1 . As a beginner of distance running, you probably have a million questions racing through your mind on performance, training, joining events, and generally looking good, right?    1    

How often should I run?

This would depend on your age, if you have had any injuries, your lifestyle, available time for running, and your goal.    2    Keep in mind that you want to enjoy every run instead of burn out quickly. If you have no physical problems, you should consider starting your running twice weekly. And gradually you can build up to 3 runs a week but only after 2 months' training. In between, you can try gym work-outs, cycling, swimming, etc.

    3    

Even though you don't move your arms or the rest of your body as much as you do your legs and knees, it is possible that the pain is coming from muscles not used to being exercised. Knee pain is very common but most beginners do not get runner's knee immediately.    4    

What should I eat?

Before your run, try to focus on the "Go foods", avoiding the ones with too much sugar. These are foods that are high on carbohydrates（碳水化合物）like bread, cereal, pasta, pizza, banana, and potatoes, among others. The best time to go carb-heavy is the night before the run and then 2 hours before going out for a run.

After your run, try to stick to small snacks like an energy bar, lean protein, and water to make up for what you've burned.    5    Do experiment and find a diet that suits you best.

A．Why is my whole body aching?

B．Different styles and distances require different skills

C．Many beginners start eagerly and try running as often as possible.

D．The answers to the most commonly asked questions are here for you.

E．The clothes should not be too tight and the shoes should fit perfectly.

F．However, what may work for one runner may not always work for you.

G．It usually happens after wearing the wrong shoes, or overrunning on a hard surface.

2 . You're at your favorite sporting event, watching your team play their hardest. Then all of a sudden you hear a cheer. This really seems to get the crowd fired up. But does anyone ever stop and think about how much time and effort it takes to be a cheerleader? Do you ever wonder how much sweat and practice go into cheerleaders being out there to cheer on their home team? Do you ever think these cheerleaders really have to have a good memory? Not only are they athletes, but they are smart athletes, and the nicest people you will ever meet. Cheerleading is a sport because cheerleaders take part in all kinds of competitions, and there is danger involved（卷入）.

It is not a well-known fact that cheerleaders have to compete in a lot of different competitions. This is something a lot of people think is very easy, but in fact, taking part in the competitions is one of the hardest things that cheerleaders have to do. Competitions take a lot of time and effort. I have been to 37 different cheerleading competitions since the age of five. And in my opinion, competitions require quite a lot of physical and mental effort.

Moreover, there are many dangerous activities involved. Jump is one of the most dangerous things in cheerleading. If you were to come down from the jump incorrectly, you could break a foot, or even a leg. Tumbling（翻腾动作）is another highly risky thing. During tumbling, concussions（脑震荡）may happen when you hit the head on the floor.

I believe that cheerleading is a sport because cheerleaders compete in all kinds of competitions, there are many different skills learn and master, and it can be a very dangerous sport. So the next time you are at your favorite sporting event listening to the cheers of the crowd, think about the preparation involved in this energetic sport.

4 . A little mouse, who had never seen anything of the world outside, almost came to grief the very first time he went out for an adventure. And this is the story he told his mother about his adventure.

"I was walking along peacefully, when, just as I turned the corner into the next yard, I caught sight of two strange creatures. One of them had a very kind look, but the other was the most fearful monster you can imagine. On top of his head and in front of his neck hung pieces of raw red meat. He wandered about restlessly, tearing up the ground with his toes and beating his arms fiercely against the sides. The instant he spotted me he opened his pointed mouth as if to swallow me, and then he let out a deafening roar that terrified me almost to death."

Can you imagine who it was that our little mouse was trying to describe to his mother? It was nobody else but Barnyard Cock and the first one the little mouse had ever seen.

"If it hadn't been for that terrible monster," the little mouse went on, "I should have made the acquaintance（认识） of the pretty creature, who looked so good and gentle. He had thick, soft fur, a kind-looking face, and a look that was very modest, though his eyes were bright and shining. As he looked at me, he waved his fine long tail and smiled. I am sure he was just about to speak to me when the monster I have told you about let out a scream, and I ran for my life."

"My son," said the mother mouse convincingly, "That gentle creature you saw was none other than the Cat. Under his kindly appearance, he bears anger against us. The other that appeared threatening was none other than the Barnyard Cock who didn't intend to hurt you in the slightest. As for the Cat, he eats us. So be grateful, my child, that you escaped with your life."

