appreciate
1.appreciate后面接以that引导的从句主要是美国用法。例如：I appreciate that the plan has worked well. 在英国通常在that 前面加上the fact。
2.appreciate后面接动名词，不接不定式，如可以说He appreciates being advised，不可说He appreciates to be advised。
3.I shall appreciate it if you will give me his address里的it最好不要省去。
4.It is appreciated that...和It will be appreciated that...都是公文里的惯用语，有人以为可以省去，如It is appreciated that you have accomplished the task可以改作You have accomplished the task。
