分子用基数词，分母用序数词，分子大于1．分母要用复数。如： 1\\3 0ne third或a third
1\\2 0ne\\ahalf 分数与名词搭配时，之间常用介词of.即“分数+of+名词”这一结构一作主语时，谓语动词的单复数视其后面的名词而定，如果名词是复数．谓语动词用复数形式．名词是单数或不可数名词时，则谓语动词用单数。如： one third ofthe watcr is dirtv．1/3酌水是脏水。

=How large is the population of the city?这个城市有多少人口？
2. Maybe you fear that you won’t be able to find anything eat in a foreign country. fear的用法如下：
(l)fear剧，害怕，担心，相当于口语中的be afraid,后面常接从句或不定式，如： -Is the cat going to die?这只猫要死了吗？-I fear so.恐怕如此． I fear that we may be too late.很遗憾，我们可能太迟了。 He feared to tell her the truth.他害怕告诉她真相。

单元语法归纳 现在完成时的用法
▲概念引入
在Unit6中，我们学过have/has been doing这种结构，里面就涉及现在完成时，因为现在完成时基奉结构为助动词：have/has+动词过去分词，请看：
I have been sitting-here for half an hour．我在这儿坐了半个小时。 He has already posted the photos.他已经把照片寄出去了。 ▲问题呈现
1．现在完成时有哪些用法？
2．现在完成时与一般过去时有何区别？ ▲解疑释惑
现在完成时的用法包含两层：
1．完成用法。表示过去发生的或已完成的动作对现在造成的影响或结果，特点是动作不延续，常与一些不确定的时间状语（如already，yet，before，recently）或频度副词(如ever，never，once，just)连用。如：She has already finished her homewo-k.她已经做完了家庭作业。 I have ncver seen an elephant bcfore．我以前从未见过大象。
2．持续用法。表示过去已经开始，持续到现在的动作或状态，特点是动作的持续性，常与表示一段时间的时间状语（如for、smce短语）连用。
He has lived hcre since he was ten自从O岁时就一直住在这儿。 She has becn in the I)cague for 3 vears.他入团已经3年了。 尽量一股过去时与现在完成时的动作发生在过去．但有本质区别：一般过去时只是描述过去的事情或状态，常与表示过去的具体时间状语连用；而现在完成时强调过去的动作对现在造成的影响或结果，说的是现在的情况，不能与表示过去的时间状语连用。 试比较：
He turned off the light．（灯是过去关的，现在的情况不清楚）．他把灯关了。 He has turned off the light.（灯是过去关的，但现在不亮）他已经把灯关了。 即学即用
