Ten Chinese engineers were driving down a road to a NationalForest Park.

    They were{#blank#}1{#/blank#}(sudden) amazed by what they saw. Three tall animals,{#blank#}2{#/blank#}(cover) with long black hair, werecrossing the road. On {#blank#}3{#/blank#}(see) the animals, the engineers immediately stopped and ran after them. However, when they saw {#blank#}4{#/blank#}move through the forest with great speed and strength, they did not dare to follow any {#blank#}5{#/blank#}(far).

    The men did not take any photographs but scientists were delighted by the {#blank#}6{#/blank#}(discover), because the engineers are all well educated people and scientists feel they canrely on what they {#blank#}7{#/blank#}(describe).

    Scientists returned to the forest, collected some hair and measured footprints, {#blank#}8{#/blank#}are about 20 inches. They appear to be the animals' feet! Chinese scientist have now set upa special group to exchange information and made a study of the forest. But inthe meantime, some people refuse to believe that this half-man, half-monkey {#blank#}9{#/blank#}(exist). They will not believe it {#blank#}10{#/blank#}oneof the animals have been caught.

    Today, with most of us{#blank#}1{#/blank#}(own) a smartphone that lets us post to social media wherever and whenever we want, oversharing has become {#blank#}2{#/blank#}(hard) to avoid{#blank#}3{#/blank#} the tricky thing is {#blank#}4{#/blank#}people usually don't realize they{#blank#}5{#/blank#}(overshare) when they post information on the Internet. The problem can only{#blank#}6{#/blank#}(bring) to light by our friends and family.

    A survey showed that every two{#blank#}7{#/blank#}three people in the US think their friends share too much on social media.

    Oversharing can have{#blank#}8{#/blank#} (apparent) negative impacts. For starters, a leak（泄露）of personal information may put your bank account at risk. Plus, It may also jeopardize（危及）your current or future job if you, for example, trash-talk your{#blank#}9{#/blank#}(employ) on social media or write about how you got {#blank#}10{#/blank#} (drink) during office time.

China used to be called the "Kingdom of Bicycles" in the 1980s and the 1990s, but since then, cars {#blank#}1{#/blank#} (take) over the country. Because of traffic jams, {#blank#}2{#/blank#} can be difficult to travel across major Chinese cities. Even {#blank#}3{#/blank#} (go) a few kilometers can take up to an hour. Now, new apps that help people use bikes are being used more and more across cities.

Cheng Li started using bike share services about six {#blank#}4{#/blank#} (month) ago. He said now he was using a car less and the metro (地铁) {#blank#}5{#/blank#}. "After I get off the metro, I usually have to walk another kilometer or two, so I'll grab a bike share and go. It is convenient."

    For many, it is great to have shared bikes. {#blank#}6{#/blank#}, many of its bike share stations were not placed in convenient places. Now, it is easy to find a bike, and to register with {#blank#}7{#/blank#} smartphone.

    Meanwhile, there is now a lot of {#blank#}8{#/blank#} (compete) among bike ——sharing providers because of their {#blank#}9{#/blank#} (popular). Some providers are trying to flood the streets with bikes to be more visible. Sometimes there are so many bikes that they {#blank#}10{#/blank#} (complete) block the sidewalks.

    Because deaf people can't hear, they have special ways of communicating. For example, they can learn to understand{#blank#}1{#/blank#}someone is saying by looking at the mouth of the speaker. This{#blank#}2{#/blank#}(call) lipreading. Also, speaking is very difficult for the deaf, because they can't hear{#blank#}3{#/blank#}(they) own voices. However, it is possible with special training. According to many deaf people all around the world, the most {#blank#}4{#/blank#}(practice) and popular way of communicating is with sign language.

    When I was in high school our physics teacher gave us a challenge {#blank#}1{#/blank#} involved making a paper airplane of any shape. The only objective was to get it to fly as far as possible. {#blank#}2{#/blank#} (stand) at the starting line, one of my classmates took a piece of flat paper, crumpled (把…捏成一团) it up, and {#blank#}3{#/blank#} (throw) it down the way. He beat the class with ease. Some of the students got mad and said that he cheated, but the physics teacher {#blank#}4{#/blank#} (clear) explained it could be any shape and that a paper ball was indeed a shape.
