学校：___________姓名：___________班级：___________考号：___________

一、阅读理解

Best Campgrounds in U.S. National Parks

Gold Bluffs Beach Campground, Redwood National & State Park, CA

    The remote campground is located about 6 miles up unpaved Davison Road. This is a small campground, though, with only 26 sites. So you’ll need to book your site well in advance. As far as facilities go, there are solar showers, barbecues and fire pits, picnic tables and food lockers-more than enough for a remote camping adventure. Note that the first part of Davison Road is very steep and winding. Large RVs(房车) are prohibited on this road.

    Nightly rate: $35

Watchman Campground, Zion National Park, UT

    There are five different loops(圈): Loop A and B have electric campsites, while the C and D are tent-only. Loop E is where the group sites are. Note, however, that this campground is extremely popular. Reservations are absolutely recommended from March through November. The off-season, on the other hand, offers first-come, first-served camping.

    Nightly rate: $30 for an electric site; $20 for a tent-only site

Pi ñon Flats Campground, Great Sand Dunes National Park, co

    As an International Dark Sky Park, Great Sand Dunes is also a great place to see the Milky Way and amazing views of North America’s tallest sand dunes. It is popular among children and adults alike. Renting a sled or sand board for an afternoon of fun—you’ll feel like a kid again. Sites can accommodate both RVs and tents.

    Nightly rate: $20

Painted Desert, Petrified Forest National Park, AZ

    It’s a fantastic place to put up a tent. This is free camping, wild camping. The only thing you have to do to camp there is to get a permit in person at the Painted Desert Visitor Center. Once you’re a mile from the trail head, you’re free to set up tents wherever you want. Remember to obey the Leave No Trace principles, though! Of course, there are no facilities in this desert wilderness. So, you’ll need to pack everything you need, from water and food to other supplies.

C. Great Sand Dunes National Park. D. Petrified Forest National Park.

    Last September an American started a trip through Southwest China on a standard bike she had bought at a local shop. In three months, Jennifer Holstein cycled 2,500 kilometers through three provinces with just two small bags.

Living in Beijing, her life was already great. But Holstein felt the urge to travel the world and look for adventure. It was mid-August of 2021 that the idea came to her to travel China by bicycle. At that time, Holstein had never cycled for more than 20 kilometers around her local city of Beijing.

    Holstein shared an experience from the beginning of her trip when she found herself stuck in a tunnel(隧道) with a flat tire. It was dark and hot, and she was so scared because she had never changed a tire before. Suddenly, a group of cyclists old enough to be her grandparents came and rescued her.

    In addition to receiving the kindness of people across China, Holstein also experienced several unique cultural experiences by attending three local weddings. She spoke about one wedding in detail, “I was in the middle of a small village in Sichuan province, and I was taken into a local Tibetan family’s home and they invited me to take part in a wedding. They gave me a dress and even did my makeup. I never thought I would ever have the chance to take part in a Tibetan wedding.”

    According to Holstein, “Many people want to travel the world and take huge risks, but never do. Don’t just live your life hoping your wildest dreams will become a reality someday. Try first and the rest will work itself out.” In addition to biking for her own passion and curiosity, Holstein also linked her ride to raise 22,000 yuan for the United Foundation for China’s Health.

4、Why did Jennifer Holstein decide to travel by bicycle?

A. Her life in Beijing was dull. B. Her friends encouraged her to go.

C. She was pushed by an inner desire. D. She was an experienced bike traveler.

5、How did the cyclists treat Jennifer Holstein in the tunnel?

A. They called an old man to help her.

B. They helped her fix the tire problem.

C. They ignored her and moved forward.

D. They thought themselves too old to help her.

6、What can be inferred from Jennifer Holstein’s words in paragraph 4?

A. She was fond of attending Tibetan weddings.

B. She was a bit annoyed at the wedding’s details.

C. She was forced to take part in the local wedding.

D. She was grateful for such an unexpected opportunity.

7、What’s the main idea of the text?

A. Lending a helping hand to the needy.

B. Enjoying the pleasure of travel.

C. Discovering the unknown on a bicycle.

D. Having a unique cultural experience in China.

    A flood hit Yellowstone National Park on June 13, 2022. The disaster was caused by a combination of unusually heavy rains and rapid snow melt. The high and fast water flows destroyed bridges and swept away entire roadways, leaving communities and homes isolated. Fortunately, the approximately 10,000 park visitors were safely evacuated.

    The town of Gardiner, along the Montana-Wyoming border, was particularly hard hit. The floodwaters left almost 900 people with no power or water for many days. Gardiner’s economy, which depends on the almost three-quarters of a million visitors who pass through the park’s north gate annually, is likely to take a hit. The floodwaters severely damaged the main north entrance road to Yellowstone, and could take years to rebuild.

    Park officials have begun work on improving an alternative road to Gardiner. This will ensure that locals can access food, supplies, and other essential emergency services. A limited number of tourists may also be allowed into Gardiner once the road is stable.

    Yellowstone’s north gate is closed indefinitely. But the park’s south gate opened to visitors on June 22, 2022. Park officials have started a new entry system to prevent overcrowding. It is based on the last number of the visitor’s vehicle license plate and the calendar date of the month. Cars with odd(奇数的) numbers can visit the park on odd days of the month, while those with even(偶数的) numbers can go on even days.

Established in 1872, Yellowstone is America’s oldest national park. The 3,472-square-mile reserve spans three states and is home to many unique wildlife. It is known for its natural beauty that includes mountains, rivers and lakes. The forces of fire and ice shaped the park over thousands of years.

