Eating three meals a day is important. But some people don’t have breakfast. Maybe they don’t feel hungry in the morning, or they are too busy to eat anything. But food gives us energy. It is easy to feel sleepy and find it hard to focus on our work or studies if we don’t eat breakfast.
too...to... 太......以至于不能
energy n. 能量；精力
maybe与may be 的区别
简言之：may be 是谓语动词 ，出现在谓语上
maybe 是副词 ，出现在句首或句中
maybe
adv. “可能；也许”,可用于句首或句中作状语。
may be 由情态动词may加系动词be构成的，意为“可能是；也许是”,与主语及后面所接的名词、形容词、介词短语等构成“主系表结构”。
But food gives us energy.
主 谓 宾
⑤ it is easy to feel sleepy and find it hard to focus on our work or studies (if we don't eat breakfast)
真正主语
形式主语
在英语中，当主语特别长的时候，为了避免“头重脚轻”，会将真主语“置后” it “替位”注意翻译顺序
=But food gives energy to us
※英语中有些动词类似throw , pass, lend, tell, show 等后面有人+物 双宾语时，人+物 可以调换位置，但人放后要加介词to
以下是一些主要的句型及用法：
①It + be + 形容词 + (for/of sb.) to do sth
It is important for us to learn English well. 对我们来说学好英语很重要。
It is kind of you to help me with my homework. 你帮我做作业，你真好。
②It + takes/took sb. + 时间/金钱 + to do sth.
用法：表示“做某事花费某人多少时间/金钱”
It took me two hours to finish my homework. 完成作业花了我两个小时。
