It's amazing that Chinese police are using facial-recognition tech to catch criminals. Police in Beijing are reportedly testing out new smart glasses with facial-recognition technology. The smart tech, which {#blank#}1{#/blank#} (use) in many checkpoints to find suspects presently.

    Some people will certainly be worried about the possibility of police using facial-recognition tech to flag individuals, {#blank#}2{#/blank#} the chief executive thinks that there is no reason {#blank#}3{#/blank#} the concern, because he trusts the government. {#blank#}4{#/blank#} (Interesting), this is not the first time that facial recognition has been used to stop wrongdoers in Beijing. In 2017, we reported on how visitors were having their faces scanned automatically in a certain restroom in {#blank#}5{#/blank#} capita] city to prevent locals from {#blank#}6{#/blank#} (steal) the paper for use at home.

    Authorities in Shenzhen, China, have also set up artificial intelligence-powered CCTV cameras to scan the faces of those {#blank#}7{#/blank#} cross the streets unlawfully and display their {#blank#}8{#/blank#} (identity) on large LED screens for all people to see.

    If that isn't punishment enough, plans are now in place {#blank#}9{#/blank#} (link) the current system with cellular technology, so offenders will also be sent a text message with a fine as soon as they are caught {#blank#}10{#/blank#} (cross) the road against traffic lights.

    The Great Wall was listed as a World Heritage by UNESCO in 1987. Just like a dragon, it winds up and down across deserts, grasslands and mountains, {#blank#}1{#/blank#}(run) approximately21,196 kilometers from east to west.

    The {#blank#}2{#/blank#} (construct) of the Great Wall was not that easy, {#blank#}3{#/blank#} drew heavily on the local resources for building materials. The walls were {#blank#}4{#/blank#} (original) built in the Spring ＆Autumn Period and the Warring States Period. Emperor Qin Shi Huang succeeded in his effort to have them joined together. Since then, the Great Wall {#blank#}5{#/blank#}(serve) as a monument of the Chinese nation throughout history.

    With {#blank#}6{#/blank#} history of about 2,700 years, some parts of the Great Wall are now {#blank#}7{#/blank#}ruins or have disappeared. However, the Great Wall of China is still one of the most appealing{#blank#}8{#/blank#} (attraction) all around the world owing to its historical significance. The best-known part of the Great Wall of China, Badaling, {#blank#}9{#/blank#}(locate) 43 miles northwest of Beijing, attracts thousands of national and foreign tourists every day.

    Today, the Great Wall {#blank#}10{#/blank#} (recognize) as one of the most impressive architectural achievements in history.

    The computer is widely used in our daily life. The computer is a machine that {#blank#}1{#/blank#}(design) to help people do many things. When it first came into {#blank#}2{#/blank#}(be), it was just a calculating machine, and later it was built as an analytical machine that could “think” logically and produce an answer {#blank#}3{#/blank#}(fast) than any other person. Still later, the computer could be made to work as a “universal machine” to solve any difficult mathematical problems. There were times when its size was {#blank#}4{#/blank#}(total) changed. It became smaller and smaller but it got cleverer and clever. In the early 1960s, computers were connected by network and brought into common people's homes {#blank#}5{#/blank#}(deal) with information and help communication {#blank#}6{#/blank#} people around the world. It could share {#blank#}7{#/blank#}(inform) with others and they could talk to each other. The Internet has become {#blank#}8{#/blank#} important part in our life and we can do many things with the help of the Internet. The computer is used to connect people {#blank#}9{#/blank#} aren't close enough to speak to each other. It has been serving the human race since {#blank#}10{#/blank#}(it) birth.

    If you go out to the fields at night in spring or summer, you can hear frogs singing {#blank#}1{#/blank#}（joy） here and there. It seems as if they were performing a field symphony.

    The frog is a good and useful creature that benefits human beings. They can catch fast-moving insects. Each frog eats a large number of pests that are harmful{#blank#}2{#/blank#}crops. This little creature is regarded{#blank#}3{#/blank#}the natural enemy of pests".

    {#blank#}4{#/blank#}now frogs are getting fewer and fewer. This is because they are killed and put on the table as a delicious dish by their chief enemy, human beings. It is {#blank#}5{#/blank#}shameless and cruel act, isn't it?{#blank#}6{#/blank#}cause responsible for the rapid reduction of frogs is that farmers use insecticides （杀虫剂）to kill pests and frogs get killed as a result of drinking poisoned water{#blank#}7{#/blank#}eating poison-killed insects.

    Something must be done without delay{#blank#}8{#/blank#}（save）frogs. If we don't punish those{#blank#}9{#/blank#}sell and kill frogs to make money, then one day all of us {#blank#}10{#/blank#}（punish） by nature for failing to keep the balance of nature.
