VI, Read the passage and circle the best option A, B, C or D to complete the following questions or
statements:
The Sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its center that convert
hydrogen to helium. The Sun has existed in its present state for about four billion six hundred million years
and is thousands of times larger than the Earth. By studying other stars, astronomers can predict what the
rest of the Sun’s life will be like. About five billion years from now, the core of the Sun will shrink and
become hotter. The surface temperature will fall. The higher temperature of the center will increase the rate
of thermonuclear reactions. The outer regions of the Sun will expand approximately 35 million miles, about
the distance to Mercury, which is the closest planet to the Sun. The Sun will then be a red giant star.
Temperatures on the Earth will become too high for life to exist. Once the Sun has used up its
thermonuclear energy as a red giant, it will begin to shrink. After it shrinks to the size of the Earth, it will
become a white dwarf star. The Sun may throw off huge amounts of gases in violent eruptions called nova

explosions as it changes from a red giant to a white dwarf. After billions of years as a white dwarf, the Sun
will have used up all its fuel and will have lost its heat. Such a star is called a black dwarf. After the Sun
has become a black dwarf, the Earth will be dark and cold. If any atmosphere remains there, it will have
frozen over the Earth’s surface.
66. It can be inferred from the passage that the Sun ______.
A. is approximately halfway through its life as a yellow dwarf
B. will continue to be a yellow dwarf for another 10 billion years
C. has been in existence for 10 billion years
D. is rapidly changing in size and brightness
67. What will probably be the first stage of change for the Sun to become a red giant?
A. Its surface will become hotter and shrink.
B. It will throw off huge amounts of gases.
C. Its central part will grow smaller and hotter.
D. Its core will cool off and use less fuel.

Read the below passage on Mars and use the information to write a composition about the possibility of life on the planet .

There has long been speculation concerning about the possibility of life and liquid water on Mars . However , the planet's thin atmosphere prevents water from accumulating for any time over significant portions of the planet . Some evidences of the planet's surface suggest the presence of liquid water at some point in history , but scientists think this water would be too salty or acidic to support life as we know it . Futhermore , fierce solar winds and poor heat transfer across its surface would make sustained life virtually impossible . There is compelling evidence , however , that Mars was once much more habitable to life than it is today .

Some theories of the purpose of dreams

Freud believed that we dream so that we can release the deep, secret desires that we are not allowed to express in real life because of the rules of polite society. Most people know about Freudian dream analysis – a dream about a train going into a tunnel is a dream about sexual intercourse. But couldn’t it just be a dream about travelling on a train?

Another theory is that dreams allow us to solve problems that we can’t solve in real life. We go to sleep with a problem and wake up with the answer. This may be more of a way to ‘use’ our dreams than a ‘purpose’ of dreaming. If you believe that your dreams are important then analysing them may help you to focus your mind on the problem and help you to find the solution.

The modern image is that dreams are the brain’s way of cleaning up the computer’s hard disk, organizing the events of the day into folders and deleting the rubbish that it doesn’t want to keep. But we all know that very little of what we dream every night is concerned with what happened to us that day.

Another idea is that dreams are the brain’s way of practising the behaviour that we need to survive. So we dream about being chased by a monster because one day it might happen! It’s a bit like a pianist practising her scales every day even though she doesn’t need to use them at that moment.

Others believe that dreaming is the brain’s way of exercising the pathways between the brain cells. This may be an important element in why we sleep rather than why we dream. We die if we don’t sleep but we can live without dreaming. Some patients with brain injuries lose the ability to dream but don’t seem to suffer any ill-effects.

REM and dreaming

Scientists used to think that dreaming only happened during Rapid Eye Movement sleep (REM). REM sleep is essential for all mammals. We all become irritable and depressed without it. If we don’t have enough REM one night, we will compensate by having more the next. REM is generated by the brainstem – the oldest and most primitive part of the brain. So scientists used to believe that dreaming was also caused by activity in the brainstem. We now know that dreaming can happen at any time during sleep. The only difference seems to be that it’s easier to remember dreams that happen during REM.

Babies have a lot more REM activity than adults, but research shows that they dream less. The same may be true of animals. We know that they have REM activity but that doesn’t mean they dream.

It also seems that dreaming is a skill that develops as you get older, like language for example. Young children’s dreams are very different from older children’s or adult’s dreams.

New research

Modern technology has allowed scientists to map the parts of the brain that are active when we dream. The primitive brainstem is very active, but so are other important areas at the front of the brain. These are the frontal lobes that control emotion, memory, and experiences that come through the senses like hearing and vision. If these areas are injured, the person stops dreaming. On the other hand, the areas that control rational, logical thought are not active at all. This could explain why dreams are so strange. They have no logical sequence or time, which makes them very difficult to explain to other people when we wake up. Dreams combine recent events with long past events and our emotions while we are dreaming are often very strong.

Psychologists have also done studies on people who kept dream diaries for long periods of time (up to fifty years in some cases) and have found that what we dream is very much connected with how we think and behave when we are awake. So an extrovert, adventurous person will have extrovert, adventurous dreams. A shy person will be a shy person in her dreams. People who are important to us will often be in our dreams and so will things that worry us or make us happy.

So what’s the conclusion?

Well, nobody really knows. But scientists are now suggesting that dreams have absolutely no purpose at all. When we are awake we are ‘thinking’ all the time. Some of this thinking is useful and has a purpose. But we often just ‘think’ about nothing in particular while we’re waiting for the bus or walking to work. And that’s what the brain is doing when we are asleep - just thinking. Sometimes it’s interesting and sometimes it’s boring.

Doing the research for this article has made me more interested in my dreams rather than less. I might even start a dream diary! But nothing that I’ve read explains why I sometimes have an embarrassing dream about finding myself standing completely naked at a bus stop. Fortunately, this has never happened to me in real life, and it isn’t something that I think about when I’m awake. I’m told that it’s an example of a ‘universal dream’ – a dream that is common to people all over the world. Dreaming about flying is another example. So what’s the explanation? We can’t all be ‘just thinking’ about the same thing, can we?

It is also considered to be a vengeance when it is also an interest that I can live in this society. Setting foot in society encounters a lot of obstacles and difficulties for yourself because thankfully I have loved ones besides also considered but more than the people in the world, I don't think so right from the beginning, I just thought of being banished as I was in prison that I was wrong because after all it was the silent thing that helped me the river in this society. Besides, the pressures and frustrances of what you have done and so do I have nothing for the hour and the fitting I have to live for over time, but I like to kill my childhood and the time of death that has made me lose the things I desire
