1.B.这里已经有实义动词like了,所以只需用should加强语气,表"宁愿"的意思.2.B.同意swensky的解释. atof修饰的是knowledge,what引导的从句只是对food作用的进一步推导.knowledge一般为不可数名词,所以不用thoseof.

1。I_like a cup of coffee instead of orange juice, please。A need B should 选B should like =would like2 There are so many books for me to _,so I can not decide which one to_。A choose,choose from B choose from ,choose选B 第一空，choose from so many books 第二空，choose which one3 Today our knowledge of food and what it does for our bodies is far more advanced than _the old times。A those of B That of 选A,不同意realin 的说法，这里，what从句是一主语从句，试着恢复从句原来的语序：it does what for。。。。，这里可见，无论是knowledge或者food都不适合这一位置，故 ，our knowledge of food 和what 从句是并列的成分，选A。

第一题的意思是我要一杯咖啡，不要橘汁。答案：选B。 分析：need后不能直接接动词第二题的意思是有这么多书供我选择，我都不知道选哪本了。答案：选B。分析：choose from强调从一些事物中选出，而choose的意思是选择某一事物。第三题的意思是现今我们对食品以及食品对我们身体所起作用的了解远比以前先进多了。答案：选A。分析：句中and连接表示的是前后两个事物相加的概念，相当于复数，而those指代复数，that不能。
