Holidays
in
the
United
States
usually
occur
at
least
once
a
month.
Most
months
have
a
national
holiday
that
has
been
arranged
to
be
celebrated
on
a
Monday.
The
holidays
have
all
been decided to be celebrated on a Monday so that the workers may have 3-day weekends--- that
is, Saturday, Sunday and Monday in order to rest or travel or do things with their families. Major
holidays in the United States such as New Year’s Day or Christmas Day or the day, when we
remember the first settlers of the United States, called Thanksgiving Day are celebrated all over
the
country.
During
these
holidays
most
businesses
close
and
the
workers
stay
home
and
celebrate with their family.
Vacation
can
be
from
2
weeks
a
year
to
4
weeks
a
year.
This
usually
depends
on
how
long
you’ve been working for a company, what type of position you have, whether you have a very
high position or a very important position and it’s difficult to find someone to replace

you. In this case, you might take a few days at a time rather than taking one month all at once.
Usually
the
more
time
you
spend
working
for
a
company,
the
more
time
you
may
get
for
vacation.

Why don’t birds get lost in their long migratory flights? Scientists have been puzzle
d over
this question for many years. Now they’re beginning to fill in the blanks.

Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours.
But what about birds that fly mainly at night? Tests with artificial stars have proved conclusively
that certain night-flying birds are able to follow the star in their long- distance flights.
One
such
bird---a
warbler(
鸣禽
)---had
spent
its
lifetime
in
a
cage
and
never
flown
under
the
natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was
placed
under
an
artificial
star-filled
sky
at
migration
time.
The
bird
tried
to
fly
in
the
same
direction as that taken by his outdoor cousins. Any change in the position of the make-believe
stars caused a change in the direction of his flight.
Scientists think that warbler, when flying in daylight, use the sun for guidance. But the stars are
apparently their principal means of navigation. What do they do when the stars are hidden by
clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and
river courses. But when it’s too dark to see these, the warblers circle he
lplessly, unable to get
their bearings.
1.
The reason why birds don’t get lost in migratory flights

A. have been known to scientists for years .
B. have only recently been discovered.
C. are known by everyone.

D. will probably remain a mystery.
2. The experiment with the warbler indicated that
A. birds have to be taught to navigate.
B. a bird that has been caged will not migrate.
C. some birds cannot fly at night.

D. some birds seem instinctively to follow the star when flying at night.
3. Under artificial stars, the bird in the cage
A. tried to fly in the same direction as birds not caged .
B. changed direction when the position of the stars was changed.
C. would not fly at all.

D. both A and B.
4. Warblers migrate
A. from North American to the Falkland Islands.
B. only once during their lifetime.

C. using what is apparently an inborn navigational ability.

D. when they are freed from their cages.
5. This article is a good example of the way scientists
A. jump to conclusion.
B. discover workable answers to general questions by studying particular cases.

C. formulate a law and then carry out investigation.

D. are frustrated by the habits of animals.

Social customs and ways of behaving change. Things which were considered impolite many
years ago are now acceptable. Just a few years ago, it was considered impolite behavior for a
man to smoke on the street. No man who thought of himself as being a gentleman would make a
fool of himself by smoking when a lady was in a room.
Customs
also
differ
from
country
to
country.
Does
a
man
walk
on
the
left
or
the
right
of
a
woman in your country? Or doesn’t it matter? What about table manners? Should you use both
hands when you are eating? Should you leave one on your lap, or on the table?
The Americans and the British not only speak the same language but also share a large number
of
social
customs.
For
example,
in
both
America
and England
people
shake
hands
when
they
meet each other for the first time. Also, most Englishmen will open a door for a woman or offer
their seat to a woman, and so will most Americans. Promptness is important both in England and
in America. That is, if a dinner invitation is for 7 o’clock, the dinner guest either arrives close to
that time or calls up to explain his delay.
The important thing to remember about social customs is not to do anything that
might
make
other people feel uncomfortable, especially if they are your guests. There is an old story about a
man who gave a formal dinner party. When the food was served, one of the guests started to eat
his peas with a knife. The other guests were amused or shocked, but the host calmly picked up
his knife and began eating in the same way. It would have been bad manners to make his guest
feel foolish or uncomfortable.
1. If one has accepted a dinner invitation, what should he do if he is to be late for the dinner?
A. He should find an excuse.
B. He should ask for excuse.
C.
He should say “Sorry”.

