问题 单项选择题

海洋中珊瑚的美丽颜色来自于其体内与之共存的藻类生物,其中虫黄藻是最重要的一类单细胞海藻。二者各取所需,想互提供食物。全球气候变暖造成的海水升温导致虫黄藻等藻类大量死亡,进而造成珊瑚本身死亡,引发珊瑚礁白化现象,然而研究发现,珊瑚能通过选择耐热的其他藻类生物等途径,来应对气候变暖带来的挑战。以下哪项如果为真,将削弱这一研究发现?( )

A.一些虫黄藻能够比耐热的其他藻类耐受更高的海水温度

B.有些藻类耐热性的形成需要一个长期的过程

C.有些虫黄藻逐渐适应了海水温度的升高并存活下来

D.有些已白化的珊瑚礁中也发现了死去的耐热藻类生物

答案

参考答案:A

解析:【解析】A。因为一些虫黄藻比其他藻类更耐热,所以珊瑚礁就不用再选择其他藻类,削弱了题干的论断,所以A项削弱了研究发现

A man accused of failing to return more than 700 children’s books to five different libraries in the county was released from prison after a book publisher agreed to post his bond (保释金) of $1,000. The publisher said, “There’s a story here. This is a man who loves books. He just can’t let go of them. He hasn’t stolen a single book. So what’s the crime? We think that Mr Barush has a story to tell. We plan to publish his story.”

When asked why he didn’t return the books, Mr Barush said, “Well, how could I? They became family to me. I was afraid to return them, because I knew that kids or dogs would get hold of these books and chew them up, throw them around, tear the pages, spill soda on them, get jam and jelly on them, and drown them in the toilet.”

He continued, “Books are people, too! They talk to you, they take care of you, and they enrich you with wisdom, humor and love. A book is a guest in my home. How could I kick it out? I repaired torn pages. I dusted them with a soft clean cloth. I turned their pages so they could breathe and get some fresh air.”

“Every week I reorganized them on their shelves so they could meet new friends. My books were HAPPY books. You could tell just by looking at them. Now they’re all back in the library, on the lower shelves, on the floors, at the mercy of all those runny-nosed kids. I can hear them calling me! I need to rescue them. Excuse me. I have to go now.”
