    I was wandering into the small store, when the store owner received a call from a customer. The customer and his wife had shopped there several months before. When noticing that his wife really liked one thing in the store, he wanted to buy it as a surprise. Because time was limited, out{#blank#}1{#/blank#} (go) the couple without buying it. It was not until several months later that the customer wanted to buy it.

    But the customer was in Tennessee, living far away from the store which was in Maine. What was more, he had been to the store several months before, and it was difficult to believe that the store owner would remember him, or  {#blank#}2{#/blank#} it was that he was referring to. There were{#blank#}3{#/blank#} (diversity) goods in the store. The customer's question was whether she could do it. She said yes. The store owner advised him to describe the thing for her and so he did.

    {#blank#}4{#/blank#} (inform) what the thing was like, the store owner took a few close-up photos with her camera« and e-mailed them to the customer. Having received the photos' then the customer decided which one was the very thing.

Then the customer said, “Now it is time we discussed a price over the phone.” Apart{#blank#}5{#/blank#}discussing the price, they also decided the time to send it. Then she took care of the credit card transaction (交易)online, and the customer proposed the gift{#blank#}6{#/blank#}(send) that afternoon. Then the agreement was reached. The customer said. “I live far away from your place now.{#blank#}7{#/blank#} I would get it myself.”

    The store owner was really smart. She wasn't necessarily{#blank#}8{#/blank#} (talent) for new technology but she was willing to push herself to find new ways to make the transaction (交易) actually happen. It was not a dramatic thing. It was the first time she had ever done it. Never before had she done such a thing.

    {#blank#}9{#/blank#} difficult it was, the store owner discovered a creative solution {#blank#}10{#/blank#} (contribute) to a new way of doing business. In my view, we should realize that challenge and opportunity go hand in hand.

People eat rice all over the world

    Rice is believed to have been first grown in China or possibly somewhere else in eastern Asia around 10,000 years ago. The earliest evidence of rice farming comes from a 7,000-year-old site near the lower Yangtze River village of Hemudu in Zhejiang province in China.

    Rice is a kind of food which requires much labor. In developed countries, the planting and harvesting is done {#blank#}1{#/blank#} (most) with machines.{#blank#}2{#/blank#}, in much of the world, these things are still largely done by hand. It takes one farmer 1,000 to 2,000 working hours {#blank#}3{#/blank#} (raise) a rice crop on 2.5 acres of land. The fact that rice {#blank#}4{#/blank#} (need) so much labor means {#blank#}5{#/blank#} (keep) a lot of the population on the land.

    Rice is also a crop{#blank#}6{#/blank#} need of lots of water. The wet rice {#blank#}7{#/blank#} (grow) in most of Asia needs hot weather after a period of rain and conditions provided by the Asian {#blank#}8{#/blank#} (rain) seasons affect many places {#blank#}9{#/blank#} rice is grown.

    Rice straws (稻杆) {#blank#}10{#/blank#} (leave)in the fields add nutrients (营养物) to the soil after rice is harvested. For the next crop, rice farmers can often enjoy a good harvest by adding little or no fertilizer (肥料).

    Just How Buggy is Your Phone?

    What item in your home crawls with the most germs? If you say {#blank#}1{#/blank#} toilet seat, you're wrong. Kitchen sponges top the list. But cell phones are pretty dirty too. They contain around 10 times as many germs as toilet seats. People touch their phones, laptops, and other digital devices all day long, yet rarely clean them.

    In one incident, a thief paid a terrible price for stealing a germy cell phone. He stole it from a hospital in Uganda during a widespread of the deadly disease Ebola. The phone's owner reported the theft before {#blank#}2{#/blank#}(die)from the disease. Soon, the thief began showing symptoms and finally {#blank#}3{#/blank#}(confess)to the crime.

    {#blank#}4{#/blank#} in that unusual case a cell phone carried dangerous bacteria, not all germs are bad. Most cause no harm. In fact, they could provide helpful information. Look at the surface of your phone carefully. Do you see some dirty mars? “That's all you,” says microbial ecologist Jarrad Hampton-Marcell. “That's biological information.”

    It turns out that the types of germs that you apply all over your phone or tablet are different from {#blank#}5{#/blank#} of your friends and family. They're like a fingerprint that could identify you. Some day in the future, investigators may use these microbial fingerprints to solve crimes. Phones and digital devices may be one of the best places to look for buggy clues.

    In a 2017 study, researchers sampled a range of surfaces in 22 participants' homes, {#blank#}6{#/blank#} countertops and floors to computer keyboards and mice. Then they tried to match the microbial fingerprints on each object to its owner. The office equipment was easiest to match to its owner. In an {#blank#}7{#/blank#}(early)study, a different group of researchers found that they could use microbial fingerprints to identify the person who {#blank#}8{#/blank#}(use)a computer keyboard even after the keyboard sat untouched for two weeks at room temperature.

    One day, microbial signatures might show {#blank#}9{#/blank#} people have gone and what they have touched. They could prove {#blank#}10{#/blank#} an unmarked device is yours. So, sure, your phone is pretty germy. Does that inspire you, or does it just bother you?

    Golden Gate Park is in San Francisco, California. It is one of the largest urban {#blank#}1{#/blank#}(park) in the United States. Over one million colorful flowers, trees and other plants grow in the park. But originally most of the park{#blank#}2{#/blank#}(cover) in sand. After a lot of work, it was finally built in 1870. Today, there are many people{#blank#}3{#/blank#}(visit) the park every day. They play basketball, soccer, golf and many other sports there. The park is closed in many places to traffic so people can walk, cycle, or skate{#blank#}4{#/blank#}(free).
