The only survivor of a shipwreck(失事船)was washed up on a small, uninhabited island. He prayed worriedly for God to rescue(营救)him, and every day he scanned the horizon for help, but {#blank#}1{#/blank#}seemed forthcoming(即将来临的). Exhausted, he {#blank#}2{#/blank#}(eventual)managed to build a little hut(小屋)out of driftwood(漂浮的木头)to protect him{#blank#}3{#/blank#}the bad weather, and to store his few possessions(财产). But then one day, after searching for food, he arrived home to find his little hut in flames, the smoke{#blank#}4{#/blank#}(roll)up to the sky. The worst had happened;{#blank#}5{#/blank#}was lost. He was almost fainted(昏倒)with grief and anger. “God, how could you do this on me!” he cried. Early the next day, however, he was awakened by the sound of a ship that {#blank#}6{#/blank#}(approach)the island. It had come to rescue him. “{#blank#}7{#/blank#}did you know I was here?” he asked one of his rescuers. “We saw your smoke signal,” they replied.

    It is easy to get discouraged when things are going bad. But we{#blank#}8{#/blank#}lose heart,{#blank#}9{#/blank#}God is at work in our lives, even in the middle of pain and suffering.

    Remember, next time your little hut is burning to the ground it just may be {#blank#}10{#/blank#}smoke signal from the grace(恩泽)of God. For all the negative things we have to say to ourselves. God has a positive answer for them.

    Whether enveloped by the thick smog from factories or unseen poisons from vehicle waste gases, many cities around the world are losing the battle against air pollution．

    Somewhere, many people died from breathing in the smoke and harmful gases {#blank#}1{#/blank#} (pour) into the air．In China and India, the damage of this poisonous air is particularly alarming, {#blank#}2{#/blank#}(cause) three million deaths in those two countries．As a result, some out-of-breath citizens are turning to bottled air．

    Many companies are compressing fresh countryside air into bottles and {#blank#}3{#/blank#} (sell) it online．It sounds like a joke but the idea is to raise {#blank#}4{#/blank#}(aware) and it provided people {#blank#}5{#/blank#}fresh air at a price．One such company is Vitality, {#blank#}6{#/blank#} collects air from the Canadian Rockies and compresses it into container．Vitality started the business to sell the canned air as joke gifts at first．{#blank#}7{#/blank#} the products took off in a {#blank#}8{#/blank#} ( surprise) way then．So, the manager came up with the business idea {#blank#}9{#/blank#} they can sell fresh air over the world．The manager of the company  has  made {#blank#}10{#/blank#}clear that China, India and South Korea have become its main markets．

    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?

To any soldier

    I served as a second lieutenant (少尉) in a war thirty years ago. Married for only a year and a half, I missed my wife and baby daughter a lot. In the years before cell phones and Wi-Fi, we had limited opportunities {#blank#}1{#/blank#} (communicate) with loved ones.

    One night while sitting by myself, I investigated the "Any Soldier" mailbox, a cardboard box with letters and packages from Americans. I chose one shoebox-size package. Inside I found about 20 greeting cards {#blank#}2{#/blank#} children. At the bottom was a letter written by their teacher  {#blank#}3{#/blank#} (explain) how her kids had put the box together and how they supported our efforts in the war. Truly touched at that very moment by this gesture, I decided to write a letter of gratitude. I thanked the teacher for  {#blank#}4{#/blank#} her children had done—its impact on my patriotism, my morale, and, {#blank#}5{#/blank#} (significantly), my uplifted faith. For security reasons, I was able to sign only my name.

    Around 2013, I received a Facebook friend request from a woman with  {#blank#}6{#/blank#} I shared no contacts. I replied that  {#blank#}7{#/blank#} we were friends, I could not accept her request. She responded with one question: "Are you Second Lieutenant Bartholomew?" I replied that I had been at one time.

    "Dear sir," she wrote. "We have never met, but thirty years ago I was a second-grade teacher at a school in Ohio and our classroom sent a care package  {#blank#}8{#/blank#} (address) to Any Service Member.' The thank-you letter you composed was framed and it  {#blank#}9{#/blank#} (post) on the wall of the school for more than 20 years. I wanted to again thank you for your service to our country."

    We never spoke again, but this gracious teacher strengthened my belief in doing what my mother always taught me: Write thank-you notes— {#blank#}10{#/blank#} never know how many people your kindness can touch.
