A
Swimming Holes in America
In America, these secret swimming holes are hidden and hard to reach but well worth the adventure.
Cummins Falls
Looking for the best place to escape the summer heat in the heartland of America? For more than 100 years, Cummins Falls, a scenic,75-foot waterfall located in Jackson County, TN, has been a treasure for Tennessee natives. But now, the secret is out! Although it’s a bit tough to get to, once in the park, the mountains and river provide unmatched beauty on your way to taking a swim in Tennessee's eighth-largest waterfall.
Sliding Rock
A popular place to cool off during those hot North Carolina summers, Sliding Rock waterfall is located in the Pisgah National Forest in Transylvania County. A flattened rock about 60 feet lies in a nearly 7-foot-deep pool at the bottom, making this natural waterslide a great place to visit with people of all ages.
Mooney Falls
It is the tallest water feature in the Grand Canyon, rising 190 feet above the surface. Named after an explorer in the 1800s, Mooney Falls is accessible only by crawling（爬）through 2 underground passages and then climbing down a sheer cliff（峭壁）face with just a couple of chains to hold on to. Although it is tough to get to, the view and the cool alone make it worth the trip.
Lihue Estate
A private swimming hole at the old Lihue Sugar Farm on Kauai, HI, was changed into an inner-tube water ride by Kauai Backcountry Adventures in 2003 and opened to adults. The waters for this 2.5-mile journey, which come from near the top of Mount Waialeale—one of the wettest spots in the world—are channeled through ditches（沟渠）that were hand-dug by farm workers over a century ago.
1. Which hole may be the favourable destination for families?

