一、根据汉语提示填写单词。
1. His face turned (苍白的) when he heard the unexpected bad news.
2. Many (乘客) choose to read books or listen to music when they are waiting for the train.
3. She bought a (紫色) backpack because it was her favourite colour.
4. She ordered two large (披萨) for the party last weekend.
5. (粥) is very easy and quick to cook when you are in a hurry.

1. pale
2. passengers
3. purple
4. pizzas
5. Porridge

1. 系动词turn后需接形容词作表语，“苍白的”对应的英文形容词是pale，turn pale是常用搭配，意为“变得苍白”。
2. 形容词many后要接可数名词复数形式，“乘客”的英文是passenger，复数形式为passengers。
3. 此处需要形容词修饰名词backpack，“紫色”对应的形容词purple可作定语，意为“紫色的”。
4. 数词two后接可数名词复数，“披萨”的英文是pizza，复数形式为pizzas。
5. “粥”的英文是porridge，为不可数名词，在句首作主语，首字母需要大写。

二、用括号内所给单词的正确形式填空。
1. She (pack) her suitcase very quickly for her trip because she was almost late.
2. We learned about several important (president) in our history
class today.
3. The children were excited because they ate lovely (pancake) shaped like animals.
4. If you work with responsible and kind (partner), the task will become easier.
5. The factory makes electronic (product) like mobile phones and smart watches.
6. Nobody likes being (punish), so we should always follow the rules.
7. Can you understand the main idea of these difficult (passage) by yourself?
8. They practised hard for many weeks before (perform) their short play.
9. A lot of (poet) enjoyed writing (poem) about nature and love.
10. He (press) the red button several times but nothing happened.

1. packed
2. presidents
3. pancakes
4. partners
5. products
6. punished
7. passages
8. performing
9. poets; poems
10. pressed

1. 句中原因状语从句使用了一般过去时（was），主句的动作也发生在过去，因此要使用动词pack的过去式packed。
2. 限定词several意为“几个”，后接可数名词的复数形式，president是可数名词，变为复数presidents。
3. 此处指代多块造型像动物的煎饼，没有单数限定词，要用可数名词pancake的复数形式pancakes。
4. 此处表示和多名负责任、友善的搭档合作，要用可数名词partner的复数形式partners。
5. 后文列举了手机、智能手表等多款电子产品，要用可数名词product的复数形式products。
6. 此处表达“被惩罚”的被动含义，被动语态结构为be+动词过去分词，punish的过去分词是punished。
7. 限定词these意为“这些”，后接可数名词的复数形式，passage变为复数passages。
8. 此处before是介词，介词后要接动词的动名词形式，perform的动名词是performing。
9. a lot of后接可数名词时要使用复数形式，第一空表示“诗人”，poet的复数是poets；第二空表示创作多首诗歌，poem的复数是poems。
10. 后半句“nothing happened”是一般过去时，整个句子描述过去发生的动作，因此用press的过去式pressed。
