From {#blank#}1{#/blank#} early age he was interested in plants. He {#blank#}2{#/blank#} (study) agriculture in college and as a young teacher he began experiments in crop breeding. He thought that the key to {#blank#}3{#/blank#} (feed) people was to have more rice and to produce it more quickly.

    As an elderly couple was about to shut their phones off onboard a flight to Australia via Abu Dhabi, they noticed a {#blank#}1{#/blank#} (miss) call from their son-in-law. The plane was starting to roll forward on the runway when they {#blank#}2{#/blank#} (see) the text: Their grandson was in special care with {#blank#}3{#/blank#} serious illness. If they didn't get back soon, they might miss their chance to say goodbye.

The couple got the attention of the Etihad Airways crew,{#blank#}4{#/blank#}rushed to tell the pilot. Instead of {#blank#}5{#/blank#} (ignore) their beg to stay on schedule, the kindhearted pilot turned the plane back around to the Manchester Airport gate.

    A hear-warming {#blank#}6{#/blank#} (arrange) was made. From there, the rest of the staff jumped in to get {#blank#}7{#/blank#} (they) home as fast as possible. Some collected their bags and helped the couple through the airport, while others brought their car to arrivals so the grandparents could head straight home. The airline said they could use their tickets another time.

    “I've been in the travel business for {#blank#}8{#/blank#} (decade) and never heard of this happening,” the couple's travel agent, Becky Stephenson, told the BBC. They were aware {#blank#}9{#/blank#} the importance of saying goodbye for the couple, so they offered to help.

    The boy passed away the next day, when his grandparents would have been in Australia, but they reached his bedside in time to say goodbye. The couple felt greatly {#blank#}10{#/blank#}(thank).

    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.

    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".
