correct answer to each of the questions from 30 to 34
Arid regions in the southwestern United States have become increasingly inviting playgrounds for the
growing number of recreation seekers who own vehicles such as motorcycles or powered trail bikes and
indulge in hill-climbing contests or in carving new trails in the desert. But recent scientific studies show
that these off-road vehicles can cause damage to desert landscapes that has long-range effects on the area’s
water-conserving characteristics and on the entire ecology, both plant and animal. Research by scientists
in the western Mojave Desert in California revealed that the compaction of the sandy arid soil resulting
from the passage of just one motorcycle markedly reduced the infiltration ability of the soil and created a
stream of rain runoff water that eroded the hillside surface. In addition, the researchers discovered that
the soil compaction caused by the off-road vehicles often killed native plant species and resulted in the
invasion of different plant species within a few years. The native perennial species required many more
years before they showed signs of returning. The scientists calculated that roughly a century would be
required for the infiltration capacity of the Mojave soil to be restored after being compacted by vehicles.

A. Problems caused by recreational vehicles
B. Types of off-road vehicles
C. Plants of the southwestern desert

C. Roads through the desert
D. New plant species
Question 32. According to the passage, the damage to plants is ______
A. unnoticeable
B. superficial
C. long-lasting
D. irreparable
Question 33. According to the passage, what happens when the soil is compacted?
A. Little water seeps through

B. Better roads are made
C. Water is conserved
D. Deserts are expanded
Question 34. What is happening to the desert hillsides?

B. The surface is being irrigated
C. There are fewer types of plants growing on them
D. There are fewer streams running through them.

Shyness may not seem to be a serious complaint, but for some who suffer from it, it can become
unbearable. Even talking to a small group of people you know can seem like an ordeal – it can feel as if
you’ve been asked to give a speech on a topic you know very little about to a number of experts. You start
to feel hot and shaky, your heartbeats faster, your knees feel weak, you begin to stutter and the whole
experience seems to last forever.

The fact of the matter is that shyness is something we often recognize in others: blushing is one
of the more visible sighs, for example. Yet we do not judge someone harshly because of this. But shyness
does mean you are harder to approach, so you become more isolated. As one shy person put it, “It’s like
being in a prison, and it’s very hard to break out.”
Experts on the subject have come up with various possible solutions, and one has been singled out
as being the key to success, namely, finding an interest in common with other people. Spending a lot of
time on the sidelines watching other people and envying them because they are much more outgoing
doesn’t help; remembering that some of the people you envy most are probably shy themselves. The secret
is how you deal with it. And experts have come up with four things you can do today to help. Firstly, you

can start by listening to other people. You will find yourself getting interested in what they’re talking
about and asking questions, and before you know it, you’ll be behaving a conversation. Secondly, you
could try asking neighbors if you can walk their dog. Like children, pets can be excellent icebreakers for
conversations with passers-by. Thirdly, try joining a class to learn something like tapdancing or flamenco,
where people are likely to laugh a lot. You’ll feel relaxed, and also you’ll be much too busy concentrating
on what you are doing to feel shy. Lastly, try telling yourself that it doesn’t matter if you say or do
something silly. Most people make a fool of themselves every so often, and it’s not the end of the world
if you do.

A. sweating a lot.
B. an increased heart rate.

A. Studying others’ behavior in social situations.
B. Discovering shared interests with others.
C. Comparing yourself to other people.
D. Finding out what makes other people shy.
Question 39. How can listening to others prove helpful in combating shyness?
A. You develop useful psychological skills.

B. It’s the first step to getting into conversation.
C. People will see you care about their interests.
