四、课文重难点

I. Important words & phrases

II.1.【教材原句】With the advancement in robotic technology, artificial limbs can now perform much more complex tasks and come closer to real human limbs.

随着机器人技术的进步,假肢现在可以执行更复杂的任务,更接近真实的人类肢体。

【归纳拓展】

“with+宾语+宾语补足语”构成的复合结构除了在句中作状语外,还可以作定语。主要结构如下:

①Seconds later, our lizard emerged from its tank with its old skin ______________ (flow) behind it. 

②Candidates will be matched with a task ______________ (base) on skill set. 

③With the young unable to afford to leave home and the old at risk of isolation(孤独), more families are choosing to live together. 

④With that thought _____________ mind, Pruitt came up with a plan and posted it on the community website. 

2.【教材原句】Not only can I do more, but I have also become more confident and outgoing.  

我不仅可以做得更多, 而且也变得更加自信和外向。 

【句式解构】否定词置于句首, 要用部分倒装语序, 即把谓语动词的一部分(助动词、情态动词或be动词)提到主语之前。这类否定词或含有否定意义的短语主要有: no, not, never, little, hardly, seldom, scarcely, barely, not until, neither. . . nor. . . , not only. . . but also. . . , no sooner. . . than. . . , hardly. . . when. . . , in no sense, in no way, in no case, by no means, on no account/consideration, at no time, under no circumstances等。

Not only can they make a much wider range of movements, but they can also be controlled directly by the brain and feed sensory information back into it.  

它们不仅可以做出更广泛的运动, 还可以被大脑直接控制, 并将感官信息反馈给大脑。

On no condition can we give up our dreams.  我们决不能放弃梦想。

Hardly had we left the dormitory the next morning when we realized we had left our map in the room.

第二天早上, 我们刚离开宿舍, 就意识到我们把地图忘在房间里了。

Not until he went through real hardship did he realize the love we have for our families is important.

直到经历了真正的苦难后，他才意识到我们对家人的爱是重要的。

(1)当not until位于句首时, not until所在的从句不倒装, 主句要倒装。

(2)not only. . . but also. . . 连接两个并列句且not only位于句首时, 前者倒装后者不倒装。