8、What does the underlined word “isolated” in paragraph 1 probably mean?

A. Tracked. B. Separated. C. Decorated. D. Improved.

9、What was the possible result of the flood?

A. Gardiner’s economy would get into trouble.

B. Communities and homes were left in ruins.

C. Almost 900 people were trapped in the park.

D. The park’s south gate was closed for a while.

10、What can be inferred from the text?

A. Local people can get daily necessities from visitors.

B. The park has adopted a new system to recognize faces.

C. The license plate number decides when cars enter the park.

D. More tourists may flood into the park for geological features.

11、Which of the following statements is true according to the text?

A. Flooding has caused widespread damage in the US.

B. Yellowstone National Park is closed due to flooding.

C. People can visit Yellowstone National Park any day.

D. Natural beauty makes Yellowstone famous.

    This journey began this morning almost an hour later than I had planned, although I had completed my packing before eight o’clock. I was quite clear about the fact that once I left, my house would stand empty for probably the first time since the day it was built. It was a strange feeling and perhaps explains why I was leaving so late, walking around the house many times over, checking one last time to see that all was in order.

    It is hard to explain my feelings once I did finally set off. As I drove further and further from the house, I found the surroundings grow unrecognizable. I began to have a feeling of unease mixed with excitement. I took a turning and found myself on a road circling the edge of a hill. I could sense the steep(陡峭的) drop to my left. I felt a sense of alarm that I was perhaps not on the correct road at all, but speeding off in the wrong direction into a wilderness. It was only the feeling of a moment, but it caused me to slow down. And even when I was sure I was on the right road, I felt forced to stop the car a moment to think carefully.

    I decided to step out and stretch(伸展) my legs a little. On the one side of the road, thickets and small trees rose sharply, while on the other I could now see the distant countryside and a town nearby.

    I walked a little way along the roadside, when I heard a voice behind me. Until this point I had believed myself quite alone and I turned in some surprise. Sitting on the large stone was a thin, white-haired man. He called to me again and signaled me to join him. For a moment, I took him for a homeless man, but then I saw he was just some local man enjoying the fresh air and summer sunshine, and saw no reason not to do so.

12、Why did the author set off later than planned?

A. Because he repeatedly checked the house.

B. Because he was feeling sad about leaving the house.

C. Because packing his belongings took longer than expected.

D. Because there was no one to help him get everything ready.

13、What caused the author to start driving more slowly?

A. The road had become steep.

B. He realized he was driving too fast.

C. The beautiful scenery attracted him.

D. He suddenly feared that he might get lost.

14、When the author walked out of his car, he ________.

A. didn’t expect to see anyone

B. didn’t want to speak to anybody

C. didn’t know there was a town nearby

D. couldn’t see anything because of the tree

15、What was the author’s attitude to his trip?

A. He just wanted to finish it. B. He felt unable to continue it.

C. He regretted having started it. D. He had mixed feelings about it.

二、七选五

16、How to be a more responsible person?

16、答案：DBCFE

解析：①上文“However, you can hear and see a lot of different things, both good and bad.”(然而，你会看到和听到各种各样的好的或坏的事情。)提到我们会了解到许多不同的事情，好的、坏的都有，D项“你的言行由你自己选择”承接上文，是下文“your sense of responsibility depends only on you”(你的责任感只取决于你)的原因，为下文“That”所指代。故选D项。

②分析文章结构可知，设空处是第二段的主旨句，是增强责任感的方法一。由下文“If you make a mistake, admit it. Instead of making excuses, give the true reason why you failed.”(你犯错了就得承认。不要找借口，而是指出你失败的真正原因。)可知，该段主要讲的增强责任感的方法是“不要为自己找借口”，B项符合题意。故选B项。

③上文“By always complaining about the world around you, you actually fill yourself with negativity.”(其实，如果一直抱怨你周围的世界，你内心就会充满消极。)讲的是抱怨会让你变得十分消极，C项“消极会让你十分痛苦”进一步阐述了由抱怨产生的消极所带来的后果，与下文“所以，停止抱怨！”形成因果关系，所以C项符合题意。故选C项。

④上文“You’re responsible for your own future, so stop delaying now and start taking action on what truly matters.”(你要对自己的未来负责，所以现在别再耽误下去了，要对真正重要的事物展开行动。)讲的是不要再耽误时间，F项“你所浪费的时间本可以花在更好的事情上的”则进一步指出耽误的后果，从而说明为什么不要耽误时间，而要开始行动，所以F项符合题意。故选F项。

⑤上文“Having a routine is good.”(生活规律是件好事。)讲的是生活规律很好，E项“这意味着有条理，也意味着你的生活处于正轨”则解释了为什么生活规律是件好事，符合题意。故选E项。

36、答案：resources

解析：考查名词。句意：人类应该充分利用有限的资源。形容词 limited后接名词形式。名词resource作为“资源”之意，为可数名词，前无冠词，泛指，所以用复数形式，根据汉语提示及句意，故填resources。

37、答案：regularly

42、答案：struggling

解析：考查非谓语动词。句意：当他看到一个小男孩在河里挣扎时，他脱下夹克跳进了水里。分析句子结构和意思可知，这里需要“挣扎”对应的动词struggle的现在分词形式，作宾补，struggle是被修饰的名词a little boy主动发出的动作，固定搭配see sb. doing，意为“看到某人正在做某事”。故填struggling。
