Sunspots

It's not surprising that sunspots (太阳黑子) were observed by ancient astronomers (天文学家). The largest sunspots on the sun can be seen without a telescope. It was not until the invention of the telescope (望远镜) in the early 17th century, however, that systematic studies of sunspots could be undertaken. The great astronomer Galileo was among the first to make telescopic observations of sunspots.

Sunspots are regions of extremely strong magnetic fields (磁场) found on the sun's surface. A sunspot has a dark Central core known as the umbra. The umbra is surrounded by a dark ring called the penumbra, where the magnetic field spreads outward. SunSpots appear dark because they are giving off less radiation. They are cooler than the rest of the sun's surface.

Sunspots are frequently observed in pairs or in paired groups. The members of a spot pair are identified as the leading spot and the following spot. They are identified by their position in the pair in terms of the direction in which the sun rotates (旋转).

The number of sunspots at any one time varies. A large spot group may consist of as many as 10 groups and 300 spots across the sun. The number of spots changes in a fairly regular pattern called the sunspot cycle. The largest number occurs about every 11 years. At sunspot minimum, there are at most just a few small spots.

The average lifetime of an individual spot group is roughly one solar rotation, which is about 25 days. The most persistent large spots,' however, can survive for two to three months.

Careful observations and systematic studies of sunspots

A.were made by ancient astronomers.

B.started in the early 17th century.

C.were made by Galileo only.

D.could be made without a telescope.

If the sun has enough power to warm and light the ...

If the sun has enough power to warm and light the whole earth, it must have enough powerto do other things, too. Can we use the sun’s plentiful energy to supply electricity, or at least toperform. the functions which electricity or other types of power usually perform? The answer isYES.

For example, people have for many years been using the reflected(反射的)heat of the sunto cook. Solar(太阳能的)cookers have been built with several special mirrors reflecting the sunand centering its heat on the cooking part. This equipment can be used just like a gas or electriccooker: it is more expensive to make but it does not need any fuel, and so costs nothing to use. Another possibility of using solar energy is in house heating.

The form. of energy we use must is electricity, and every day more is needed. But electricityalso has to be made, and to make it, huge quantities of fuel are required —oil, coal, gas and soon.

The question which worries everyone today is: how long will these fuels last? Nobodyknows for sure, but most experts think it will soon be difficult to get enough electricity fromthese sources. It is possible that the sun can make a contribution here, too.

Solar power has already been used to produce powerful heat. In Southern France a solarfurnace(锅炉)has been built, where temperatures reach more than 3000℃. This furnace is onlyused for experiments at present, but could be used to produce steam for a power station.

So it is possible that one day in the near future we will depend on solar furnaces and powerstations to provide our electrical needs. Or perhaps each home will be able to use solar power forlighting and heating.

According to Paragraph 1, the sun can provide electricity because ______.

A.it gives us warmth

B.it gives us brightness

C.it has plenty of power

D.it has plenty of gas

One advantage of a solar cooker is that ______.A.no fuel is needed

B.no mirror is needed

C.no heat is needed

D.no space is needed

According to Paragraph 4, most experts think that fuels on the earth ______.A.are always available

B.are limited

C.are expensive

D.are always useful

The underlined sentence in Paragraph 4 means that the sun may provide us with ______.A.enough fuels

B.enough steam

C.enough oil

D.enough electricity

This passage is mainly about ______.A.the problems of solar energy

B.the functions of solar power

C.the use of house heating

D.the forms of energy
