New research suggests     1     the story of Franklin’s famous experiment with lightning may be fiction instead of fact. More than one generation of school children has been amazed by his bravery and his     2     (science) approach to     3     (look) for the truth. However, neither the story nor the details of the experiment are entirely true. Although it has been proved that Franklin’s experiment     4     (take) place, more than one scientist has questioned what really happened.     5     detail about the string and the key is true. But     6     (science) all agree that if he had     7     (actual) touched the key, he would certainly have died from the electric shock. Fiction is     8     (interesting) than the truth. People have been more inspired by Franklin’s spirit of scientific     9     (explore) than by the facts themselves. But in science, facts should be proved     10     experiments and research.

Throughout history, mankind has been working hard on the space     1     (explore) to learn more about the universe though it was thought     2     (possible) before the mid-20th century. However, so many scientists were     3     (determine) to make the human dream to explore space     4     (realize). With the first satellite launched and orbiting around Earth     5     (success), Yuri became the first astronaut     6     (send) into space in 1961. After that, American astronaut Neil Armstrong succeeded in stepping onto the moon. Although the failure of Challenger was     7     (disappoint), human beings went on with their desire to explore the universe, the International Space Station being the best example.

    8     (follow) Russia and America, China became the third country in the world to send humans into space     9     (independent) in 2003,     10     Yang Liwei successfully orbited Earth. From then on, China has made great progress in space exploration. Shenzhou 6 and 7 were sent into space, the Tiangong 2 docked with Tianzhou 1, and Chang’e 4 landed on the moon.

In 1937, the aggression of the Japanese army brought disaster to China's three great     1    (university): Peking University and Tsinghua University     2     (occupy) by Japanese troops, while Nankai University was completely destroyed by bombing.     3     (save) their educational and intellectual heritage, the three universities joined together in Kunming as National Southwest Associated University, otherwise known     4     Lianda.

Despite the immense hardships and the daunting challenges, it was right in this place, over a period of eight long years,     5     the nation's intellectual heritage was not only guarded but fortified by the passion and belief of the worthy academics of Lianda.

With the country at war, students at Lianda were not going to shirk their duty.     6     (drive) by a sense of commitment, a great many joined the army to resist the Japanese invaders and defend the honour of the nation.

A product of the war, Lianda is now     7     (physical) gone.     8     it has become the crowning glory of China's modern universities, not only because of its prominent professors and talented students, but also because of the school's strong spirit of perseverance and     9     (dedicate).

More than eighty years on, the priceless contribution of Lianda still needs to be reaffirmed. It     10     (become) part of the collective memory of the Chinese nation, with its spirit as the blueprint for all universities in China in the modern era.

Code-named "Operation Overlord", it was the     1     (large) combined sea, air and land operation in history, the aim being     2     (free) north-west Europe from German occupation.

Meanwhile, thousands more were journeying across the English Channel to Normandy,     7     (protect) by fighter planes in the skies above them. Their objective was clear: to reach the Normandy beaches along about 80 kilometres of French coastline. The fiercest fighting was at Omaha Beach. The enemy were hiding, ready to attack the Allied soldiers even before they reached land. Boats were hit and men drowned,     8     those who did make it to the beach faced heavy machine gunfire. By mid-morning, hundreds lay dead in the water and amongst the tanks on the beach. But, despite the high cost in human life, the D-Day landings were     9     success and were seen     10     (wide) as the beginning of the end of the Second World War.

Because this was Li Qiang's first trip, he was worried and     1    （settle）so that he suffered from "time lag".     2    （hit）by a lack of fresh air, his head ached.
