For the last few months I have spent every Saturday in my flat and have done nothing more
exciting than work at home, read the newspapers and watch television. I had begun feeling,
bored with this and so, last weekend I though I would do something different. I rang up several
of my friends and we decided to go to London for the day. I was really excited as I hadn't been
to London since I was ten. We decided to go by coach as this was by far the cheapest means of
transport that was available even though it meant that we needed to get up very early. Once in
London we decided to take a sightseeing tour as we wanted to see some of the famous

buildings. After the tour we bought some sandwiches and ate them in a small park. In the
afternoon two of us went shopping and the others went to the theater. We met up again at 6:30
p.m. and went to a small restaurant in Soho. The meal was really good but, unfortunately, it
took much longer than we had expected. We had to get a taxi back to the coach station.
Luckily, we got there just two minutes before our coach left.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate

the correct answer to each of the questionsfrom 28 to 32.

It has been thought that women are the second class in citizen, and men are the first. There is
not a real equality of opportunity for men and women. Years ago, people were living in a
man-dominated society. Women had to obey their husbands and fathers absolutely. Women' s place
was in the kitchen and women' s work was housework. In many places, women were not even
allowed to go to school. Women had no rights, even the right to choose husband for

themselves. Men usually occupied high positions in society so they thought they were more
intelligent than women. Men often considered women as their property. Sometimes, they were
mistreated by their husbands and suffered the problem as a fate. Many parents did not even
want to have daughters.

Despite the progress, there remain outdated beliefs about women' s roles, traditionally passed
down from generation to generation. Men are commonly seen as the strong bodies,
bread-winners in the family and key leaders in society, while women are restricted to being
housewives and child bearing and care, and housework such as washing and cooking.

According to social surveys, many women in the 21st century still have to work over 12 hours a
day including working in offices and doing countless household chores without any help from
their husbands. In some regions, the labor of women is not recognized despite the hardships
they endure to support the whole family. Moreover, women are the direct victims of family
violence, especially in rural areas.

Thanks to the women' s liberation movement, nowadays women have proved that they are
equal to men in every aspect. An average woman has weaker muscles than an average man
but she may be as intelligent as he is. Women can do everything that men can, and women can
do one thing that no man can: they produce children.

Question 28: Which was not women' s role in the former days?
A. Bearing and rearing children B. Working in authority

C. Doing housework D. Doing cooking

Question 29: Years ago, women were not allowed ________.
A. to stay at home with their parents B. to do housework
C. to work in the kitchen D. to go to school

Question 30: What did women have to suffer?
A. Enjoy their housework B. Illiteracy

C. Good schooling D. Choosing a husband themselves

Question 31: The outdated beliefs about women' s roles ________.
A. was forced to change after the women's liberation movement
B. have been eradicated completely

C. still exist at present.

D. disappeared soon after the women's liberation movement

Question 32: According to the text, women in the 21st century ________.
A. get help from their husbands with all housework

VI. Read the passage and choose the best answers.

Rainforests circle the globe for twenty degrees of latitude on both sides the equator. In that
relatively narrow band of the planet, more than half of all the species of plants and animals in
the world make their home.

Sever hundred different varieties of trees may grow in a single acre, and just one of those trees
may be the habitat for more than ten thousands kinds of spiders ants, and other insects. More
species of amphibians, birds, insects, mammals and reptiles live in rainforests than anywhere
else on earth.

Unfortunately, half of the world's rainforests have already been destroyed and at the current
rate, another 25 percent will be lost by the year 2000. Scientists estimate that as many as fifty
million acres are destroyed annually. In other words, every sixty seconds, one hundred acres of
rainforest is cleared. When this happens, constant rains- erode the former forest floor, thin layer
of soil no longer supports plant life, and the ecology of the region is altered forever. Thousands
of species of plants and animals are condemned to extinction and since we aren't able to

predict the ramifications of this loss to a delicate global ecology, we don't know what we may be
doing to the future the human species as well.
