下图为某地地质地形剖面图,读图回答:

小题1:海洋中的现代沉积物主要来源于

A.甲处岩石

B.乙处岩石

C.丙处岩石

D.丁处岩石小题2:下列关于岩层形成的先后排序正确的是

A.abcd

B.defg

C.cdba

D.dcba小题3:关于丙丁之间的地质构造的描述正确的是

A.山岭

B.背斜

C.向斜

D.地垒

答案

小题1:C

小题2:D

小题3:C

小题1:因为丁处位于山脉背对海洋的一面,物质(土、石)被冲刷后不会进入海洋。

而甲乙在以前的海拔要比现在高,由于水流长期冲刷,大量地表堆积物已被冲入海洋,形成了沿海平原(甲)和山前倾斜平原(乙)。所以现代沉积物主要来自地势较高、尚未被冲刷完全的丙处。 而且乙处的岩层早就缺少了一层,显然已被冲走了,所以不可能是乙。所以本题选择C选项。

小题2:根据岩层的位置判断,岩层形成的先后排序正确的是dcba。所以本题选择D选项。

小题3:丙丁之间的岩层向下弯曲,所以为向斜。所以本题选择C选项。

     Women have been making scientific discoveries since ancient times. Twelve women have won the Nobel

Prize for science, one of the highest honors in the world. Some women scientists never married, some worked with the ir husbands, and othe rs raised large families. It has been difficult for women to be successful scientists.

     In the early 1800s in England, Mary Anning became one of the first women recognized for her discoveries

time because she often sold her fossils to get money to support her family.

     In 1891, a young Polish woman named Marie Sklodowska traveled to Paris to study physics. She did so

because she could not get a college education in Poland. She began working in the laboratory of a man named

Pierre Curie. Marie and Pierre Curie got married and made many discoveries together. the y received the

Nobel Prize for Physics in 1903 along with anothe r scientist. Marie Curie became the first person to be

awarded a second Nobel Prize in 1911, this time for Chemistry. Marie Curie was one of the few women at the

time who became famous as a scientist.

1. the author believes that women scientists ______.

B. can not get the highest honors in the world

C. go through difficulties to be successful

A. win the Nobel Prize for Science after getting married

C. research animals and the ir bones

D. study the mystery of all kinds of plants

3. Mary Anning failed to be famous for her discoveries of fossils when she was 12 because ______.

A. nobody recognized them

B. the y weren't worth studying

C. she didn't want to be known to anyone

D. she sold the m for money

4. What can we learn about Mary Sklodowska?

A. She studied physics in Poland and got a college education.

B. She received the Nobel Prize for Physics in 1903 on her own.

C. She only got one Nobel Prize during her lifetime.

D. She made many discoveries after she got married.

5. What's the passage mainly about?
