The grammatical words which play so large a part in English grammar are for the most part sharply and obviously different from the lexical words. A rough and ready difference which may seem the most obvious is that grammatical __1__ words have “less meaning”, but in fact some grammarians have called them __2__ “empty” words as opposed in the “full” words of vocabulary. But this is a rather __3__ misled way of expressing the distinction. Although a word like the is not the name __4__ of something as man is, it is very far away from being meaningless. there is a __5__ sharp difference in meaning between “man is vile” and “the man is vile”, yet the is the single vehicle of this difference in meaning. Moreover, grammatical words __6__ differ considerably among themselves as the amount of meaning they have even in __7__ the lexical sense. Another name for the grammatical words has been “little words.” But size is by no mean a good criterion for distinguishing the grammatical words.” __8__ of English, when we consider that we have lexical words as go, man, say, car. __9__ Apart from this, however, there is a good deal of truth in what some people say: we certainly do create a great number of obscurity when we omit them. This is __10__ illustrated not only in the poetry of Robert Browning but in the prose of telegrams and newspaper headlines. 参考答案及解析: 1 删掉the 此处的most并不表示obvious的最高级，而是用作副词修饰obvious，表示程度很高，因此前面不能加the。 2 将but改为and 根据文章的意思，这里要用并列关系的and。 3 将in改为to as apposed to 是固定搭配，意思是“与……相比”。 4 将misled改为misleading 5删掉away 此处考查固定用法。 far from being...意思为“远非”“远远不怎么样”，符合这里的意思。而far away from 表示离某处很远。 6 将single改为only或者sole 这里要表达“唯一的”。 7 在as后面加to或者将as 改为in 联系上下文，此处的意思是“grammatical words 本身在某某方面也有相当的差异，”as to 有“关于”或者“在某某方面的意思”；将as改为in，用differ from something in…也可表达这个意思。 8 将mean改为means 9 将as改为like，或者在as前面加such 10 将number改为deal或者amount obscurity是不可数名词，不能用a number of 来修饰
