一、根据汉语提示填写单词。
1. Please speak in a loud （说话声）so that we can hear you clearly.
2. Look! Anna is cutting a （西瓜）into two halves.
3. Wang Yan likes folk music （然而）her brother enjoys rock music.
4. She does （志愿的）work at the library every weekend.
5. The Amazon River is a （宽的）river in the world.

1. voice 2. watermelon 3. while 4. voluntary 5. wide

1. 此处要填表示“说话声”的名词，固定搭配in a loud voice意为“大声说话”，空前有不定冠词a，填入单数名词即可。
2. “西瓜”的英文表达是watermelon，空前有不定冠词a，使用名词单数形式。
3. 此处需要表转折对比、意为“然而”的连词，连接两个并列分句，填入while符合句子逻辑。
4. 此处需要形容词修饰后面的名词work，“志愿的”对应的英文形容词是voluntary。
5. 此处需要形容词修饰名词river，“宽的”对应的英文形容词是wide。

二、用括号内所给单词的正确形式填空。
1. If you want to know more about Zhengzhou, you can look through some local (website).
2. They visited towns and (village) all over Spain last summer.
3. —Excuse me, are those bags (you)?
—Yes, they are mine.
4. She (waste) much money on clothes she didn't need last year.
5. —Do you help Maria to wash her clothes?
—No, she (wash) them by herself. She's now old enough to do that.

1. websites 2. villages 3. yours 4. wasted 5. washes

1. 空格前的some意为“一些”，后接可数名词时需要使用复数形式，website是可数名词，其复数形式为websites。
2. 并列连词and前后的成分形式要保持一致，前面的towns是可数名词复数，因此village也要变为复数形式villages。
3. 空格后没有名词，此处需要表达“你的（包）”的含义，要使用名词性物主代词yours，相当于your bags。
4. 句中的时间状语last year（去年）表示动作发生在过去，句子要用一般过去时，waste的过去式为wasted。
5. 此处描述的是客观事实，主语she是第三人称单数，一般现在时的谓语动词要使用第三人称单数形式washes。

三、从方框中选择适当的单词或短语并用其正确形式填空。每个单词或短语限用一次。

3. With the help of
4. wrong
5. worked for
6. work out
7. walk on
8. volunteers
9. wait for
10. until

1. 前后句语义递进，前半句说明做运动的好处是有益健康，后半句补充说明它还很有乐趣，what's more意为“而且，此外”，符合语境。
2. 根据后一句“我能好好照顾自己”，可知此处是让爸爸不要担心自己，don't后接动词原形，worry about意为“担心”，符合要求。
3. 句意为“在地图的帮助下，你可以轻松找到你想去的地方”，with the help of... 意为“在……的帮助下”，位于句首首字母需大写。
4. 句意为“到校之后我才意识到我拿错了课本”，wrong意为“错误的”，修饰名词textbook，符合语境。
5. 句意为“她哥哥18岁时就为国家篮球队效力”，时间状语从句是一般过去时，主句谓语动词要用过去式，work for意为“为……效力/工作”，过去式为worked for。
6. 句意为“Ted，你能帮我解出这道数学题吗？”，help sb. to do sth. 是固定搭配，后接动词原形，work out意为“算出，解决”，符合语境。
7. 这是祈使句，and连接并列的谓语，和前面的turn right形式一致，用动词原形，walk on意为“继续走”，符合指路的语境。
8. 句中be动词是are，说明主语是可数名词复数，volunteer意为“志愿者”，复数形式为volunteers，符合“志愿者们正在河两岸种树”的语义。
9. 句意为“如果我们错过了这班公交车，就不得不等下一班”，have to后接动词原形，wait for意为“等待”，符合语境。
10. 此处是固定结构not...until...，意为“直到……才……”，句意为“直到我的朋友给我解释，我才知道答案”，符合逻辑。
