句子成分和类型
1.主语：句子所陈述的对象。
2.谓语：主语发出的动作。一般是有动作意义的动词。
3.宾语：分为动词宾语和介词宾语，属于动作的承受者。
4.系动词：表示状态或状态变化的动词，没有实际的动作意义。如 be， 感官系动词(look， sound， smell， taste 和 feel)、保持类系动词(keep， stay 和 remain)、状态变化类系动词(become、get、turn 和 go)等。
5.表语：紧跟系动词后面的成分。
6.定语：修饰名词或代词的成分。
7.状语： 修饰形容词、副词、动词或句子的成分。
8.补语：分为宾语补足语和主语补足语。是对宾语和主语的补充说明，与其有主动或被动的逻辑关系。
例如：You should keep the room clean and tidy.
你应该让屋子保持干净整洁。
(You是主语， should keep是谓语，the room是宾语，clean and tidy是宾语补足语。)
This kind of food tastes delicious.
这种食物吃起来很可口。
(This kind of food是主语， tastes是系动词， delicious是表语。)
注意：主语、谓语、宾语、系动词、表语、补语是一个句子的主干成分;定语和状语是一个句子的修饰性成分，不是主干成分。
9.简单句的基本形式是由一个主语加一个谓语构成。
10.复合句由一个主句和一个或一个以上的从句构成。
11.两个或两个以上的简单句用并列连词连在一起构成的句子，叫做并列句，其基本结构是“简单句+并列连词+简单句”。

初二期末英语语法知识点总结归纳
宾语从句
结构：主语 + 谓语动词 + 宾语从句(主语 + 谓语动词 + 宾语/表语)
1、引导名词性从句的连接词
(1)that：没有含义，在宾语从句中不做成分
(2)whether/if：表示是否，宾语从句中不做成分。
(3)连接代词：what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)
连接副词：where, when, how, why(在宾语从句中做状语)
2、在做宾语从句的题目时应注意时态
(1)当主句是现在时态时，宾语从句可以根据需要使用任何时态。
(2)当主句是过去时态时，宾语从句必须是一种过去的时态。
(3)当表示客观事实或普遍真理的句子做宾语从句时，任何时候都用一般现在时。
say/speak/talk/tell
say：是最口语化的最普通的一个词，意为“说出”、“说道”，着重所说的话。如：
“I want to go there by bus” , he said . 他说，“我要坐汽车到那里去。”Please say it in English .请用英语说。
speak : “说话”，着重开口发声，不着重所说的内容，一般用作不及物动词 (即后面不能直接接宾语 ) 。如：Can you speak about him? 你能不能说说他的情况?I don’t like to speak like this. 我不喜欢这样说话。
speak 作及物动词解时，只能和某种语言等连用，表达在对话中恰当使用词汇的能力。
如：She speaks English well.她英语说得好。
talk : 与 speak 意义相近，也着重说话的动作，而不着重所说的话，因此，一般也只用作不及物动词，不过，talk 暗示话是对某人说的，有较强的对话意味，着重指连续地和别人谈话。如：I would like to talk to him about it . 我想跟他谈那件事。Old women like to talk with children.老年妇女喜欢和孩子们交谈。
tell : “告诉”,除较少情况外，一般后面总接双宾语。如：He’s telling me a story.他在给我讲故事。
tell a lie 撒谎 tell sb. to do sth. /tell sb. not to do sth 如：.Miss Zhao often tells us to study hard.

【用法】用于询问某人有什么病或某人遇到什么麻烦、问题其后跟询问对象时， 与介词with连用。即：

— What’s the matter with you ? — I have a bad cold.
2. I had a cold.我感冒了。 have a cold=catch a cold=have the flu感冒
have a fever 发烧 have a cough咳嗽 have a stomachache胃疼，肚子疼 have a toothache牙疼 have a headache头疼

advise sb.to do sth.和advise sb.doing sth.的区别

advise sb.to do sth建议某人做某事
advise doing sth.建议做某事
如：He advised going to the movie.他建议去看电影.
He advised us to go to the movie.他建议我们去看电影.
请看下面这道题，该选哪个答案?是advise doing还是advise to do?
The husband advised_________to the south, but his wife advised him_________up the idea.
A. moving, givingB. to move, to giveC. moving, to giveD. to move, giving
【分析】此题容易误选A，因为许多学生都记住了“advise后接动词要用动名词而不用不定式”这一搭配规则。但此“规则”的表述是不准确的，准确的说法应该是：advise后接动词作宾语时，要用动名词，不用不定式;但若其后接的动词前有宾语，此动词用作宾语补足语时，则此动词要用不定式。即说advise doing sth (建议做某事)或advise sb to do sth (建议某人做某事)。类似情况的还有allow(允许)，permit(允许)，forbid(禁止)等动词，即：
allow doing sth允许做某事，allow sb to do sth允许某人做某事;
permit doing sth允许做某事，permit sb to do sth允许某人做某事;
forbid doing sth禁止做某事，forbid sb to do sth禁止某人做某事。
顺便说一句，要特别注意以上各句型后一结构的被动语态形式，如：
We don’t allow smoking in the lab.我们不准在实验室吸烟。
We don’t allow people to smoke in the lab.我们不准人们在实验室吸烟。
People are not allowed to smoke in the lab.人们不准在实验室吸烟。
