②thenewpolicy,wearenowhavingahappylife.（2010•01•安徽亳州检测）
A.ThankstoB.Because
C.ForD.Thanksfor
①解析：选C。because和as虽然也表示“因为，由于”，但后面需接句子，而句中是短语，故应用thanksto。句意为：幸亏你及时帮忙，我们才按时完成了任务。

（2010•01•江苏徐州检测）
A.nothavewatchedB.notwatch
C.hadn’twatchD.haven’twatch
①解析：选B。考查wouldratherdosth.这一结构的用法。而do,will和should都不能与rather搭配。wouldrather(not)dosth.意为“宁愿（不愿意）做某事”。
②解析：选A。wouldrathernothavedone意为“本不想做……（实际却做了）”。后一句句意为：否则我现在已经完成了我的文件。所以前句表示“本不想看球赛却看了”，故选A。

HeisthelastpersontoMary’sbirthdayparty.（原创）
A.toinviteB.tobeinvited
