英語六級攻克閱讀關(guān)鍵句205. To defend their profits, the drug compani

205. To defend their profits, the drug companies have warned Canadian wholesalers and pharmacies (藥房) not to sell to Americans by mail, and are cutting back supplies to those who dare.

譯文　為了維護(hù)自身的利益，藥品公司已經(jīng)警告加拿大的批發(fā)商和藥房，不要以郵寄的方式向美國人賣藥，并且正在削減敢這樣做的批發(fā)商和藥房的藥品供應(yīng)。

點睛　本句的主干是...the drug companies have warned Canadian wholesalers and pharmacies...and are cutting back supplies...。其中，who引導(dǎo)定語從句，修飾those；have warned和are cutting back是謂語。

defend意為“維護(hù)”。如：

The union said that they would take action to defend their members' jobs. 工會說，他們將采取行動維護(hù)會員的工作權(quán)益。

wholesaler意為“批發(fā)商”。pharmacy意為“藥房”。cut back意為“削減”。

考點歸納　dare意為“敢”，通常用作dare to do sth.（敢于做某事）。如：

Most people hate Harry but they don't dare to say so in Harry's face. 大多數(shù)人都恨哈里，但是他們不敢當(dāng)著哈里的面說出來。

此外，dare還有三個常用的口語表達(dá)：

don't you dare do sth.，表示說話人很憤怒，并且警告某人不要做某事。如：

Allen, don't you dare go anywhere else, you hear me? 艾倫，你不能去其他任何地方，聽見了嗎？

how dare you do sth.，表示說話人很惱火地質(zhì)問某人“你怎么敢做某事”。如：

How dare you pick up the phone and listen in to my conversation! 你竟然敢用分機(jī)偷聽我打電話！

dare I say it，表示說話人明知自己即將說的話會讓聽者失望或者憤怒。如：

Politicians usually attracts young women, dare I say it, because of the status they have in society. 我斗膽說一句，政客對年輕女性有吸引力，這是因為他們的社會地位高。
