1 . Two American astronauts were greeted by more than a dozen private boats on Sunday as their SpaceX capsule landed safely in the Gulf of Mexico. A few boats went for a closer look at the capsule, which, aided by parachutes, gently hit the water off the coast of Florida. As the capsule bounced in the water, a recovery team instructed the boaters to stay away.

This raised concerns among NASA and SpaceX officials about security and safety procedures. The NASA administrator, Jim, acknowledged that the unprotected reception should not have happened. "If there is an emergency, the boats might have made recovery efforts, but there were poisonous smokes from the capsule. We need to do better next time," he said.

The Coast Guard waned boaters to stay clear of the area in a radio broadcast two hours before the splashdown, but many boaters ignored the requests and decided to enter the area, putting themselves in potential danger.

Robert L. Behnken and Douglas G. Hurley, the NASA astronauts, returned to Earth after nearly 64 days in orbit, most of them spent aboard the International Space Station. Their trip home was aboard the Crew Dragon, built by the private company SpaceX to transport NASA astronauts. The agency has relied on Russia for trips to space since the space shuttles were retired in 2011.

While the shuttles, like airplanes, landed on runways, SpaceX chose water landings, which NASA has not done since 1975, when the last of the Apollo modules went to space.

2 . On a cold November morning in Y osemite National Park, on the south-west face of EL Capitan, Alex Honnold holds on to the side of the wall with nothing but the tips of his fingers and two thin edges of shoes, attempting to do something that professionals have long wanted to do--a“free solo” climb of the world's most terrifying cliff (悬崖). That means he is alone and climbing without a rope as he makes his way up more than half a mile of rock.

Paul Preuss, the father of the free soloing, stated the key of the climbing was to master a mountain with superior physical and mental skill, not “artificial aid". Having made some 150 ropeless climbs by the age of 27, he fell to his death in 1913 while free soloing in the Austrian Alps. But Preuss's ideas survived and inspired the “free climbing”movement of the 1960s, which supported using ropes and other safety equipment. The next free soloist appeared in 1973, when Henry Barber climbed up the 1,00--feet north face of Yosemite's Sentinel Rock without a rope. In 1976, John Bachar free soloed New Dimensions, a 300-foot cliff in Yosemite and Peter Croft free soloed two of Yosemite's most celebrated routes--- Astroman and Rostrum--in the same day.

Croft's achievement stood until 2007, when Honnold, then 22, astonished the world by repeating Croft's Astroman--Rostrum masterpiece and free soloed two famously tough routes in Zion National Park and Y osemite. Now, Honnold is attempting much higher goals and he is well on his way to completing the greatest rock climb in history.

3 . What can holidaymakers in Argentina do in the country? Express.co.uk spoke to the travel experts to find out more.

The best time to visit Argentina

If you want to avoid crowds and peak prices while still enjoying everything offered, Lloyd, Director of Sunvil Latin America, advises visiting from October to mid-December and April to mid-June.

If you want to see the Patagonia penguins (企鹅), Tom Bourlet, a travel blogger, advises going between October and March.

The best places to visit in Argentina

“Buenos Aires is a melting pot of cultures,” said Tom Hughes, “Here travellers will discover a wealth of culture, not to mention it is the birthplace of a fast dance, tango. Nature lovers should head to the world’s largest waterfall system, Iguazu Falls.”

“I highly recommend San Carlos de Bariloche,” Tom Bourlet said. “It’s a quite beautiful and fantastic, and also acts as a good base for exploring the Lake District.”

“The best holiday destination in Argentina is Patagonia. The most famous place is Ushuaia — the southernmost city in the world. Expect glaciers (冰川), national parks, wildlife and end of the world cruising,” said Lloyd.

The best accommodation in Argentina

Lloyd advises avoiding some of the chain hotels. “While it may be attractive to stay at famous hotels, I recommend some of the smaller boutique hotels in the city,” he said.

4 . 阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

In ancient times, our ancestors relied on stars to guide them       1    a clear night. Today,with the help of Beidou Navigation Satellite System (BDS),     2    is entirely built by Chinese engineers, we Chinese can easily find our way.

The BDS is one of four global navigation     3    (network),along with the United States' GPS,Russia's GLONASS and the European Union's Galileo. With the last satellite launched from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites     4    (complete) since then. On July 31,Beidou started providing full-scale global services. It's difficult to imagine the great effect which those satellites have on our daily lives. This year, Hellobike, a popular bike-sharing company came out with two new bike models     5    （equip) with the positioning service.Users can find shared bikes more accurately thanks to Beidou's global positioning accuracy of 2.34 meters.

