她說它對我的健康有益。1)此句為賓語從句,says后面跟的從句的時態(tài)必須和主句中謂語動詞時態(tài)保持一致,都用一般現(xiàn)在時。2)begoodfor對……有好處Languagepoints例如：

Vegetablesaregoodforourhealth.

蔬菜對我們的健康有益。

Junkfood

are

notgoodforourhealth.

垃圾食品對我們的健康有害。2.onlyonetothreetimesaweek

每周只有一到三次注意這種表達,“to”為介詞。翻譯：1)兩到三次。

twotothreetimes.2)每月四到五次。

fourtofivetimesamonth.3.Theanswerstoourquestionsaboutwatchingtelevisionwerealsointeresting.

對我們提出的有關(guān)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！3）表示“有關(guān)…的（問題）”用questionabout…如：Heaskedussomequestionsaboutourdailyhabits.他問了一些有關(guān)我們?nèi)粘Ａ?xí)慣的問題。Herquestionsaboutyouwerenotsofriendly.她有關(guān)你的那些問題并不那么友善。4.Althoughmanystudentsliketowatchsports,gameshowsarethemostpopular.雖然很多學(xué)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(dāng)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。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。3aLookattheinformationinthechartandcompletethereport.ActivitiesDaysayearExercise365Readbooks365WatchTVforover2hours320 Drinkjuice210Eathamburgers95helpwithhousework20Stayuplate15Gotothedentist0Janeisa16-year-oldhighschoolstudentintheUnitedStates.AmericanTeenagermagazineaskedheraboutherhabits.Janehasalotofgoodhabits.She
