    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?

    Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and{#blank#}1{#/blank#}the first change would be the most powerful. Then we were off. As the rocket rose into the air, we{#blank#}2{#/blank#}(pull) back into our seats because we were trying to escape the pull of the earth's gravity. It was so {#blank#}3{#/blank#}(strength) that we could not say anything to each other. Gradually the weight lessened and I was able to talk to{#blank#}4{#/blank#}(he). "Why is the spaceship not falling back to the earth? On the earth if I fall from{#blank#}5{#/blank#}tree I will fall to the ground." I asked. "We are too far {#blank#}6{#/blank#} the earth now to feel its pull," he{#blank#}7{#/blank#}(explain), "so we feel as if no gravity at all. When we get  {#blank#}8{#/blank#} (close) to the moon little by little, we shall feel its gravity pulling us, but it will not be as powerful a pull as the earth's." I cheered up immediately and floated{#blank#}9{#/blank#}(weightless) around in our spaceship cabin {#blank#}10{#/blank#} (watch) the earth become smaller and the moon larger.

    The art of paper-cutting in China may date back to the second century, since paper {#blank#}1{#/blank#}(invent)by Cai Lun in the Eastern Han Dynasty in China. As paper became more affordable, paper-cutting became one of the most important {#blank#}2{#/blank#}(type) of Chinese folk art. Later, {#blank#}3{#/blank#}different regions using their own cultural styles, this art form spread to other parts of the world. {#blank#}4{#/blank#}(usual), the artworks are made of red paper, as red is connected with {#blank#}5{#/blank#}(happy)in Chinese culture, but other colors are also used.

    With {#blank#}6{#/blank#}(it)long history, paper-cutting, {#blank#}7{#/blank#}originated in China, has been very popular among the ordinary Chinese people. People put up papercuts on walls, windows and doors at wedding ceremonies or festivals {#blank#}8{#/blank#}(add)to the cheerful atmosphere(氛围).

    Chinese papercuts are rich in content. The auspicious(吉祥的)designs symbolize good luck and the avoidance of evil. The child, lotus(莲花)and bat designs suggest a family with {#blank#}9{#/blank#} large number of children and grandchildren. Birds, livestock, fruit, fish and worms are also familiar objects {#blank#}10{#/blank#}(accept) by Chinese farmers. In a word, papercuts used in different occasions have different meanings.

Chinese tea is good for cleaning our digestive system. From time {#blank#}1{#/blank#} time, we would like to have a cup of Chinese tea after {#blank#}2{#/blank#} meal. Sometimes, we use Chinese tea for cooking, especially tea eggs.

Tea eggs, a popular Chinese food, {#blank#}3{#/blank#} (sell) along the busy sidewalk or at a market food stand. It is not only a quick and delicious way to fill up your stomach, {#blank#}4{#/blank#} a unique way to learn Chinese culture of food.

Chinese tea eggs are easy to make. Simply prepare some {#blank#}5{#/blank#} (boil) eggs. Gently tap the egg shells with the back of a teaspoon and crack the shells. Next, {#blank#}6{#/blank#} (careful) place the cracked eggs in the pot with marinade (卤汁) and boil for about 15 minutes. Then let the eggs soak (浸泡) in the {#blank#}7{#/blank#} (mix) for about 4 hours, {#blank#}8{#/blank#} makes the eggs have enough flavor. The dark color of the marinade gives the egg a marbled effect. Before {#blank#}9{#/blank#} (serve), gently reheat the eggs with the marinade.

Although a tea egg comes from China and  {#blank#}10{#/blank#} (have) much to do with Chinese cuisine (烹饪), other similar recipes have been developed throughout Asia.
