Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.
And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.
We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised itstides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.
These small pieces have been going round the sun ever since. They are the planets.
【小題1】Most stars are _________________________.
A．following a regular path in space
B．moving about without a fixed course
C．seldom wandering about in the universe
D．a(chǎn)lways travelling together
【小題2】Some two thousand years ago, the mountain on the sun was raised probably because _____________.
A．the star moved away from the sun

【小題3】The article suggests that _______________.
A．how space formed
B．our earth exists before the sun
C．no one knows where the earth comes from

【小題4】The expression “the cause of the disturbance” refers to ________.
A．the large tidal waveB．the powerful tidal pull
C．the star coming near the sunD．one of sun’s planets

A．where the planets in the universe came from

It’s a goal for millions and millions of families every year to keep the Christmas spending within a certain amount of money, but you can still afford the gifts because your loved ones will enjoy them. This concern (憂慮) is becoming greater and greater theses days. Even so, there are several things that you can do to help.

Hit the sales. No one wants to get up at four o’clock in the morning and fight to get a good deal (交易) on Black Friday ( the first Friday at Christmas time). It’s surely very difficult to pick up the courage and get out there in the cold for a good deal. But sometimes it can be well worth. Many retailers (零售商) offer specials all through the day. Some even offer online Black Friday specials, so we may still be able to get a great deal on Black Friday.
Read advertisements regularly. Once the Christmas shopping season is coming, retailers will be hungry for business. They will try their best to get us into the store. Please read the weekly advertisements of sales among the major retailers from time to time. We may be lucky enough to find different prices for the same thing in different shops.
Shop online. Some of us don’t like running from store to store to get the best price on the perfect gift. Some of us don’t like to go out in the cold at all, and then, we can do online shopping.
The world of online shopping makes it possible for us to visit all the major retailers and some
specialty stores on the Internet. We can find exactly what we are looking for at the best possible price without even having to leave the house. With traditional Christmas shopping, it will always take us a long time to wait if we want to get the perfect gift.
【小題1】 The underlined word “specials” in Paragraph 2 means______.
A．贈(zèng)品B．奢侈品C．特價(jià)商品D．圣誕禮品
【小題2】We can have more choices to get a good deal ______.
A．on the Internet B．in specialty stores C．from salesmenD．from retailers
【小題3】In this passage the writer wants to ______.
A．tell us to shop online
B．tell us the best way to do shopping
C．show us how hard it is to do Christmas shopping
D．give us advice on how to get a good deal at Christmas time
【小題4】 From the passage we can infer (推斷) that ______.
A．people are surely able to get a good deal on Friday
B．it is possible for people to buy the perfect Christmas gifts with less money
C．retailers will be hungry because they are busy selling Christmas gifts
D．with traditional Christmas shopping, people can’t buy the perfect gifts
