3.We need some more facts and figures          we make the final decision.( 。
A.sinceB.beforeC.afterD.until

分析 我們需要更多的事實(shí)和數(shù)據(jù)才能做出最后的決定.

解答 答案B.since"自從";before"在…前";after"在…后";until"直到".這四個詞均可以用來引導(dǎo)時間狀語從句.從動作發(fā)生的時間順序來看,動詞need應(yīng)該發(fā)生在動詞make之前,可知答案選B.

點(diǎn)評 本題考查從屬連詞的用法.連詞的用法辨析,要注意分析主從句之間的邏輯關(guān)系,再確定相應(yīng)的連詞,同時注意不同的連詞的語義及用法區(qū)別.before作連詞時,意思是"在…前",強(qiáng)調(diào)時間.before的含義比較靈活,實(shí)際翻譯時應(yīng)結(jié)合具體情況靈活翻譯.before可以結(jié)合語境翻譯成"才…,就…",這時主句往往帶有時間狀語或直接表示時間概念,句子側(cè)重在從句;原文從句多后置,其譯文也后置.如:They had been married many years before a child was born to them.他們結(jié)婚許多年,才生了一個孩子.      But my teacher had been with me several weeks before I understood that everything has a name.可是,老師和我在一起好幾周之后,我才明白每一樣?xùn)|西都有名稱. It was some time before his eyes could bear the light after having been so long in total darkness.適應(yīng)了一陣子之后,他的眼睛才能夠忍受了那光線,因?yàn)樗谕耆暮诎抵写袅撕瞄L時間.

Hearing that you're wondering whether you should invite a tutor to help you prepare for the coming final examination,I'm shocked and I'll give you an exact'No'.
A tutor costs high,usually 150 yuan or more per hour,which you may not be able to afford.Besides,having studied that detailed information of tutor classes from my classmates,I find that most of the information is similar to that of school's,which is even with little or no extended materials,so it's absolutely no use if you listen to the teachers with full attention in the school and review what is on your notebook carefully after class.What's more,a tutor may make you depend fully onhim and lose your self-motivation on study,which is exactly the truth of study.Without it,you may never learn better.And that's why I say there's no need for you to invite a home tutor.
When it comes to preparing for the exam,I'd like to give you two suggestions.First,review the points which you're poor at.You will achieve twice the result with half the effort if reviewing the notes accompanied with several particular exercises.Second,check all the notes and make sure that you've captured all the details.
Try hard and I believe you can achieve a good score in the exam..
