【题目】贵州矿产资源丰富，煤、铝土等主要矿种优势显著。西部大开发十几年来，贵州已成为我国重要的矿产基地之一，但环境问题也日益突出。据此完成下列各题。

【1】贵州采矿工业导致环境问题严重的原因可能是( )

A．露天矿表土剥离易造成严重的土地沙漠化

B．矿区道路铺设极易造成严重的水污染

C．重化工业体系多高耗高排产业，环境污染严重

A．①② B．③④ C．①③ D．②④

【答案】

【1】C

【2】D

【解析】

试题分析：

【1】贵州降水多，露天矿表土剥离易造成严重的水土流失，矿区道路铺设常用采矿的废料，可能加重水污染，但不是水污染的主要原因，煤化工、有色金属冶炼多高耗高排产业，环境污染严重，燃煤发电、洗煤、炼煤、炼焦等工业的发展极易造成环境污染，不是生态退化。

【2】贵州缺少铁矿，不适合构建煤—电—钢产业链，贵州煤炭丰富，适宜发展煤—焦—化产业链，贵州缺少天燃气资源，不适宜煤—气—液产业链，贵州煤、铝土丰富，适宜煤—电—铝产业链，所以D正确。

【题目】阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.

It has been several weeks since we took our daughter to college and she seems to be adjusting well after a short period of homesickness. For us, though, it’s another story. Like most parents, I love checking in on my children at night. But now she’s gone, and I find night times the hardest. I miss her most at night.

In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. We complained that many of us were too busy to truly enjoy being with our children while we had them.

For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it’s not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn’t get any easier.

As I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think at messages serve as a night light that keeps her safe.

A. She watched the scene with her daughter.

B. The scene was very exciting and interesting.

C. The scene taught her and her daughter a good lesson.

【2】After her daughter went to college, the writer ________.

A. didn’t get used to the change for a long time

B. often cried as she missed her daughter so much

C. realized she hadn’t done enough for her daughter

D. failed to have a good sleep every night

【3】What is the underlined word “melancholy” in Paragraph 3 similar in meaning to?

A. Happiness. B. Anger.
