vt. & vi. 储存,节省1. If we do nothing, soon there may be none left! 2. The bamboo forests are becoming smaller and smaller. As a result, pandas may not have a place to live or food to eat. may 表示猜测,可能性(用于肯定句中
或否定句中)may not do... 意为“可能不......”may可用来表示猜测某件事发生的可能性,常译为“也许,可能”。may通常用于肯定句与否定句,一般不用于疑问句。
例如:
The news may or may not be true.
这消息也许是真的,也许不是真的。At the moment she may be playing with her classmates. 此刻她可能正在和同学们玩。For example1. The story may or may not be true. 2. Can that be true? √

It ___________ (need) a bath.may needDo part A[kl??zd] adj. 关闭的 B Using verbs + to-infinitives当我们要表示“想做某事、需要做某事
或决定做某事”时,就会出现两个动词
连用的情况,这时应如何表达呢?同学们自然会想到want to do sth.,
need to do sth.和decide to do sth.
等表达方式。Using verbs + to-infinitivesKitty is preparing to go out next
Sunday.
Kitty plans to take Linda out.
Linda wanted to visit the park.
Sandy agrees to go with them.
Millie decided to stay at home.Please go on to look at the sentences below. Pay attention to the colored words.上面例子中主要行为动词后面的动词
都采用了“to + 动词原形”的结构,我
们把这种结构称为动词不定式(有时
可以不带to)。动词不定式没有人称
和数的变化,在句子中不能单独作谓
语,其否定形式是“not to + 动词原形”。什么是动词不定式(‘to-infinitives’)?agree to do sth. 同意干
begin to do sth. 开始干
decide to do sth. 决定干
fail to do sth. 做某事失败
forget to do sth. 忘记干
hope to do sth. 希望干 在英语中某些及物动词后接动词不定式作宾语, 常用的此类动词有:learn to do sth. 学着干 plan to do sth. 计划干
prepare to do sth. 准备干
remember to do. 记得干
try to do sth. 尝试干
want to do. 想要干 More about animalsDad : Do you know anything special about wild animals?
Amy : Yes , Dad. For example, dolphins are clever. They can _______________ (learn, work out) easy maths problems.

Do part B learn to work outdecide to flyremember to come backbegin to save[b?t] n. 蝙蝠 [bi?] n. 蜜蜂 [l?st] adj.迷路的,迷失的 迷路 与…一样 [se?v] vt./vi.储存, 节省 1. 当我们猜测某件事发生的可能性时,常
用may来表示“也许”、“可能”。
2. 当句子中已经有谓语动词,而我们又要
表达不止一个动作概念时,其余的动词
可以使用非谓语形式表达。动词不定式
就是动词的一种非谓语形式,其肯定形
式是“to + 动词原形”,其否定形式是
“not to + 动词原形”。无人称、数和时态
的变化。ReflectionSummary1. 只带不定式(to +v.)的词,词组和句型的归纳to do sth.wantneeddecideprepareplanchooseagreelearnfailwishwaitseemhavehurryIt takes sb. some time to do sth.It’s +adj. (for sb.) to do sth.to do sth.ask sb.
