要點分析和參考譯文
要點：這是一個由and 連線的並列複合句。And前面的句子是強調句，強調的成分是僅位先行代詞，沒有意義。Mostly 用作副詞，意為多半。 For fear（that）= in order thatshould not happen意為生怕，以免。例如：I darent tell you what he did , for fear that he should be angry with me.（我不敢將他的.事告訴你，怕他因此對我發脾氣）。To leave her by herself相當於to leave her alone.
參考譯文：大部分時間都是他在講話。他似乎害怕停下來，生怕話一停，她就會請他離開。
要點：本句由whereas 連線在一起的兩個分句並列而成。the latter requiring an examinee to arrange a set of pictures into a sequence so that they tell a comprehensible story.是現在分詞獨立主格結構；the latter是現在分詞 requiring的邏輯主語：the latter指的是 an example of a performance subtest . so that they tell a comprehensible story 是so that 引導的目的狀語從句；其中主語they指的是：a set of pictures
