The Fish Tomato and other GM Foods

1. Did you know that scientists have put a fish (1) _______ into a tomato? They did it to develop tomatoes which can grow in cold temperatures.

2. So what are genes? Genes are instructions which exist inside every cell of every living thing. Each cell in the human body contains about 25,000 to 35,000 genes which determine your eye colour, how tall you are, what skills you have, and so on. So if you (2) _______ a plant gene, you can change a specific characteristic like colour, shape or height.

3. (3) _______ changes the genes of plants or animals to make genetically modified organisms (GMOs). Scientists believe that GMOs can help us in many ways. For example, GM (4) _______ can produce more food which contains more (5) _______. They can also have an engineered resistance to insects and (6) _______, and stay fresh for longer. GMOs can make fish grow larger and make cows produce healthier milk. Some people think that if we want to feed the world’s population, we will need GMOs.

4. But does genetic engineering work? Farmers use (7) _______ to kill weeds, but these chemicals can also damage crops. In the USA, farmers use GM crops which resist herbicides, so that they can destroy (8) _______ without damaging the crop. However, some ‘superweeds’ are becoming immune to the herbicides, so the farmers have to use more and more chemicals.

5. Food is very important to all of us and many people believe we are what we eat. These people are worried about the overuse of chemicals and the possible effects of eating GMOs. Some governments oppose them. What do you think?

In the UK we each use about two hundred steel food and drink cans every year. Steel cans are popular because they are convenient, easy to store and unbreakable. But when you have finished with a can what do you do with it? Do you throw it away and forget all about it? Probably! But behind the scenes there are people whose work is to make sure that the steel is never wasted. In fact, recycling or re-using steel cans is so successful that every day of the year more than five million cans start new lives in new steel products.

After you have thrown away your can, what happens? Well, first of all it is collected by the men who empty your dustbin each week and take to a tip, together with all the other household rubbish. Then the rubbish is sorted and the steel cans are taken separately to a special factory which turns old cans into high quality steel. It’s this steel that may well find its way back into your home in the form of knives and folks, garden equipment and, of course, food and drink cans.

So next time you open your fizzy drink, just remember where your can may have been!

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants. If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas. In fact, we would not even know for sure that there were once seas in some regions...

Unlike buried treasure and some minerals, fossils are usually not valuable in themselves. However, most of the fossils you find will be of greatest value to you. They will help you learn much about the geologic history of the earth and its inhabitants.

If it were not for fossils, we would have no way of knowing about the animals that once roamed the earth or that once crawled on the bottom of the ancient seas. In fact, we would not even know for sure that there were once seas in some regions if it were not for the many fossils of sea animals that we find there.

You can look at some fossils and see for yourself the shape of the ancient animals. Even if you collect only bits of one kind of fossil, you may still be able to tell what it looked like. Making sense out of fossil bits is a little like working a jigsaw puzzle. Sometimes you will lose pieces, but you can still recognize the picture and even use your imagination to fill in missing details. The habits of ancient sea animals are not so easy to determine. Therefore, scientists study the structure and the habits of similar living animals to learn what the ancient ones must have been like. There are some things, however, that neither the study of fossils nor the study of living animals can tell us. For example, no one knows what colour most ancient sea animals were. Also, since the soft parts disappeared soon after death, many details of their internal structure are unknown. So the pictures of ancient sea creatures (as well as dinosaurs!) are what scientists think the animals looked like. Reconstructing the life of an ancient sea animal on the basis of fossil evidence and the characteristics of similar living animals is a little like relying on circumstantial evidence in court.

1. This passage is mainly about animals that __________.

A. have very tough hides

B. once lived on the earth

C. inhabit the seas of today

D. are becoming extinct

2. With the help of fossils we can __________.

A. reconstruct life of the past

B. predict the future

C. explain the changes of the seasons

D. save some species of animals from extinction

3. Many details of ancient animals are lacking because __________.

A. many species have not been found

B. volcanic disasters have permanently buried many fossils

C.many fossils lie in deep water and cannot be recovered

D. soon after death the soft parts of the body decay

49. To “determine" in the passage is closest in meaning to __________.

A. come across

B. study

C. find out

D. imitate

50. This passage implies that a scientist's evaluation of the past is based on __________.

A. laboratory experiments with live animals

B. a few facts mixed with a lot of opinions

C. predictions made in the past and present

D. field studies of our society
