VI. Read the passage carefully, then decide whether the following statement are true (T) or false (F).
Mars, commonly referred to as "the red planet," is the fourth planet from the sun. Its reddish color comes from the high amounts of iron oxide on its surfaco. Mars has surface features similar to those found on the moon and on Earth. It has ranges, volcanic fields, valleys, ice caps, canyons and deserts. Mars is much smaller thàn the Earth. It has approximately half the radius of Earth. Mars orbits the Sun a little further than Earth. Mars takes 686 days to orbit Sun. In other words, the orbital period of Mars is almost twice as long as Earth's orbital period. Many spacecrafts have attempted to visit Mars, the most notable of which was NASA's Mariner 4, the first to.visit in a fly-by in 1965. In 1976, Viking 1 and 2 became the first spacecrafts to conduct successful and sustained landings on Mars. They provided the first color photographs of the "red planet."
32. The red color of the Mars comes from the sand on its surface.
33. The Earth is four times larger than Mars.
34. It takes Mars much longer to orbit the Sun than it does Earth.
35. Viking 1 and 2 were the first spacecrafts to visit Mars.
36. The first color photographs of Mars were provided by Viking landers.

VI.Read the passage carefully, tlien decide whot hen the following,statement are true T) or false (F)
There are nine planets in our solar system. These planets each have their atmosphere and environmental conditions. Scientists have been trying to research other planets to see if it is possible for life to exist on the other eight own bodies in space.
Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.
Many scientists also believe that our solar system is not alone in the uni- with us. It is difficult to know if there is life present elaewhere in the universe. for many years to come. yerse. Many believe there are several other systems that share the uhiverse .The universe is a complex structure of space that may continue to be a mysterey for many years to come
32. There are nine planets in our solar system, besides Earth.
33. It is difficult to study the planet Mercury because it is very close to the sun.
34. We don't know much about Pluto even though we can see it up close

‘Super-Earth’ 40 light years away is best chance of finding life outside Solar System, say scientists

Point a high-powered telescope at the constellation Cetus, the sea monster, and it is just possible to make out a dim red dwarf star shining in the tail. Although it might seem unspectacular, orbiting around that star is a rocky planet that could hold the answer to whether we are alone in the universe.

Scientists say the planet is a ‘Super-Earth’ which is the best place to look for signs of life outside of the Solar System. Early indications suggest it has an atmosphere, and sits within the ‘Goldilocks Zone’ where it is neither too hot nor too cold for liquid water to exist.

And it is only 40 light years from Earth meaning that it could be possible to send a signal. The planet was found by an international team of scientists who have been studying data from European Space Observatory’s High Accuracy Radial velocity Planet Searcher (HARPS) instrument which looks for regular changes in brightness of stars, which suggests a planet is passing by in orbit.

A Mission to Mars

Have you ever had a dream of traveling to another planet in our solar system? If you have, there is an actual programme that is happening right now, and it hopes to send people to Mars in 2023. Known as the Mars One Mission, it will send a crew of four people on a one -way mission to colonize Mars. Those chosen people will have to be ready to say good-bye to the earth forever, as there will not be a return trip. For the people chosen, they will have to learn to do many different things. First of all, they will be living the rest of their lives with just a handful of other people, so they all must have personalities that allow them to get along. Second, the living quarters that they will have won’t be very spacious, so they will have to deal with that condition as well. If they feel homesick, they will only be able to communicate with people back on the earth via e-mail, video and audio sent back and forth. However, there won’t be any real-time communication. Even at the speed of light, communication between the earth and Mars takes about 20 minutes. Whether the Mars One Mission will actually happen is the big question that a lot of people are asking. There is an enormous skepticism in the science community, and Wired magazine gave the mission a miserable score of two out of ten on its probability scale. However, for those who dream of going to Mars, at least they can say there is a possibility that it could happen.

1, Who might like to go on this mission ?

A. People who get along with thers

B. People who get homesick easily

C. People with angry personalities

D. People who don't like to communicate

2, What will NOT happen to the people who go on the Mars One Mission ?

A. They will communicate with people on the earth

B. They will have to live with other people

C. They will live in quarters that don't have a lot of space inside

D. They will return to the earth

4. Which of the following is considered miserable ?

A. A crew on board of the Mars One Mission

B. A score of the programme on the probability scale

C. A personality of people taking part in the programme

D. A mission of astronauts to the ISS

5. How long will it take for a message to come back from Mars ?

A. Around 20 minutes

B. Only a few seconds

C. Almost immediately

D. About an hour

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 questions.

