As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that.

Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere.

A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy.

Boaz Leupe, CEO of the start-up Nerdalize, says it’s actually quite simple.

"We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe.

The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes.

“We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center,” says Leupe.

One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server’s processors so it cannot be used as the primary source. But he is ready to try it.

“If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills.”

Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in annual heating costs.

Perhaps the most challenging material you read at school is poetry. Though the message of some poems may be very simple, the way poets put words together often makes this message elusive. When you read a poem, you should begin by trying to understand what the poet is saying on the surface, then examine the way the poet expresses this content, and finally decide how the poem's meaning is created. Here are some steps to read a poem.

First, read the poem once slowly aloud without writing or marking anything. Don't stop until you finish the poem, even if you don't know the meaning or pronunciation of a word. When you've finished, think it over for a moment on any words, images, and characters that caught your attention. Then read the poem again silently. When you come to a word you don't know, look it up in the dictionary.

Understand the meaning of figurative (比喻的)language. Figurative language doesn't mean exactly what it says; instead, it suggests meanings. For example, in the line “Love, all alike, no season knows”, the poet doesn't mean love is unfamiliar with four seasons. Love cannot know anything at all; only people can know something. Thus, the poet is personifying(拟人化) love, giving it human qualities.

Examine and think about the poet's use of language. Why, for example, did the poet choose to compare his love to a red rose instead of a tree or a bird? We can use associations: we usually associate roses with beauty and love, but we also know a rose bush has thorns (刺). All of these associations may not be right for a particular poem, but many of them probably will.

Finally, read the poem one more time aloud.Practice using pauses and stress to make the poem's meaning come alive.

1.The underlined word “elusive” in Paragraph 1 probably means “________”.

A.easy B. interesting

C.difficult D. boring

2.What should we put on the first place when reading a poem?

A.The form of the poem.

B.The content of the poem.

C.The meaning of the poem.

D.The language of the poem.

3.When reading a poem for the first time, we should________.

A.try to understand new words

B.examine the poem's language

C.try to understand its meaning well

D.avoid being stopped by new words

4.We can learn from the passage that figurative language________.

A.is useful in expressing love

B.helps us understand new ideas

C.is easy for most readers to understand

D.should be repeated while reading a poem
