语法精选 1. need 需要
need意为“需要”，既可用作实义动词，也可用作情态动词。need用作实义动词时，它的单数第三人称形式为needs，后面可跟名词、代词和带to的不定式等作宾语。如：
The boy doesn’t need help. 这个男孩不需要帮助。
need用作情态动词时，后面跟动词原形。如： They needn’t water the flowers again. 他们不再需要浇花。
2. in twenty years’ time二十年之后
“in+一段时间”表示“一段时间之后”，常用于将来时。可以用 how soon 来提问。如： —How soon will you be back? 你多久回来？ —In a week. 一个星期之后。
3. not only...but also... 不仅……而且……
not only...but also...是一个连词词组，意为“不仅……而且……”，连接两个并列成分。当连接两个并列的主语时，谓语动词要和邻近的主语在人称和数上保持一致。如：
①He can not only dance but also sing. 他不仅会跳舞而且会唱歌。
②Not only John but also his parents are going to watch the basketball match tomorrow. 不仅是约翰，而且他的父母也将去看明天的篮球赛。 4. as well 也
as well表示“也；又”，常用于句尾。如：
