二、同、近义词辨析
1．likely, possible 与probable
（1）三者均表可能性，但意思有别。possible指客观上有可能性，但往往含有希望很小的意味；probable比possible可能性稍大，有“较为可能、大概”，指有实际依据；likely是从外表迹象判断有可能发生的事。 eg：
It’s possible, though not probable, that he will come tomorrow.
他明天可能来，但也不一定准来。
She is likely to ring me tonight. 今晚她很可能给我来电话。
（2）possible 不能用人作主语。possible 常用于下列句型：
It is possible to do sth. It is possible for sb. to do sth.
It is possible that … eg:
Is it possible to say so?可能这样说吗？
It is possible for me to do it. 我可能做那件事。
（3）probable 也不能用人作主语。一般只用于下面句型中：
It is probable that … eg:
It is probable that he will come. 他很可能要来。
（4）likely 既可用人作主语，也可用物作主语。通可用于“It is likely that …”句型中。 eg:
He is likely to come. = It is likely that he will come.
他可能要来。但不能说：It is likely for him to come.
（5）impossible, improbable, unlikely 用法与上述类似。
2．catch, grasp, seize 与snatch
catch是普通用语，用“设法抓住，捉住”的意思； grasp表示牢牢地“抓住”；seize指“突然用力抓住使不逃脱”；snatch 表示迅速的拉扯动作、出其不意地“抓取”。 eg:
The police caught the thief as he ran. 小偷逃跑时被警察抓住了。
He grasped his gun and rushed out. 他抓起枪就冲了出去。
He seized the gun from the enemy soldier. 他从敌人士兵手中夺过了枪。
The thief snatched her handbag and ran off. 小偷抢走了她的手提包就跑了。
