2026年学霸提优大试卷七年级英语下册译林版第51页答案
三、阅读理解(每小题2分,满分30分)

A
How bloody a scene!
The "Blood Falls" in Antarctica is a waterfall which shoots blood-red water into a river. The sight is a perfect background for a horror film: mysterious and of course bloody. Its special colour was long believed to be caused by red algae. Until 2017, the true cause of the so-called blood was proved to be oxidized iron in saltwater.
Impressive yet a dangerous sight, frozen bubbles can be seen in winters at Abraham Lake in Canada. When methane gas gets crowded underwater and freezes, it will finally form this special sight—frozen bubbles. Such plenty of methane is highly risky. So even a lit match nearby can cause an explosion.
Mirror of the Sky
During the new moon and full moon periods, tourists can see a clear reflection of the sky in the waters of Sasaran Beach in Malaysia. The smooth sand and lowest water level create such an unbelievable sight. Also known as the "Mirror of the Sky", this water beach is an amazing place to take pictures and thus a perfect travel destination.

答案

A
【文章大意】本文是三则新闻,介绍了世界上的三个奇妙的自然景象。
26. D 文章出处题。本文介绍了世界上的三个奇妙的自然景象。因此可在报纸上的自然版块看到这篇文章。故选D。
27. A 细节理解题。根据"Its special colour was long believed to be caused by red algae. Until 2017, the true cause of the so-called blood was proved to be oxidized iron in saltwater."可知,血瀑布的特殊颜色长期以来被认为是由红藻引起的。直到2017年,造成所谓血液的真正原因被证明是盐水中的氧化铁。故选A。
28. C 补全文章题。根据"Impressive yet a dangerous sight, frozen bubbles can be seen in winters at Abraham Lake in Canada."可知,第二则新闻介绍的是在加拿大的亚伯拉罕湖,冬天可以看到冰冻的气泡,这是一个令人印象深刻但又很危险的景象。选项C"特别的冰冻气泡!"作为标题补充在此处最为合适。故选C。
29. B 推理判断题。根据"During the new moon and full moon periods, tourists can see a clear reflection of the sky in the waters of Sasaran Beach in Malaysia. The smooth sand and lowest water level create such an unbelievable sight."可知,在新月和满月期间,游客可以在马来西亚萨萨兰海滩的水域看到清晰的天空倒影。光滑的沙子和最低的水位创造了如此令人难以置信的景象。因此推断第三幅图片描绘的是一个穿着连衣裙的女孩倒映在水域海滩上。故选B。
30. D 推理判断题。根据"Its special colour was long believed to be caused by red algae. Until 2017, the true cause of the so-called blood was proved to be oxidized iron in saltwater."可知,血瀑布的特殊颜色长期以来被认为是由红藻引起的。直到2017年,造成所谓血液的真正原因被证明是盐水中的氧化铁。根据"When methane gas gets crowded underwater and freezes, it will finally form this special sight—frozen bubbles."可知,当甲烷气体在水下拥挤并结冰,最终会形成这种特殊的景象——结冰的气泡。根据"During the new moon and full moon periods, tourists can see a clear reflection of the sky in the waters of Sasaran Beach in Malaysia. The smooth sand and lowest water level create such an unbelievable sight."可知,在新月和满月期间,游客可以在马来西亚萨萨兰海滩的水域看到清晰的天空倒影。光滑的沙子和最低的水位创造了如此令人难以置信的景象。由此推断,这三则新闻的共同之处就是它们都解释了这些特殊景象的成因。故选D。

解析

【分析】
拿到这篇阅读理解,首先先通读全文,明确文本核心是介绍三处世界上奇特的自然奇观,再逐个对应题目梳理思路:
1. 第26题是文章出处题,先明确四个选项对应的报纸版块属性,再匹配全文介绍自然奇景的主题,就能选出对应版块。
2. 第27题是细节题,直接定位到Blood Falls对应的段落末尾,找到明确说明的血红色水体的真正成因,直接匹配选项即可。
3. 第28题是选段首小标题,先锁定第二段的核心描述对象是加拿大亚伯拉罕湖的冰冻气泡奇观,排除偏离核心的选项,选出最贴合段落主旨的标题。
4. 第29题是图文结合推理题,结合第三部分“天空之镜”水面能形成清晰倒影的特点,对应插图内容,排除不符合场景的错误描述。
5. 第30题是找三则内容的共同点,逐一核对每个选项,排除描述片面、不符合原文的选项,提炼三个段落共同的写作逻辑。
【解析】
26. 文章出处题:全文介绍了南极血瀑布、加拿大亚伯拉罕湖冰冻气泡、马来西亚萨萨兰海滩天空之镜三处奇特的自然景观,主题完全对应自然类内容,因此这类内容会出现在报纸的NATURE(自然)版块。A人物版块、B物理学科版块、C旅游版块都不符合全文的核心主题,因此选D。
27. 细节理解题:定位原文第一部分最后一句“Until 2017, the true cause of the so-called blood was proved to be oxidized iron in saltwater”,明确说明血瀑布水体呈血红色的真正原因是盐水中的氧化铁,红藻是之前人们误以为的原因,因此选A。
28. 选段标题题:第二部分全程围绕亚伯拉罕湖冬季的特殊景观“冰冻气泡”展开,既介绍了它的形成原理也提到了它的危险性,核心描述对象是冰冻气泡。A选项核心是湖、B选项只强调危险、D选项核心是爆炸,都偏离段落核心,只有C“Special frozen bubbles!”最贴合段落主旨,因此选C。
29. 推理判断题:第三部分介绍的“天空之镜”景观特点是水位极低、沙滩平整,水面像镜子一样能形成清晰倒影,对应插图内容,画面里的“两个倒立的人”实际是女孩在水滩里形成的倒影。A选项“女孩在天空跳舞”不符合现实,C选项“女士在拍照”不是图片核心呈现的内容,D选项“两个人位置颠倒”不符合事实,因此选B。
30. 推理判断题:逐一核对三部分内容:第一部分介绍了血瀑布红色水体的成因,第二部分介绍了冰冻气泡的形成原理,第三部分介绍了天空之镜景观的形成条件,三则内容都说明了特殊景观的形成原因。A选项“只能在水边看到”不符合血瀑布的属性,B选项“吸引大量游客”原文没有提及,C选项“都适合游览”不符合冰冻气泡景观危险的特点,因此选D。
