考点9 名词的派生变化
例题9:(长春中考)I will never forget that afternoon. Birds flew over the 3. (peace) lake. The mountains were covered with white snow.
解析:peaceful 此处用形容词作定语修饰lake，peace是名词“和平”，其形容词形式是peaceful。

训练18: (常州中考)China is known as the "home of the loong". The loong is considered to be 1. (luck) and wise.

训练17 carefully 根据“Gently and”可知，空处需填入副词，carefully 表示“小心地”，与“Gently”形式保持一致。
训练 18 lucky 根据“and wise”可知此处需要形容词作表语，luck 的形容词形式是 lucky“幸运的”。

例题 10:(哈尔滨中考)I tried to call her. 7. (twentieth) minutes later, their mother turned up. With tears in her eyes, she was very thankful to us.
解析:Twenty 根据“minutes later”可知,此处表示“二十分钟后”,需填基数词 twenty“二十”,句首单词首字母需大写。
训练 19: ★★ (青岛中考)Electricity ran down the wet string and gave him a small shock, which showed lightning was electricity for the 8. (one) time.

训练19 first for the first time“第一次”，固定短语，first 是 one 的序数词。
训练 20 second 根据“The ... layer”可知，此处指第二层，应填序数词表示顺序。

例题11:(苏州中考)Its use soon spread across Southeast Asia and then to the 8. (wide) world.
解析:wider wide是形容词。此处指甘蔗后来传播到更为广阔的世界，暗含比较，应用其比较级。

训练22: （枣庄中考）They want to teach their kids how to farm, so their kids will learn 10. (much) about science and nature than other children.

训练21 harder 根据“The judge began with a list of easy words, but soon the words got”可知是不久单词变难了，应用比较级 harder“更难的”。
训练 22 more 根据“than”可知，此处应使用 much 的比较级 more。

考点12 形容词/副词的最高级
例题12:(福建中考)In central Xi'an there is the Bell Tower—the 5. (large) bell tower remaining in China.

largest

本题考查形容词最高级的用法。句中给出的比较范围是中国现存的所有钟楼，空格前有定冠词the，提示词为形容词large，此处要表达“最大的”含义，因此需要将large变为对应的形容词最高级形式。
