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.

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.
5. According to the passage, how is a ship kept upright in a dry dock?

A. 　It is lined with concrete.

B. 　It is placed on keel blocks.

C. 　It is fastened to the shore.

D. 　It is supported with pieces of wood.

143.The school is( )in the low-income housing area.

A. 　precious

B. 　 located

C. 　 estimate

D. 　 temperature

1、Passage 12More and more people like bicycling and it is no surprise. It is fun, healthy and good for the
environment. Maybe that‘s why there are 1.4 billion bicycles and only 400 million cars on roads
worldwide today. Bikes can take you almost anywhere, and there is no oil cost!
Get on a bicycle and ride around your neighborhood. You may discover something new all
around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You
can bike to work and benefit from the enjoyable exercise without polluting the environment. You
don‘t even have to ride all the way.
Folding bikes work well for people who ride the train. Just fold the bike and take it with you.
You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take
a common bike with you when you fly. But be sure to look for information by getting on airline
websites. Not all airlines are bicycle-friendly to travelers.
Health Benefits of Bicycling:
It helps to prevent heart diseases.
It helps to control your weight.
A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a
year.
It can improve your mood.
Exercise like bicycling has been shown to make people feel better, more relaxed and
self-confident.
Bicycling is healthier than driving.
2. When you are riding your bicycle around your neighborhood, you may ________.

A. 　pollute the environment around

B. 　find something you didn‘t notice

1、Passage 15There is a commonly held myth that Einstein was an underachiever at school, but it really
isn＇t true. While he may have had difficulties with languages, Einstein excelled in physics,
mathematics and music. Einstein held many patents and was a keen inventor.
While working at Swiss patent office in Bern he took it upon himself to write his own
scientific papers in his spare time, mostly at weekends and in the evenings after work. 1905 was
Einstein＇s miracle year. During this year he wrote three fundamental papers, any of which would
have guaranteed him immortality in the world of physics.
His first was on a new understanding of the structure of light. Einstein argued that light is
composed of small particles of energy, called photons, as well as oscillating waves.
The second paper built upon the theory of kinetics. Einstein explained how atoms were
responsible for the buffeting of particles of material in suspension, like cigarette smoke suspended
in air. This paper presented the first direct evidence for the existence of atoms, vindicating an idea
that had been around for over 2000 years.
His third paper of 1905 was ―On the Electrodynamics of Moving Bodies‖. Here Einstein
derived the theory of ―special relativity‖. In a supplementary paper four months later, he
formulated the famous equation, E=mc2, where mass and energy are equivalent, showing that a
very small amount of mass converts to a huge amount of energy. This is the driving force behind
atomic bombs, and all the stars in the Universe.
5. Which of the following words can be used to best describe the author‘s attitude towards
Einstein?

A. 　Skeptical.

B. 　 Critical.

C. 　 Admiring.

D. 　 Exaggerated.

91.A college degree and some working experience should( )you for the job advertised inthe newspaper.
