【课文讲解】

①In 1858, a French engineer arrived in England with a plan.

plan for

twenty-one-mile 加连字符, 用单数, 是定语

②He said that

It 代表: to build a platform in the centre of the channel. 作形式主语

③serve as作为......来服务, 起......作用

it will serve as a swimming pool

④put forward(plan/suggestion)提出

bring forward

⑤suggest有两个意思

① 作为 “暗示” 意思时, 用法与其他的词相同

② 作为 “建议” 意思时, 则为虚拟语气, 后接动词是要用-ing形式, 后接that从句采用一种固定的用法: should+动词原形, should 可省略

insist 用法作坚持用时同suggest

文中: He suggested that a double railway tunnel should be built.

I suggested (that) he (should) go home. (that, should 都可省略)

又如: He suggested that I should go with him. 他建议我一定要跟他去.

     He insisted that I should stay to lunch. 他坚持要我留下来吃晚饭.

⑥draw in吸进

如用bring没有 drow in 形象,贴切

虚拟语气(非真实条件句)

1、与现在事实相反

2、与过去事实相反

其从句的使用 :

1、与现在事实相反, 用一般过去时

2、与过去事实相反, 用过去完成时, 此时主句格式为would have done

would/could/should 都可以

must have done对过去的推测

can't have done对过去的推测

情态动词加have done 表示对过去的推测

非谓语动词中的ing形式

1、表示其与主语是主动的关系

2、表示动作正在发生

非谓语动词中的ed形式表示其与主语是被动的关系
