    Do you know some great inventors and their inventions?

    What factors (因素) are needed for their success?

    Well, good timing for a start. You can have a great idea which the public simply doesn't want … yet. The Italian Giovanni Caselli invented the first fax(传真)machine in the 1860s. Although the quality is excellent, his invention quickly died a commercial(商业的) death. It was not until the 1980s that the fax became very common in every office… too late for Giovanni Caselli.

    Money also helps. The Frenchman Denis Papin (1647-1712) had the idea for a steam engine (蒸汽机)almost a hundred years before the better-remembered Scotsman James Watt was even born… but he never had enough money to build one.

    You also need to be patient (it took scientists nearly eighty years to develop a light bulb which actually worked)… but not too patient. In the 1870s, Elisha Gray, a professional inventor from Chicago, developed plans for a telephone. Gray saw it as no more than “a beautiful toy”. However, when he finally sent details of his invention to the Patent Office(专利局) in February,1876, it was too late. Almost the same invention had arrived two hours earlier and the young man who sent it , Alexander Graham Bell, will always be remembered as the inventor of the telephone.

    Of course what you really need is a great idea—but if you haven't got one, a walk in the country and a careful look at nature can help. The Swiss scientist, George de Mestral, had the idea for Velcro(魔术贴) when he found his clothes covered in sticky seed pods after a walk in the country. During a similar walk in the French countryside some 250 years earlier, Rene Antoine Ferchault de Reaumur had the idea that paper could be made from wood when he found an abandoned wasps' nest(蜂巢).

    You also need good commercial sense. Willy Higinbotham was a scientist doing nuclear (核能的)research in the Brookhaven National Laboratory in Upton, USA. In 1958 the public were invited to an exhibition in the Laboratory to see their work, but both parents and children were more interested in a tiny 120cm screen with a white dot which could be hit back and forth over a “net” using a button and a knob. Soon hundreds of people were ignoring the other exhibits to play the first ever computer game—made from a simple laboratory instrument called an “oscilloscope”. Higinbotham, however, never made money from his invention: he thought people were only interested in the game because the other exhibits were so boring!

(1)、How many factors do inventors need?
A、3. B、4. C、5. D、6.
(2)、The word “ignoring” in last paragraph probably mean?
A、having no idea of B、making no sense to C、getting no chance of D、paying no attention to
(3)、What can you learn from the passage?
A、Giovanni Caselli invented the first fax machine in the 1980s. B、Denis Papin afforded to build a steam engine a hundred years ago. C、Elisha Gray missed the chance to be the inventor of the telephone. D、George de Mestral got the idea from a walk in a French countryside.
(4)、What is the best title for the passage?
A、How to be a successful inventor. B、How to get a great idea from nature. C、How to have good commercial sense. D、How to make money from inventions.

      Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
      Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
     When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don't have enough time to spend taking care of everything yourself, dome helpers may be the best choice.
      After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides(农药) or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence(围栏) or a gate so that only you and your workers can get in and out.
     Mushroom growing is not difficult and it is easy to get stared in the world of farming. You will soon possibly be able to provide some of the great cooks of the world with high quality mushrooms that will be enjoyed by thousands of people all over the world.

    We choose food to eat every day.We might know some of the reasons for the choices,but food scientist Dr.

    Brian Wansink has found that we are unaware of 90% of our food decision.Here are some"big ideas"in his research on the hidden power that drives our eating.

    Food for thought

    In one of the studies,Dr.Wansink made volunteers eat chocolate yogurt in a dark room.He told them the yogurt was with a taste of strawberry even though they were all eating chocolate.Finally,65% of volunteers described the yogurt as having a"nice strawberry flavor!"

    The research shows that our imagination has an effect on our taste.If you expect a food to taste good,it will.So take a moment before you eat your unpleasant healthy food to remind yourself that you are eating delicious fish and chips.

    Our eyes eat first

    How your food looks is just as important as how it tastes.Dr.Wansink gave cakes to three groups of people.The cakes were exactly the same but served in different ways.

①Group one got the cake on a nice plate.

    ②Group two got the cake on a paper plate.

    ③Group three got the cake on a piece of paper.

    Dr.Wansink then asked the people how much they would pay for each cake.

    Dr.Wansink then asked the people how much they would pay for each cake.

    ①Group one who got the cake on a nice plate would pay $1.27.

    ②Group two who got the cake on a paper plate would pay 76 cents.

    ③Group three who got the cake on a piece of paper would pay 53 cents.

    Take some time to make your healthy food look amazing.Cut your fruit into a flower shape and put your colourful vegetables on nice plates.This works really well for your appetite (胃口).

    Out of sight,out of stomach

    Dr.Wansink also found that when people sat at the desk full of snacks,they ate 71% more of snacks a day than those sitting near a clear table.We eat what we see.As a result,put all the unhealthy food in your fridge.

    Hide it and make it really hard to get to.The closer bad food is,the more you eat it.

    Computer technology has become a major part of people's lives. This technology has its own special words. One example is the word " mouse". A computer mouse is not a small animal that lives in buildings and open fields. It is a small device (装置) that you move around on a flat surface in front of a computer.The mouse moves the cursor (光标) on the computer screen.

    Computer expert Douglas Engelbart developed the idea for the mouse in the early nineteen-sixties. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer.

    Using a computer takes some training. People who are experts are sometimes called hackers. A hacker is usually a person who writes software programs in a special computer language. But the word" hacker" is also used to describe a person who tries to steal information from computer systems.

    Another well known computer word is Google. It is the name of a popular search engine for the Internet.People use the search engine to find information about almost any subject on the Internet. The people whostarted the company named it Google because in mathematics, googol, spelled g-o-o-g-o-l,is an extremely

    large number. It is the number one followed by one hundred zeros.

    When you "Google" a subject, you can get a large amount of information about it. Some people like to Google their friends or themselves to see how many times their name appears on the Internet. If you Google someone, you might find that persons name on a blog. A blog is the shortened name for a Web log. A blog is a personal Web page. It may contain stories, comments, pictures and links to other websites. Some people add information to their blogs every day. People who have blogs are called bloggers.
