   规则动词和不规则动词的第三人称单数形式(加s或es)可以从原形推知。第三人称单数形式有三种读法:


  /iz/,/z/和/s/这三种读法分别在下列情况中出现:
  1、在以清、浊咝声结尾旳原形后面读作/iz/;例如:
  表 3.5a
  pass – passes /-siz/
  buzz – buzzes /-ziz/
  上面各例的-s形式总是以-es结尾的e
  2、除咝声外,在以浊音(包括元音)结尾的原形后面读作/z/;例如:
  表 3-5b
  call – calls /-lz/
  flee – flees /-i:z/
  rob – robs /-bz/
  try – tries /-aiz/
  3、除咝声外,在以清音结尾的原形后面读作/s/,例如:
  cut – cuts /-ts/
  hop 1hops 2 /-ps/
  knock – knocks /-ks/
  加-es (go/goes)和把-y变i再加es(try/tries)等的拼写规则与规则的名词复数形式的规则相同。

n.单脚跳,跳跃;vi.单脚跳,跳跃;着手做某事;vt.跳跃,跃过
  • The children had a competition to see who could hop the fastest.孩子们举行比赛,看谁单足跳跃最快。
  • How long can you hop on your right foot?你用右脚能跳多远?
跳上[下]( hop的第三人称单数 ); 单足蹦跳; 齐足(或双足)跳行; 摘葎草花
  • The sparrow crossed the lawn in a series of hops. 那麻雀一蹦一跳地穿过草坪。
  • It is brewed from malt and hops. 它用麦精和蛇麻草酿成。
