Simple, compound and complex sentences
A Exploring the rules
A simple sentence is made up of one independent clause which has one subject-verb combination.
简单句由一个包含一个主谓组合的独立分句组成。
简单句五种基本类型：
1.主语+不及物动词 （S+V）
2.主语+连系动词+表语 （S+V+P）
3. 主语+及物动词+宾语 （S+V+O）
4.主语+及物动词+间宾+直宾 （S+V+IO+DO）
5.主语+及物动词+宾语+宾补 （S+V+O+C）
A Exploring the rules
1. S + V（主语 + 不及物动词，无宾语）
谓语动词后面不能直接加宾语，可加状语（地点 / 时间）
例句：Many teens struggle.（许多青少年在苦苦拼搏。）
He grows up.（他长大了。）
2. S + V + P（主 + 系 + 表）
系动词 + 表语（名词/形容词，用来描述主语）
系动词：be 动词 (am/is/are/was/were)；感官：look/sound/smell/taste/feel；变化：become/get/grow/turn
例句：I feel upset.（我感到心烦。）
Her dream is a clear target.（她的理想是明确的目标。）
A Exploring the rules
3. S + V + O（主谓宾）
谓语是及物动词，后面必须接宾语
例句：We desire more freedom.（我们渴望更多自由。）
I set a study target.（我定下学习目标。）
4. S + V + IO + DO（主谓双宾：人 + 物）
动词后接间接宾语 (人) + 直接宾语 (物)
常用：give/buy/tell/send
例句：Parents buy us useful books. = Parents buy useful books for us.
（父母给我们买有用的书。）
A Exploring the rules
5. S + V + O + OC（主谓宾补）
宾补用来补充说明宾语，无宾补句子意思不完整
常用动词：ask/let/make/want/expect
例句：Parents expect us to achieve targets.
（父母期盼我们达成目标。）
A Exploring the rules
A compound sentence contains two or more main clauses. We use linking words such as and, or,but, so or for to link the clauses.
并列句包含两个或更多主句。我们使用连接词，如and、or、but、so或for来连接这些句子。
1. 表并列、顺承关系
常用：and、both…and…、not only…but also、neither…nor等
例句：We communicate patiently, and we solve family conflicts.
（我们耐心沟通，并且化解家庭矛盾。）
2. 表转折、对比关系
常用：but、yet、while等
例句：I want more free time, but my parents arrange extra lessons.
（我想要更多空闲，但父母安排了补课。）
A Exploring the rules
3. 表选择关系
常用：or、either…or…、otherwise、or else等
例句：Finish your homework, or you will get scolded.
（写完作业，不然你会挨批评。）
4. 表因果关系
常用：so、therefore、for（不能放句首，补充说明原因）等
例句：She cries often, for she struggles with great study stress.
（她时常落泪，因为她饱受学业压力困扰。）
A Exploring the rules
A Exploring the rules
A complex sentence contains one main clause and at least one subordinate clause. A subordinate clause can be the subject, predicative, object, attributive or adverbial of the sentence.
复合句包含一个主句和至少一个从句。从句可以充当句子的主语、表语、宾语、定语或状。
复合句：主句独立完整，从句不能单独成句，由从属连词引导、充当句子成分。
结构：主句 + 连词 + 从句
1. 状语从句
例句：I’m upset because parents push me hard.
（我很烦恼，因为父母逼我太紧。）
2. 宾语从句（that/why/how 引导）
例句：I think (that) we need more communication.
（我认为我们需要更多的沟通。）