5 . Luke Grenfell-Shaw has developed a rare form of cancer. It started as a pain in his shoulder and the tumor（肿瘤）spread to his lungs, making it stage four. The Oxford graduate was teaching English in Siberia when he suffered shoulder pain and consulted the school nurse. It was her reaction to a lump on his back that sent him back home to Bristol. "I was 24 years old. I had done an ultra-marathon," Luke said. "48 hours later, I was back in hospital in the UK." On 19 June 2018, doctors informed Luke that he had cancer.

"I had kind of worked out that it was cancer, but what kind of blew me away was the fact that it was stage four cancer," said Luke. "That day, I felt like my life was disintegrated. My life had been comfortable and conventional. I worked hard and got rewards in terms of education, jobs, things like that. That was all taken away." On the day of his diagnosis(诊断), Luke had one clear thought in his mind that he wanted to cycle around the world. It was something he had always hoped to do, but the cancer news made him realize that he couldn't put it off.

"I realize that the future had to become now," Luke explained. He decided to cycle from Bristol to Beijing --- more than 5,000 miles --- on a tandem bike, because he wants to bring people along to share the experience with him. Luke will not only be joined by his family and friends for certain legs of his trip, but also by other young people who are living with cancer. "This trip is something I'm going to enjoy," said Luke. "It's bound to be the richest and most fulfilling experience that I can have."

3. Why did Luke decide to cycle around the world?

A．To realize his dream on the wheels.

B．To win the battle against his cancer.

C．To enjoy the rest of his life peacefully.

D．To draw worldwide attention to cancer.

6 . I experienced years of loneliness as a child. My older brother couldn't be bothered to play with me.

    1    Our interests were totally different. With no other kids of my age in the neighborhood, I had to spend hours by myself.

A bright spot for me turned out to be reading.    2    I loved the colorful photographs in the books. I started reading books on my own before age 5 and my mother took me to the public library once a week to borrow several books. I quickly graduated from typical children's books to ones with fewer pictures and longer chapters.     3     I wasn't alone any longer.

    4     I tried making toy cars with cardboard boxes and constructing buildings from leftover cardboard and bits of wood my father gave me. When my mother saw my creations, she told me how creative my designs were. Thus, I began my lifelong interest in making things. I Learned a lot about how to extend the life of objects and transform them into something new and useful. It was a trait（特 点）others found helpful, and I soon had friends who wanted to make things with me.

Another habit I formed early was being outdoors. My parents made it a point for their two kids to spend time outside, no matter the weather or season. My brother, of course, raced off to be with his friends, while I had plenty to do myself. There was making leaf houses in autumn, ice skating in winter, and so much more.     5    

A．Reading opened new worlds to me.

B．I enjoyed reading stories aloud.

C．I was invited to play with another kid.

D．My love of the written word began early as my mother read to me every evening.

E．They're all memories I treasure today.

F．My mother also encouraged me to make what I wanted.

G．His friends teased him about babysitting his sister.

7 . For many Americans, regular exercise is a complicated commitment—one made at the beginning of January that fades out within weeks or months. Busy work schedules, a lack of motivation and unease towards exercising in public all contribute to the discouraging statistics that only around a quarter of adults exercise enough per week.

This month, enterptiser Trent Ward and designer Yves Behar are uncovering their design for a mirror fitness system, Forme. Forme is reflective like a mirror, uses machine learning to heighten workouts, and offers attachments including ankle belts, rope handles and a heart rate monitor. When not in use, the two arms that form the resistance pulley (滑轮) system fold behind it and the display screen disappears, turning Forme into a simple full—length mirror.

Interest in home exercise has particularly increased recently around the world. Home workout apps have seen a significant uptick in downloads, and trendy brands like Peloton have rolled out free virtual workouts for everyone stuck indoors. One French athlete who was kept away from others chose to run an entire marathon on his 23-foot balcony.

But beyond the new restrictions affecting daily workout routines, Ward and Behar are tapping into the same concerns that have made every home workout appealing：the ability to save time and sweat in the privacy of one’s home. In an age of personal metrics (衡量标准)--where one can measure their heart rate and sleep cycles with smart watches and train for marathons with AI smart sneakers----Ward and Behar want to improve exercise through machine learning. Forme evaluates performance and adjusts weights accordingly. Easy access to one’s own performance data also makes it easier to track that progress and stay motivated.

Though it’s too soon to tell if mirror gyms will be the trend of the late 2010s to 2020s, Behar explained that having a screen in the home can become the basis for more than just fitness, such as shopping or telemedicine.

