need 怎么区分是情态动词还是实义动词?
Someone needs to cover them...
Someone need cover them...
Someone needs to cover them...(正)
Someone need cover them...(误)
need 后面的不定式带 to,是“实意动词”;不带 to 则是“情态动词”。
但是,情态动词 need 不能用于肯定句,只用于疑问句和否定句。
正误判断:
1. They need go. (误)
2. They need to go. (正)
3. Need they go? (正)
4. Need they to go? (误)
5. Do they need go? (误)
6. Do they need to go? (正)
7. They needn't go. (正)
8. They needn't to go. (误)
9. They don't need go. (误)
10. They don't need to go. (正)
