(猎豹的速度令人惊奇。) 【易错点】 -ing形容词常修饰物，-ed形容词常修饰人。 (2) protect (v.) 保护 考点： 及物动词，常与from/against连用。 搭配： protect... from/against... (保护……免受……伤害) 例句： We should protect animals from danger. 【易错点】 名词形式为 protection。注意介词搭配不要漏掉。 (3) dangerous (adj.) 危险的 考点： 作表语或定语。 搭配： be in danger (处于危险中); be dangerous to... (对……有危险) 例句： It is dangerous to swim in the river alone. 【易错点】 区分 danger (n. 危险) 和 dangerous (adj.)。It is + adj. + to do sth. 是常用句型。 (4) forest (n.) 森林 考点： 可数名词。 搭配： in the forest (在森林里) 例句： Many birds live in the forest. 【易错点】 注意拼写，中间是o不是e。rainforest (雨林)。 (5) survive (v.) 幸存；生存 考点： 不及物动词或及物动词。 搭配： survive from...

I didn't buy anything. no- 系列： 本身含否定意义，谓语动词用肯定形式。 There is nothing in the box. (= There isn't anything...) 形容词后置： 形容词修饰不定代词时，必须放在代词之后。 错：something new -> 对：something new 错：interesting anything -> 对：anything interesting 【主谓一致】 不定代词作主语时，谓语动词一律用单数。 Everything is ready. Everyone likes pandas. 四、经典句型与写作素材 1. 询问与描述经历 Q: What did you see in the nature park? (你在自然公园看到了什么？) A: I saw some amazing birds. They were singing in the trees. Q: Did you feed the monkeys?
