Language points 用 “It’s + 形容词” 这个简单的句子来说明天气情况。 句型结构：It’s + 天气形容词（warm/hot/cool/cold等）. It’s 是 It is 的缩写，意思是“它是”，在这里指代“天气”。 这个句型用来描述天气的总体特征。 Language points 情态动词 can 表示“能力”或“可以” We can play in the snow. We can see white snow. Language points can 是一个情态动词，意思是“能、会、可以”。它表示某人具备某种能力，或者表示允许做某事。在句中，can 后面一定要跟动词原形。 句型结构：主语 + can + 动词原形 + 其他. 肯定句：We can play football. (我们会踢足球。) 否定句：We cannot (can’t) play football. (我们不会踢足球。) 疑问句：Can you play football? (你会踢足球吗？) 肯定回答：Yes, I can. 否定回答：No, I can’t. Language points 一般现在时（陈述客观事实和状态） The plants are green. The flowers are beautiful. Some trees are yellow. It is warm. Language points 这里我们描述的是自然现象和客观事实（植物是绿的，花是美的），这些状态在现在、过去和将来通常都是成立的，所以用一般现在时。主要注意 be 动词 (am/is/are) 的正确使用。 句型结构：主语 + be动词 (am/is/are) + 表语（形容词/名词等）. be动词选择口诀：I 用 am, You 用 are, Is 连着他(he)/她(she)/它(it), 复数主语全用 are。 e.g. It (单数) is warm.
