题目内容
Now a row of old houses ________ to make way for new fiats.
[ ]
A. pulls down
B. is pulling down
C. is being pulled down
D. are being pulled down
提示:
|
pull down表示“拆除,拉倒”是固定的动词短语.句首时间状语now表明,该句谓词所表示的是当前正在进行的动作,且主语是谓语动词动作的承受者,应用现在进行时的被动语态.该句主词中心词row为第三人称单数,故答案为C.本句意思是“一排老房子正在被拆除.腾出地盘求盖新公寓”. |
A camera and a computer can “see” something that perhaps millions of pairs of eyes failed to see for 480 years: the Mona Lisa’s necklace. The discovery about the famous painting was made by an American physicist.
The Mona Lisa, painted by the Italian, Leonardo da Vinci, has been on show for many years in Paris. Now a row of white spots on the neck have been “seen”. They are said to be the remains (痕迹) of a necklace which the artist later painted over.
The painting will be examined further by using infrared scanning (红外线扫描) techniques. Laser (激光) technology can be used to show what lies directly under the surface of the finished work, too. This will help us to understand how the artist drew the picture: Did he begin with a quick-made drawing or have second thoughts as he painted the picture?
This kind of knowledge will show us the famous artist at work. It may also help to explain Mona Lisa’s smile, which has puzzled art lovers for centuries.
