The sun is our nearest star, and all of our energy comes from it. The sun sends out very large amounts of energy every day. We call this energy solar energy or radiant energy. Without the sun, life on earth would not exist because our planet would be totally frozen. We use this solar energy in many different ways. The sunlight lets us see and warms us.

Plants use the light from the sun to grow. They store it as chemical energy. The energy is stored in their roots, fruits, and leaves. This energy feeds every living thing on the earth. When humans and animals eat plants, and the food made from plants, we store the energy in our bodies, in our muscles and in our brain cells.

We use this energy for everything we do. We use energy when we sing a song, think a thought, tell a joke, climb a ladder, make a pizza, or run a race. Everything needs energy!         

 

27. The sun is the farthest star from our planet.

28. Radiant energy is another name of solar energy.

29. Life on earth would exist if there were no sun.

30. Chemical energy is just stored in leaves.

31. Both human and animals eat food made from plants.

32. We store energy in our bodies, in our muscles and in our brain cells.

When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it-at this moment in time.

It appears probable, however, that sunlight will be the color we know for only a negligibly small part of the Sun's history. Stars, like individuals, age and change. As we look out into space, We see around us stars at all stages of evolution. There are faint blood-red dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit, there are searing ghosts blazing at 100, 000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature; today(and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun's light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves.

That yellow "hump" will shift as the Sun evolves, and the light of day will change accordingly. It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel-which it is now doing at the spanking rate of half a billion tons a second- it will become steadily colder and redder.

1. What is the passage mainly about?

(A) Faint dwarf stars (B) The evolutionary cycle of the Sun

(C) The Sun's fuel problem (D) The dangers of invisible radiation

2. What does the author say is especially important about the Sun at the present time?

(A) It appears yellow (B) It always remains the same

(C) It has a short history (D) It is too cold

3. Why are very hot stars referred to as "ghosts"?

(A) They are short- lived. (B) They are mysterious.

(C) They are frightening. (D) They are nearly invisible.

4. According to the passage as the Sun continues to age, it is likely to become what color?

(A) Yellow (B) Violet (C) Red (D) White

5. In line 15, to which of the following does "it" refer?

(A) yellow "hump" (B) day (C) Sun (D) hydrogen fuel

Help me! Thank you!

Space exploration is much too expensive and the money should be spent on more important things. What is your opinion?

It's often argued that space exploration is too expensive and the money should be spent on more important things. This essay disagrees with that suggestions completely because of the benefits space exploration brings to the people. The essay will first look at how space exploration has effected in our life and then discuss how it would help the human in the future.
First of all, a plethora of technologies we are using nowadays was invented based on space research. The scientists launch the satellite into space. Then they will the information from it to work out new ideas. For example, we can see roads, houses, restaurants, schools,.e.t.c on the Google Map very clearly. It's because the satellites send photos they have taken to the centre on the Earth. This helps me a lot because I often feel arduous while try to find the correct road.
Furthermore, the population of the world is increasing day by day. This is the reason why we should find out a new planet that we can live in. I think this is quite possible and this will affect a lot in our life. For instance, finding a new planet that we can live in can decrease some problems which are caused by high population such as the traffic jam, the pollution and there is not enough food, job and houses for people today.
In recapitulation, space exploration should be improved to make further technologies and solve the serious problem on the Earth that we are facing.​
