    When young, I loved going on trail(小路) runs. It was my favorite way to escape stress. So, when I was back in my hometown after a tough first year of my Ph. D. program, I thought a trail run was just what I needed. But instead of helping me relax, the run did just the opposite.

    After I moved to the city for college, where my runs were on flat concrete paths instead of winding dirt trails, I used a GPS watch. When I went on trail runs again in the country, it constantly reminded me of the fact that I wasn't keeping up with my usual pace. I turned my watch off, thinking that would allow me to enjoy my surroundings and find the peace I expected, but I worried I was underperforming. "Why can't I let go and just enjoy myself?" I wondered. But after some introspection(反省), I realized why I was struggling­both on trail runs and in graduate school.

    Going into my Ph. D. , I had thought that my solid undergraduate track record would set me up for instant success. To my surprise, I was wrong. I lacked confidence in my research abilities which I thought stopped me performing well and I constantly felt my progress was too slow. Other students'self-confidence and their excellent results made me feel insecure. Finally, one day I broke down in tears in my adviser's office.

    Then came my visit home: I was having trouble because I hadn't properly adjusted my expectations to the differences between an urban run and a trail run.

    A Ph. D. is like a trail run: Sometimes you can run fast. Sometimes you might find yourself climbing up a steep, winding trail at a snail's pace. And that's OK. Barriers are unavoidable, and success looks and feels different on a challenging trail than it does on a smooth, flat path. Sometimes it's best to take a deep breath and do your best to meet the challenge.

    One of the most expensive parts of flying is the cost of gas, not to mention the environmental effect it brings. An Israeli startup called Eviation Aircraft hopes to solve the problems. They displayed the world's first all-electric passenger airplane this week at the Paris Air Show.

    The lightweight plane­playfully called Alice­will be able to fly about 600 miles between charges. So it will focus on transportation between cities. It seats nine passengers and two crew members. A typical flight should cost a customer about $200.

    "The fact that we' re building an electric plane from scratch instead of just refitting an existing plane with a battery means that we can design our aircraft to be more effective and efficient than present planes," said Eviation co-founder Omer Bar Yohay. He predicts that per seat, per mile, the cost would be equal to that of a taxi or train.

    The demand for electrically powered aircraft is projected to reach hundreds of planes per year within the next decade. The change from gas to electric in power is expected to save millions of dollars in fuel costs, not to mention the environmental benefits including significant reduction of air pollution and noise levels.

    When it comes to the new possibilities, Yosef Abramowitz, an energy industry expert, said, "In modern life, it is important to fight climate change and now we have a path to do so in flying." Abramowitz, a tireless advocate for solar power, added, "The batteries will hopefully be charged with solar energy too."

    To help further save fuel costs, the designers have also invented a "taxibot" that drags planes from the passenger gate to the runway, so the planes needn't run their engines.

    After appearing at the Paris Air Show, the Alice will travel to the U.S. for further tests. It is expected that the first commercial flights will take off in 2022.

    "I think for the first time in a very, very long time, we can look at flight again and talk about the next revolution," Bar Yohay said.

    We tend to think of our dreams as being uniquely personal­nighttime stories built from our own experiences that help us process our day-to-day lives. While dreams can give us a look into our personal selves, scientists have collected data that suggests dreams make their way into our cultural fabric(结构), showing themselves in ways that shape beliefs and expose collective anxieties.

    Roger Ivar Lohmann of Trent University conducted research with the Asabano people of the rainforest of Papua New Guinea, a unique group who didn't have outside contact until 1963. His studies looked at how dreams shape their beliefs and actions.

    According to Lohmann's research, dreams act as a sort of motivator or determinant of Asabano behavior. For instance, a dream may affect the way a person hunts or goes about treating medical conditions. The way dreams determine behavior is due to what Lohmann calls the "night residue" effect. This means that specific memories of dreams can affect the way a person acts when awake and inform their belief system.

    Dreams also seem to have an effect on the way many define themselves within their own cultures, and how sometimes reaching a distinct definition can cause anxiety.

    Matt Newsom of Washington State University spoke with college students in Berlin, and found many students had dreams surrounding conflicting views about their own identities(身份) in relation to what they saw as a return of German nationalism, which is a sensitive subject especially when we think of German identity as it's defined even many years after World War Ⅱ.

