   五个基本句型


  根据动词的特性,构成英语中五个基本句型:
  1) 主语 + 系动词 + 表语
  2) 主语 + 不及物动词 (+ 其他成分)
  3) 主语 + 及物动词 + 宾语
  4) 主语 + 及物动词 + 双宾语
  5) 主语 + 及物动词 + 宾语 + 宾语补足语
  我们在学习5个基本句型时,主要关心每个句型中的出题点在哪里。
  (一)第一句型: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 1 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 2 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 3 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)

adv.完全地,彻底地,十足地
  • The soil must be thoroughly turned over before planting.一定要先把土地深翻一遍再下种。
  • The soldiers have been thoroughly instructed in the care of their weapons.士兵们都系统地接受过保护武器的训练。
n.天花
  • In 1742 he suffered a fatal attack of smallpox.1742年,他染上了致命的天花。
  • Were you vaccinated against smallpox as a child?你小时候打过天花疫苗吗?
adj.充分的,富裕的,宽敞的,宽大的
  • Let's produce ample food and clothing with our own hands.自己动手,丰衣足食。
  • The supply is ample and prices are stable.供应充沛,物价稳定。
