重点句型归纳:
1.Neither is there pine nor apple in pineapple.
句型:neither...nor...表示“既不……也不……”。其含义是否定的,可连接任意两个并列的成份。
注意:
1)当neither…nor…连接两个主语时,也应遵循"Neither nor就近原则
2)连接并列的句子时,(因neither/nor都是否定意义的词)前后两句都用倒装语序。
2. That is why when the stars are out, they are visible, but when the lights are out, they are invisible.
句型:why引导表语从句
3.English is very difficult to learn.
句型:“主语+be+adj.+不定式”结构。