D. He should telephone to explain his being late.
2
.
“It
would
have
been
bad
manners
to
make
his
guests
feel
foolish
or
uncomfortable.”
“Bad
manners: means ___.
A. ugly
B. dishonest
C. impolite
D. shameful
3. Which of the following do you think is the best title for this passage?
A. Social Customs and Behavior
B. Social life
C. American and British Customs
D. Promptness Is Important
4. According to the text, the best host ___.
A. tries his best to make his guests feel comfortable

There have been many great inventions, things that changed the way we live. The first great
invention was that is still very important today --- the wheel. This made it easier to carry heavy
things and to travel long distances.
For hundreds of years after that there were few inventions that had as much effect as the wheel.
Then in the early 1800’s the world started to change. There was little unknown land left in the
world. People didn’t have to explore much anymore. They began to work instead to make life
better.
In the second half of the 19
th
century many great inventions were made. Among them were the
camera, the electric light and the radio. These all became a big part of our life today.
The
first
part
of
the
20
th

century
saw
more
great
inventions.
The
helicopter
in
1909,
sound
movies in 1926, the computer in 1928, and jet planes in 1930. This was also a time when a new
material was first made. Nylon came out in 1935. It changed the kind of clothes people wear.
The
middle
part
of
the
20
th

century
brought
new
ways
to
help
people
get
over
disease.
They
worked very well. They made people healthier and let them live long lives. By the 1960s most
people could expect to live to be at least 60.
By this time most people had a very good life. Of course new inventions continued to be made.
But man now had a desire to explore again. The world is known to man but the stars are yet.
Man began looking for ways to go into space. Russia made the first step. Then the United States
took a step. Since then other countries, including China and Japan, have made their steps into
space.
In 1969 man took his biggest step away form earth. Americans first walked on the moon. This is
certainly just a beginning though. New inventions will someday allow us to do things we have
never yet dreamed of.
1. ___ inventions had had as much effect as the wheel before the 19
th
century.
A. Quite a number of
B. Some
C. Few
D. Many other
2. Nylon came out nearly at the same time as ___.
A. the radio B. the camera
C. jet planes
D. the movies

5
. We can safely come to
the conclusion that people’s lives
will be
made even better through

The
whole
body
is
covered
with
skin.
The
surface
of
the
skin
is
dead
(like
the
hair
and
nails), but it is made from a living layer just under the surface. The outside dead layers wear off
all the time, with new ones replacing them, and the body forms a totally new skin every three

weeks.
The skin protects the body from the outside world and it passes in information from the outside.
It helps to keep water in the body and to keep the body at the same temperature. Bacteria (germs)
cannot get in through the skin unless it is damaged.
If the weather is cold, the blood vessels on the skin squeeze (
挤压
) down, or contract, so that as
little blood as possible comes near the surface. This means that less warmth is lost to the outside.
This makes the skin look pale, or even “blue”. At the same
time, the hairs on the skin are pulled
upright by tiny muscles.
When it is hot, the blood vessels expand, or get wider again, to allow plenty of blood to run near
the surface of the skin. This helps the body to loose heat, and the skin may look red. At the same
time, The sweat glands produce more sweat, which cools the skin down.
If
the
skin
has
ever
been
numb,
you
will
realize
how
important
the
feeling
from
the
skin
is.
Nerves in the skin are sensitive to heat and cold, sharpness, hardness and softness, wetness and
dryness and pain. If one is not able to feel these things, which can act as warning, he is likely to
be burned, cut or hurt in other ways.
The color of the skin depends on special color cells. These are just below the top layers of the
skin. They are needed as protection from some of the harmful rays of the sun. The stronger the
sun, the more important it is to have a dark skin. People with pale skins may “tan(
晒黑
)” in the
sun. This happens when the body produces extra color cells in the skin for protection. In the sun,
the skin produces a vitamin (vitamin D) which is needed for strong bones.

A.
There is skin all over one’s body.

B.
The skin of one’s body will be completely
different in three weeks.
C. The surface of the skin is made of a living layer

2. The second paragraph of the passage mainly talks about.
A. the functions of the skin
B. the temperature of the skin

C. the information from the skin
D
.
the water in one’s body

3. When will bacteria get in through the skin?
A. When one is ill.

B. When the bacteria are strong enough.
C. When the skin is cut.
D. When the temperature is very low.
4. When the weather is cold, the skin will contract in order to
A. make more blood come near the surface.

Many of the world’s pollution problems have been caused by the crowding of large groups
of people into the cities. Supply for the needs of the people leads to further pollution by industry.
