9.Not(never)…until…

　　For　one　thing,　we　can　never　wish　people　to　be　good　to　us　until　we　become　thoughtful　and　considerate.

　　We　can　never　wish　to　realize　our　dream　of　a　cleaner　and　more　beautiful　environment　until　all　of　us　take　actions　to　build,　protect　and　take　care　of　it.　

　　How　can　anybody　expect　to　lead　a　meaningful　life　until　he　is　far　from　any　kind　of　cheating　behaviors?　

　 　Other　people　view　repeated　failures　as　most　natural　on　the　way　towards　achievement　–　they　will　keep　on　trying　until　they　succeed　in　the　end.

　　Until　quite　recently　most　people　hold　a　hostile　attitude　towards　taking　a　rest　at　noon.

　　12.雙重否定

　　You　can　never　be　too　good　to　your　mother.

　　Last　but　by　no　means　the　least,　students　can　never　fail　to　find　peers　with　the　same　interest,　which　enable　them　to　explore　a　special　field　together.

　　Similarly,　you　can　never　write　a　good　research　paper　unless　you　concentrate　on　what　you　are　doing　and　have　a　right　attitude　towards　failure.

　　For　one　thing,　we　can　never　wish　people　to　be　good　to　us　until　we　become　thoughtful　and　considerate.
