The government has made enough laws to fight pollution. The cities in Australia have got little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well.
Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers’ exhibition. There we saw a large number of wild flowers we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers’ exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quickly as we could. There were about three hundred sheep coming towards us down the path.
Australia is famous for its sheep and kangaroos (袋鼠). After a short drive from any town, you will find yourself in the middle of white sheep. Sheep, sheep, everywhere are sheep.

Apollo 11, carrying Neil Armstrong, Edwin Aldrin and Michael Collins, was launched on 16 July, 1969. Five days later they stepped down onto the moon.
Neil Armstrong
On the way there: Of all the wonderful views we had, the most impressive to me was on the way to the Moon when we flew through its shadow. We were still thousands of miles away, but close enough so that the Moon almost filled our window. The moon appeared blue-grey. It seemed almost as if it were showing us its roundness, its similarity in shape to our Earth, in a sort of welcome. I was sure it would be a hospitable（好客的） host. It had been waiting for its first visitors for a long time.
After touch down: The sky is black, you know. It’s a very dark sky, but it still seemed more like daylight than darkness as we looked out the window. It’s a very strange thing but the surface looked very warm and inviting. It seemed to be tan(棕褐色). It’s hard to explain that, because later when I held the material in my hand, it wasn’t tan at all. It was black, grey and so on.
Edwin Aldrin
On the Moon: The blue color of my boots has completely disappeared now into this soil—still don’t know what color to describe this other than grayish(灰色的) cocoa.
Back on board: The moon was a very natural and pleasant environment in which to work. On the Moon, in one-sixth gravity, you have a strong feeling of being somewhere. As we did our experiments, some objects we threw away would go in a slow, lazy manner.

If you are ever planning to buy a telescope and want to get yourself involved in astronomy it is always a good idea to know a bit of the sky.Get acquainted with a few constellations(星座) so that it will be easier for you to spot the constellations when you are using your telescope.

It’s a good idea to buy a few magazines on astronomy to help you to get familiar with the constellations in the sky and also read a few reviews on the different types of telescopes in the market.This will help you gather all the information that is out there regarding telescopes and what people have to say about them.

It’s advisable to go in for a pair of binoculars(双筒望远镜) before you buy your first telescope so that you can get used to spotting constellations before your view of the sky is narrowed down.This will also help you know if you really want to get involved in astronomy.Many people buy a costly telescope and then discover that they’re not actually interested in astronomy.

Experience has no substitute，and there certainly is nothing better than using different telescopes before you buy one.This will help you to get the feel of all the types of telescopes and you will know which one is easier for you to use.A large aperture(光圈) refractor(折射) may give you an excellent image but you may not be able to keep a steady hand while using it resulting in a blurry image.

There are three types of telescopes that are available in the market.If you want a more elegant looking telescope you can always choose to buy a fine brass telescope.It’s good to become acquainted with each type before going for the plunge of a first telescope.The first type of telescope is the refractor telescope，which uses lenses to gather light to a focus at the eye piece.The use of lenses helps the telescope have a superior image.A refracting telescope is not as portable as the other two types of telescopes and so you will have to buy one with a small aperture.

The second type of telescope is the Reflector.Made by Sir Isaac Newton，this telescope functions by focusing the light back at the front of the tube，which is where the eyepiece sits，by using parabolic(抛物线的) mirrors and another smaller mirror to deflect the light.There is no added color in the image caused by refraction of light since this telescope does not use lenses.These are the cheapest of all telescopes and are more portable than refractors.

Today is Sunday. The sky is full of sunshine; so does my life. At about 9:00 a.m., I go to the bookstore with my friends. There was a lot of new books. I didn’t know which one to buy, because these books were all useful to me. At last, I chose two. At 10:00, we went to the cinema. The film calling Titanic was very popular. It took us about 3hours to see. Having seen a film, everyone was deeply moved. Some friends even burst into tear. From the story, I understand that love is noble but valuable. That’s a real wonderful film. It is well worth seeing again.

What a happy day! I hope tomorrow I will be even happy!
