中考英语考点：半连系动词替换法

　　替换法
　　分析以上10组句子我们不难看出B组斜体动词均为连系动词，因为如果我们把动词 be（是）的适当形式替代斜体动词，句子能够成立，后面的成分即是表语。
　　（1）He was a perfect fool．
　　（2）He was a traitor to his country.
　　（3）I was very hungry after a long walk．
　　（4）Our motherland is stronger and stronger．
　　（5）Some of the land was covered with water．
　　（6）The story is interesting．
　　（7）The flowers are sweet．
　　（8）Holding the note in his hand, he was there dumbfounded．
　　（9）They were mad．
　　（10）He was never satisfied with his success．
　　反之，如果把 be（是）动词的适当形式替代 A组斜体动词，句子则不能成立，无法解释，A组动词均不为连系动词：
　　*（l）Please be at the blackboard．
　　*（2）Be to Pagel6．
　　*（3）He was if his duty to help others．
　　*（4）Be me some ink．
　　*（5）Such words are not a scholar．
　　*（6）The black key on the piano won't be．
　　*（7）I am sure I am gas．
　　*（8）He was too weak to be．
　　*（9）He is to school early every morning．
　　*（10）I was 3 weeks in Paris．
　　另外半连系动词是由实意动词变来的。所以把含有半连系动词的句子改为疑问句时，一定要用助动词。
　　例如：1． Do they look tired？
　　2．Has she got ready？
　　3．Did it become much more expensive to travel abroad？
　　不论完全连系动词或半连系动词，它们都有时态的变化，但有些半连系动词从形式上看像是现在进行时，实际上并不表示动作正在进行。而是表示“渐渐”的意思或表示一种感情色彩。
　　（1）It's getting warmer and warmer．天渐渐暖和起来了。
　　（2）Are you feeling better now？你现在好点了吗？
　　因为半连系动词本属于不及物动词，所以没有被动语态。
　　如不能说：* Good medicine is tasted bitter to the mouth．应说：
　　Good medicine tastes bitter to the mouth．良药苦口。
　　半连系动词的教学还是个较困难的问题，但在初学阶段用先比较，再替换的方法，还是能使学生掌握哪些实意动词可充当半连系动词，收到事半功倍的效果。
