If the population of the Earth keeps on increasing at its present rate, there will eventually not be enough resources {#blank#}1{#/blank#} (leave) to support life on the planet. By the middle of the 26^th century, if present trends continue, we {#blank#}2{#/blank#}（use）up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on the earth will make{#blank#}3{#/blank#} necessary for us to look for open space somewhere else. But {#blank#}4{#/blank#} of the other planets in our solar system are capable of supporting life at present. One possible solution {#blank#}5{#/blank#} the problem, {#blank#}6{#/blank#}, has recently been suggested by an American scientist, Professor Carl Sagan. Sagan believes {#blank#}7{#/blank#} before the Earth's resources are {#blank#}8{#/blank#} (complete) exhausted it will be possible to change the atmosphere of Venus and therefore create a new world almost as large as the Earth {#blank#}9{#/blank#}.The difficulty is that Venus is much hotter than the Earth. {#blank#}10{#/blank#}, there is only a tiny amount of water there.

    I enjoy {#blank#}1{#/blank#} (climb) mountains whenever I can find the time to do so．Tom and Mike are my best friends，both of {#blank#}2{#/blank#} also like sports．Two years ago，the three of us {#blank#}3{#/blank#} (go) up to Mt．Lushan. Instead of taking a bus，which is {#blank#}4{#/blank#} (comfortable)，we preferred to climb．We started from the foot of the mountain early in the morning，{#blank#}5{#/blank#} (chat) all the way．After about one and a half {#blank#}6{#/blank#} (hour) climbing，we saw two mountain paths before us．We could not decide {#blank#}7{#/blank#} to choose．In the end，we took the right path，thinking that might be a short cut．But we were wrong．We could not find our way out， {#blank#}8{#/blank#} (lose) in the mountain．We had to use our hands and feet to make a way．We began to cry for help {#blank#}9{#/blank#} nobody answered．It was not until darkness {#blank#}10{#/blank#} (fall) that we found a right path leading up to a paved road．

    It was a dreadfully cold and cloudy afternoon. I was on the bus with my children, aged four and two, {#blank#}1{#/blank#}(head) home when it started to rain. I realized this would mean a wet walk home {#blank#}2{#/blank#} the bus stop.

    {#blank#}3{#/blank#} my house was only two blocks away, it was not a pleasant walk with one small boy asleep in the pram (手推婴儿车), the other one in a raincoat and no umbrella for myself. A pick-up truck passed us on the road. I tried to thumb a ride but failed. My little boy woke up with a start and began to cry. I {#blank#}4{#/blank#}(convince) that things might become worse and nobody would bother to help on such a terrible day. A few minutes later, {#blank#}5{#/blank#}truck drove by, but to my surprise, I saw it pulling back and the driver looking directly at us. A young man put the window down. “Hey, here's an umbrella for you, please take {#blank#}6{#/blank#}.” He called out. I stood there{#blank#}7{#/blank#}(astonish), barely believing that the man {#blank#}8{#/blank#}existence was unknown to me only moments ago, could be so{#blank#}9{#/blank#}(consider). “Come on, give this to your mummy,” he said to my older son. I accepted the offer and expressed my gratitude to him.

    This man might have needed the umbrella for himself later during the day but preferred to give it to me. It was a lesson to me {#blank#}10{#/blank#} it's possible to give without expecting anything in return.

    Smart phones were once the best thing to happen to the tech industry. In the 11 years since the iPhone made its debut, smart phones {#blank#}1{#/blank#}（include）just about every other gadget. And it is surprising that it {#blank#}2{#/blank#} alter every business.

    But {#blank#}3{#/blank#} smart phones have achieved dominance, revolution is again in the air.

    At Google's and Apple's recent developer conference, executives took the stage to show how much more irresistible they were making our phones. Then each company unveiled the software {#blank#}4{#/blank#}（help）you use your phone a lot less.

    There's reason for this seemingly contradictory engineering effort, and it's{#blank#}5{#/blank#} I call “Peak Screen”.

    For much of the last decade, a technology industry {#blank#}6{#/blank#}（rule）by smart phones has pursued a singular goal of completely {#blank#}7{#/blank#}（conquer）our eyes. Tech has now captured pretty much all visual capacity. Americans spend three to four hours a day looking at their phones, and that's the minimum estimation.

    So tech giants are to build the beginning of something new: a {#blank#}8{#/blank#}（visual）tech world, a digital landscape{#blank#}9{#/blank#} relies on voice assistants, headphones, watches and other wearables to take some pressure off our eyes.

    We may simply end up adding new devices to our screen-addled lives, {#blank#}10{#/blank#} it could change everything again. As I argued, in many ways screens have become to dominant in our lives. The sooner we find something else, the better.
