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

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

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.

The word “there” in the last sentence of paragraph 4 refers to _______.

A. our own planet                   

B. the core of a black dwarf

C. the outer surface of the Sun          

D. the planet Mercury
