11.D解析：prevent sb from doing sth阻止某人做某事,所以用being；.being what he can be成为他想成为的人
　　12.C解析：这是个同位语从句,即that后面的内容就是principle,判断同位语从句,只需把that换成is即可,例如本句the principle_is__to love is to give,not to take.句意完整.
　　13.B解析：on表示一.就.后面的动词用doing形式
　　14,A解析：nor是否定词,所以要部分倒装,即A选项,翻译为能量不凭空产生,也不能被摧毁.
（讲的是能量守恒定律）
　　15.D.解析：Even if cut off
虽然与欧洲大陆是分隔开的,但英格兰却一直与外界保持着密切联系
　　16.C解析：这是固定的句型：It is (high) time sb.did sth.该是某人做某事的时候了
　　17.D解析except表示“除去,不包括”,强调所排除的“不包括在内”,一般表示同类之间的关系,常同nothing,all,none,nobody,any等不定代词以及every连用.except 经常接名词或代词,但也可接副词,介词短语,例如：
he office is open every day except Sundays.
除了星期日这家公司每天都营业.
　　Except后排除的内容与主语往往是同一类的,而except for后所排除的内容与主语往往不是同一类的.指从整体中除去一个细节,一个方面；例如：
Your writing is good except for a few grammar mistakes.
除了几处语法错误外,你的作文写得很好.
　　.in addition通常后面跟介词to表示除了.之外
　　besides除.之外,还.
　　18,.D解析因为是特指,并且be动词为is说明是同一个人,所以选D
　　19.D解析：put off.till推迟到
　　20.C解析：因为a所以后面接名词.A是动词,变化；B是形容词,后面直接跟名词；D也是名词,美德,贞操,功效的意思,与句意不符.
