4. 形容词difficult描述“学生完成复杂实验”这件事的性质,属于for类句型,故填for。

【分析】
本题考查固定句型“It is + 形容词 + for/of sb to do sth”中介词的辨析。解题思路:判断句型中形容词的修饰对象,若形容词可直接描述人的品质、性格特征(即“sb + be + 该形容词”成立),则用介词of;若形容词描述做某事的性质(如难易、作用等,不可直接修饰人),则用介词for,据此逐个分析各句选择正确介词。
【解析】
1. 句中形容词generous(慷慨的)可直接修饰人,“Yuan Longping is generous”逻辑成立,故用of;
2. 句中形容词difficult(困难的)描述做某事的性质,不可直接修饰人,“young people is difficult”逻辑不成立,故用for;
3. 句中形容词thoughtful(体贴的)可直接修饰人,“my teacher is thoughtful”逻辑成立,故用of;
4. 句中形容词helpful(有帮助的)描述做某事的性质,不可直接修饰人,故用for;
5. 句中形容词selfless(无私的)可直接修饰人,“Norman Bethune is selfless”逻辑成立,故用of。
【答案】
1. of 2. for 3. of 4. for 5. of

本题考查英语词汇的词性转换及常用句型中的词形运用,解题思路为:先判断每个句子所需的词性,再结合所给单词的变形规则(如-ing/-ed形容词的区别、形容词与名词的转换)确定正确形式。
【解析】
1. 句型“It is + adj + that从句”中,需用形容词修饰事物(that从句描述的事件),amaze的-ing形式amazing用于修饰事物,故填amazing;
2. 句型“It is + adj + of sb to do sth”中,需用形容词,所给单词wise本身为形容词,直接使用,故填wise;
3. 空格修饰名词story,需用形容词,inspire的-ing形式inspiring用于修饰事物,故填inspiring;
4. 句型“It is + adj + to do sth”中,需用形容词,courage的形容词形式为courageous,故填courageous;
5. 名词所有格Norman Bethune's后需接名词,brave的名词形式为bravery,故填bravery。
【答案】
1. amazing 2. wise 3. inspiring 4. courageous 5. bravery
