7. 注意as expected（不出所料）和than expected（比预料的更）这个搭配。如：
He returned three days earlier than expected. 他回来的时间比预料的要早3天。
The ascent of the mountain is proceeding as expected. 登山正在按计划进行。
8. be (only) to be expected是一个很有用的表达，其意为“在预料当中的”“可能发生的”“相当正常的”。如：
His weakness after the illness is only to be expected. 他病后体弱是预料之中的事。
It is only to be expected your son will leave home eventually. 儿子总归要离开家的，这种事很难免。
