小博士:细心的同学们肯定发现了有些名词有单数(singular)和复数(plural)两种形式,而有些名词只有单数形式,这是怎么回事呢?让我来告诉你吧。英语中,名词按其所表示的事物的性质,可分为可数名词(countable noun)和不可数名词(uncountable noun),可数名词有复数形式,不可数名词一般没有复数形式。名词单数变复数的变化规则见下表。
比一比,看谁写的单词多!
1 直接加-s的单词有:________________________________.
2 加-es的单词有:___________________________________.
3 变y为i再加-es的单词有:__________________________.
4 不规则变化的单词有:_______________________________.
小博士:时间名词前可以用的介词在初中阶段学的主要有5个,可以用下面的速记歌来帮助学习。
年月之前要用“in”,遇到日期却用“on”。
上午下午又是“in”,某日上下午“on”帮忙。
正午、晚上用“at”,黎明、午夜也相宜。
时钟之前也是“它”,差分过秒不用“它”
说“差”要用介词“to”,说“过”要用“past”。
多说多练牢牢记,学好英语本事大。
记住了吗?那么就请信心十足地动手做下面的介词填空练习吗:
1 My birthday is ________Dec. 1st.
2 He was born ________ 1991.
3 The People's Republic of China(中华人民共和国) was founded (成立) ________ October 1st 1949.
4 It was happened(发生) ________ the morning of a cold day.
5 -Do you have time ________ Sunday evening?
-I'm afraid not. But I am free ________ the afternoon.
6 I usually go to bed ________ 9:00, but ________ weekends, I'm later.
7 New school year begins ________ September.
8 You can get cheap things ________ this time of year.
9 We enjoy ourselves ________ Children's Day.
同学们回想看看我们共学了哪些句型。本单元我们学习的是如何描述物体的位置。陈述句的格式为:sb. /sth.+be(not)+介词短语(方位)。如My book is(not)in my bag.我的书在/不在我的书包里。如果将这个句子改为一般疑问句就是将be动词提到句首,即为Is your book in your bag?寻问物体在哪儿要用到特殊疑问,结构为特殊疑问词where+一般疑问句。如Where is your book?在这里提醒同学们注意的是主谓一致。还是这三个例子,如果要说明的不只一本书,而是几本书,它们分别为“My books are in the bag. Are your books in your bag? Where are my books?”
试一试:你能将方框内恰当的动词形式填入对话空白处吗?如果填对了,说明你掌握了主谓一致的基本原则,如果有错,不必着急,可以向你的老师或者同学请教。