Earth is richly supplied with different types of living organisms which co-exist in their environments, forming complex, interrelated communities. Living organisms depend on one another for nutrients, shelter, and other benefits. The extinction of one species can set off a chain reaction that affects many other species, particularly if the loss occurs near the bottom of the food chain. For example, the extinction of a particular insect or plant might seem inconsequential. However, there may be fish or small animals that depend on that resource for foodstuffs. The loss can threaten the survival of these creatures and larger predators that prey upon them. Extinction can have a ripple effect that spreads throughout nature.

In addition to its biological consequences, extinction poses a moral dilemma for humans, the only species capable of saving the others. The presence of humans on the planet has affected all other life forms, particularly plants and animals. Human lifestyles have proven to be incompatible with the survival of some other species. Purposeful efforts have been made to eliminate animals that prey on people, livestock, crops, or pose any threat to human livelihoods. Some wild animals have been decimated by human desire for meat, hides, fur, or other body parts with commercial value. Likewise, demand for land, water, and other natural resources has left many wild plants and animals with little to no suitable habitat. Humans have also affected nature by introducing non-native species to local areas and producing pollutants having a negative impact on the environment. The combination of these human-related effects and natural obstacles such as disease or low birthrates has proven to be too much for some species to overcome. They have no chance of survival without human help.

As a result, societies have difficult choices to make about the amount of effort and money they are willing to spend to save imperiled species. Will people accept limits on their property rights, recreational activities, and means of livelihood to save a plant or an animal? Should saving such popular species as whales and dolphins take priority over saving obscure, annoying, or fearful species? Is it the responsibility of humans to save every kind of life form from disappearing, or is extinction an inevitable part of nature, in which the strong survive and the weak perish? These are some difficult questions that people face as they ponder the fate of other species living on this planet.

What does the passage mainly discuss?

Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s
fossil fuels are running out. What would happen if there were no oil, coal and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy
from the sun, the wind and the water.
Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for
rain, and to maintain the temperature of the planet. All are necessary for human life. If we’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.
11. We are asking the question “What would happen if there were no oil, coal and gas on earth?” because ___.
A. we are now depending so much on fossil fuels.
B. we are looking forward to seeing great changes.
C. we are looking for other alternative sources of energy.
D. other sources of energy can come from the sun, the wind and the water.
12. Which of the following can NOT be used as alternative sources of energy?
A. coal/gas B. the sun/the water
C. the sun/the wind D. solar energy/nuclear power
13. Centuries ago, people used wind power to ___.
A. maintain the earth’s temperature B. get water from underground
C. grow plants D. generate electricity
14. Up till now, water energy has been used for ___.
A. similar purposes C. the textile industry
B. moving ships D. different purposes

Good evening. Welcome to our Science for Fun Program. This week, we’ve received a lot of questions asking about life on the moon. We’ve talked to some experts and this is what we’ve found out. There is no water or air on the moon. It is all silent because there is no air. Of course, there will be no music, no sounds. There are no rivers and no lakes. At night, it is very cold. The temperature goes down 151⁰C below zero. But during the day the temperature rises to 100 ⁰C above zero.

There are great round holes on the moon. They look like big lakes. They are called craters. There are more than 30,000 craters on the moon. There are also high mountains. The highest mountains on the moon are about 26,000 feet or 8,000 meters high.

And here is something very interesting to know: on the moon you weigh one sixth of what you weigh on earth. If you weigh 50 kilos, on the moon you will weigh only a little more than 8 kilos. You will be able to jump very high, even higher than an Olympic Champion. You can take very long steps as well. And … may be you want won’t sleep very well because one day on the moon lasts for 2 weeks.

So, is there life on the moon? I’ll leave the question for you to answer yourself.

……16. There is no air on the moon.
……17. There are rivers and lakes on the moon.
……18. There are no sounds on the moon.
……19. It is very cold at night on the moon.
……20. During the day the temperature is even lower.
……21. There are great round holes on the moon.
……22. There are no mountains on the moon.
……23. You will weigh 8 kilos heavier on the moon.
……24. You will be able to jump very high on the moon.
……25. One day on the moon lasts for two weeks.