As the     6    (large) space-based system in China,Beidou adopts a unique two-way communication system, including its ability     7    (receive) messages sent by people from areas with poor signals.     8     (obvious), this exclusive function isn't designed for users to chat online. Instead,it plays     9     important role when terrible disasters occur and ground-based communications are blocked. As Sun Jiadong,former chief designer of the BDS,put it:" The application of Beidou is only limited by     10    （imagine)."

5 . At some point when you were a child,a trusted adult likely told you that if you held a seashell up to your ear, you'd hear the ocean.    1    Seashells are not special capsules that have stored the sounds of their native homes.

But what exactly is that rushing sound you're hearing?    2     “The sound of an empty shell held up to the ear is created by echoes(回声）from sounds made in the environment.”Geerat J. Vermeil, a distinguished professor of Earth and Planetary Sciences at the University of California,told us.

    3    Other structures with openings, like empty bowls or bottles, can produce similar sounds. “When the noise around us hits the internal surface of this hard seashell, multiple reflection occurs,” said Vermeil. “Whether you hold a seashell or the mouth of an empty bowl around your ear, you experience the ocean-like sound quality as a result of a phenomenon called “resonance.”

    4     It says that you're hearing the sound of your own rushing blood in your body. But scientists also clarify that it doesn't change with variation of pulse or blood pressure. “All this is perhaps a bit unimportant, but a more interesting question is what controls the frequencies of echoes" Vermeil added,indicating that there's a need for further research into shape, volume and shell thickness in relation to pitch.     5     Actually, if you put a shell to your ear on the beach, the sounds you hear will include partly some ocean noises.

A．The same goes for shells.

B．The answer is less mystical.

C．This effect is not limited to shells.

D．Now you probably know that this is not true.

E．Scientists are working hard to find the answer.

F．Maybe the original myth is not completely false.

G．There's another explanation for the rushing sound in a seashell.

6 . While quite complicated at times, coding is a way of communicating with a machine ——in many ways similar to a human writing script and virtually anyone can learn it. It's made up of a set of rules and commands, and once you master them all, you can control a machine in any way you want!

Now, in the brave new world we live in, coding has become a new form of literacy, and the way of technology is progressing, understanding how machines work and how to "communicate" with them is going to be the new norm in future education.

So, what is coding in the first place? Responsible for bringing machines, websites, and applications to life, coding represents the act of issuing commands written in a programming language to achieve a specific result・ Most of everything you've seen on your desktop screen, a laptop or on an iPhone has been programmed by writing code sheets.

Why should kids learn how to code? On one hand, coding develops problem-solving skills. Writing code into a platform to make something "come to life" is a fairly high-precision craft. Through trial and error, a child will learn how to make something work and then even fix it if it fails along the way! On the other hand, coding gives them better job opportunities in the future. For all intents and purposes, programming is becoming increasingly popular and will be even more so in the future!

Learning how to code doesn't happen overnight. So, considering that the future has plenty of programming and technology for our children and us, having them get acquainted with this subject matters while they're still young. It is possibly the best way to give them an upper hand in education and find a well-paying job!

1. What is the key to learning how to code?

A．Being expert at communicating.	B．Mastering the rules and commands.
C．Possessing essential skills of writing.	D．Having interest in playing computer.

2. What is paragraph 3 mainly about?

A．Principles of coding.	B．Importance of coding.
C．Explanation of coding.	D．Devices that need coding.

3. What does the underlined part "upper hand” in paragraph 5 mean?

A．Advantage.

B．Pride.

C．Chance.

D．Permission.

4. What is the best title of this text?

A．Rules and Commands for Coding

B．Various Ways for Kids to Learn Coding

C．Benefits of Learning Coding at a Young Age

D．The Importance of Coding in Real Life

7 . The rapid growth in skyscrapers worldwide has led to a high demand for window washers since most of these buildings feature large glass panes (窗格) to highlight their breathtaking views.

Though the job offers a handsome salary, dangling alongside multi-story structures is dangerous, and accidents are not uncommon. However, if Israel-based company Skyline Technologieshas its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot.

"As a society, we've become too comfortable watching people hanging off the sides of 30-story buildings," says Yaron Schwarez, co-founder and CEO of Skyline Robotics. "No salary could justify allowing people to put their lives in the hands of a system of ropes."

Much like humans, Ozmo is placed on platforms suspended from the buildings and uses its arms and brushes to clean the dirt on the glass panes. A 3D map of the building's surface programmed into its system allows the robot to skillfully handle obstacles as it moves up and down the structure. Computer vision and touch sensors enable it to move out of the way in case of unexpected events, such as the sudden opening of a window.

