Often, when you buy a computer, the laptop（手提电脑）bag is overlooked, but it is one of the most valuable things a computer owner can have. Most choose a laptop simply because they want to be able to transport it from place to place. 1. The bag not only protects the computer from dirt or damage, it can also be used to carry other laptop parts, such as spare batteries, a computer mouse and any portable equipment you may have.

The first thing to consider when choosing the best laptop bag is what style of bag you may want. The most common styles are the briefcase（公文包）and the backpack. 2.The briefcase gives a sense of professionalism while the backpack may be easier to carry much of the time.

A laptop bag should have both a computer sleeve along with several separate sections. The sleeve helps keep the laptop from moving too much in the bag. The sections are good for storage of documents and other things you may want to transport along with the computer; 3.

Another thing when you buy a laptop bag is making sure it is strongly sewed and has a solid bottom. These two things will make your bag much stronger, especially if it is the backpack style.4. In some cases, it may just be a few months before a computer owner needs a new one. However if made properly, laptop bags can last five or more years.

5. Buying a cloth bag may be a cheaper option, but leather bags are generally made better and are able to stand up to use much better Besides, leather offers a natural barrier to water when the computer is transported through rain or snow.

A.Obviously the former is more important, though.

B.Each one has their own advantages as laptop bags.

C.Materials also make a difference, especially in the briefcase style.

D.But without a good laptop bag, that becomes much more difficult

E.There are lots of choices when it comes to choosing the best laptop bag.

F.This will prevent them rubbing up against the computer and scratching it.

G.Choosing a cheap bag without these could greatly reduce the life of the bag..

The temperature of the sun is over 5,000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center. The sun is so much hotter than the earth that matter can exist only as a gas, except at the core. In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core. However, no one really knows, since the center of the sun can never be directly observed.

Solar astronomers do know that the sun is divided into five layers or zones. Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core. The first three zones are regarded as the sun’s atmosphere ends and the main body of the sun begins.

The sun’s outermost layer begins about 10,000 miles above the visible surface and goes outward for millions of miles. This is the only part of the sun that can be seen during an eclipse such as the one in February 1979. At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun’s rays.

The corona is a brilliant, pearly white, filmy light, about as bright as the full moon. Its beautiful rays are a sensational sight during an eclipse. The corona’s rays flash out in a brilliant fan that has wispy spikelike (一束束穗状) rays near the sun’s north and south poles. The corona is thickest at the sun’s equator.

The corona rays are made up of gases streaming outward at tremendous speeds and reaching a temperature of more than 2 million degrees Fahrenheit. The rays of gas thin out as they reach the space around the planets. By the time the sun’s corona rays reach the earth, they are weak and invisible.

1.Matter on the sun can exist only in the form of gas because of the sun’s ______.

A. size　　　　　　　　 B. age　　　　　　　　 C. location　　　　　　　　 D. temperature

2.With what topic is the second paragraph mainly concerned?

A. How the sun evolved.

B. The structure of the sun.

C. Why scientists study the sun.

D. The distance of the sun from the planets.

3.All of the following are parts of the sun’s atmosphere EXCEPT the _______.

A. corona　　　　　　 B. chromospheres

C. photosphere　　　 D. core

4.According to the passage, as the corona rays reach the planets, they become _______.

A. hotter　　　　　　 B. clearer

C. thinner　　　　　 D. stronger

5.The paragraph following the passage most likely discusses which of the following?

A. The remaining layers of the sun.

B. The evolution of the sun to its present form.

C. The eclipse of February 1979.

D. Scientists will cost more money on researching the corona.

Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core.
