I discovered that inside the-wonderful box lived an amazing person whose name was Information Please. There was nothing she did not know.

    One day my mother went out. I accidentally hurt my finger when I was playing with a hammer. I walked around the house sucking my finger, finally seeing the telephone. Quickly I dragged a chair over and climbed up.

    “Information Please, ”I spoke into the receiver. A click or two and a small clear voice spoke into my ear. “Information.”

    “I hurt my finger…”I cried into the phone.

    “Isn't your mother home?” came the question.

    “Nobody's home but me.” I sobbed.

    “Are you bleeding?” the voice asked.

    “No,” I replied, “I hit my finger with the hammer and it hurts.”

    “Can you open your icebox?” she asked. I said I could.

    “Then take a little piece of ice and hold it to your finger.” said the voice.

    After that, I called “Information Please” for everything. I asked her for help with my geography and she told me where Philadelphia was. She helped me with my math. She told me her name was Sally.

    Then, there was the time my pet canary（金丝雀）died. I called “Information Please” and told Sally the sad story. “Why is it that birds sing so beautifully and bring joy to all families, only to end up as a pile of feathers?” She listened, then said quietly, “Paul, always remember that there are other worlds to sing in.” Somehow, I felt better.

    One day when I called “Information Please” again, a different voice answered “Information.”

    I asked for Sally. “Are you a friend?” she said.

    “Yes,” I answered.

    “I'm sorry to have to tell you this,” she said. “She died five days ago.” Before I could hang up she said, “Wait a minute. Did you say your name was Paul?”

    “Yes.”

    “Well, Sally left a message for you. The note said, ‘Tell him I still say there are other worlds to sing in. He'll know what I mean.'” I thanked her and hung up. I knew what Sally meant.

    You can love them or hate them, but no matter which tourist destination you visit, chances are you'll see someone with their head buried in a Lonely Planet guidebook.

    Lonely Planet is one of the world's largest travel guide brands, publishing more than 500 different guides in eight languages. The popular brand also produces television shows, websites and podcasts (播客) all devoted to travel.

     Some people praise Lonely Planet books because they make traveling easy and affordable. They also save time and make sure you don't miss the best things.

    They also provide the reviews of hostels, hotels, restaurants and ticket information about your destination.

    This can be great if you're a nervous traveler, or if you haven't traveled by yourself before. If you're in a country where you don't speak the language, sometimes there's nothing better than getting into a taxi and opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that's cheap and clean, with friendly staff and cold beer.

    But others criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take the fun and spontaneity (自发性) out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen. They also regret that if you follow a guidebook, you'll end up doing the same thing and having the same experience as everyone else. You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.

    Another criticism of travel guides is that they have a large impact on local communities. For example, some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and, in 1981, the first woman to join the U.S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” said Parks.

    It is common to see many different kinds of insects while spending time outside in the summer. Some of them do not trouble people and can even add beauty to the natural environment. Other insects can harm the environment or humans. The population of these insects seems to stay large and healthy.

    But scientists say this does not appear to be true for some flying insects that serve an important purpose. There is growing evidence that these insects are decreasing across the world.

    One researcher looking into the present insect population is Doug Tallamy, a professor at the University of Delaware. He remembers walking through Washington D. C., in the past when it was "alive with insects, especially butterflies". Now, he said, "The flying insects are actually gone." Wilson said this point seemed to be proved during a drive he made last year from Boston to Vermont. He was surprised that, during his trip, he counted only one insect that had hit the car's front window. Several other scientists have carried out similar tests by checking how many insects hit their cars while traveling.

    While researchers admit this method is not scientific, they say it can still help them understand the changing flying insect population. There have not been many studies done on the flying insect populations covering large areas. However, some international research suggests a downward turn. In 2006, a group of studies showed that there had been a 14-percent drop in ladybugs(瓢虫) in the United States and Canada from 1987 to 2006. In Germany, a 2017 study found an 82-percent drop in the number of flying insects compared to levels recorded in 1990.

    After the German study, other countries also started looking into the problem. David Wagner of the University of Connecticut says other evidence leads him to believe the findings of the 2017 study are "clearly not a German thing".

    An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage.

    The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space.

    Millions of pieces of junk are turning around in orbit the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage.

    Various companies have plans to send thousands of new satellites into low-Earth orbit, already the most crowded area.

    The RemoveDEBRIS experiment is run by a company and researchers led by the U. K.'s Surrey Space Center and includes Airbus, Airbus-owned Surrey Satellite Technology Ltd. and France's ArianeGroup.

    Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large pieces of junk, including dead satellites up to 10 meters long.

    The RemoveDEBRIS satellite will conduct a few more experiments in the coming months, including testing navigation features that could help guide the satellite to a specific piece of debris.

Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the success of this week's experiment was exciting, but he cautioned against "over- publicizing" it.

    There are still enormous barriers to clear before operational cleanup tasks are underway, he said, and the most discouraging is figuring out how to fund such projects.

    Aglietti, the Surrey professor who helped lead the RemoveDEBRIS project, said "The challenge will lie in persuading the relevant authorities to sponsor these tasks." Aglietti said he hopes RemoveDEBRIS will conduct a few cleanup tasks per year, targeting the largest pieces of junk in the most crowded orbits.

Bing, also known as a Chinese pancake, is a traditional Chinese recipe, similar to pancakes. It is commonly made of dough (面团).  {#blank#}1{#/blank#}, be prepared to learn how to make these yummy recipes!

Step 1: Combine the ingredients

Combine the ingredients for the dough (flour, salt, and cooking oil). Knead (揉) the dough until it has a soft consistency that isn't too wet. During this time, you can adjust the consistency, for example, by adding more oil or flour.  {#blank#}2{#/blank#}. 

Step 2: Separate the dough

Separate the dough into different pieces, the size that you want.  {#blank#}3{#/blank#}, don't separate it too much, and vice versa. You can use a rolling pin to help with making a circle. Chinese Pancake is commonly made in a circle shape, but can be any shape you want!

Step 3: Add spring onions

Add spring onions to the dough.  {#blank#}4{#/blank#} and sprinkle them on the bing. This gives the flavor for the cong you bing. The name "cong" in cong you bing actually refers to the spring onions. These can also be called scallions, green onions, and onions. You can also knead the dough again to mix the onion in. 

Step 4: Fry both sides

Fry both sides of the pancake on low-medium heat until the sides are golden brown. It takes 3-5 minutes per side. Remember to take it out before the sides get dark brown. Fry for a short time if you want a soft pancake, and fry it for a longer time to make it crispier. 

Step 5: Serve and enjoy!

{#blank#}5{#/blank#}, but can be served in formal meals as well. 

A. Divide it into ten equal pieces

B. Cut the onions into tiny pieces

C. It can be eaten as a casual food

D. Make sure you have enough dough

E. If this is already mouthwatering to you

F. If you want to make the pancake bigger

G. Heat up the pan while still working on the dough
