求翻译：2.The second I need to strengthen is discrimination ,different word has different means.we must better understand meanings, correctly use vocabulary.For example “走”，It has more than four kinds of words in English: Walk”, “Stride”, “Stroll”, “Plod” They tell different meaning, expressing the different forms of "walk",and can’t be used interchangeable.another example :“点燃”has four words:“kindle， fire， ignite，light”. Among them, "kindle" emphasize burning slow and difficult;”fire” emphasize erupting; “Ignite” limited to use in some way warming the object until rapid or violent combustion; "Light" emphasize the results, such as light, heat or fireworks, etc.It is one of the difficulties to distinguish the words when we are learning we should pay great attention to those words.是什么意思？
