"Shark on the bait （诱饵） !" shouted Andre Harman, pointing to a spot a few yards behind the outboard motors． His voice gave no indication of panic, but the crew suddenly became tense and fixed their eyes on the water． Slowly, smoothly, Andre drew in the bait．The shark followed． No one asked what kind of shark it was． Everything about it, from its color to its shape, tells that it was a great white shark．
Andre lifted the bait aboard． Placing himself between the two motors, he dropped his right hand into the water just as the great head reached the first motor．“My goodness Andre!” I said． His hand seized the big nose, moving it away from the tube of the motor, guiding the shark's head up as it rose out of the water． Andre's hand held the nose, touching it gently． No one spoke． No one breathed． The moment seemed endless． In fact, it lasted less than five seconds before Andre pulled his hand back．
Still nobody spoke． Then Andre smiled and said: "The first time was an accident． I was just trying to move the shark away from the motor． Sharks are attracted to motors by r．heir electrical signals and have a habit of biting them to see if they are eatable． " Andre has worked with great white sharks for years． "My hand landed on its nose, and it sort of paused, so I kept it there, and when I did let go, the shark bit and bit as if it was searching for whatever it was that had attracted it．"
Nearly every encounter （遭遇） we had had with the great whites had been totally illogical． The more we learned, the more we realized how little was really known about them in the past years． Back then, it was generally accepted that great whites ate people by choice． Now we know that almost every attack on a human is an accident in which the shark mistakes a human for its normal food． Back then, we thought that once a great white smelt blood, it would lead to death． Now we know that nearly three-quarters of bite victims survive, perhaps because the shark recognizes that is has made a mistake and doesn't return for a second bite．

The latest fashion in kitchen is the food steamer． All the stores are selling them; everyone wants one． Steaming is one of the simplest and healthiest ways of cooking food．However, that cooking time is usually longer than with other methods． In case you’re thinking of buying a steamer, I've done a survey about the steamers available on the market to help you decide which will suit you best．
●Folding Steamer
The simplest and least expensive is the folding stainless-steel （不锈钢）version．
Advantages: This is a good, basic design which sits inside a variety of different shapes of pans with the water under it; a ring in the center allows for easy lifting and it's easy to clean．
Disadvantages: It only holds small dishes． Also, if you put too much water in the pan, it will boil up through the vegetables and they will be watery． If you put too little water in and let it get dry, you will burn the pan and get strange-smelling vegetables．
●Steaming Pan
This is a three-layered black Teflon-coated version with a lid and two double-handled steamers, which sits on the oven ring． The brand I bought is called Nutritious Living．
Advantages: This is an excellent steamer, lightweight, easy to clean, and of all the steamers I've tried, this cooks the fastest． Fish and chicken can be cooked on the bottom with rice or vegetables on the top． It's easier to store．
Disadvantages: Water can boil away until the pan is dry, but if you make sure you fill the pan up to the suggested level and do not overcook the food, this should not happen．You cannot see the food cooking from the top． It doesn't supply a dish for cooking rice．
For serious users of steamers, I recommend having one of each version． If you just want to try it, get the folding stainless-steel type．

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.
Since 1960 a new kind of tool has appeared. This is the silicon chip (硅芯片). It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it?
Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?

High school dropouts(辍学者)earn an average of ＄9000 less per year than graduates．Now a new study dispels a common belief why they quit．It’s much more basic than flunking out(不及格)．
Society tends to think of high school dropouts as kids who just can’t cut it．They are lazy, and perhaps not too bright．So researchers were surprised when they asked more than 450 kids who quit school about why they left．
“The vast majority actually had passing grades and they were confident that they could have graduated from high school, ” John Bridgeland, the executive researcher said．About 1 million teens leave school each year．Only about half of African-American and Hispanic(美籍西班牙的)student will receive a diploma(证书), and actually all dropouts come to regret their decision．So, if failing grades don’t explain why these kids quit, what does?Again, John Bridgeland：“The most dependable finding was that they were bored．”“They found classes uninteresting; they weren’t inspired or motivated．They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations．”
The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit．In the US, only one state, New Mexico, has a law requiring teenagers to stay in high school until they graduate．Only four states：California, Tennessee, Texas and Utah, plus the District of Columbia, require school ?attendance? until age 18, no exceptions, another researcher, says raising the compulsory(义务的)attendance age may be one way to keep more kids in school．
“As these dropouts look black, they realize they’ve made a mistake．And anything that sort of gives these people an extra push to stick it out and it through to the end, is probably helpful measure．”
New Hampshire may be the next state to raise its school attendance age to 18．But critics say that forcing the students unwilling to continue their studies to stay in school misses the point－the need for reform．It’s been called for to reinvent(彻底改造)high school education to make it more challenging and relevant(中肯的, 切题的), and to ensure that kids who do stick it out receive a diploma that actually means something．
12. Most high school students drop out of school because ________．

A．they have failing grades

B．they take no interest in classes

C．they are discriminated against

D．they are lazy and not intelligent

13. According to the passage, which state has a law requiring school attendance until they graduate?

House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country.     16    

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning.    17     I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

    18     There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time.    19     You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the house owners have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

    20     Then you can travel to many different countries and stay there. One of the important things to get is references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to possible house sitting jobs and they know you will do a good job.

A．I have done house sitting many times.

B．Thousands of people do this all the time.

C．It is also possible to do house sitting in other countries.

D．Generally you have many opportunities to get a house sitting job.

E．You must take a little care over what your description says about you.

F．This is an international house sitting service for all city and country areas.

G．You must have a good car, so you can travel to different parts of the country.
