【題目】下列河流中，注入北冰洋的是（　�。�

A.額爾齊斯河B.怒江

C.黑龍江D.長(zhǎng)江

【答案】A

【解析】

根據(jù)中國(guó)外流區(qū)面積610多萬(wàn)平方千米，約占全國(guó)陸地總面積的64%；內(nèi)流區(qū)面積約占全國(guó)陸地總面積的36%；中國(guó)絕大多數(shù)河流分布在外流區(qū)，外流河年徑流總量占全國(guó)的95%以上，內(nèi)流河年徑流總量不足5%，進(jìn)行分析解答。

河流是地形和氣候的產(chǎn)物。我國(guó)受地勢(shì)的影響大部分河流滾滾東流，如長(zhǎng)江、黃河自西向東注入太平洋；只有西南部的雅魯藏布江和怒江轉(zhuǎn)向西南注入印度洋，新疆北部的額爾齊斯河流向北穿越中亞北亞最后注入北冰洋，也是我國(guó)唯一一條注入北冰洋的河流。故選：A。

【題目】

You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it's not! In fact, the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table. Your brain controls everything that you need to do to save that glass from falling. First your eyes check out what's going on, then tell your brain, and your brain decides how quickly you need to react(反應(yīng)), and then your muscles(肌肉) go into action. That is just from your brain. No computer could ever come close to that!

The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ(器官). There are about 100 billion tiny, tiny little cells(細(xì)胞) in your brain. There are so many that it would take you over 3, 000 years to count them all!

Your brain stops growing when you're 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won't be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for longterm memory establishment. It is realized that the brain is the second organ in the body as the heart that never stops during human lives.

So everyone should be proud of such a gift of nature.

A.eyes and muscles react quickly

【3】In which magazine can the passage be found most probably?

A.Business WeeklyB.MedicineC.ScienceD.Sports

A.儲(chǔ)存B.形成C.空缺D.建立
