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.

1.The underlined word “hazardous” in Paragraph l most probably means________．

2.The author seems to tell us in Paragraph 2 that________．

3.Yon should prepare your food away from where you sleep so that________．

5.Which of the following is the main idea of this passage?

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!

A week ago, I had the great pleasure of reading an e-book, When Money Talks, Listen! By Rich Ezzo．It took only about an hour to read.

   When I first received a copy, I thought it was a Get Rich Quick type of publication．Nothing is wrong with Get Rich Quick, but my mind just doesn’t chase after dreams of wealth．I think that if God ever wants me to be rich, he knows where to find my purse.

   When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either．He, too, is hungry far more important than money．

Since I love this e-book so much, why wait a week to write the review? Simple．I wanted to see if the effect it had on me was a keeper．After reading the last word of the e-book, I totally agreed with the subtitle which promised to forever change the way we thought about money．I had so many thoughts running around my mind that I had to install(安装) a stoplight to stop some while others made their way into the picture, then I yielded(让路) them as a few ones arrived in town．I had a mental traffic jam, which only goes to show how slow the traffic usually is．

   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.”

If you look for a book as a present for a child. You will be spoiled for choice even in a year there is no new Harry Patten J.K Powling’s wizard is not alone the past decade has been a harvest for good children’s books, which has set off a large quantity of films and an increased sales of classics such as The lard of the Rings.

Yet despite that , reading is increasingly unpopular among children. According to statistics in 1997 23% said they didn’t like reading in all. In 2003, 35% did . And around 6% of children leave primary school each year unable to read properly.

Maybe the decline is caused by the increasing availability of computes games. Maybe the books boom has affected only the top of the educational pile. Either way, Chancellor Cordon Brown plans to change things for the bottom of the class. In his pre-budget report, he announced the national project of Reading Recovery to help the children struggling most.

Reading Recovery is wined at six year olds, who receive four months of individual daily half-hour classes with a specially trained teacher. An evaluation either this year reported that children on the school made 20 months’ progress in just one year, whereas similarly weak readers without special help made just five months’ progress, and so ended the year even further below the level expected for their age.    

International research tends to find that when British children leave primacy school they read well, but read text often for fun than those elsewhere. Reading for fun matters because children who are been on reading can report lifelong pleasure and loving books is an excellent indicator of future educational success. According to the OECD, being a regular and enthusiastic reader is of great advantage

B. a decreasing number of children showed interest in reading

C. a minority of primacy school children read properly

D. a huge percentage of children read regularly

What do we know about Reading Recovery?

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

       B．the blind woman needed the money badly

       C．the author was as poor as the blind woman

       D．the author was a native American
