Computers can help you do your homework in all kinds of ways. They can even make it easy to write the following sentence one hundred times:“I will not be late again.”All you have to do is to write a simple problem, run it, and print out the results.
Of course, there are better ways to use a computer to help do your homework. The lesson can be in the form of a new learning experience, a drill, or a review. And you can do the lessons as many times as you want—a computer never gets bored.
All kinds of computer programs are being used as learning tools. For example, people are learning to type rapidly with typing programs. You can immediately tell how well you are doing and even have fun while practising.
The most popular use of a computer to help with homework is with a word processing program. A word processor lets you type on a keyboard(键盘) and see the words on a screen in front of you. You never have to retype a whole page to correct a few mistakes. A word processor allows you to make changes and corrections quickly and easily. It allows you to arrange sentences, paragraphs, and even pages of material. It lets you think about what you are writing without worrying too much about keeping them neat and tidy. Then when you want what you have written, all you need to do is to push a key and your poem, story, or essay is printed. In fact, the words you are reading now were first written on a word processor.

查看习题详情和答案>>A metaphor is a poetic device that deals with comparison. It compares similar qualities of two dissimilar objects. With a simple metaphor, one object becomes the other: Love is a rose. Although this does not sound like a particularly rich image, a metaphor can communicate so much about a particular image that poets use them more than any other type of figurative language. The reason for this is that poets compose their poetry to express what they are experiencing emotionally at that moment. Consequently, what the poet imagines love to be may or may not be our understanding of love. Therefore, the poet’s job is to enable us to experience it, to feel it the same way as the poet does.
Let’s analyze this remarkably simple metaphor concerning love and the rose to see what it offers. Because the poet uses a comparison with a rose, first we must examine the characteristics of that flower. A rose is impressive in its beauty, its petals(花瓣)are nicely soft, and its smell is pleasing. It’s possible to say that a rose is actually a feast to the senses of sight, touch, and smell. The rose’s appearance seems to border on perfection, each petal seemingly equal in form. Isn’t this the way one’s love should be?A loved one should be a delight to one’s senses and seem perfect.
However, there is another dimension added to the comparison by using a rose. Roses have thorns. The poet wants to convey the idea that roses can be tricky. So can love, the metaphor tells us. When one reaches out with absolute trust to touch the object of his or her affection, ouch, a thorn can cause great harm! “Be careful,” the metaphor warns, “Love is a feast to the senses, but it can overwhelm us, and it can also hurt us and cause acute suffering.” This is the poet’s understanding of love—an admonition (劝诫). What is the point?Just this: It took almost 14 sentences to clarify what a simple metaphor communicates in only four words! That is the artistry and the joy of the simple metaphor.

A. description of two similar objects in a poetic way

2.As is meant by the author, thorns of a rose ________.
A. add a new element to the image of love

D. cause acute suffering
3.It can be inferred from the passage that a metaphor is _______.
A. difficult to understand B. rich in meaning
C. simple to use D. perfect in form

A. love is a rose in metaphor
