試題分析:句意:--媽媽,我能看會(huì)兒電視嗎?--一旦你的作業(yè)寫完了,你就可以看電視了。作業(yè)是動(dòng)作的承受者,所以用被動(dòng)語態(tài),在條件狀語從句中,如果兩個(gè)動(dòng)作都沒有發(fā)生,為了區(qū)別動(dòng)作的前后關(guān)系,先發(fā)生的用一般現(xiàn)在時(shí)態(tài),后發(fā)生的用一般將來時(shí)態(tài),即主將從現(xiàn)。作業(yè)被完成是從句,故用一般現(xiàn)在時(shí),故選C.

考點(diǎn):考查一般現(xiàn)在時(shí)的被動(dòng)語態(tài)。

What do people do with their old, out of date but still useful computers? Most people don’t know how to deal with them. Many old computers are put away. Many more are simply thrown away as rubbish.

Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products(產(chǎn)品). Dell, Hewlett Packard and other companies now also take back some old computers of their own brands.

In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升級(jí)).

Yet many people are throwing away good computers, while others cannot afford them at all. Hundreds of organizations are working on this problem. They collect and repair old computers. Some also teach others how to repair computers. These repaired computers then go to schools, charities(慈善團(tuán)體) or people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things and cut down waste, too.
