定义（define）简单句simple sentence,并列句compound sentence

如果你英文不错的话，其实谷歌一下看英文的网页就有的。
不过，要完全看懂的话(而且还不看字典)，其实要学过英文语法的。

Simple Sentence: A sentence that only has one independent clause, it contains one subject and one verb, it can express a complete idea.
例子：I like to play basketball. (我喜欢打篮球。一个主语一个谓语对否?)但是其实，还可以是Sam and I like to play baskeball. (”我和Sam喜欢打篮球“也是个simple sentence.)

Compound Sentence: A compound sentence is a sentence containing two independent clauses joined by a coordinator.
例子：He screamed for help because a dog was barking at him. (他呼声喊救命因为一只狗对他吠了。) 这里，有个连词，所以是compound sentence，其实就是两个simple sentence 用连词(conjunction)连在一起

Complex Sentence: Complex sentence is a sentence containing an independent clause joined by one or more dependent clauses.
例子：The book which I borrowed you yesterday was stolen. (我昨天借你的书被偷了。)
在这里，which引入了个dependent clause(在这个句子相当于定语，其实我不知道dependent clause 用在定语以外的方法，应该没有吧)

如果需要其他的翻译、句子或帮助的话，我可以提供帮助。
