答案:
T:请看第1题。在4个选项中,哪一个是“德国人”的复数形式?
S:选项C。
T:错了。与“美国人”的复数形式相同,都要加-s,因而正确选项是B。请看第2题,advice(建议)是可数名词吗?
S:不是。因此,要用a piece of advice或much advice等,选C。
T:请看第3题information也是一个不可数名词,因而要用选项B(plenty of)。
S:plenty of可用来修饰可数名词吗?
T:plenty of的用法与a lot of相似,既可修饰不可数名词又可修饰可数名词。接着看第4题。名词修饰名词时,用作修饰语的名词一般用单数形式,如book store。
S:这样说来,本题该用选项C。
T:是的。请看第5题。裤子trousers只有复数形式。
S:那2条裤子怎么说?
T:要说two pairs of trousers。再看第6题。句中fat一词意为“脂肪”,是不可数名词。
S:那就不能用number,应该选C。a large amount of(大量)修饰不可数名词。
T:好,接着看第7题。sheep(羊)是个可数名词,并要注意sheep单复数同形。
S:那就不能选A,因为a great deal of与a large amount of一样,是用来修饰不可数名词的。选项C(a good many)是什么意思?
T:a good many意为“许许多多”,用以修饰可数名词,因而本题要用选项C。请看第8题:他的妻子和女儿的生日都在3月份。
S:指“两个人的各自生日”,那该用选项D。
T:完全正确。请看第9题。“一个半小时的步行”怎么说?
S:one and a half hour’s walk,选B对吗?
T:错了。one and a half必须加上可数名词的复数形式,如表示所有格,就在s之后加上“’”。请看第10题。在4个选项中,哪个选项表示“许多”的意思?
S:quite a few,选D。
T:是的,quite a few mistakes意为“许多错误”。

S:那该说something wrong,是吗?
T:是的。请看第2题。句中taste用作系动词,意为“尝起来”,要接形容词。因而本题要用选项A。
S:为何不能用
T:well用作形容词,只能表示“身体好”的意思。接着看第3题。
S:too和either都可以放在句尾,表示“也”的意思,那该用哪一个?
T:肯定句用too,否定句用either。句中no theatre表示否定,因而本题要用选项C。再看第4题。本题涉及3个形容词修饰一个名词。一般说来,表示材料的词,如wooden(木头的),要最靠近被修饰语,而表示大小、新旧、形状、颜色的词,放在表示材料的词之前。
S:如按大小、新旧、形状、颜色的顺序,那该选D。
T:是的。请看第5题。double意为“翻一倍”。
S:more than doubled是否表示“翻一倍都不止”的意思?
T:正是。第5题要用选项C。接着看第6题。英语中,too much常用来修饰不可数名词,如too much water / money,而much too修饰形容词或副词。
S:这样说来,本题的正确选项是B,对吗?
T:对的。再看第7题。虽然deep和deeply都可用作副词,但不同的是,deeply表示抽象的意思,“深深地、非常”。work deep into the night意思是:工作到深夜。本题选C。
S:第8题主要涉及enough的前后位置。
T:正是。enough要放在形容词或副词的后面。根据句意,本题要用副词,因而选C。接着看第9题。
S:按大小、新旧、颜色、材料的顺序,本题要用选项B。
T:完全正确。接着看第10题。hard用作副词是“努力地,刻苦地”意思,而hardly则含有否定之意,意为“几乎不”。
S:根据句意:Alice每天刻苦地练习弹钢琴,但Helen,几乎不弹。本题该用选项B。

T:说得对。本题用选项B(four times as big as)。接着看第4题。注意比较对象要一致。
