　　[单元语言点综合练习]

　　Ⅰ.单项填空

　　1．(陕西高考)My uncle hasn't been able to quit smoking, but at least he has ________.

　　A．cut out　　　　　　　 　B．cut down

　　C．cut up D．cut off

　　解析：选B　句意：我叔叔虽然没能戒烟，但是至少他已经吸得少了。cut out"裁剪，戒掉"；cut down"消减，压缩，缩减"；cut up"切碎，切开"；cut off"切断，隔断，断绝"。由语境My uncle hasn't been able to quit smoking可知说话者的叔叔并没有"戒掉"吸烟，从后面的but at least的转折可以得知"他减少了吸烟的量"。因此该题的正确答案为B项。

　　2．A(n) ________ idea or way of thinking is based on general ideas rather than on real things and events.

　　A．concrete B．absolute

　　C．abstract D．absent

　　解析：选C　句意：抽象的想法或者思维方式是依据总体思路而不是真实的事情或者事件。concrete意为"具体的"；absolute意为"绝对的，完全的"；abstract意为"抽象的"；absent意为"缺席的"。根据语境可知C项正确。

　　3．Working hard is not the only ________ of great success, but it is among the essential requirements.

　　A．sign B．signal

　　C．guarantee D．support

　　解析：选C　句意：努力工作不是取得巨大成功的唯一保证，但它是基本的必备条件之一。guarantee在这里是名词，意为"保证"，符合题意。sign"标志，符号"；signal"信号"；support"支持"。

　　4．-Jenny was ________ to hospital with a soaring temperature this morning.

　　-Really? I'll go to see her this evening.

　　A．admitted B．submitted

C．distributed D．sentenced
