‎ ‎【拓展】‎ be afraid后可接that从句，表示“担心……”。例如：‎ He is afraid that his father will be unhappy. ‎ 他担心他的爸爸会不高兴。‎ ‎6. And then they felt too tired to work on Monday mornings.‎ too…to…意为“太……而不能”。它在结构形式上是肯定的，但意义上却表示否定含义，所以动词不定式符号to前不能再加not，只接动词原形即可，too后接形容词或副词原形。‎ 例如：‎ ‎ The book is too difficult to understand. 这本书难于理解。‎ ‎【拓展】‎ ‎(1 )在too…to…句型中，当动词不定式的动词是不及物动词，其后所跟的介词不能省略。‎ 例如：‎ ‎ The room is too small to live in. 这房间太小了不能住。‎ ‎ (2) 在too…to…句型中，当动词不定式的宾语实际上就是这个句子的主语时，动词不定式后面不能再加代词作宾语。‎ 例如：‎ ‎ The question is too difficult to answer. 这个问题太难了，无法回答。‎ ‎ (3) 在too…to…句型中，当动词不定式能确切说明动作执行者时，可以在动词不定式前面加上逻辑主语，即for sb.形式。例如：‎ ‎ The box is too heavy for him to carry. 箱子太沉了，他搬不动。‎ ‎ (4) 含too…to…的句子可以改写成so…that…句型，意为“如此……以至于……”。例如：‎ 5‎ ‎ He is too old to do hard work. =‎ ‎ He is so old that he can’t do hard work. 他年纪太大而不能干重活。‎ ‎ (5) 含too…to…的句子也可以用“not + 形容词/副词 + enough to do sth.”句型来替换，但注意要用原句中形容词或副词的反义词。例如：‎ ‎ He is too old to do hard work. =‎ ‎ He is not young enough to do hard work. 他年纪大了，不能做重活。‎ 句式精练 I.‎‎ 句型转换，按要求完成下列句子。‎ ‎1.
