一、根据汉语提示填写单词。
1. You can call the police for help (如果) you are in danger.
2. The (信息) on the Internet is not always true.
3. Look! There is an (岛) in the middle of the lake.
4. You don't need to take a bus. (仅仅) walk along the road and turn left at the second crossing.
5. Be careful when you walk on the (冰).

1. if
2. information
3. island
4. Just
5. ice

1. 此处要表达“如果”的含义，引导条件状语从句，对应的英文单词是if，符合句子逻辑。
2. “信息”的英文表达是information，它是不可数名词，和句中be动词is的用法匹配。
3. “岛”的英文是island，空格前有不定冠词an，后面接以元音音素开头的单数名词，island符合要求。
4. 此处修饰动词walk，表达“仅仅”的含义，位于句首首字母需要大写，填Just。
5. “冰”的英文是ice，是不可数名词，符合“在冰上行走”的语境。

二、用括号内所给单词的正确形式填空。
1. Wang Fang would like to buy two (kilo) of strawberries.
2. The boy (improve) his English by speaking English every day.
3. The cat hid (it) under the bed, so Tom didn't find it.
4. —Are those your (key)?
—Yes, they are.
5. —How long is the Great Wall?
—It's more than twenty thousand (kilometer) long.
6. Every morning, the mother gives her little son sweet (kiss) when he wakes up.
7. Ted (kick) the ball and made a goal.
8. Last Friday, the host (introduce) the history of Kaifeng to the guests at the party.
9. The little (kid) were excited to visit the zoo with his family.
10. She ordered a delicious (Italy) pizza at the restaurant.

1. kilos
2. improves
3. itself
4. keys
5. kilometers
6. kisses
7. kicked
8. introduced
9. kids
10. Italian

1. 空前有数词two，后接可数名词复数，kilo的复数形式为kilos。
2. 句中时间状语every day表示经常性动作，用一般现在时，主语the boy是第三人称单数，谓语动词improve要变为第三人称单数形式improves。
3. 此处表达猫把它自己藏在床下，要用it的反身代词itself。
4. 句中those表示“那些”，后接可数名词复数，key的复数形式为keys。
5. 空前twenty thousand（两万）后接可数名词复数，kilometer的复数形式为kilometers。
6. 此处表示不止一个甜蜜的吻，要用可数名词kiss的复数形式kisses。
7. 句中and连接并列的谓语动词，后面的made是一般过去时，kick也要变为过去式kicked。
8. 时间状语Last Friday表示过去的时间，句子用一般过去时，introduce的过去式为introduced。
9. 句中be动词是were，说明主语是复数，kid的复数形式为kids。
10. 此处需要形容词修饰名词pizza，Italy对应的形容词是Italian，意为“意大利的”。

三、从方框中选择适当的短语并用其正确形式填空。每个短语限用一次。

1. —How long did you stay there?
—We planned to stay for an hour only, but , we stayed there for three hours.
2. , enough exercise is important for staying healthy.
3. Please remember to the door before you come in.
4. —Han Cheng, I called you , but you didn't answer the telephone.
—Sorry, I was taking a shower at that time.
5. —Are you clear about the job of a policeman, Ben?
—Yes, to keep people safe and the society .
6. , we can learn math well and get good grades.
7. These animals are dangerous. We must them.
8. Zhang Peng, your room is . Look at the books! They are everywhere.
9. There is a tree the house. Children like to play games under the tree.
10. We should always the traffic rules because they are good for us.

1. in the end

3. knock on
4. just now
5. in order
6. In this way
7. keep away from
8. in a mess
9. in front of
10. keep; in mind

我们结合每个句子的语境和方框内短语的含义逐一匹配：
1. 句意为我们原本计划只待一小时，但最后在那里待了三小时，对应短语in the end（最后）。
2. 句意为简言之，充足的锻炼对保持健康很重要，对应短语in short（简言之），句首首字母大写。
3. 句意为你进来之前请记得敲门，remember to后接动词原形，对应短语knock on（敲）。
4. 句意为我刚才给你打电话但你没接，对应短语just now（刚才），和后文过去进行时的时间提示匹配。
5. 句意为警察的工作是保障人民安全、让社会秩序井然，对应短语in order（秩序井然）。
6. 句意为用这种方法，我们可以学好数学取得好成绩，对应短语in this way（用这种方式），句首首字母大写。
7. 句意为这些动物很危险，我们必须远离它们，情态动词must后接动词原形，对应短语keep away from（远离）。
8. 句意为张鹏，你的房间一团糟，看这些书扔得到处都是，对应短语in a mess（一团糟）。
9. 句意为房子前面有一棵树，孩子们喜欢在树下玩游戏，对应短语in front of（在……前面）。
10. 句意为我们应该时刻牢记交通规则，因为它们对我们有好处，对应短语keep...in mind（牢记……），should后接动词原形。
所有短语都仅使用一次，符合题目要求。