    Many students had dreams that centered around anxieties like "Where do I belong?" Many students never talked with one another about identity struggles in their dreams, yet many reported having such dreams. Newsom noted that dreams can be helpful "for identifying (识别) unspoken social and historical anxieties present in a given society."

    All of this research suggests that dreams can do more than help explain the thought of a person; we can learn about entire cultures and collective attitudes as well.

How to Grow Organic Tomatoes in a Container

    Anyone who has seen tomatoes growing in a garden knows that they tend to be huge plants.  So the first thing to do when considering growing tomatoes in a pot is to find a suitable variety.

    After you find the perfect plant, it is time to plant it. In general, plastic or fiberglass pots are best for growing tomatoes. They don't dry out quickly. While tomatoes love heat, they don't like being dry.  Besides, tomatoes need to grow in a reasonably large pot. A pot must be 8 inches deep. That's the absolute minimum. A 12- or 16-inch pot is even better.

    Any good quality organic potting soil works for tomatoes. Don't use soil dug directly from the garden.  Compost-based soil, whether purchased or mixed from your special recipe, is nice. When planting the tomato, put some soil in the bottom of the pot and set the plant in. After you have the plant set at the proper level, fill in around it with soil. The soil should go up to about an inch below the rim of the pot to allow room for watering.

     The best way to tell when to water is to stick your finger into the soil­if the first two inches are dry, it's time to water.

    The trickiest thing about growing tomatoes in a pot is that they are heavy feeders. Every time you water, you wash nutrients out of the soil. So fertilize (施肥) regularly. Once a month is good. But every other week, applying the fertilizer at half-strength is better.

A. It is too heavy for container gardens.

B. That's why clay pots are popular.

C. Instead, use whatever soil you can get.

D. And dry soil can reduce fruit production.

E. This provides constant nutrients for the tomato plants.

F. They require people's much work to stay manageable.

G. Tomatoes don't like being dry, so water them regularly.

    Nearly seven years ago, I hitchhiked (搭顺风车) across Canada. It was an exciting experience, which allowed me to look into the 1 of humanity.

    Once, I was dropped off in front of a(n)2 woman, who had pulled over because her  3 had broken down. I approached to make sure she was 4. She assured me she was fine and that her husband was on his way with a truck. So I went back to my 5, standing about 150 metres away. Her husband arrived. And 6 they had picked up the broken-down car, the old couple 7 to bring me back to their place for lunch. I 8 agreed.

    But our 9 was very funny. I could not­for the life of me­figure out what her husband was 10. He spoke English, but his strong accent made it 11 to understand. Every time he spoke to me, I'd have to 12, "I'm sorry, but what did you say?" And every time I said this, his wife would 13: "He saaaaaaid..." and then 14 her husband's words. But we had a good time together.

    This old couple's random 15 was just what I enjoyed about hitchhiking. You have non-stop social interactions(互动) that are authentic but only in a 16 time. A person becomes an important part of your life for an hour or two and then they 17. However, the beauty of these 18 being so kind never gets old.

    Each meeting I had was 19 into my little treasury (宝库) of memories that has begun to 20 with time. But together, they paint a broader picture of harmony in this country.

    Household garbage sorting and recycling has become a hot topic in Shanghai because of China's first compulsive garbage-separation law  every household and institution shall classify waste into four (category). Those who fail to sort garbage may (fine) up to 200 yuan.

    Previously, everything went into one bin, so this change has made many people very   (worry), who said they were struggling to master the details quickly.

    Now thanks to the efforts of  number of young programmers, discovering the proper classification for each piece of household waste has become as simple as taking a photo  calling someone using your smartphone.

    They have applied speech and image recognition technologies  apps and other smartphone services to guide Shanghai residents through the garbage-separation rules.

    Most of the apps and services, which  (begin) springing up last month in app stores, on messaging tool WeChat and mobile payment service Alipay, allow users to type in the name of waste (identify) which category it belongs to. Many apps also use speech and image recognition to make the process much easier, but their creators say they will disappear in time with the Chinese (become) more accustomed to the rules.

    It was Sunday yesterday. I didn't need go to school. So together with my friend, I went on a picnic. Carrying a bag of food, we set it out. The sky was blue but the air was fresh to breathe. We were very excited. All of the sudden, I felt my bike became very heavy. I realize there must have been something wrong with it. Sure enough, one of the tires got flatter. I had no choice but to walk. However, with two friends around me, I didn't feel disappointed. Late, a truck driver volunteered to get my bike repair. I was really lucky to meet such kind a man.
