读“岩石圈物质循环示意图”,回答14~15题:

小题1:下列叙述正确的是(  )

A.d为变质岩

B.a为沉积岩

C.c为岩浆岩

D.b为变质岩小题2:下列数码对应的地质作用正确的是(  )

A.⑤外力作用

B.⑥变质作用

C.③重熔再生作用

D.①冷却凝固

答案

小题1:A

小题2:D

小题1:地球内部的岩浆,经过冷却凝固形成岩浆岩,岩浆岩受流水、风、冰川、海浪等的侵蚀、搬运、堆积作用,形成沉积岩。同时,这些已生成的岩石,在一定温度和压力等作用下发生变质,形成变质岩。各类岩石在地壳深处或地壳以下发生重熔再生作用,又成为新的岩浆。所以a为侵入型岩浆岩,b为喷出型岩浆岩,c为沉积岩,d为变质岩。所以本题选择A选项。

小题2:①为岩浆的上升冷却凝固;③为外力作用,⑤为变质作用,⑥为重熔再生。所以本题选择D选项。

     During my high school years, the most important thing was what I was wearing to the Friday night

dance and who I was taking.Although college was talked about, it was the least of my worries.

     When I was graduating eighth grade and starting high school, my older brother was graduating twelfth

grade and going onto college.For my graduation, he gave me a card in which he wrote, "Enjoy your four

years...They go by fast." I remember not believing him then, but looking back...He was right.Those four

years shaped who I was as a person, pushed me to my limit and encouraged me to become an adult.

     However, I was so completely absorbed in my junior and senior years of high school, that when

someone spoke of college I brushed it off.I wasn't ready to leave my comfort zone of having all of my

closest friends together and knowing what every single day was going to be like.Studying was something

I did only AFTER I nailed my halftime dance performance.I knew my parents wanted me to go to

college, so I told them I would go to community college (社区学院) and I didn't worry about my SAT

(美国大学入学考试) scores.

     When my senior year passed and everyone graduated and went off to their own colleges, I started to

wish I had done the same.My friends were living away, meeting new people, and discovering new places, while I was living at home and driving to and from class every day.It seemed exactly like high school.I

hated it!I thought college was supposed to be different!Why didn't I take more time to research colleges

and do the same?I ended up loving college and wishing I had four years to enjoy the campus (大学校

园) atmosphere instead of two.

     My advice to anyone thinking about attending college is to think about it very seriously and look into

all of your choices well ahead of time.Now I have graduated and I am working fulltime and I would do

anything to go back to my high school days for a second chance!
