to ________ (clear) the room before the guests arrive. 【答案】clear 【详解】句意：我们需要在客人到达前打扫房间。clear“清理；打扫”，动词，need to后接动词原形，因此填动词原形clear。 87．The book ________ (belong) to my sister, so I can’t lend it to you. 【答案】belongs 【详解】句意：这本书属于我姐姐，所以我不能把它借给你。本句为描述一般事实，时态为一般现在时，belong“属于”，动词，句子主语The book为第三人称单数，因此填动词第三人称单数形式belongs。 88．I can ________ (hard) believe my eyes when I see the amazing view. 【答案】hardly 【详解】句意：当我看到这令人惊叹的景色时，我几乎不敢相信自己的眼睛。hard“努力的；困难的”，形容词，此处需要副词修饰动词believe，hardly表示“几乎不”，副词。 89．The ________ (wealth) man donated all his money to the poor children. 【答案】wealthy 【详解】句意：这位富有的男人把他所有的钱都捐给了贫困儿童。此处需要形容词修饰名词man，wealth是名词“财富”，其形容词形式是wealthy，意为“富有的”。 90．This is a ________ (history) story that tells us about the life of ancient people. 【答案】historical 【详解】句意：这是一个历史故事，向我们讲述了古人的生活。此处需要形容词修饰名词story，history是名词“历史”，其形容词形式是historical，意为“历史的、与历史相关的”。 91．The water is ________ (boil), so be careful not to get burned. 【答案】boiling 【详解】句意：水正在沸腾，所以小心不要被烫伤。句中be动词is提示此处为现在进行时，结构为be+现在分词，boil的现在分词是boiling；也可用boiling作形容词表示“沸腾的”。 92．There are ________ (end) problems in our life, but we should face them bravely. 【答案】endless 【详解】句意：我们的生活中有无穷无尽的问题，但我们应该勇敢面对它们。end“尽头，结束”，此处修饰名词problems需用形容词，end的形容词形式endless表示“无穷无尽的，无数的”，符合语境。 93．The ________ (believe) that dinosaurs could fly has been proved by new research. 【答案】belief 【详解】句意：恐龙会飞的信念已经被新的研究证实。此处需要名词作句子的主语，believe是动词“相信”，其名词形式是belief，意为“信念、看法”。 94．He was ________ (complete) shocked by the news that his team won the game. 【答案】completely 【详解】句意：他对自己队伍赢得比赛的消息感到完全震惊。此处需要副词修饰形容词shocked，complete是形容词，其副词形式是completely，意为“完全地”。 95．The flower in the amber ________ (prove) that the species existed 35 million years ago. 【答案】proves 【详解】句意：琥珀里的花证明这个物种在3500万年前就存在了。句子缺少谓语动词。句子描述的是客观事实，所以用一般现在时。主语“The flower”是第三人称单数，根据主谓一致原则，谓语动词要用第三人称单数形式。故填proves。 96．Wang Wencai ________ (carry) on with his research even after losing sight in one eye. 【答案】carried 【详解】句意：即使一只眼睛失明后，王文才仍继续他的研究。句子描述过去的事实，应用一般过去时。carry的过去式是carried。 97．We should put more ________ (effort) into nature exploration. 【答案】effort 【详解】句意：我们应该在自然探索上投入更多精力。“effort”作为名词，有“精力；努力”的意思。“put effort into...”是固定短语，意为“在……上投入精力”，这里“effort”通常用单数形式，表示抽象意义上的“精力投入”。故填effort。 98．Nature has many ________ (unsolved) secrets waiting for us to explore. 【答案】unsolved 【详解】句意：大自然有许多未解之谜等待着我们去探索。unsolved意为“未解决的”，是形容词。此处修饰后面的名词secrets，作定语。故填unsolved。 99．Amber is ________ (regard) as a window on the past by scientists. 【答案】regarded 【详解】句意：琥珀被科学家们视为了解过去的窗口。句中主语“Amber”与谓语动词“regard”之间为被动关系，表示“琥珀被视为”，应用被动语态。空格前“is”为be动词，后接过去分词构成被动语态。regard的过去分词为regarded，意为“被看作”，符合句意。 100．Could you please give me some ________ (piece) of paper? 【答案】pieces 【详解】句意：你能给我几张纸吗？some后接可数名词复数或不可数名词。piece是可数名词，意为“张、片”，在some后需变复数形式pieces，构成固定搭配some pieces of paper。 14 同步新教材，周周有练习，月月有重点！ 15 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $
