In recent years,sandstorms {#blank#}1{#/blank#}(occur) in China frequently,especially in northwestern areas, {#blank#}2{#/blank#}severe influence has caused wide concern in China.

There're several reasons for this.First of all,people are cutting down trees without planting more, {#blank#}3{#/blank#}(make) some land become deserts.Another reason is {#blank#}4{#/blank#}it rains less due to the environment pollution.

    To {#blank#}5{#/blank#}(efficient) prevent sandstorms,first,we should plant more trees and grass which can keep the soil {#blank#}6{#/blank#} being washed away.Second,more green fences should {#blank#}7{#/blank#}(build) along the desert, {#blank#}8{#/blank#}it helps to control the process of the desertification.

    Let's take action to do what we can {#blank#}9{#/blank#}(prevent) sandstorms from today.Soon the golden days we have been looking forward to {#blank#}10{#/blank#}(come).

    In the USA the high school graduation ceremony is of great {#blank#}1{#/blank#}(important). 12th grade students, or seniors, who are about 17 or 18 years old, look forward to {#blank#}2{#/blank#} (attend) this event.

    The graduation ceremony itself takes place at the end of May or beginning of June, which usually {#blank#}3{#/blank#} (include) music awards, and a guest speaker. After the speech, students walk to the front of the room to receive their diplomas from the headmaster. Students start preparing for graduation a long time {#blank#}4{#/blank#} it happens. They order rings designed {#blank#}5{#/blank#} (special) for their class.

    Another tradition is to have their photographs{#blank#}6{#/blank#}(take). These photographs are used{#blank#}7{#/blank#} the class yearbook, which is a printed book about all the students in the school. Students have special cards called announcements printed to send to friends and relatives to tell them about their graduation. The cards often include{#blank#}8{#/blank#} invitation to the ceremony. If you receive it, you should send a present {#blank#}9{#/blank#}money to the graduate. A few weeks before the ceremony, the students are measured the cap that they will wear at the ceremony. After the ceremony,{#blank#}10{#/blank#} (family) usually have graduation parties for friends and relatives. It's a day and a night that high school seniors remember for a long time.

    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.

    Tik Tok, {#blank#}1{#/blank#} launched in China as "Douyin" in September 2016, describes {#blank#}2{#/blank#} (it) as a forum to capture and present the world's creativity, knowledge, and precious life moments{#blank#}3{#/blank#} (direct) from the mobile phone. It is owned by Bytedance, a startup {#blank#}4{#/blank#} (base) in China that is considered one of the world's most valuable private companies.

    Tik Tok users tap and hold{#blank#}5{#/blank#} (record) a short video and can add music and visual effects. The videos can then be uploaded with hashtags to join a variety of topics and trends.

    Most of the videos, which tend to last around 15 seconds, show someone dancing, lip-syncing (对口型) {#blank#}6{#/blank#} a song or a video clip, or pulling some kind of running gag (笑料), {#blank#}7{#/blank#} the app has also gained followings among some particular groups, especially military personnel.

    Part of the charm and {#blank#}8{#/blank#} (attract) of Tik Tok is that its younger users have embraced it as a place to experiment with the kind of Internet humor that {#blank#}9{#/blank#} (not succeed) on other platforms yet. Kevin Roose in the New York Times called the app a refreshing outlier in the social media universe that brought him {#blank#}10{#/blank#} rare sensation of "happiness".

    A teahouse is a special house which primarily serves tea and other light refreshments(茶点). Its function varies widely{#blank#}1{#/blank#}(depend)on the culture. In China, a teahouse is a place {#blank#}2{#/blank#}people gather to enjoy tea, chat and socialize. It {#blank#}3{#/blank#}(consider) as a symbol of Chinese tea culture and people's leisure lives.

    Chinese teahouses enjoy a long-standing history. They developed from tea {#blank#}4{#/blank#}(stand) in the Western JIN Dynasty, took shape in the Tang Dynasty, developed {#blank#}5{#/blank#}(gradual) in the Song, Yuan, Ming and Qing Dynasties and became booming in modern times.

    In the Song Dynasty, teahouses spread all over the cities and villages, at a rate comparable with that of restaurants. The owners preferred to decorate their teahouses {#blank#}6{#/blank#}paintings of celebrities or rare and precious plants {#blank#}7{#/blank#}(attract) customers. In the Ming and Qing Dynasties, the number of teahouses went beyond that of restaurants, gaining much {#blank#}8{#/blank#} (wide) popularity and becoming more famous. Later, the acculturation(文化植入)of western culture forced traditional Chinese teahouses to take on{#blank#}9{#/blank#} new look.

    Since reform and opening-up, with the rapid development of the economy and evident improvement of people's living standards, teahouses{#blank#}10{#/blank#}(flower) in China.
