例1：
He is going to take on a new job next week. (2015年6月六级)
他在下周要接受一份新的工作。
结构分析：He是主语，is going to take on是谓语，a new job是宾语，next week是时间状语。
例2：
I am glad to tell you that we are going to take you on.
很高兴通知您，我们打算雇佣您了。
结构分析：I是主语，am glad是谓语（系动词am+表语glad，构成系表型谓语）， to tell you that we are going to take you on是不定式词组作宾语（to+谓语tell+间接宾语you+that引导的直接宾语从句，we是主语，are going to take是谓语，you是宾语，on是宾语补语）。
