Leonardo da Vinci began painting the Mona Lisa in 1503. He was working on an important painting for a church at the time, but the church painting was not going well. An Italian businessman asked da Vinci to paint a picture of the businessman’s second wife. This is the woman who can be seen in the Mona Lisa.

All in all, the Mona Lisa is a very good example of da Vinci’s work. Da Vinci uses darkness and light in a clever way in the painting.

Da Vinci loved science and math. Right away a person can see that there is a lot of geometry (几何) in the Mona Lisa. The face of Mona Lisa is made of many circles and round shapes like balls. Even her smile can be seen as a small part of a large circle.

The woman in the painting is sitting on a balcony, and mountains can be seen behind her. Da Vinci loved to study rocks and mountains, so these can be seen over and over again in his other paintings.

The woman is sitting with her knees to the side. Her head is turned to look out of the painting. Her hands are held together in front of her. This way of sitting is now used by many artists when they are painting a picture of a man or woman today.

小题1:Who painted the Mona Lisa?

A.A businessman.

B.The second wife.

C.A man in the church.

D.Da Vinci.小题2:The woman in the painting is           .

A.standing in a garden

B.sitting on a balcony

C.standing in front of her house

D.at the foot of a mountain小题3:Da Vinci loved to study all of the following things except            .

A.the way people sit

B.science and math

C.mountains

D.rocks

答案

小题1:D

小题2:B

小题3:A

题目分析:文章描述了达・芬奇的名画《蒙娜丽莎》的由来以及其中的一些细节,并从专业与大众的角度对该画以及该画的影响做了诠释.  

小题1:根据Leonardo da Vinci began painting the Mona Lisa in 1503可知,达芬奇画的《蒙娜丽莎》。所以本题选D。

小题2:根据The woman in the painting is sitting on a balcony一句可知,本题应该选B。

小题3:根据Da Vinci loved science and math.和Da Vinci loved to study rocks and mountains可知,达芬奇喜欢BCD中列举的事物,故A是他不喜欢的。所以本题选A。

点评:本文的意思比较好理解,虽然其中出现了许多生词,但并不影响对文章的理解;本题设计的三个题目在文中都能找到相应的句型,不需要进行推断,所以也比较容易。

A.升高温度正反应速率减慢,逆反应速率加快

B.当3v(H2)=v(CO2)时,该反应达到了平衡状态

C.将H2O(g)从体系中分离出来,可提高CO2和H2的转化率

D.再充入1molCO2和3molH2,可使n(CH3OH)/n(CO2)增大
