These natural_(disaster) have warned us that everyone should protect the environment. 答案:disasters 根据所讲解题步骤: ①定词性:观察题目,设空前有these +形容词natural,且设空处在主语位置,所以可确定该空需要填名词,而且需要是复数形式 ②变词形:所给词disaster本身是名词,所以在此只需变复数形式disasters即可 ③做检查:disasters词汇拼写无误,形式正确,带入句中符合语境,所以最终答案是disasters。 2. This Chinese medicine proved to be highly_(effectively) in curing the cold. 答案:effective ①定词性:观察题目,设空前有be 动词,同时有副词 highly,可确定设空处需要填形容词。 ②变词形:所给词effectively是副词,变形容词只需去掉ly变成形容词effective 即可, ③做检查:effective词汇拼写无误,形式正确,带入句中符合语境,所以最终答案是effective。 随堂巩固 用所给单词的适当形式完成下列句子 1.Many_ (tour) visit Shanghai every year. 2.It's_ (possible) for him to finish the work in one hour. 3.Shanghai is one of the most_ (beauty) cities in the world. 4.The boy was_ (luck) enough to win the first prize. 5.Please be_ (care) when you cross the busy street. 6.The_ (manage) of the hotel is very friendly. 7.The children enjoyed_ (they) at the birthday party. 8.He is a man of great_ (wise). 9.The famous _(science) will give a speech tomorrow. 10.The movie has a _(surprise) ending that no one expected. 11.The students are_ (interest) in this new topic. 12.Could you give me some_ (suggest) about learning English? 13.The old bike needs_ (repair).
