一、根据句意和所给首字母写出单词
1. My father o a new computer online this morning.
2. Use of computers s rapidly during those ten years.
3. Mr Li l the newspapers on the desk and left his office.
4. To my surprise, the house is a c mess.
5. Jack paid his b for the newspapers at once.

1. ordered
2. spread
3. laid
4. complete
5. bill

1. 根据语境“网上订购电脑”以及时间状语this morning（过去时间），结合首字母o，填order的过去式ordered；2. 描述过去十年间电脑使用的普及情况，首字母s，填spread（过去式，spread的过去式与原形一致）；3. 结合语境“把报纸放在桌上”，且后面left为过去式，首字母l，填lay的过去式laid；4. 固定搭配a complete mess表示“一团糟”，首字母c，填形容词complete；5. 根据语境“付报纸的账单”，首字母b，填bill。

二、根据句意，用括号中所给单词的适当形式填空
1. The meeting will go (smooth) if the boss is in a good mood.
2. The education system must (satisfy) the needs of all children.
3. Some computer (virus) can damage a computer's memory or steal a user's personal information.
4. Tim's uncle is a (manage) of a big foreign company.
5. Children should learn how to behave (proper) in public places.

1. smoothly
2. satisfy
3. viruses
4. manager
5. properly

1. 此处需用副词修饰实义动词go，smooth的副词形式是smoothly，意为“顺利地”。
2. must是情态动词，后接动词原形，satisfy为动词，意为“满足”，故填原形。
3. some后接可数名词复数或不可数名词，virus是可数名词，其复数形式为viruses。
4. a后接可数名词单数，manage的名词形式manager意为“经理”，符合语境。
5. 此处需用副词修饰动词behave，proper的副词形式是properly，意为“得体地”。
