　　[附注] 关于等差句有以下几点需要注意：

　　1)    句型16 "not to speak of" 等词组也可用以表示差比, 如: Even a worm, when trodden on, will turn, not to speak of a man outraged.

　　2)    former, latter, elder等形容词, 词尾虽然是比较级形式, 但它们永远不用于比较句中, 也不能跟than, 如： He will come here in the latter part of year.

　　3)    等差既可以指出相差的数目, (用by+数词表示) 也可以指出相差的范围, 如: of +名词, with regard to, in point of, with respect to, with reference to, with relation to, in the sphere of, in the field of等等。例句:  She is the more patient of the two.   In point of commerce, Shanghai is more prosperous than Nanjing.   With reference to territory, China is larger than America.

　　4)    有些语句的词序变动较大阅读和翻译时要弄清其结构。如：Easier said than done. (=It is easier to be said than to be done.)  In science, more than in any other human institution, it is necessary to search out the past in order to understand the present and to control the future. (= It is more necessary in science than in any other human institution to search out…)

　　有时一个词的原级和比较级在一同结构的句中会产生不同的意义，如：If he was ten years old, he would understand it. ≠ If he was ten years older, he would understand it.

　　5)    要注意避免不合理的比较。如：（误）The face of his father looks older than his uncle.

　　（正） The face of his father looks older than that of his uncle.  His father's face looks older than his uncle's.
