【分析】
本题考查英语词形转换及基础语法,需结合句子结构、固定搭配和语法规则确定每个空的正确形式:
1. 第一题:主语是悉尼歌剧院,与shape是被动关系,需用一般现在时的被动语态;
2. 第二题:固定搭配“one of + 形容词最高级”表示“最……之一”,需用形容词最高级;
3. 第三题:谓语动词是原形play,主语需用复数形式,故名词变复数;
4. 第四题:修饰名词places,需用形容词,故将名词变为形容词;
5. 第五题:固定搭配turn...into...后接名词,需将形容词变为名词。
【解析】
1. 第一题:考查被动语态。主语The Sydney Opera House是单数,一般现在时被动结构为“is + 过去分词”,shape的过去分词是shaped,故填is shaped;
2. 第二题:考查形容词最高级。固定搭配“one of + the + 形容词最高级 + 名词复数”,cheap的最高级为cheapest,故填cheapest;
3. 第三题:考查名词复数。谓语动词play是原形,主语需用复数,officer的复数为officers,故填officers;
4. 第四题:考查形容词。此处修饰名词places,需用suit的形容词形式suitable,故填suitable;
5. 第五题:考查名词。固定搭配turn...into...后接名词,real的名词形式为reality,故填reality。
【答案】
1. is shaped
2. cheapest
3. officers
4. suitable
5. reality

【解析】1. 句意:古代铁制农具的快速传播极大提高了粮食产量。修饰名词spread需形容词,rapid(快速的)符合语境,故填rapid。2. 句意:纸发明前,重要文本有时写在石头上。stone是可数名词,表泛指用复数形式,故填stones。3. 句意:最早的手机比现在的超薄智能手机更大更贵。由than可知用比较级,expensive是多音节形容词,比较级加more,故填more expensive。4. 句意:每一个新想法的诞生都需要挑战旧方法的勇气。every后接名词,birth(诞生)符合语境,故填birth。5. 句意:某些材料如玻璃、塑料是偶然发现的,后来成为许多发明的必需品。修饰名词materials需形容词,且在句首首字母大写,故填Certain。