C. Mooney Falls.
D. Cummins Falls.
2. What can we learn about Mooney Falls from the text?
A. It wasfound by an explorer.
B. It was hand-dug in the 1800s.
C. It is dangerous to arrive there.
D. It is the tallest fall in the world.
3. What is special about Lihue Estate?
A. It is man-made.
B. It is a private area.
C. Its water is from underground.
D. It lies on the top of Mount Waialeale
B
Japan is known to have higher than average rates of stomach cancer. Recently, the town of Kaneyama in Yamagata Prefecture decided to get its 6, 000 residents (居民) tested.
However, the frozen urine samples (尿样) are not tested in conventional ways. Instead, Professor Masao Miyashita and his team are using them in a trial to determine if specially trained cancer-sniffing dogs can accurately detect the disease. Though the study is still in its early stages, Miyashita is thrilled with the results. He said, “In our research so far, cancer detection dogs have been able to find signs of cancer with an accuracy of nearly 100 percent.”
Researchers have known about the animals’ superior sensory skills for decades. However, their ability to detect cancer in humans came to light in 1989, after a dog sniffed out early-stage malignant melanoma (恶性黑色素瘤) on a patient’s leg in London. Since then, scientists from many countries have conducted studies to test dogs’ great skill at identifying cancer chemicals.
While most dogs can be trained for the task researchers say the best candidates are dogs that are precise, quiet, and perhaps even a little shy. The training process is similar to how dogs are taught to learn any trick — by rewarding them with treats! However, it takes much longer because the dogs have to learn to separate the “cancer scent (气味)”from the thousands of organic compounds (有机化合物) in the human body. Researchers begin by exposing the dogs to urine samples from people with cancer, people with other diseases, and patients with no health issues, Once the dogs are able to accurately identify cancer, they are further trained to detect particular kinds of cancer.
Successful as they may be, experts think dogs are unlikely to replace conventional tests. For one, it takes about seven years and costs as much as $45,000 to train a single dog. Klaus Hackner, a researcher and physician who studies dogs detecting cancer in breath samples at Krems University Hospital in Austria, is also not convinced dogs can be relied upon alone. Patients, therefore, have to receive further tests to confirm if they have the disease.
4. What do we know about the cancer-sniffing dogs mentioned in Paragraph 2?
A. They have done a great job.
B. They are trained in a special way.
C. They can easily learn to distinguish cancer.
D. They can be seen in many Japanese hospitals.
5. What does the author intend to do in Paragraph 3?
A. Offer readers some advice.
B. Add some background information.
C. Summarize the previous paragraphs.
D. Introduce a new topic for discussion.
6. What kind of dog is suitable for the cancer-sniffing job?
A. Smart and brave.
B. Active and faithful.
C. Strong and patient.
D. Careful and peaceful.
7. What is Klaus Hackner’s opinion on cancer-sniffing dogs?
A. They should work as a team.
B. They need to receive more training.
C. They can replace doctors in detecting cancer.
D. They should be used together with traditional tests.
C
Following the Famous Silk Roads
The Silk Roads were a networkof ancient trade routes that extended from East Asia all the way to theMediterranean. A key section of the Silk Roads is the Chang’an-Tianshan corridor（走廊）, whichstretchesover a distance of around 5,000 kilometres through China, Kazakhstan and Kyrgyzstan, covering a total of 8,700 kilometres of trade routes. The three countries jointly pursued an application for UNESCO World Heritage (遗产) status which contained detailed research on the 33 sites along the corridor. This made history as the first successful multinational World Heritage application.
The starting point of the corridor and the entire Silk Roads network isXi’an, inShanxiProvince. Further west on the Silk Roads, the geography gradually changes from wild deserts to high, snow-capped mountains to vast grasslands as the routes pass through theTianshanMountainsand emerge in the valleys ofCentral Asia. Although the Chang’an-Tianshan corridor of the Silk Roads ends here, the network continues westwards until it reaches theMediterranean.
The corridor began to develop in the 2nd century. Assigned by the emperor, the ambassador Zhang Qian
journeyed from Chang’an toCentral Asia, seeking to build bridges between the Han Dynasty and the Western Regions. Following Zhang’s efforts, trade routes took shape and relationships were strengthened between the major powers of the time, with the routes network reaching as far as theRoman Empire.
Economic activities along the routes network were not limited to trade in silk. They contributed many other items to the marketplace of goods. The routes were busy with camels carrying loads of goods and businessmen selling everything imaginable.China’s exports included silk, porcelain, ironware and tea, while horses, jewellery, spices and grapes were all imported over vast distances from the West.
In addition to trade exchange, the network served as a bridge for cultural exchange which shaped the evolution of science, art, technology and many other areas in societies along the network. Astronomy and mathematics were introduced toChinafromIndiaandArabia; important Chinese inventions such as papermaking and printing were brought to the West.
All of these activities contributed to a great age of expansion as trade and cultural exchanges gave people access to new goods,knowledge and ideas. These routes connected Eastern and Western civilizations, which achieved a shared development. The addition of the Chang’an-Tianshan corridor to the UNESCO World Heritage List is a milestone in recognition of the Silk Roads as a crucial part of humanity’s common heritage.
8. The key section of the Silk Roads is________.
A. the Mediterranean
B. Xi’an, inShanxiProvince
C.KazakhstanandKyrgyzstan
D. the Chang’an-Tianshan corridor
9. The underlined word “stretches” in Paragraph 1 is close in meaning to________.
A. stands
B. spreads
C. moves
D. flies
10. Zhang Qian travelled from Chang’an toCentral Asiato________.
A. export silk, porcelain, ironware and tea
B. purchase horses, jewellery, spices and grapes
C. seek help from the most powerful western countries
D. build bridges between his country and other countries
11. What was the role of the Silk Roads according to the passage?
A. It helped to change the wild deserts to grasslands.
B. It was recognized by the UNESCO asChina’s heritage.
C. It speeded up the development of the countries involved.
D. It started a trade competition between countries along the way.
D
To hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.
As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.
Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend to congratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.
Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higher when I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.
So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”
Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarely takes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots of friends.
12. What is most people’s attitude towards online friendship?
A. Negative.
B. Positive.
C. Objective.
D. Neutral.
13. Why does the writer share her own experience in paragraph 2?
A. To introduce the background information of the text.
B. To convey the writer’s attitude and give the related example.
C. To prove the likely risk for people to develop friendship online.
D. To remind people of the various benefits of making friends online.
14. How can online and offline friendships be deepened?
A. They should be based on shared interest.
B. They need to have common ground.
C. They require support from each other.
D. They can’t live without social media.
15. According to the author, what’s the golden rule to make friends online?
A. A friend to all is a friend to none.
B. Without confidence there is no friendship.
C. A friend without faults will never be found.
D. Friendship cannot stand always on one side.

52.阅读下面短文，根据其内容写一篇60词左右的内容概要。

Effective communication can make you an effective leader and success can come much more easily. It is very important to be a confident and efficient communicator so that others can understand you. However, in order to become an effective communicator, you need to be an effective listener first.
To be a good listener, you need effective listening skills, which will help you.
Understand other peoples' point of view. However, most people generally overlook the skill of listening. Actually, communication is never a complete process if you are only a good speaker without being a good listener. You may be very good at expressing your thoughts effectively. But if you are not good at understanding other people's point of view, it will never be considered effective communication.
Usually, speaking is considered an active process and listening is claimed to be a passive process. Listening, however, is undoubtedly an active process, too. It doesn't just mean sitting in front of someone and staring at their eyes. In order to understand someone better, you need to analyze their thoughts and words. Additionally, you need to show that you are listening. For instance, you can say "I see," "go on" or just nod your head. Of course, in the case of disagreement, you do not necessarily have to do that. You can also ask questions if you have problems understanding that person's perspective. Asking questions will not only improve your listening habits but also make the other person realize that they are being heard.
Too often, we attach great importance to the skill of speaking; however, most of us do not value the skill of listening very highly. Now is the time for you to break the old stereotype（刻板印象）and follow the new trend,
which is a contributing factor to effective communication.
