Originally constructed around 256 BCE by the State of Qin     1     an irrigation and flood control system, Dujiangyan is a remarkable example of ancient engineering skill and is still     2     use today.

During the Warring States period, people who lived along the banks of the Min River     3     (trouble) by annual flooding. Qin governor and irrigation engineer Li Bing investigated the problem thoroughly. He led a team     4     (construct) a levee(堤坝) to redirect a part of the river’s flow. Then they cut     5     channel through Mount Yulei to let the water flow through it. After the system was finished , no more floods     6     (occur). What’s more, it made Sichuan one of the most productive agricultural     7     (region) in China because the redirected water from the Min River could be used for irrigation. If you visit Dujiangyan, you will see an     8    (usual) construction that looks like a fish’s mouth. This famous attraction, Yuzui, together with two other important parts, namely, Feishayan and Baopingkou, was     9     (scientific) designed to control the water flow throughout the year.

    10     (recognize) as a UNESCO heritage site, Dujiangyan has irrigated farms while preventing floods for over 2,000 years.

On April 23, 1912, the luxury steamship Titanic hit an iceberg, and the “unsinkable” ship     1     (sink) in the Atlantic Ocean. The world was     2     great shock. But few know that there were six Chinese among the 705 survivors. Now, people can learn about their history through a documentary called The Six: The Untold Story of RMS Titanic’s Chinese Passengers, which     3    （release）on April 16, 2021.

“The historical materials keep records of who they are, where they come from, the families of the survivors except the six” Arthur Jones,     4     documentary’s director, told China Newsweek magazine. It was in 2015     5     Jones heard the six people’s story from his friend Steven Schwankert for the first time. They then decided to cooperate to reveal the buried history. Among the limited records, they came upon the Titanic’s passenger list,     6     had eight Chinese names on it.     7     (collect) more information, the production team spent five years     8     (travel) 20 cities in different countries as well as reading 100 documented works.

Rumor (谣言) has it that these Chinese survivors dressed as women to fight for     9     (spot) on lifeboats, but they found it untrue. Jones hopes the movie will reach a wide     10     (globe) audience, and perhaps even more people who secretly suspect they have a connection with the Titanic story.

Famous British physicist Stephen Hawking,     1     mental genius (智力天才) and physical disability made him a household name and inspiration across the globe, has died at age 76 on March 14^th, 2018.

Propelled (推动) to superstar by his 1988 book A Brief History of Time, which became     2    unlikely worldwide bestseller, Hawking devoted    3    (he) to unlocking the secrets of the Universe.

Hawking refused to accept the predictions that he would only live for a few years after developing a form of motor neurone disease (运动神经元病) in his early     4    (twenty). The illness gradually robbed him of mobility (移动的能力)    5    (leave) him confined to a wheelchair, almost completely paralysed and unable to speak except through his voice synthesizer (合成器). It was with these difficulties     6     he revised the draft of A Brief History of Time which was published in 1988.

    7     (translate) into thirty languages, the book has sold over ten million copies worldwide and lives on as a science book that continues to captivate (迷住) and inspire new readers each year.

When I came into contact with the book, I did not know much about the time and space. Was there a     8     (begin) of time? Could time run backwards? …These questions may be with all of us during our childhood.     9    (lucky), Stephen Hawking shows us the time and the space, the God and a mystery. The book, A Brief History of Time, is available in paperback and I     10     (strong) recommend it. For me, books like A Brief History of Time are more captivating (迷人的) than any novel.
