　　A body at rest will remain at rest and a body in motion remain in motion at a constant speed in a straight line, unless acted upon by an external force.

　　要點分析和參考譯文

　　要點：這是一個由and 連接的并列復(fù)合句。And前面的句子是強調(diào)句，強調(diào)的成分是he.It僅位先行代詞，沒有意義。Mostly 用作副詞，意為“多半”。 For fear（that）= in order that……should not happen意為“生怕……，以免……”。例如：I daren't 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(fā)脾氣）。To leave her by herself相當(dāng)于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 連接在一起的兩個分句并列而成�！皌he latter requiring an examinee to arrange a set of pictures into a sequence so that they tell a comprehensible story.”是現(xiàn)在分詞獨立主格結(jié)構(gòu)；“the latter”是現(xiàn)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(dǎo)的目的狀語從句；其中主語“they”指的是：“a set of pictures”
　　參考譯文：口頭語言測試的一個實例是測驗詞匯能力，而行為表現(xiàn)測試的實例是測驗排列圖畫能力。后者要求受測試者把一組圖畫排序，這個次序應(yīng)該能夠表達一個可以理解的故事。

　　要點：這是一個并列復(fù)合句。And 連接兩個句子，構(gòu)成并列句。Unless 是連詞，連接下一個子句，做前面兩個主句的狀語從句。Unless 后面省略了it is.At rest和in motion 是兩個介詞短語，分別作body的定語，意思為“處于靜止?fàn)顟B(tài)”和“處于運動狀態(tài)中”
　　參考譯文：除非受到外力作用，靜止的物體將繼續(xù)保持靜止，運動的物體將繼續(xù)作勻速直線運動
