质量相同的木球和蜡块放入水中静止后均浮在水面,其中木球露出水面的体积较大,则它们所受浮力关系为(  )

A.木球受浮力较大

B.蜡块受浮力较大

C.木球和蜡块受浮力一样大

D.无法判断

答案

由于两物体的质量相等,据公式G=mg可知,蜡块的重力等于木球的重力;

由于两物体均漂浮,所以F=G;由于蜡块的重力等于木球的重力,所以蜡块所受的浮力等于木球所受的浮力;

故选C.

I left university with a good degree in English Literature, but no sense of what I wanted to do. Over the next six years, I was treading(在...上面走) water, just trying to earn an income. I tried journalism, but I didn’t think I was any good, then finance, which I hated. Finally, I got a job as a rights assistant at a famous publisher. I loved working with books, although the job that I did was dull.

I had enough savings to take a year off work, and I decided to try to satisfy a deep-down wish to write a novel. Attending a Novel Writing MA course gave me the structure I needed to write my first 55,000 words.

It takes confidence to make a new start — here’s a dark period in-between where you’re neither one thing nor the other. You’re out for dinner and people ask what you do, and you’re too ashamed to say, “Well, I’m writing a novel, but I’m not quite sure if I’m going to get there.” My confidence dived. Believing my novel could not be published, I put it aside.

Then I met an agent(代理商)who said I should send my novel out to agents. So, I did and, to my surprise, got some wonderful feedback. I felt a little hope that I might actually become a published writer and, after signing with an agent, I finished the second half of the novel.

The next problem was finding a publisher. After two-and-a-half years of no income, just waiting and wondering, a publisher offered me a book deal — that publisher turned out to be the one I once worked for.

It feels like an unbelievable stroke of luck — of fate, really. When you set out to do something different, there’s no end in sight, so to find myself in a position where I now have my own name on a contract(合同)of the publisher — to be a published writer — is unbelievably rewarding.
