What do you want to be when you grow up? A teacher? A doctor? How about an ice-Cream taster?

Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream as well as for developing over 75 flavors （味道）.

Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food science degree would be very useful to someone wanting a career in this “cool” field.

In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12 F. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.”

While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,”he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the color expected from that flavor?”Next it’s time to taste!

Continuing to think up new ideas、try out new flavors、and test samples from so many kinds of ice cream each day keeps Harrison busy but happy working at once cool job.

65．what is John Harrison’s job?

A．An official.

B．An ice-cream taster.

C．A chemist.

D．An ice-cream manufacturer.

66．According to John Harrison, to be qualified in the “cool field”, it is helpful to .

A．keep a diary of work

B．have a degree in related subjects

C．have new ideas every day

D．find out new flavors each day

67．What does Harrison do first when testing ice cream?

A．He stirs the ice cream.

B．He examines the color of the ice cream.

C．He tastes the flavor of the ice cream.

D．He lets the ice cream warm up.

68．Which of the following is probably the best title of the passage?

A．Tasting with Eyes

B．Flavors of Ice Cream

C．John Harrison’s Life

D．One Cool Job

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

When you are hungry, what will you respond ? Have your favorite meal and stay quiet after that？ 1 But it never lets you know，because you keep it busy thinking about your friends or favorite stars．So it silently serves your needs and never lets itself grow．When mind loses its freedom to grow，creativity sets a full stop．This might be the reason why we all sometimes think “What happens next？”, or “Why can’t I think？”

2 Why reading but not watching TV？It is because reading has been the most educative tool used by us right from childhood．Since it develops other aspects of our life，we have to take help from reading．

When you read a book，of course you run your eyes through the lines and your mind tries to explain something to you． 3 Now this seed is unknowingly used by you to develop new ideas．If it is used many times，the same seed can give you great help to relate a lot of things，which you would have never thought of in your wildest dreams!

This is nothing but creativity． 4 Within no time you can start talking with your friends in English or any other language and never run out of the right words．

So, friends, do give food to your thoughts by reading, reading and more reading． 5 Go and get a book!

A．The interesting part of the book is stored in your mind as a seed．

B．Why not do some reading while you are hungry?

C．Just like your stomach, your mind is also hungry．

D．Now what are you waiting for?

E．Hunger of the mind can be actually solved through wide reading．

F．Reading can help you make more friends, too．

G．Also this makes a significant contribution to your vocabulary．

Creativity(创造力) is the key to a brighter future, say education and business experts. Here is how schools and parents can encourage this important skill in children.

　 Creativity is not something one is just born with, nor is it necessarily an indicator(标志) of high intelligence(智力). Just because a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using his resources to produce new ideas that are good for something.

　 It is important to let children choose. From an early age, children should be allowed to make decisions and understand their results. Even if it's choosing food for lunch, making decision helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money, but not help them too much if they make the wrong decision. The child may have a hard time, but that is all right. This is because the most important characteristic of creative people is a very strong desire to find a way out of trouble.

1.Creativity is something ______.

A. that people are born with

B. that depends on intelligence

C. that is a way of using what one has learnt to work out new problems

D. that is not important

2. What should the parents do when their children decide how to spend their money?

A. Try to help them as much as possible.

B. Take no notice of whatever they do.

C. Help them if their decision is wrong, but not too much.

D. Leave them as they are.

3.What is the proper title of the passage?

A. The Problems in Education B. Let Children Choose

C. Children Need Creativity D. A Brighter Future

Most Americans enjoy moving from one place to another. They are always in constant motion. For example, they often drive their cars 120 to 160 kilometres away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one house in five has people living in it for more than five years. One may be born in one city, and go to school in another. He may finish his middle school education in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from job to job, which is called “job-hopping”,is a very common practice in the United States.

Job-hopping does good to workers, because every chance to change a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives employers, bosses, managers the chance to benefit from the new ideas and skills that different people bring to their factories.

1.The meaning of the underlined words is close to “_____”.

A. looking for jobs everywhere B. always feeling excited in movement

C. enjoying themselves while moving D. keeping moving from place to place

2.In some places in America,______ in one place for more than five years.

A. most people stay B. about one fifth of the people live

C. the owner of one house stays D. the owners of five houses stay

3.It seems that the writer thinks job-hopping________.

A. is a practice worth trying B. only does good to workers

C. may cause troubles D. make many people lose their jobs

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.

Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.

How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?

This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.

In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.

40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.

A. what stem cells were B. whether they would grow back

C. how long it would take to re-grow D. how they would re-grow

41. A newt will re-grow its leg if _____.

A. its ankle was cut off but the nerve bundle was good

B. its leg was cut off and the nerve bundle stopped growing

C. its leg was cut off and the nerve bundle could grow back

D. its ankle and the nerve bundle were cut off

42. What do the underlined words “these materials” refer to?

A. Nerve bundles and proteins. B. Proteins similar to n-AG.

C. Stem cells and proteins. D. Stem cells and nerve bundles.

43. The first sentence of the passage _____.

A. acts as a lead–in B. shows where researchers got their new ideas

C. states the author’s opinion D. describes the result of researchers’ studies
