　　新东方在线新概念英语网为大家带来新概念2第28课重要句型语法，希望以下内容能够为大家的英语提供帮助!

　　重要句型语法

　　1、现在完成时

　　本课侧重的是现在完成时的标志性词语的用法。如：already/just/never/ever/yet。此外，还有一些标志性的时间状语或短语的用法。如：so far/up till/to now;three times;have been to/have gone to;since/for等。

　　三、课文主要语言点

　　Jasper White is one of those rare people who believes in ancient myths. 1)one of those who后面的谓语动词多用单数，复数也可以。但是，如果是the only one of who后面的谓语动词就只能用单数。 2)rare，稀有的、很少。其副词为rarely，表示很少，是否定副词。 3)believe in，相信、信任某人或某物。注意与believe(相信某人的话)的区别。 4)ancient，古代的、古老的。 5)myth，神话。

　　He has just bought a new house in the city, but ever since he moved in, he has had trouble with cars and their owners. 1)just是现在完成时的标志性词语。 2)ever since，自从。与since意思和用法相同，都是现在完成时的标志性词语。 3)have trouble with sth.，碰到…麻烦。如果have trouble后接动词，则采用in doing的形式，即have trouble in doing，其中的in一般都会省略。 4)owner，主人。源自动词own(拥有)。

　　When he returns home at night, he always finds that someone has parked a car outside his gate. 1)return home，回到家里。相当于come back home。 2)park a car，停车(车子熄火，人离开)。注意与stop a car的区别(暂停不熄火，人在车里)。

　　Because of this, he has not been able to get his own car into his garage even once. 1)because of，因为、由于。介词短语，后面只能接单词或短语，不能接句子。 2)be able to，得以。表示好不容易才能够。 3)get…into…，把…放到…。

　　Jasper has put up 'No Parking' signs outside his gate, but these have not had any effect. 1)put up，张贴。 2)No Doing，标牌用语，表示禁止。如No Spitting，禁止随地吐痰。 3)have an effect，有影响。如果要表示对…有影响，则采用have an effect on/upon…。

　　Now he has put an ugly stone head over the gate. It is one of the ugliest faces I have ever seen. It is one of the +最高级+复数名词+sb.+have/has ever done，这是某人...的等最…的...。其中，I have ever seen是作为faces的定语从句，省略了在从句中作宾语的关系代词that。

　　I asked him what it was and he told me that it was Medusa, the Gorgon. 1)what it was作为asked的宾语从句，所以要采用陈述句语序。 2)Medusa，美杜莎。希腊神话中的一个女妖，高哥(Gorgon)三女妖之一。她的头发都是蛇。据说她原是一位美丽的少女。

　　Jasper hopes that she will turn cars and their owners to stone. But none of them has been turned to stone yet! 1)turn…to…，把…变成...。 2)none of sb….yet，没有一个...。

　　四、读写重点

　　注意并列复合句的运用：He has just bought a new house in the city, but ever since he moved in, he has had trouble with cars and their owners. 句中的but引导的是第一层关系的并列句，然后在but分句中含有由ever since引导第二层关系的时间状语从句，所以整个句子为并列复合句
