Many changes have taken place in Moonlight Town over the years.这些年月光城发生了很多变化。三点剖析一、考点1. 现在完成时1). 构成形式：sb. have/ha
10、s done2). 现在完成时用法： 表示过去发生的或已经完成的某一动作对现在造成的影响或结果。 表示动作或状态在过去已经开始，持续到现在，也许还要持续下去，常和for, since连用。3). 动词过去分词变化规律： 一般情况下，直接在动词词尾加 ed 以 “e”结尾的动词，在词尾加d 以辅音字母+y结尾的动词，将 y变成 i 再加ed 重读闭音节结尾，末尾只有一个辅音字母，双写辅音字母，再加ed 其他不规则变化4). 相关句型 一般疑问句：Have/Has +主语+done？ 否定句：主语+have/has + not +done2. since的用法1). since作介词时，意为“从以
11、来”。since+ 时间点表示一段时间，常与完成时态连用，相当于for+一段时间。例句： I have lived here since 5 years ago.=I have lived here for 5 years.自从五年前我就住在这儿。2). since作连词时，还可引导时间状语从句。通常主句用现在完成时，从句用一般过去时。例句： Uncle Wang has worked at this factory since he came to this city.自从到这个城市以来，王叔叔一直在这个工厂工作。二、易错点1. happen & take place1). happen表示
12、“发生”，通常指未准备地发生或偶然发生。例句：The accident happened at about 10.事故大约发生在10点钟。2). take place通常指预先安排好要发生的事，因此在汉语中除翻译为“发生”外，还译为“举行”。例句：The meeting will take place on Sunday.会议将于星期日举行。Great changes have taken place here since last year.自去年以来，这里发生了巨大变化。3). happen & take place都属于不及物动词，因此既不能带宾语，也不能用被动语态。2. get use
13、d to和used to do 1). get used to意为“习惯于”，与be used to同义。to为介词，后面跟代词、名词或动名词。例句：His father gets used to getting up early.他父亲习惯于早起。2). used to do sth表示“过去常常做某事”，to是不定式符号，后接动词原形。used to本身就是过去时态，没有人与数的变化，暗含“现在已不再这样”之意。be used to do sth表示“被用来做某事”，是useto do sth的被动语态。题模精选题模一：Unit 1 词汇应用例1.1.1 Last Thursday whe
