3、hear与listen to：hear侧重点是听到，听见什么，而listen to是侧重于听的倾向，但hear用于无意中的听见，而listen to却用于集中注意力的听。

2、rise和raise：rise是不及物动词，其过去式是rose，过去分词是risen，而raise是及物动词，是规则动词。

动词是是各类考试的重点，高考试题中，单项填空、完形填空和改错等三项题型中，动词辨义的比重较大，并逐年增加。动词辨义主要指：1、形状相同的动词之间辨义。如：lie, lay; hanged, hung; rise, raise; sit, seat等。2、意义相近的动词之间辨义。如：borrow, lend; speak, say, talk; hope, wish等。3、动词与其它词形相近、意义相似的词的辨义。如：advise, advice; cost, worth; pass, past 等。4、意义不同，但容易混淆的动词的辨义。如：explain, say; discover, invent, uncover; find, find out等。5、某些常用动词的习惯用法的辨义。如：ask, give, call, make, find, get, keep, want, see, hear等。6、某些常用动词短语的辨义。如：give in, give up, turn on, turn off, turn down, turn up等。
