v.(动词)

alter, become, change, convert, modify, turn, vary

其区别是：

1.change在这几个词中是最普遍、最不正式的一个,可用于任何变化的过程,而不论变化的性质和程度; alter指局部的、表面的、轻微的“改变”“改动”,修改后仍基本上保持原状; alter和convert都指形式和用途上的局部微小改变; turn指彻底改变,以至面目全非,且常用于朝坏的方向改变; modify指限定在一定范围内的修改或修饰,以使之更完美; vary则指事物或其一部分暂时地或反复地变化,从而使事物各部分呈现不同外貌和特点。例如:

When matter changes to a substance different from what it was, the change is a chemical change.当物质变成和原来不同的物质时,这种变化是化学变化。

change，alter，vary，convert，modify，transform，turn

这些动词均含有“变化，改变”之意。

change指任何变化，完全改变，强调与原先的情况有明显的不同。

alter常指轻微的改变，强调基本上保持原物、原状的情况下所进行的部分改变。

vary暗示不规则或断断续续地变。

convert指进行全部或局部改变以适应新的功能或用途。指信仰或态度时，强调较激烈、大的改变。

modify强调起限定作用的变化或变更。指细小的变化，常含“缓和、降调”的意味。

transform指人或物在形状、外观、形式、性质等方面发生的彻底变化，失去原状成为全新的东西。

turn指外形、颜色、气味、性质等方面的变化，比change更通俗。
