Jiuzhaigou, located in Sichuan Province, is one of the most beautiful natural scenic spots in China. It was listed as a World Natural Heritage Site in 1992, and it is famous for its colourful lakes, waterfalls and snow-capped mountains.
The name “Jiuzhaigou” means “the valley of nine Tibetan villages”. There are nine traditional Tibetan villages in the valley, and the local people live in harmony with nature. The most amazing part of Jiuzhaigou is its lakes. The water of the lakes is in different colours-blue, green, turquoise and even red. The colours change with the light and the season, which makes the lakes look like precious gemstones. The reason for the colourful water is the special minerals (矿物质) and algae (藻类) in the lake bed, which shows the sunlight in different ways.
Jiuzhaigou has more than 100 lakes and waterfalls. The Nuorilang Waterfall is the most famous one. It is 27 meters high and 270 meters wide, and it is the widest calcified (钙化) waterfall in China. When the water falls down from the mountain, it makes a loud sound, and the water flies everywhere. Standing in front of the waterfall, you will feel the power of nature.
In addition to lakes and waterfalls, Jiuzhaigou also has beautiful forests and snow-covered mountains. The forest is home to many special animals and plants, such as giant pandas, golden monkeys and Chinese dove trees.
Jiuzhaigou is a place of natural beauty. It is a gift from nature to humans. However, it was once damaged (破坏) by an earthquake in 2017.

【导语】本文讲述了作者和家人去森林公园的一次旅行，通过亲近自然，感受到自然的美好与馈赠，领悟到要爱护自然、与自然和谐相处的道理。
1．句意：去年春天，我和家人去了森林公园，那次旅行让我意识到自然是多么令人惊叹。
结合前文“Nature is full of wonders”和“enjoy its beauty and power”，自然是“令人惊叹的”，应选用amazing。common“普通的”、boring“无聊的”、terrible“糟糕的”均不符合语境。
2．句意：空气很清新，我们能听到鸟儿在树上欢快地歌唱。
结合欢快的氛围，鸟儿是“欢快地”歌唱，应选用happily。sadly“悲伤地”、angrily“生气地”、quietly“安静地”均不符合语境。
3．句意：在路上，我们看到了不同种类的植物——五颜六色的花、绿色的树和一些小灌木。
结合“colorful flowers, green trees and small bushes”，这些都属于“植物”，应选用plants。books“书”、clothes“衣服”、pens“笔”均不符合语境。
4．句意：我妈妈告诉我，大自然给了我们许多礼物，比如干净的空气和新鲜的水。
结合“clean air and fresh water”，这些都是大自然的“礼物”，应选用gifts。troubles“麻烦”、problems“问题”、stories“故事”均不符合语境。
5．句意：当我们回家的时候，我不想离开。
引导时间状语从句，表示“当……时候”，应选用When。Because“因为”、So“所以”、But“但是”均不符合逻辑。
6．句意：它给我们带来快乐，我们应该保护它。
结合后文“protect nature”，我们要“保护”自然，应选用protect。destroy“破坏”、ignore“忽视”、waste“浪费”均不符合语境。
7．句意：如果我们热爱并保护自然，它将永远美丽。
引导条件状语从句，表示“如果”，应选用If。Unless“除非”、Though“虽然”、Until“直到”均不符合逻辑。
8．句意：每当我感到疲惫时，我就会想起那次旅行和大自然令人惊叹的美丽。
结合前文“enjoy its beauty”，此处指自然的“美丽”，应选用beauty。noise“噪音”、danger“危险”、mess“混乱”均不符合语境。
9．句意：它让我开心，更热爱生活。
结合“love life more”，自然让我“开心”，应选用happy。worried“担忧的”、upset“沮丧的”、nervous“紧张的”均不符合语境。
10．句意：让我们与它和谐相处。
指代前文的“nature”，用代词it。him“他”、her“她”、them“他们/它们”均不符合指代逻辑。
11．A 12．C 13．A 14．B 15．C 16．C 17．D 18．B 19．C 20．D
【导语】本文介绍了死海的地理特征、特殊现象 (高盐度、易漂浮)、旅游价值、健康作用以及面临的环境危机。
11．句意：它的表面海拔约为负430米，是地球上陆地上的最低点。
