八年级英语下册第一单元知识点讲解(新目标英语)

Unit 1 Will people have robots
 
一、alone adj. &adv. 与  lonely
 
1. =by oneself  独自的/地;孤独的/地; 独立的/地
   eg, He likes living alone.
       I mended the bike alone.
2. and no other 只有。唯有 (跟在名词或代词后面)
   eg, Mr Smith alone  knows what happened.
   You alone can help me in the work.
注意:alone 强调客观上“独自,单独一人”。
lonely adv.
1. 作表语。其意思为  “孤单”
 eg, He feels lonely. (作表语)
2. 作定语,修饰表示处所的名词。
  eg, The old man lives in a lonely mountain village.
注意: alone 强调客观上的 “独自。单独一人”, 而lonely除表示
“单独”外,还带有感情色彩,形容失去朋友,缺乏友爱和帮助,感到寂寞、甚至悲哀,它只能做形容词,在句中做表语,也可做前置定语,用于地点时,意为 “荒凉的,偏僻的”
eg, Though the old man is alone, he doesn’t feel lonely
二、probably adv. 很可能,或许,大概
  eg, Probably he may know the way. (放句首)
  He is probably about 50 years old. (放在系动词后面)
  I probably didn’t try hard enough. (放在谓语前面)
  It’ll probably rain. (放在助动词后面)
  able adj. 1. 有能力的,能干的
  eg, My father is an able engineer.
  用于be able to 结构,后跟动词原形。
   eg, Jim isn’t able to come tonight because he is ill.
三、be able to 与can :相同 点:两者后跟原形动词。
区别:
1. can是情态动词,无人称与数的变化。过去式是could.
be able to 可与情态动词连用,can却不能。
eg, I shall be able to speak English well.
2. be able to 可用在不定式之后,而can却不能。
 eg, I hope to be able to go shopping with you on Sunday.
3. be able to 的过去式还有表示过去经过努力而做到的意思,而could 没有这种意思。
 eg, He studied hard and was able to pass the exam.
4. can 表示请求和允许,以及猜测,而be able to 却无此用法。
 eg, Mr Smith can’t be at home.  Can I carry your bag?
5. 当表示现在或过去的“能力”时,两者可通用。
 eg, No one was able to/could answer the question.
