It was Sunday, December 7, 1941.     1     usual, the wake-up call came at 5:45 a.m. It looked like it was going to be a normal day on board the ship. Just then there was a huge crashing sound from above. The ship shook       2     (violent) and the men looked at each other in horror. Above their heads, hundreds of Japanese planes circled like eagles. They were diving down to drop bombs on Pearl Harbor. Moments later, a bomb hit the USS Arizona.

The surprise attack came as a great shock to     3     whole nation. The next day, President Roosevelt made his famous Pearl Harbor Speech,     4     (ask) the US Congress to declare war on Japan. In     5     (respond) to the attack and the president’s address, the US     6     (join) World War Ⅱ. Today, the USS Arizona lies     7     it sank: in the middle of the Pacific Ocean. Its location     8     (mark) with a memorial shaped like a bridge, which crosses the ship’s sunken     9     (remain). Although about eight decades years has passed, the attack on Pearl Harbor, one of the     10     (dark) episodes in American history, will never be forgotten.

In the summer of 1405, Zheng He set sail from Taicang on his first voyage. His ships     1     (load) with china, silk, tea and other treasures as gifts for foreign rulers. Zheng He's seven voyages had a far­reaching impact     2     China and its neighbours. Zheng He's efforts helped develop and strengthen     3     (harmony) relations with these countries and regions. Zheng He's accomplishments are now     4     (wide) acknowledged, and he is remembered as one of China's most influential explorers.

Columbus was born in a port city of Italy in 1451. As a teenager, he loved sailing, and he showed great interest in geography,     5     inspired him to begin his career as a seaman. Columbus insisted on     6     (search) for a direct sea route to the East Indies by sailing across the Atlantic Ocean. On 3 August 1492, he     7     (depart) from Spain with three ships carrying about 90 crewmen. Regardless of all the challenges, Columbus managed     8     (keep) everyone out of danger with his knowledge and     9     (brave) across the ocean. Finally, on 12 October, the crew spotted land in     10     distance. His voyages opened a new chapter of the Age of Exploration, a period which witnessed many important geographical findings.

The celebrations with the military parade for China's 70th anniversary（周年纪念日）on National Day have clearly shown     1     this nation has developed quickly with confidence in the system     2     (adopt) under the leadership of the Communist Party of China (CPC).

On the one hand, National Day     3     (say) that China at 70 has achieved scientific and technological developments. On the other hand, it also reminded     4     (we) of the suffering the country experienced after the Opium War of 1840.

The parade also told the     5     (story) of "Made in China" and "Created in China". The achievements did not fall     6     the sky and nor were they stolen. Instead, they were the result of the hard work,    7    (wise) and courage of the Chinese people.

Under the leadership of the CPC, the Chinese people have created     8     miracle in 70 years. The truth of socialism with Chinese characteristics     9     (prove) by history and practice to be a correct path. It has become evident that China will     10     （sure）achieve the goal of the great renewal of the Chinese nation.

7 . The Battle of Chancellorsville, one of the most famous battles of the Civil War, took place in Virginia in the spring of 1863. For months, the two armies had been staying on opposite banks of a narrow river. The Confederate(南方联盟) troops were led by perhaps     1     (honored) military tactician(战略家) in American history, General Robert E. Lee. The Union (北方联盟)soldiers were led by “Fighting” Joe Hooker.

In appearance, personality, and lifestyle, these men were nearly perfect opposites. Lee, an older man in poor health with a gray beard, had a solemn, measured character. Hooker was a blond, broad-shouldered young man     2     pride over his appearance was but one aspect of his self-centeredness. Whereas Lee was loyal and principled, Hooker was known for his rollicking enjoyment of both women and whiskey.

Despite the fact that the Confederacy     3     (win) the last four major battles and the Union soldiers were starving,     4     (exhaust), and demoralized, Hooker proclaimed, “My plans are perfect. And when I start to carry them out,     5     God have mercy on Bobby Lee, for I shall have none.” Why was Hooker so confident?

Hooker had used spies, analysts, and even hot air balloons to compile a vast amount of intelligence about Lee’s army. He had already been aware, for example,     6     Lee had only 61,000 men to Hooker’s own 134,000. Supported by his superior numbers, Hooker secretly moved 70,000 of his men fifteen miles up and across the river, and then ordered them to sneak back down to position themselves     7     Lee’s army. In effect, Hooker had cut off the Confederate soldiers in front and behind. They were trapped. Satisfied with his advantage, Hooker became convinced that Lee’s only option was to retreat to Richmond, thus     8     (assure) a Union victory.

Yet Lee, despite his disadvantages of both numbers and position, did not retreat. Instead, he moved his troops into position to attack. Union soldiers who tried to warn Hooker that Lee was on the offensive     9     (dismiss) as cowards. Having become convinced that Lee had no choice but     10     (retreat), Hooker began to ignore reality. When Lee’s army attacked the Union soldiers at 5:00 p.m., they were eating supper, completely unprepared for battle. They abandoned their rifles and fled as Lee’s troops came shrieking out of the brush, bayonets drawn. Against all odds, Lee won the Battle of Chancellorsville, and Hooker’s forces withdrew in defeat.

Woodblock printing first appeared in the early Tang period. During the Song dynasty, the technique of block printing was very advanced. Books were     1    (beautiful) printed. Even today the books     2    (print) at the time are valuable and treasured by libraries and book collectors.

However, block printing     3    (be) not very convenient. Every two pages of a book had to be carved on a woodblock, and a big book would require many blocks. Besides, there had to be large places for storing the books.     4     (overcome) these shortcomings, Bi Sheng invented the movable type during the years between 1041 and 1048. One word was carved on one piece of clay,     5     was hardened with fire. Then clay characters were set on     6     iron plate according to the text of a book. Then ink was applied to them and     7    (sheet) of paper spread over them, and the printing was done. Bi Sheng’s invention made printing faster and     8    (easy) than before. Later, movable type of metal and wood was made and widely used.

The technique of printing was gradually known to other Asian countries and Europe. The great influence printing had     9    the advance of civilization is too clear to need any     10    (explain).