根据下文“about 430 meters below sea level”，低于海平面430米，这是指湖面表层的海拔高度，对应选用surface“水面/湖面”。depth指水体深度 (水面到水底)、bottom指湖底、shore指岸边，三者都不能搭配海拔数值描述地表高程，尤其depth和海拔概念完全无关，因此只能选surface。
12．句意：这里的盐分比普通海水高出近十倍，造就了一个极具挑战的生存环境，几乎没有生物能在此存活。
根据前文“salt nearly ten times higher than normal seawater”，高盐环境严苛难生存，所以选challenging“有挑战性的、严苛的”。common“普通的”、friendly“友好的”、perfect“完美的”都不符合高盐难存活的语境。
13．句意：这里的盐分比普通海水高出近十倍，造就了一个极具挑战的生存环境，几乎没有生物能在此存活。
根据前文“challenging environment”，高盐环境不利于生命存续，所以选survive“存活、生存”。appear“出现”、develop“发展”、grow“生长”都不符合“几乎没有生物能存活”的句意逻辑。
14．句意：尽管生存环境恶劣，死海每年仍能吸引数百万游客前来游览观光。
根据后文“Visitors come not for swimming”，Visitors指代前来游玩的人群，所以选travellers“游客、旅行者”。scientists“科学家”、locals“当地人”、fishermen“渔民”都和游玩观光的语境不匹配。
15．句意：游客前来不是为游泳，而是想体验能轻松漂浮在水面上的独特乐趣。
根据常识“float effortlessly”，漂浮只会发生在水体表层，所以选surface“水面、表面”。bottom“水底”、depth“深度”、shore“岸边”都不符合漂浮的位置逻辑。
16．句意：科学家依旧对这片富含矿物质的水域充满好奇，人们认为这里的水有疗养功效。
根据后文“have healing properties”，特殊的水域特质会引发科研探索欲，所以选curious “好奇的”。bored“无聊的”、worried“担忧的”、certain“确定的”都与科研探究的态度不符。
17．句意：很多人专程来这里治疗皮肤病，因为它被视作全球最早的天然疗养胜地之一。
根据前后句逻辑，前半句讲前来疗养的行为，后半句说明背后原因，所以选as“因为”。if “如果”、unless“除非”、though“虽然”都衔接不了因果关系。
18．句意：但在死海游泳需格外谨慎，海水不慎入眼会存在风险，因此建议佩戴护目镜。
根据前文“requires caution”，海水入眼是危险情况，所以选risky“有风险的、危险的”。unusual“不寻常的”、dead“死寂的”、wonderful“绝佳的”都不符合警示提醒的语境。
19．句意：死海水位逐年下降、面积不断缩小，因此若不加以保护，这片独特之地未来或将消失。
根据前后句逻辑，前半句讲湖泊萎缩的现状，后半句引出后续消极结果，所以选As a result “因此”。After all“毕竟”、In addition“此外”、On the contrary“相反”都衔接不了因果推导关系。
20．句意：目前，死海仍是一个极具吸引力的旅游胜地，既能让人放松身心，又能满足人们的科学好奇心。
根据后文“offers both relaxation and scientific curiosity”，兼具休闲与科研价值的景点十分独特吸睛，所以选fascinating“迷人的、极具吸引力的”。common“普通的”、dangerous “危险的”、ordinary“平平无奇的”都不符合“兼具休闲与科研价值”这一独特优质的景区定位。
21．A 22．B 23．C 24．A 25．A 26．A 27．B 28．C 29．A 30．B
【导语】本文讲述了作者与家人去山里旅行，沿途欣赏自然美景，并由此感悟到要珍惜和保护大自然。
21．句意：我们沿着一条小路走，两旁是高高的树，长满了绿色的叶子。
根据上下文，“trees with green…”指树的部分，且与绿色相关，leaves最符合。
22．句意：我拿出手机，捕捉到了它活泼的瞬间。
前文说小妹妹指着一只可爱的松鼠让我拍照，lively符合松鼠的生动形象。sad悲伤的、quiet安静的、boring厌烦的，均与松鼠的可爱、生动不符。
23．句意：我们可以看到一条清澈的河流穿过山谷，它清澈的水在阳光下闪闪发光。
前文提到“clear river”，后文“sparkled in the sun”说明水清澈透明，clear符合。
24．句意：我对自然的这个伟大奇迹产生了深深的敬意。
前文父亲说这条河滋养了数百年的动植物，是对自然力量的赞叹，wonder符合，problem问题、gift礼物和secret秘密，均不符合句意。
25．句意：它们一起以整齐的一排移动，真是神奇。
前文说“a group of birds flying across the sky”，后文“moved together in a neat …”强调队形，line符合鸟类飞行常见队形。
26．句意：我妹妹说她以前从未见过如此美妙的景象。
前文描述的是鸟群飞行的景象，属于“景色、景象”。
27．句意：瀑布的水雾让我们的脸湿湿的。
水雾会使脸湿润，wet符合逻辑。dry“干的”相反，hot“热的”和cold“冷的”虽可能但无提示，且水雾直接效果是湿润。
28．句意：这是我见过的最美的景色之一。
前文描述瀑布景象，scenes正确。animals动物、plants植物、people人们，均与前文瀑布不符。
29．句意：我决定保护自然，永远保留它的美丽。
全文强调自然之美，作者希望保护并保留其美丽。
30．句意：自然是我们最好的朋友，我们应该永远珍惜自然的每一部分。
自然是由每一“部分”组成的，表示珍惜自然的每一个方面。book“书”、story“故事”、picture“图片”均不符合。
31．B 32．A 33．B 34．C 35．C

36．第一段结尾处“it is famous for its colourful lakes, waterfalls and snow-capped mountains”，说明九寨沟的特色有色彩斑斓的湖泊、瀑布和雪山，没有古代建筑。
37．第二段“The reason for the colourful water is the special minerals and algae in the lake bed, which shows the sunlight in different ways.”，说明九寨沟的湖水色彩斑斓的原因是湖底特殊的矿物质和藻类，它们以不同的方式反射阳光。
