主语 + 系动词 + 表语

  1) 系动词一般为be 动词。

  注意:look, feel, sound, smell, taste, get, become, come, go, turn, grow, keep, seem, stand等词可以作“半系动词”用,按行为动词方式变化,起系动词的作用。

  试验比较:

  —— He felt the pockets thoroughly but did not find a single penny.(他摸遍了口袋但没有找到一分钱。—— feel为行为动词)

  —— You look pale. Do you feel unwell? (你脸色苍白,感到不舒服?—— look / feel为系动词)

  一般来说,动词后面跟的是个形容词或名词,该动词为系动词, 如:The plan sounds perfect. / The flower smells nice. / The dish tastes delicious. / It is getting dark.

  实例:

  “Don't worry. Let me take your pulse first.” “Oh, it ______ normal.” (脉搏正常)

  A. is felt

  B. is feeling

  C. feels

  D. felt

  解题思路:normal为形容词,前面应为系动词;系动词没有被动语态,故A不对; look, feel, sound, taste, smell, seem等半系动词一般不用进行时,B也不对;D时态错了,故正确答案为C.

  2)there be是英语中非常重要的一个句型: there是引导词,不解释 "那里"; 这是个倒装句, 主语在be动词的后面, be动词的单复数由后面的主语决定。

  注意中国学生容易搞错的问题:

  There isn't enough furniture in the room.(房间里家具不够)

  错:There hasn't enough furniture in the room.

  There is no doubt that smallpox has been wiped out in China.(毫无疑问,中国已消灭天花。)

  错:It is no doubt that smallpox has been wiped out in China.

  There is ample evidence that AIDS is spreading quickly in Asia. (充分证据表明,爱滋病正在亚洲迅速蔓延。—— 同位语从句)

  错:It is evidence that AIDS is spreading quickly in Asia. (可以: It is evident that AIDS is spreading quickly in Asia. - 主语从句)