Unlike current window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled water (蒸馏水) and a process called dirt absorption to do the job. Schwarez explains, "We use pure water to absorb and remove the salts, the minerals, the oils, and the dirt from the building. We are environmentally-friendly."

Ozmo is also expected to be much more efficient than humans. While it currently takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers. It will only make their jobs safer by lifting them to the role of supervisors, who will be remotely controlling the operation from below.

Whether Ozmo, which is still undergoing testing, does as good a job as human remains to be seen.

1. Which of the following can best replace the phrase "has its way" in paragraph 2?

A．Succeeds.	B．Hesitates.
C．Struggles.	D．Exists.

2. What can we learn about Ozmo from the passage?

A．It requires chemicals to clean.

B．It has trouble crossing obstacles.

C．It operates with great efficiency.

D．It works without human helpers.

3. What is the author's attitude towards the future application of Ozmo?

A．Optimistic.

B．Doubtful

C．Unconceded.

D．Objective.

4. What is the best title for the text?

A．Ozmo: a Double-edged Sword.

B．Ozmo: a Smart Window Cleaner.

C．Window Washing: a Dangerous Job.

D．Window Washing: a Blessing in Disguise.

9 . Mama and I spend mornings cleaning up the dirt that blows into our house. Mama says all the dust is due to the drought. The dirt sifts into everything. It covers our clothes. We have to wash the dishes before each meal. We rarely drive the truck because Papa fears the dust from the road will ruin the motor.

When my sister, Faye, and I walk to school, we wear kerchiefs over our mouths so we don’t breathe in the dirt. On days when the air is so bad that they close the school, we stay home and help Mama put wet sheets over the windows. But the dirt always finds a way in.

Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After lunch, Papa headed out to the field to check on the cattle while I played with Faye in the yard. The temperature suddenly dropped. I looked to the west and saw a huge black cloud of dust.

All the birds flew away. “I must warn Papa,” I thought to myself. To avoid her panicking, I gently told Faye to go back inside where she would be safe, and then headed off to the field.

The storm hit so fast, and in an instant the day turned into night. By the time I entered the cow field the fine sand was whipping across my face. I screamed for Papa, hoping my voice would lead him back.

The dirt and sand stung my skin like a thousand bees. Although I was terrified, I refused to turn back. My dad was stranded and needed my help. Covering my face with one hand, I groped my way toward the truck and opened the door. First I tried turning the truck’s lights on and off, hoping that Papa would see them flashing, but the sandstorm let no light escape. Then I pushed the horn again and again, so Papa would hear it. I pushed until I had no more strength in my arms.

Suddenly, Papa’s face appeared at the window. My heart leaped with surprise and relief. He opened the door and climbed onto the seat next to me. He then pulled me into his arms and said, “Oh, Iris, you saved me!”

Finally, the wind subsided and the dust began to settle. Dirt was piled up to the window on one side of the truck and halfway up the door on the other. Papa kicked against the door, opening it far enough to let us out.

Sand and soil drifts were everywhere, but we were safe.

10 . Not all bad emotions (情感) are necessarily bad. In fact, they can direct your behaviour in useful ways. If you’re stuck in traffic, anger with the situation might motivate you to find an alternative route (线路), which will then relieve your stress. But anger is less useful if you’re in the same situation, but stuck on a motorway with no option to alter directions.

Emotions have physiological effects, such as raising the level of cortisol in your bloodstream, which can affect your health. Indeed, a new study, published in Psychology and Aging, shows that high levels of anger are associated with poor health in older people.

The Canadian study did the study on 226 adults aged 59-93. They took blood samples to assess levels of chronic (慢性的) low-grade inflammation (炎症) and asked the participants to report any age-related chronic illnesses they might have. The participants also completed a short questionnaire about the level of anger or sadness they experienced in three typical days over a one-week period.

For the analysis, the researchers considered whether age could affect the results. They found that higher levels of anger were associated with inflammation and ill health in the oldest participants (aged 80 and above), but not the youngest ones (59-79 years). Sadness was not associated with inflammation or ill health in either age group.

The study is cross-sectional, meaning that it assessed a group of people at a single point in time. To get a fuller understanding of the relationship between bad emotions and health, we need studies that follow participants for a period of time — so-called prospective observation studies. Future studies should also take into account other factors that might relate, such as other emotions, stress and personality.

Although this new research shows a link between emotion and health in older age, we do not know whether anger causes inflammation and illness or whether health problems make people angrier.

A．Anger is the greatest danger to health.

B．The influence of anger on illness is unclear.

C．People in poor health are easy to get angry.

D．Evidence is needed to prove the effect of health.
