Ⅰ. Read and write the words.
读一读,仿照例子写单词。
例：wind(风)—windy(多风的)
1. cloud(云)—(多云的)
2. sun(太阳)—(阳光充足的)
3. rain(雨)—(阴雨的)
4. snow(雪)—(多雪的)

1.cloudy 2.sunny 3.rainy 4.snowy

根据例子“wind(风)—windy(多风的)”可知，是在名词后加“y”构成形容词。
1. cloud后加y变为cloudy；
2. sun后双写n加y变为sunny；
3. rain后加y变为rainy；
4. snow后加y变为snowy。

Ⅱ. Read and choose the right words.
读一读,选择恰当的单词补全句子。
A. What B. How C. Why
() 1. ______ about you?
() 2. ______ can you do on hot days?
() 3. —______ do you like rainy days?
—Because we can wear raincoats(雨衣)and play in the rain.
() 4. ______ is the weather like today?

1. B
2. A
3. C
4. A

1. “How about you?” 是固定搭配，用于询问对方的情况，所以此空填 How。
2. “What can you do...” 是常用表达，用于询问能做什么，此句问在炎热的日子能做什么，填 What。
3. 答语用 Because 回答，说明问句是用 Why 提问，询问喜欢雨天的原因。
4. “What is...like?” 是固定句型，用于询问某物或某事怎么样，此句问今天天气怎么样，填 What。

Ⅲ. Choose the right answers.
为下列各题选择恰当的选项。
() 1. It's windy. The boy is ______.
A. fly a kite B. flies a kite C. flying a kite
() 2. It's warm ______ Hangzhou.
A. in B. on C. to
() 3. It's fun to play football ______ my friends.
A. and B. with C. to
() 4. The library is ______ now.
A. close B. closed C. on

1. C
2. A
3. B
4. B

1. 句子中已有is，需用现在进行时表示正在进行的动作，结构为be+doing，所以选flying a kite。
2. “在杭州”用介词in，in用于指较大的地方，如城市、国家等。
3. “和某人一起”用with，play football with my friends表示和朋友们一起踢足球。
4. be动词后需用形容词，closed是形容词，表示“关闭的”，close作形容词时表示“接近的”，on表示“开着的”，根据句意图书馆现在关门了，所以选closed。
