1、Passage 19Throughout her working life, a ship — like a motorcar — must be serviced regularly if she
is to remain efficient. After a period at sea she must be overall checked and any necessary repairs
must be made. There are also instances when a ship must be converted from being one kind of
carrier to another. Most of today‘s oil, for example, is carried by huge super-tankers. The smaller
tankers, many of which are still in good condition, can be converted into bulk carriers（散货船）
for the transport of sugar, coal or ore.
Conversion or repair work is carried out in a dry dock, a huge hole cut into the ground and
lined with concrete. At one end are large gates separating the dock from the river or sea. When
these gates are opened, water pours into the dock and fills it. A ship can then enter the dock, where
it is carefully fastened in an upright position.When the ship is positioned inside the dock, the gates are closed and the water is pumped out.
The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the
ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure
that the ship rests evenly on the keel（龙骨）blocks to prevent damage being done.
As soon as the ship is firmly positioned, repair or conversion work can begin on her body or
superstructure.

1、Passage 7Greek soldiers sent messages by turning their shields toward the sun. The flashes reflected
light could be seen several miles away. The enemy did not know what the flashes meant, but other
Greek soldiers could understand the message.
Roman soldiers in some places built long rows of signal towers. When they had a message to
send, the soldiers shouted it from tower to tower. If there were enough towers and soldiers with
loud voices, important news could be sent quickly over distance.
In Africa, people learn to send messages by beating on a series of large drums. Each drum
was kept within hearing distance of the next one. The drum beats were sent out in a special way
that all the drummers understood. Though the messages were simple, they could be sent at great
speed for hundreds of miles.
In the eighteenth century, a French engineer found a new way to send short messages. In this
way, a person held a flag in each hand and the arms were moved to various positions representing
different letters of the alphabet. It was like spelling out words with flags and arms.
Over a long period of time, people sent messages by all these different ways. However, not
until the telephone was invented in America in the nineteenth century could people send speeches
sounds over a great distance in just a few seconds.4. The _______ way of communication made use of visible signs.

1、Passage 2
Man has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them, for example, was the great Italian artist, Leonardo Da Vinci. In the 16th century he made designs for machines that would fly, but they were never built.
Throughout history, other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead, he fell to the ground and broke every bone of his body and rested in peace.
The first real step took place in France, in 1783. Two brothers, the Montgolfiers, made a very large ―hot air balloon‖. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year, the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about.1.Leonardo Da Vinci( ).

B. 　built a kind of machine which never flew

C. 　made designs for flying machines
