Whenever I tell people that I teach English at the Berlin Zoo, I almost always get a questioning look. Behind it, the person is trying to figure out who exactly I teach…the animals?

Since June 2017, right before the     1     (arrive) of the two new pandas, Meng Meng and Jiao Qing, I have been helping the panda keepers at the zoo to feel more comfortable and     2     (confidence) speaking English. And who do they speak English     3    ?

Not the pandas, even though     4     language used for the medical training instructions is actually English. They talk to the flood of international tourists and to     5     (visit) Chinese zookeepers who often come to check on the pandas, which are on loan from China. They also need to be ready to give     6     (interview) in English with international journalists. This is     7     they need an English trainer.

So, what are they learning?     8     (basic), how to describe a panda’s life. It’s been an honor to watch the panda programme develop     9     to see the pandas settle into their new home. As a little girl, I     10     (wish) to be a zookeeper when I grew up. Now, I’m living out that dream indirectly by helping the panda keepers do their job in English.

2 . Yellowstone National Park offers a variety of ranger programs throughout the park, and throughout the year. The following are descriptions of the ranger programs this summer.

Junior Ranger Wildlife Olympics (June 5 to August 21)

Kids can test their skills and compare their abilities to the animals of Yellowstone. Stay for as little or as long as your plans allow. Meet in front of the Visitor Education Center.

Canyon Talks at Artist Point (June 9 to September 2)

From a classic viewpoint, enjoy Lower Falls, the Yellowstone River, and the breathtaking colors of the canyon (峡谷) while learning about the area’s natural and human history. Discover why artists and photographers continue to be drawn to this special place. Meet on the lower platform at Artist Point on the South Rim Drive for this short talk.

Photography Workshops (June 19 & July 10)

Enhance your photography skills — join Yellowstone’s park photographer for a hands-on program to inspire new and creative ways of enjoying the beauty and wonder of Yellowstone.

4 . According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them.

Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil.

“Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE)project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫).

Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms.

Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick.

6 . With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it’s comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible.

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.     1     But no matter when you travel, it’s a good idea to make your reservations at least 90 days in advance.

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.     2     Then you won’t have to walk through several cars on a moving train three times a day for your meals.

Bring a blanket. When you’re riding on trains, you won’t be provided with a blanket for free, even if your trip is an overnight one.     3     In the summer in particular, the air conditioning can make them quite cold.

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.     4     Note: The times listed on the schedules are departure times, not arrival times.

Have fun.     5     Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you’re going 67.92 mph.

Going to Mount Huangshan reminds me of the popular Beatles’ song “The Long and Winding Road”.     1     is so breathtaking about the experience is the out-of-this-world scenes. The rolling sea of clouds you see once you are at the top will remind you how tiny we     2     (human) are.

The hot spring at the foot of the mountain is something you must try after the climb. It will     3    (undoubted) help you get refreshed! The amazing thing about the spring is that the colder the temperature gets, the     4     (hot) the spring! Strange, isn’t it? But that’s how nature is — always leaving us     5     (astonish).

What comes next is the endless series of steps. You can’t help wondering how hard it     6     (be) for the people then to put all those rocks into place. Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure     7    offers a place where you can sit down to rest your     8     (ache) legs.

As the song goes, this long and winding road “will never disappear”, and it will always stick in the visitor’s memory. It sure does in     9     (I). While you’re in China, Mount Huangshan is     10     must to visit!

10 . Writing an essay is a difficult process for most people. However, the process can be made easier if you learn to practice three simple techniques.

    1     When you are first trying to think of ideas for an essay, put your pen to your paper and write nonstop for ten or fifteen minutes without letting your pen leave the paper. Stay loose and free.     2     Don’t worry about grammar or spelling. Even though this technique won’t work for everyone, it helps many people get a good store of ideas to draw on.

The next technique is to write your draft rapidly without worrying about being perfect.     3     Yet, by learning to live with imperfection, you will save yourself headaches and a wastepaper basket full of crumpled (弄皱) paper. Think of your first draft as a path cut out of the jungle—as part of an exploration, not as a complete highway.

The third technique is to try printing out a triple-spaced (三倍行距) copy to allow space for revision.     4     As a result, these writers never get in the habit of crossing out chunks (大块) of their draft and writing revisions in the blank space. After you have revised your draft until it is too messy to work from anymore, you can enter your changes into your word processor.     5     The resulting blank space invites you to revise.
