自考英语一笔记(75)
8. We have been trying to pin down by experiments what people mean by these expressions in specific contexts，…pin作名词用时指“别针，大头针”，如a safety pin （安全别针）；作动词用时指“别住”；“使不能行动”，pin down的意思是“准确说明”，“牵制”。如：
1） He pinned a badge on his jacket. （他在外套上别了一枚徽章。）
2） She pinned the papers together before giving them to the manager. （把文件给经理前，她用针把它们别好。）
3） They pinned him down to a promise. （他们迫使他履行诺言。）
4） We are trying to pin down his speech. （我们正努力准确说明他的讲话。）
两个by在句中都是介词，表示“靠，用，通过”，如：
1） What do you mean by that？ （你这样讲是什么意思？）
2） He put the young man in an awkward situation by asking him some personal questions.
（他通过问一些私人性问题使那个年轻人陷入尴尬。）
9. …we find that the number depends of course on the items involved.
…the size of the population of items influences the value assigned to an expression.
上面两句中的过去分词involved和assigned其前都省去了that （which） are （is），做定语修饰items和value.
