A 【解析】细节理解题。根据第一段“There are around 300 different kinds of octopuses”可知，世界上大约有300种章鱼，B（2.5）、C（5）、D（9）均是章鱼的尺寸数据，并非种类数量，故选A。 2. B 【解析】细节理解题。根据第二段“Octopuses can also fit into small places because they do not have any bones!”可知，章鱼能钻进小地方是因为它们没有骨头，A（8条手臂）、C（3颗心脏）、D（会变色）均是其特点，但并非对应原因，故选B。 3. C 【解析】细节理解题。根据第三段“When they produce ink, the ink makes it hard for other animals to see them. This helps the octopuses to get away fast.”可知，章鱼喷墨是为了帮助自己快速逃跑，A（看起来像植物）、D（改变形状）是其另一项能力，B（长出手臂）与喷墨无关，故选C。 4. C 【解析】细节判断题。根据第三段“What's more, when an octopus loses an arm, it can grow it back!”可知，章鱼失去手臂后能重新长出来，C项“它们不能长出丢失的手臂”与原文相反；A（大脑在头部和手臂）、B（有些章鱼超过9米长）、D（3颗心脏为身体工作）均符合原文，故选C。 5. B 【解析】主旨大意题。短文从“章鱼的种类和尺寸”“身体特点”“神奇能力”三个方面介绍章鱼，核心是展现章鱼的神奇之处，A（如何养章鱼当宠物）、C（解释章鱼为何是最大动物）、D（让人们捕捉更多章鱼）均无依据，故选B。 二、阅读表达（每题3分，满分15分） 1. Only 2.5 cm long. 【解析】细节理解题。根据第一段“The smallest is only around 2.5 centimetres long”可知，最小的章鱼约2.5厘米长，简洁概括，控制在10词内。 2. In its head and arms. 【解析】细节理解题。根据第二段“Their brain is not just in their head, but also in their arms!”可知，章鱼的大脑在头部和手臂里，提炼地点。 3. Three. 【解析】细节理解题。根据第二段“And did you know that octopuses have three hearts?”可知，章鱼有3颗心脏，直接回答数字。 4. Colour and shape. 【解析】细节理解题。根据第三段“Most of them can change their colour and shape to look like plants or other sea animals”可知，章鱼能改变颜色和形状，提炼核心名词。 5. We can learn a lot from them. 【解析】细节理解题。根据最后一段“Studying amazing animals like the octopus is important because we can learn a lot from them.”可知，研究章鱼很重要是因为我们能从它们身上学到很多，简洁作答。 三、短文还原（七选五）（每题2分，满分10分） 1. B 【解析】前句讲“章鱼是世界上最奇怪、最特别的动物之一”，后句讲“它们大小不一”，B项“大约有300种不同的章鱼”承接前句，介绍章鱼的种类，引出后句的“大小差异”，逻辑连贯。 2. A 【解析】前句讲“章鱼的身体很有趣”，后句讲“它们的大脑不仅在头部，还在手臂里”，A项“所有章鱼都有8条手臂”承接“身体特点”的话题，引出后文关于“手臂里的大脑”的介绍，衔接自然。 3. E 【解析】前句讲“大脑帮助它们同时做几件事”，后句讲“因为它们没有骨头”，E项“章鱼还能钻进小地方”填补中间内容，后句的“没有骨头”正是“钻进小地方”的原因，形成“特点+原因”的结构。 4. C 【解析】前句讲“章鱼还能做很多神奇的事”，后句讲“它们还能喷墨”，C项“大多数章鱼能改变颜色和形状”是章鱼的神奇能力之一，与后句的“喷墨”构成并列关系，符合语境。 5. F 【解析】前句讲“喷墨让其他动物很难看到它们”，F项“这帮助章鱼快速逃跑”承接前句，解释“喷墨”的目的，让句子逻辑完整，与原文内容一致。 四、用所给单词的正确形式填空（每题1分，满分10分） 1. strange 【解析】“as+形容词原级+as”是固定结构，意为“和……一样……”，strange（奇怪的）本身是原级，无需变形。 2. kinds 【解析】kind是可数名词，前面有“300 different”（300种不同的）修饰，需用复数形式kinds。 3. long 【解析】“数词+单位+long”表示“……长”，long此处是形容词，用原级，符合“2.5厘米长”的表达。 4. arms 【解析】arm是可数名词，前面有“eight”（8条）修饰，需用复数形式arms。 5. their 【解析】修饰名词“arms”（手臂）需用形容词性物主代词，they的形容词性物主代词为their（它们的）。 6. (to) do 【解析】“help sb. (to) do sth.”是固定句型，意为“帮助某人做某事”，to可省略，此处填do或to do均可（七年级常用原形do）。 7. to look 【解析】此处用动词不定式“to look like...”作目的状语，表“改变颜色和形状”的目的是“看起来像植物或其他海洋动物”。 8. bag 【解析】不定冠词“a”后接可数名词单数，bag（袋子）本身是单数形式，无需变形。 9. loses 【解析】此处是when引导的时间状语从句，主句时态为一般现在时（can grow），从句也用一般现在时；主语“an octopus”是第三人称单数，谓语动词lose用第三人称单数形式loses。 10. is 【解析】主语“Studying amazing animals like the octopus”（研究章鱼这类神奇动物）是动名词短语，视为单数；时态为一般现在时，be动词用is。 五、书面表达（满分15分） 【范文】 Dear Tom, I want to tell you about an amazing animal—the octopus. There are about 300 kinds of octopuses. They have eight arms, three hearts and no bones. Their brains are in both heads and arms. Octopuses can do many wonderful things.