1. What does paragraph 2 mainly focus on?.

A．The ways to operate Forme.	B．The features of Forme.
C．The reasons to develop Forme.	D．The theory behind Forme.

2. How can Peloton benefit its users?

A．By offering them online workouts for free.

B．By raising their interest in marathon.

C．By keeping them far away from others.

D．By entertaining them with all kinds of downloads.

3. What makes home workout appealing according to paragraph 4?

A．The better results than outdoor activities.

B．The fresher air at home.

C．The privacy of home.

D．The convenient access to mass data.

4. What is the best title for the text?

A．Can Forme Have More Powerful Functions?

B．Does Regular Exercise Keep up with New Technology?

C．Is the New Trend of Smart Machines at Home available?

D．Is this AI—Powered "Mirror Gym" the Future of Home Exercise?

8 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security(安全) to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 10.42 Mbps. But by comparison, 5G promises gigabit(千兆) speeds.

“5G is one of those signs, along with artificial intelligence(人工智能)，of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle(车辆) is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have a large number of data coming from the vehicle itself, and a variety of sensors(传感器) are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane(车道). It could be weather information, but also connected infrastructure (基础设施)construction. There is lots of data behind that task, which is why we need high speeds.

Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting(打赌) that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable(显著的) because companies such as Apple are reportedly developing AR glasses to assist--or perhaps even replace--smartphones.

Ericsson stated at February' s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components(部件), the glasses could rely on hardware for processing(处理)power.

But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction, so 5G isn’t concentrated(集中) only in big cities.

1. What does the author want to stress in Paragraph 1?

A．The lightning- fast speeds of 5G.	B．The expectation of 5G world.
C．The difference between 4G and 5G.	D．The internet-connected devices in our life.

2. What does the underlined word “emblem” in Paragraph 2 mean?

A．Exhibition.

B．Success.

C．Symbol.

D．Explanation.

3. What will the author probably tell us next?

A．How to fully expand 5G coverage(覆盖范围).	B．Smart glasses will become faster and lighter.
C．Why 5G isn't concentrated in big cities.	D．The importance of infrastructure construction.

4. Where is this passage probably taken from?

A．A science fiction.	B．A science magazine.
C．A business report.	D．A film documentary.

10 . Insects rarely worry me. Mosquitoes annoy me, but only because I don’t like the unavoidable itching (痒) that follows. I don’t get spooked by spiders or terrified by white ants. Bedbugs (臭虫), though, are my big exception. I’ve never seen one, but I religiously check for them when I travel. And I’ve woken up from nightmares of them moving across my bed and up my legs.

While they aren’t disease carriers, a large number of bedbugs can eat away at your mental health as well as your pocketbook. Ultrasonic (超声波的) devices marketed to drive bedbugs away don’t have any effect. Bug bombs don’t work. Bedbugs are developing resistance to a common insecticide that once killed them. Even if the chemicals work, they can be dangerous for the humans exposed to them. High heat can be effective, but that’s not always a practical solution.

Some studies have indicated that cold might kill bedbugs after as little as one hour of exposure. But new research published in Journal of Economic Entomology finds that’s not the case. Cold can kill a bedbug, but only after days.

Joelle F. Olson and his colleagues froze bedbugs at various stages of life, fed and unfed, for varying lengths of time. The bad news was that the bugs didn’t die nearly as quickly as other studies had found. “In our study, bedbugs survived lower temperatures, with eggs surviving in short-term exposure to temperatures as low as -25℃,” the researchers write. But the bugs are not freeze-tolerant, the scientists found, and they can be killed—no matter what their stage of life or feeding status is. All it takes is 80 hours in temperatures of -16℃.

The finding confirms a standard practice for museum collections and food products: potentially infested (被寄生的) items are frozen to kill any hidden insect pests. And it provides a completely safe method of control for people, at least for items they can fit into the freezer.

1. What’s the meaning of the underlined word “spooked” ?

A．Frightened.	B．Interested.
C．Surprised.	D．Impressed.

2. What does the new research find?

A．Bedbug eggs are more tolerant of cold.

B．Low temperature is the key to killing bedbugs.

C．The level of cold bedbugs stand varies with age.

D．Bedbugs survive cold, but not for too many days.

3. In which aspect will Joelle’s finding make its contribution?

A．Improve the efficiency of freezers.

B．Overcome psychological fears of bugs.

C．Help people protect food from insect pests.

D．Find a standard practice for museum collections.
