介词后面的名词（或相当于名词的其它词）叫做介词的宾语。

介词和介词宾语合称为介词短语。

介词短语在句中可作壮语、定语或表语。

介词如: in 在…里面on在…上面under在…下面等。

in the classroom in the tree in the hallon the road on the desk on the floorunder the table under the bed under the chair2.连词：连词是用来连接词与词、短语与短语、句子与句子等的词叫连词。

连词是一种虚词，在句子中不能单独作句子成分。

连词分两类：一类叫等立连词，另一类叫从属连词。

(1). 等立连词是用来连接同等的词、词组和分句的。

等立连词有许多我们现在只学到了and和but，其他的以后学到再介绍。

如：A and B ; blue and white ；an apple and a banana; a car and a bus;Lucy and Ben ; Ben and Kitty ;This is a lorry and that’s a drill.I like dolls and you like robots.(2). 从属连词是用来引起从句的、从属连词又分为1) 引起名词性从句的连接词，如：if ，that 等。

2）引起壮语从句的连接词，如：when ， after ，befare等。

以后会逐渐学到再介绍。

3.感叹词: 表示说话人的某种感情(惊讶,高兴,痛苦等)的词叫感叹词。

感叹词后常用感叹号。

常用的感叹词有：oh（表示惊奇或痛苦），ah（表示惊奇或满意），hello（常被用来打招呼相当于汉语的“喂！”），well（表示惊讶，无奈）如： you Mary?练习：翻译下列词组1.在桌子上面2.在树下面3.在椅子上面4.在盒子里面5.在黑板上6.在书里7.在脸上 8.在公共汽车上9.一只猫和一只狗. 10.又小又胖答案：1. on the desk 2. under the tree 3. on the desk 4. in the box5. on the blackboard6. in the book7. on the face8. on the bus9. a cat and a dog 10. small and fat(四) 单数句和复数句：口诀：单数句子变，变化规则要记住。

名词代词要变化，am, is要变are。

this, that变成啥，these, those来替它。

he, she, it要变啥，全部变they不用怕。

I要变we莫落下，名词后面把s/es加。

名前冠词去掉它，其余成分原样加。

具体注意下面的六要素：1．单数主格人称代词要变成相应的复数主格人称代词，即I→we；you→you；she, he, it→th ey。

如：She is a girl.→They are girls.2． am, is要变为are。

如：I'm a student. →We are students.3．不定冠词a, an要去掉。

如：He is a boy. →They are boys.4．普通单数名词要变为复数形式。

如：It is a cat. →They are cats.5．指示代词this, that要变为these, those。

如：This is a book.→These are books.6．man, woman作定语修饰可数名词时，要在 "数"上与被修饰名词保持一致。

但其他名词修饰名词表示 "性质"时，不作变化。

如：He is a man doctor.→They are men doctors.This is an apple tree.→They are apple trees.单复数相互转换，每空一词(含缩写)。

1. The woman is a nurse.(改为复数句)The _________ _________ _________.2. There are some old cars.(改为单数句)There _________ _________ old _________.3. He has a new book.(改为复数句)_________ _________ new _________.4. Are these your chicks (改为单数句)_______ _______ your _______5. Is there a sheep in the playground(改为复数句)________ there ________ ________ in the playground?(五)一般疑问句及特殊疑问句句子基本是：简单陈述句，由简单陈述句转变成肯定句，否定句，疑问句。

疑问句是用来提出问题。

英语中有四种疑问句: 一般疑问句、特殊疑问句、选择疑问句和反意疑问句。

我们现在已经接触到了前两种疑问句。

后两种疑问句以后我们还会学到.一.一般疑问句：英语中要用 yes和no 来回答的疑问句叫一般疑问句。

Do you like to eat applesYes，we do. /No，we don’t.二. 祈使句：表示请求、命令、建议或劝告等的句子叫祈使句，主语you常省略。

1、肯定形式：一般以动词原形开头。

Open the door, please.2、否定形式：在句首谓语动词前加Don't。

Don't be late for class.三特殊疑问句（又叫wh-question）用特殊疑问词来提出问题的疑问句叫作特殊疑问句。

特殊疑问词一般要放在句首。
