参考答案：
1．A
【详解】句意：学习英语对我们每个人都很重要。
考查动名词和介词。根据句意，可知本句主语为“学英语”，动词词组learn English做主语时，需要变成动名词形式learning English，固定句型be important to“…对某人而言是很重要的”，而介词for 多用于句型be important for sb to do sth.做某事对某人重要，故选A。
2．B
【详解】句意：四分之一的苹果对我来说太大了。但是四分之三的水不太多。
考查主谓一致。these apples“这些苹果”，可数名词复数形式，所以这些苹果的四分之一是复数名词，谓语动词应为复数are，water“水”，不可数名词，所以它的四分之三也是不可数名词，谓语动词应为复数is，故选B。
3．D
【详解】句意：我们可以不吃太多肉来保持健康。
考查介词及动名词否定形式。根据句意，这里指我们通过不吃太多肉来保持健康。介词by，“通过，靠”，表示方法、方式，后接动词时要-ing形式。即 by doing sth。动词-ing形式的否定是在动名词前加not，即by not doing sth。而介词with常用于“with + 宾语 + 动词ing”（表示主动，正进行），故选D。
4．B
【详解】句意：睡觉前别忘了关掉电视。
考查动词词组辨析。A. turn on“打开”；B. turn off“关掉”；C. put out“熄灭”；D. look for“寻找”，根据句意“睡觉前别忘了关掉电视。”故选B。
5．C
【详解】句意：我们必须停止污染水、土地和空气。
A. pollute动词原形；B. to pollute不定式形式；C. polluting动名词形式；D. to polluting错误形式，根据句意，这里指停止污染环境，不要再污染环境了，停止正在做的事情“stop doing”，故选C。
【点睛】stop to do与stop doing的区别：
1.stop to do sth.意思是“停下来去做另外的事情”
如：Let's stop to have a break.咱们停下来休息一会儿。
2. stop doing 意思是“停下正在做的事情”
如：Stop talking please! 请停止说话。
6．the most dangerous 7．the best 8．the largest 9．dangerous 10．farmer
【解析】6．句意：老虎是陆地上最危险的动物之一。
根据句意， “……是……中最……之一”用one of the +最高级+名词(复数) 表示。所以用 dangerous“危险的”的最高级，根据dangerous的音标['de nd r s]，可知此词是一个三音节词，所以最高级为most dangerous，最危险的，故答案为the most dangerous。
7．句意：——你们班谁是最好的学生？——是Eddie。
根据in your class，可知在问谁是班级里所有人中最好的，所以用good的最高级the best，故答案为the best。
8．句意：世界上最大的海洋是哪一个？
根据in the world“在世界上”，可知在问哪个海洋是世界上最大的，所以用large的最高级形式the largest。
9．句意：不要玩火。很危险。
根据句意，这里指玩火这种行为是危险的，所以用danger的形容词形式dangerous做is的表语。故答案为 dangerous。
10．句意：Tom的叔叔是个农民。
根据farm“农场”提示，可知Tom 的叔叔是农民，farmer“农民”，可数名词，a 后面用farmer的单数，故答案为farmer。
【点睛】当有三者或三者以上的人/东西做比较的时候用最高级。在含有最高级的句子中，常有一个“in+名词”短语来表示比较范围。例如：he is the tallest boy in the class/in the team.介词in the class指的是班级里的所有人，体现他是最高的，in the team是指在一个组里的所有人当中，他是最高的。
11． How many 12． How can 13． Don't waste 14．sweeter
【解析】11．句意：只有四分之一的学生乘公共汽车上学。
Only a quarter of the就…的四分之一提问，可知在问“有多少学生乘公共汽车上学？”，学生是可数名词，所以用疑问词how many，故答案为(1)How (2) many。
12．句意：我们可以通过固定滴水龙头来节约用水。
by fixing dripping taps.就“通过固定滴水龙头”提问，可知在问“怎样节约用水”，所以用疑问词how，后加一般疑问句句式，把can 提前，故答案为(1)How (2)can。
13．句意：你千万不要浪费水。
You mustn't waste water. 你千万不要浪费水。mustn't表示禁止，也可以用祈使句“不要浪费水”，即Don't waste any water. 故答案为(1) Don't (2)waste。
14．句意：我在咖啡里放了很多糖。你在咖啡里放了更多的糖。
根据句意，可知你放的糖比我放的多，也就是你的咖啡比我的甜，甜“sweet”，形容词，根据句中than，可知两者比较，所以用形容词sweet的比较级sweeter，故答案为sweeter。
15．seas 16．with 17．cold 18．becomes 19．rain

15．句意：阳光照射在地球、河流、湖泊和大海的水上。
根据the rivers河流, the lakes湖泊和首字母提示，可知还有大海“sea”，从river ，lake用的是复数形式，表示地球上的河流和湖泊， 所以大海sea也用复数形式seas。故答案为seas。
16．句意：水蒸气与暖空气一起上升。
根据句意和首字母提示，这里指水蒸气随着暖空气一起上升， “with”，介词。表示“跟; 随着”。故答案为with。

根据常识和首字母提示，可知空中是冷的，冷的“cold”，形容词，与is构成系表结构。故答案为cold。
18．句意：水蒸气变成云。
根据常识和首字母提示，水蒸气遇冷变成云，变成“become”，动词，主语水蒸气the water vapour不可数名词，所以谓语become用单数形式becomes，故答案为becomes。
