對我們提出的有關看電視的問題的答案也挺有意思。1）句子主語為theanswers，故謂語用were。2）表示“…的答案”要用“answerto…”如：There’snoeasyanswertothisproblem.這個問題沒有簡單的答案。Heranswertoyourquestionisabig“NO”!她對你所提的問題的答案是一個大大的“不”字！第二十一頁，編輯于星期五：十點三十分。3）表示“有關…的（問題）”用questionabout…如：Heaskedussomequestionsaboutourdailyhabits.他問了一些有關我們?nèi)粘Ａ晳T的問題。Herquestionsaboutyouwerenotsofriendly.她有關你的那些問題并不那么友善。第二十二頁，編輯于星期五：十點三十分。4.Althoughmanystudentsliketowatchsports,gameshowsarethemostpopular.雖然很多學生喜歡看體育節(jié)目，但游戲類節(jié)目是最受歡迎的。although為連詞，意為：“雖然，盡管”。注意：在英語中，當表示“雖然…，但是….”這樣的意思時，although和but不能在同一個句子中使用。也就是說，在一個句子中，有although就沒有but，反之亦然。如：Althoughthecarisold,itstillrunswell.=Thecarisold,butitstillrunswell.這輛小車舊了，但是依然跑得不錯。第二十三頁，編輯于星期五：十點三十分。5.Sostartexercisingbeforeit’stoolate!所以趕緊鍛煉起來，不要等到來不及了。It’stoolate字面意思為“為時太晚，來不及了”是英語的一個常用表達。如：Nowyouknowyouarewrong,butit’stoolate.你現(xiàn)在知道錯了，已經(jīng)太晚了。句中，It’stoolate與before共同組成從句，表示“不要等到為時已晚；不要等到來不及的時候；趁還來的及”。如：Youshouldworkharderbeforeit’stoolatetocatchup.你現(xiàn)在用功還趕得上。第二十四頁，編輯于星期五：十點三十分。6.Butmy
