题目列表(包括答案和解析)

Even if you are an experienced backpacker or climber,you need to know what to do if something goes wrong.It is not that Alaska is that much more dangerous than other places.It is no more hazardous than elsewhere,as long as the proper precautions(预防措施)are taken.So, being prepared is crucial to ensure a safe trip.

First of all,make sure you pack everything you will need for your trip.Even if you are traveling by car,pack clothes and gear for backpacking.Because of the bad weather, cars break down frequently. Pack a survival(生存)kit full with:a down coat, boots ,mittens, a hat, snow-pants,sleeping bags,candles,a flashlight,and high-energy food. If you are traveling by car , also pack extra belts, a shovel, and a chain.

If you are camping or hiking,make sure you know how to avoid bears.If you are lost in the wilderness, there is no doubt you will encounter them.

However,there is no need to be nervous.Just take these precautions:make noise as you walk,bears will avoid you;cook your food away from where you sleep,and store your food away from where you sleep,so the bears are not attracted.Both of these should keep the bear away.However,if you do encounter a bear,there are two different schools of thought.One is to make noise and scare the bear away.The other is to stand still and speak softly to get the bear to leave.If you are dealing with a brown bear,you can climb a tree,since it cannot follow.But,black bears can climb.If for some reason the bear attacks,play dead.Try to protect your head and neck,and hopefully the bear will leave its“dead” prey.

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

After the explosion gravity pulls in what’s left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.

The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

That’s what we know about black holes. What we don’t know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

But if the black hole doesn’t keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world.They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly — somewhere else. But where? A different place, perhaps, or a different time — many years in the past or future.

Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed.So far the time being, black hole must remain a mystery.

Black holes are a mystery—but that hasn’t stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth’s energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste—a sort of huge waste disposal (处理) in the sky!

When the star begins to die ______.

       A.there is no fuel left in it B.its outer layer goes into space first

       C.a huge explosion will happen        D.it doesn’t give off light any longer

Which of the following doesn’t help produce a black hole?

       A.The gravity inside the star is very strong.

       B.The light can’t go out of the star.

       C.The star becomes smaller and smaller

       D.The dying star shines very brightly.

The black hole ______.

       A.continues becoming smaller and smaller all the time

       B.goes into another universe and becomes a white hole

       C.can pull in everything we know of in the world

       D.will appear at another place at a different time

What’s the best title for this passage?

       A.A New Scientific Discovery: Black Holes

       B.How Do Black Holes Come Into Being?

       C.What Are Black Holes?

       D.Travel Through A Black Hole

   It has been a week and the effect is the same.I truly do look at money differently and have even done a few things differently this week.This is an e-book you’ll want to read, I promise.I often recommend books to my daughter, and this is one that I didn’t just “suggest”---I left it open at the bottom of the computer and told each one, “Read it, you’ll love it.”

A few years ago, I took a sightseeing trip to Washington, D.C.Standing outside the Ronald Reagan Center, I heard a voice say, “Can you help me?” When I turned around, I saw an elderly blind woman with her hand extended.In a natural reflex (反应), I reached into my pocket, pulled out all of my loose change and placed it on her hand without even looking at her.I was annoyed at being bothered by a beggar.But the blind woman smiled and said, “I don’t want your money.I just need help finding the post office.”

     In an instant, I realized what I had done.I judged another person simply for what I assumed she had to be.I hated what I saw in myself.This incident re-awakened my belief in humility(谦恭), even though I’d lost it for a moment.

     The thing I had forgotten about myself is that I am an immigrant.I left Honduras and arrived in the U.S.at the age of 15.I started my new life with two suitcases, my brother and sister, and a strong, serious-minded mother.Through the years, I have been a dishwasher, mechanic and pizza delivery driver among many other humble jobs, and eventually I became a network engineer.

     In my own life, I have experienced many open acts of prejudice (偏见).I remember a time, at age 17 ----- I worked as a waiter, and I heard a father tell his little boy that if he did not do well in school, he would end up like me.I have also witnessed the same treatment of my family and friends, so I know what it’s like, and I should have known better.

     But now, living in my American middle-class lifestyle, it is too easy to forget my past, to forget who I am and where I have been, and to lose sight of where I want to be going.That blind woman on the streets of Washington, D.C., cured me of my blindness.She reminded me of my belief in humility and to always keep my eyes and heart open.By the way, I helped that lady to the post office.And in writing this essay, I hope to thank her for the priceless lesson.

We can learn from the first two paragraphs that __________ .

       A.the author regretted his act of prejudice

       C.the author was as poor as the blind woman
