答案

第一题一个句子不能同时有几个谓语动词,故用动名词形式.
第二题如果是needs也可以选,应该用第三人称单数现在时.
“need”作为实义动词时,通常用法是
人＋need ＋to do 物＋need ＋doing 物＋need ＋to be done 例如：The room needs cleaning = The room needs to be cleaned.房间需要打扫了.另外,“need”作实义动词时后还可以直接跟名词.请看下面的例子：It is a question that needs very careful consideration．这是一个需要慎重考虑的问题 很简单的方法区别情态动词与实义动词：当need为情态动词时,意思是“必要”,否定为"needn't",后面大多接动词原形,表示动作； 当need为实义动词时,意思是“需要”,否定为"don't need",后面大多跟名词.
