四分之三 three fourths/quarters ；

4. take measures to do sth 采取措施做某事
eg: It is necessary for you to take measures to

5. work well in sth/doing sth “在某方面起明显的
作用”
eg: Doing eye exercises works well in protecting our eyesight.做眼保健操在保护我们的视力方面起到了明显的作用。
6. thanks to sb/sth 幸亏，由于= because of …/with the help of…
eg: Thanks to the heavy rain, our crops are saved.
多亏了这场大雨，我们的庄稼得救了。
thanks for sth/doing sth （为某事） 感谢、道谢
many thanks !
7. offer sb sth 提供某人某物
offer sth to sb 把某物提供给某人
eg: They decided to offer Joe the job.
