　　much to one's regret 深感遗憾

　　with regret 遗憾地

　　remember /forget/ regret后既接doing又接to do作宾语，它们选择的依据就是看非谓语动词与谓语动词发生的先后确定。当非谓语动词的动作先于谓语动词发生时，就用v.­ing或having done形式；后于谓语动词发生时，就用to do sth.

　　I only regret not struggling for the entrance exams at first. (强调“没努力”发生在regret之前)

　　I regret to inform you that we are unable to offer you employment. (强调“通知你”发生在regret之后)

　　4、thanks to

　　根据语境猜词义

　　(1) Thanks_to the English language，we can learn a lot from other countries.

　　(2) It was thanks_to your timely help that we accomplished the task on time.

　　(1)B　(2) A

　　because of/due to/owing to/on account of

　　because of 只能引导状语。

　　We must not get discouraged because of such a minor setback.

　　due to 英国英语中只能引导表语，美国英语中既可作表语也可作状语。

　　Our victory was due to the assistance of the star­player.

　　owing to既可作状语又可作表语，以状语最常见，它所引导的状语必须是修饰全句的，故必须用逗号与主句隔开，这与because of是不同的。

　　They decided to postpone the trip, owing to the change of weather.

　　They refused to give up the project merely because of the lack of skilled personnel.

　　在第一句中owing to 直接影响了主要动词decide，而在第二句中because of 却只影响了次要动词give up, 而对主要动词refuse无任何影响。且第一句中，owing to可放在句首，而第二句中because of则不能。

　　thanks to也是引导状语，除表示“由于”之外往往带有感谢或讽刺的意思。

　　Thanks to your help, much trouble was saved.

　　单项填空

　　()______ the new policy, we are now having a happy life.

　　A. Thanks to

　　B. Because

　　C. For

　　D. Thanks for

　　4、thanks to

　　A　考查近义词的辨析。此处，thanks to应为“多亏了”， because后应加句子； for 表示补充说明的原因，后接分句，一般不在句首。

　　试填下空：

　　(1) ______ your help.We all passed the exam.

　　(2) ______ your help, we all passed the exam.

　　A. Thanks for

　　B. Thanks to

　　(1) A　由于有句号，说明它们彼此独立，互不为因果关系，所以答案是A，表示“因……而感谢”。

　　(2) B　因为/由于你的帮助，我们才通过考试。里面有因果关系。thanks to your help为原因状语短语，所以后面用逗号。

　　5、lead to

　　根据语境猜词义

　　(1) All roads lead_to Rome.

　　(2) His carelessness led_to his failure.

　　根据语义找匹配：A. 导致；造成(后果)　B. 通向
