Unit 3 Topic 1 同步练习 2024-2025学年仁爱科普版八年级英语上册

Unit3 Topic1 语法快递:小议“used to” used to 意为“过去常常;曾经”,其中to是不定式符号。“used to +动词原形”意为“过去经常做某事”,它强调“过去的习惯(过去经常反复发生的动作)或状态(现在已经不复存在)”,它只是一种形式,即过去式,可用于所有人称,没有人称和数的变化。 如: Li Ming used to be a doctor,but now he is a worker. 李明过去是一名医生,但是现在他是一名工人。 used to 构成否定式和疑问式时,通常有两种方法:即借助助动词did或直接将used用作助动词。其否定式是didn't use to或used not to。 如: Did you use to paint by the river.你过去常在河边画画吗? She didn't use to/used not to get up early.她过去不习惯于早起。 语法延伸 (1) be used to doing sth的意思是“习惯于做某事。”其中to是介词,后可接名词、代词或动名词等。表示某种状态,并没有特指过去习惯。如:I am used to listening to music now.我现在习惯听音乐了。 (2) become/get used to doing sth. 侧重于“变得习惯做某事”,它表示动作。 be used to doing…与get used to doing…一般可以互换。 (3) be used to意为“被用来……”,是动词use的被动语态,其中to是动词不定式符号,后接动词原形。如 A hammer is used to drive nails.锤子是用来钉钉子的。 学以致用 选择适当的短语并用其适当形式填空。 1. There_ be a lake near the river.(used to/be used to) 2. Wood can_ make desks.(used to/be used to) 3. I_ drinking a cup of water before going to bed.(used to/be used to) 词汇集锦 such as和for example两者都可以表示“例如”。但用法有所不同。 1. such as用来列举事物时,一般列举同类人或事物中的几个例子。插在被列举的事物和前面的名词之间。as后不可有逗号。 2. for example用来举例说明某一论点或情况,一般只列举同类人或物中的“一个”为例,做插入语,用逗号与句子其他成分隔开,可位于句首、句中或句末。 1.
