说明： 有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语,例： He fell ill yesterday. 他昨天病了.（fell是系动词,后跟补足语,说明主语情况.）

实义动词的用法
实义动词词义完整,能独立作谓语,可分成：及物动词（transitive verb）和不及物动词（intransitive verb）.
1．及物动词要求有宾语

②He asked the teacher a few questions．他向老师问了几个问题.
③We have friends all over the world.我们的朋友遍天下.
④Children and young people like bright colors．孩子和年轻人喜欢亮丽的颜色.
2．不及物动词不要求宾语

②George's father lives there．乔治的爸爸住在那里.
③Let's go home．我们回家吧.
④The examination ended at 11:30 A．m．考试上午十一点半结束.
3．特殊实义动词
英语动词很多既是及物动词又是不及物动词,如 close, begin, study, leave, work等.
①The post office closes at 9:00 p. m．邮局晚上9点关门.
②Close the window, please．请关窗.

3）feel作感觉到,摸上去（系动词）+形容词
It feels nice to be home again.
She felt tired after the long hike.
作行为动词时+副词He felt his way hopelessly around the dark room.
4）make sure 意为“确保；确信；查明”,后面常接宾语从句及由 of 引起的短语. Make sure （that） he comes at once.一定叫他马上来. You’d better make sure of time.你最好查明时间. Make sure of it before you start out.出发前查明这件事.
be sure 意为“肯定；确定”, be sure 后可跟不定式或“疑问词+不定式”,构成 be sure to do, be not sure whether to do 结构,要注意“疑问词+不定式”一般用在否定句中.be sure 后还可跟从句,肯定句后跟 that 从句,否定句后跟 if /whether 从句. He is sure to come.他肯定会来.

5）real和true的区别：
real强调人或事物真实的存在,而不是想像的或虚构的.
true 则强调符合事实,是真的,而不是假的,是相符的,而不是编造的. 【例】 Father Christmas isn't real．圣诞老人不是真有其人. I'm learning to skate on real ice．我在真正的冰上学溜冰. Read through the passage first and then tell me which answer is true.先通读一遍这篇文章,然后告诉我哪个答案是正确的. A true friend is a real friend．忠诚／忠实的朋友是真正的朋友.
