问题 单项选择题

科学家才刚刚开始了解深海生物的多样性和重要性以及深海生态的脆弱性。目前,研究人员对深海环境和物种的研究范围还太小。据估计,仅有不到1%的海底山得到探索。因而科学家最大的担忧是,在对深海进行全面的环境和物种研究之前,深海生态系统已被人类大杀伤力的海底拖网捕捞摧毁,大量物种因此灭绝,那么,人类将永远失去了解地球生物多样性的机会,从而失去可以依赖的最大资源。
本段文字意在说明( )。

A.人类对深海生态系统的破坏会导致物种灭绝
B.深海生物的多样性和重要性才刚刚开始被了解
C.科学家对深海生态系统遭到破坏的担忧不无道理
D.在对深海进行全面的研究之前,人类不应该一味破坏深海生态系统

答案

参考答案:D

解析: 根据文段含义,人类对深海环境和物种的研究才刚刚开始,而人类的破坏将导致大量物种灭绝,人类也会因此而失去了解地球生物多样性的机会,从而失去可以依赖的最大资源。故文段意在说明,在对深海进行全面研究之前,人类不应该一味破坏深海生态系统,因此D项正确。A项说法过于绝对,B项不是文段意在强调的内容,C项不如D项意图明显且不是重点。故本题选D。

One Sunday, a picture in the newspaper touched me. A young woman stood in front of a totally destroyed home. A little boy stood beside her with his head    . Holding her skirt tightly was a tiny girl, eyes wide with        and fear.
With growing       I noticed that their sizes of each family member closely      ours. This would be a good opportunity to    my children, so I explained their difficult    to my seven-year-old twins and three-year-old Meghan.
“We have so much, but these poor people now have nothing,” I said, “we’ll      what we have with them.”
I brought three large boxes and placed them on the living room floor. Meghan watched seriously      the boys and I filled one box with canned food.
While I     our clothes, I encouraged the boys to go through their toys and     some of their less favorite things. Meghan watched      as the boys piled up useless toys in the box.
“I’ll help you find something for the little girl,” I said to her.
The boys placed the toys they had     to donate into one of the boxes while I filled the third box with clothes. Meghan walked up with Lucy, her worn, faded, much-loved doll    tightly to her chest. She      in front of the box, pressed her little face into Lucy’s face, gave her a      kiss, then, laid her gently on top of the other toys.
“Oh, honey,” I said. “You      to give away Lucy. You love her so much.”
Meghan nodded, eyes shining with tears. “Lucy makes me happy, Mommy.       she’ll make that little girl happy, too.”
I stared at Meghan for a long moment,        how I could teach the boys the lesson she had just taught me.
It’s easy to give what we don’t want any more, but       to let go of things we cherish, isn’ t it?       , the true spirit of giving is to give with your heart.
