4、 years since I became an English teacher. 我成为英语老师有两年了。 （2、）Since 和for区别、Since +时间点，具体时间“自从、以来，从、以后” 用来说明动作起始时间I have been in Beijing since 2010. 、For + 时间段，用来说明动作延续时间长度，因此句中的谓语动词，也应该是延续性动词。I have been in Beijing for one year。We have learnt English for about three years. I have been here for 3 days.
5、(对) I have arrived here for 3 days.（误）6、 18、either; too; also; as well 的区别（1）、as well常用作状语,作“又；也”解,相当于too或also,常位于句末,无须用逗号与句子分开.如： I am going to London and my sister is going as well（going,too）.（2）、as well 可以直接用于just后,用作应答语（可视为Its just as well、的省略）,作“幸亏,幸而；无妨；没关系”解.如： We were too late to see the fil
6、m.Just as well、I hear it isnt very good. （3）、also，either与too三者都是“也”的意思，also ,too 用于肯定句，其中also用于句中，too用于句尾，且前面有逗号；either用于否定句,且前面有逗号。例如：His father is a doctor; his mother is also a doctor.His father is a doctor; his mother is a doctor, too.His father isnt a doctor; his mother isnt a doctor, either.句型

9、定句在助动词have/ has 后加not ； 疑问句则把助动词Have/ Has 提放到主语之前。如：I have worked here for ten years . She hasnt been to the Great Wall . Have you been to Beijing ?3、现在完成时态的用法 （1）、表示过去某时刻发生的动作对现在造成的影响或结果，常与already , yet , just , ever , never.before , this morning , now , today , so far , in the last/ past+时间段、over
10、+时间段, recently ，by+现在时间等连用 如：Tom has already finished his homework. We have had two classes this morning. （2）、表示从过去某一时刻开始，一直延续到现在的动作或状态，常与for 引导的一段时间或since 引导的时间点或过去时间状语从句连用。如：Mr Green has lived in China for five months. Mr Green has lived in China since five months ago. Mr Green has lived in China
11、since he came to China.4、have/ has been to 与 have/ has gone to 区别 （1）、 have/ has been to 表曾去过某地（现在已不在该地），其后可接表次数的时间名词。如：Have they been to Emei Mountain? （2）、have/ has gone to 表示去某地了（现在不在说话的现场），其后不能用任何时间名词。如：Where is Jim ? He has gone to the library.（3）、have/ has been in /at表曾在某地住过、停留过，其后常跟for 或since
12、引导的时间状语。如： I have been at that village for ten years.5、短暂性动词与延续性动词在完成时态中的运用（1）、在肯定句中，不能和for , since引导的时间状语连用，也不能用在how long引起的特殊疑问句中。 (2).凡是完成时态都表示，不知道也不管动作发生的具体时间,所以在使用现在完成时的句子里，不可以带有表示具体过去时间的状语，如：yesterday,lastweek(month,year,etc.),twoweeksago,in1999等；但常和有些副词连用，如：just,before,already,often,never,eve
13、r,notyet,always等等。 (3). 在以when提问的特殊疑问中不能用现在完成时。另外，ago不能用于现在完成时的句子里，因为它表示从现在算起的以前某个时间，属于表示具体过去时间的状语。但是可以用before 来表示以前的意义，因为它只表示以前，而不知什么时候的以前。（4）、大部分短暂性动词可以根据实际情况改为相应的延续性动词来表达相同或相近的意思，常用的列举如下：borrow /lendkeep buy have leave be away( from) die be dead join be in / be a member of get to know know begin
14、be on come be / live / stay put on wear catch a cold have a coldget/go to sleep/ fall asleep sleep, be asleep get up / wake up be upgo to school be at school get/ receive (接收）have hear from have a letter from finish be over go / come / arrive /get(到达)/reach be(in/at)(5)、句型1：It is / has been +时间段+sin
15、ce +句子（过去时态）It is five years since he came to China.句型2：Itswillbethefirsttimethat(第一次)： Its the first time Ive come here. 这是我第一次来这儿。【注意】一般过去时与现在完成时的区别 过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响；一般过去时常与具体的时间状语连用。试比较：Isawthisfilmyesterday.（强调看的动作发生过了，不涉及现在）Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了。）专心-专注-专业
