Read the dialogue and then decide whether the statements that follow are true or false. Write True or False in your answersheet:
A planet is a body in space that revolves around a star. There are nine planets in our solar system, and these nine planets travel around the sun. The names of the planets are Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune, and Pluto. Planets travel in orbits around their stars . All of the planets of the solar system revolve in elliptical orbits. In other words, their orbits are like large, flat circles. The time that it takes a planet to make one revolution around the sun is called its year. The Greek were the first people to recognize and give names to some of the planets. The word planet comes from a Greek word meaning wanderer. If a person wanders, this means that he goes from one place to another and does not have a home. The Greek thought that the planets “wandered” in the sky. However, modern scientists can predict the movement of the planets very accurately
____ 1/ A planet revolves around the Earth.
____2/ Venus, Mars and Neptune are planets and stars.
____ 3/ The Greek were the first to recognize some of the planets.
____ 4/ The planets in our solar system travel around the sun and in elliptical orbits
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
35. Pluto may not be a planet, according to some scientists.
36. Scientists have got enough information about the universe

‘Super-Earth’ 40 light years away is best chance of finding life outside Solar System, say scientistsPoint 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.
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 .
Start with :
I think that there is no life on Mars . Firstly .......

Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.
True or False sentence:
1....................Solar energy can be cheap and clean.
2....................Most of our electricity now comes from nuclear power.
3....................the solar energy that gets to the Earth cannot provide enough power for the world's population.
4....................Solar energy can be used on cloudy days.
5....................All buildings in Sweden will be heated by solar energy in 2050.
There is much more water than land...the surface of the earth. The sea and oceans... nearly four-fifths of the whole world,and only one-fifth of ...land. If you traveled over the earth...different directons, you would have to spend much more of your time ... on water than on roads or railways. We sometimes forget that ...every mile of land there is four miles of water. There is much water on the surface of our earth that we... to use two words to describe. We use the word seas to...those parts of water surface which... only a few hundreds of miles wide, the word oceans to describe the huge areas of water which are thousands of miles wide... very deep.
