答案

第一题,want是及物动词,需要的意思,所以直接接名词或动名词,例如“‘Your hair wants cutting,’ said the Hatter”(Lewis Carroll)
“‘你的头发需要剪一下,’海特说道”(刘易斯·卡罗尔)
第二题,题目意思是,那个在借记处的年长的图书管理员答应我,（只要）她记得谁最后借了这本书,就会把书给我.A.ever since,从那时到现在,B.much as 非常象,和…几乎一样,C.even though即使,D.if only 是只要的意思.
第三题,题目是被动结构,突出强调observation.换成正常语序为someone make observation(B)the children at the beginning and at the end of pre-school and first grade. 而一般用make observation of sth 表示“对某事物进行观察”.
第四题,因为恶劣天气,所有航班都被取消,他们只好改乘火车去那.所以要用被动语态,而又因为航班取消都现在情况造成了影响,所以要用现在完成时,综合考虑,所以要用被动现在完成时.
第五题,can'not help doing sth 是“禁不住做什么事”的意思,sb be skeptical of sth 表示对某事怀疑,suspicious是“可疑的,怀疑的”,主语必须是被怀疑的对象.
