"Opinion" is a word that is used carelessly today. It is used to refer to matters of taste, belief, and judgment. This casual use would probably cause little confusion if people didn’t attach too much importance to opinion. Unfortunately, most to attach great importance to it. "I have as much right to my opinion as you to yours, '' and ''Everyone’s entitled to his opinion, '' are common expressions. In fact, anyone who would challenge another's opinion is likely to be branded intolerant.
 Is that label accurate? Is it intolerant to challenge another's opinion? It depends on what definition of opinion you have in mind. For example, you may ask a friend ''What do you think of the new Ford cars?" And he may reply, "In my opinion, they're ugly." In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, ''It's pointless to argue about matters of taste."
 But consider this very different use of the term, A newspaper reports that the Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not shale their personal preferences, their mere likes and dislikes, They stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation.
 Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence.
 Is everyone entitled to his opinion? Of course, this is not only permitted, but guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others.

When I told my family that I was thinking of taking a cooking job, the roars of laughter were rather discouraging. No one believed that I could cook at all, as I had never had a chance to practise at home. Our cook had ruled in the kitchen for thirty years and had an annoying tendency to regard the pans, stove and all the kitchen fittings as her own property.

I once crept down there when I thought she was asleep in her room to try out an omelette(炒蛋). Noiselessly I removed a frying pan from its hook and the eggs from their cupboard. It was the pop of the gas that woke her, I think, for I was just breaking the first egg when a pair of slippered feet moved round the door and a shriek(尖叫声) of horror caused me break the egg on the floor. This disaster upset her so much that she locked herself in the storeroom with all the food and we had to make our Sunday dinner of bananas.

If the family weren’t going to be helpful, I would look for a job all by myself and not tell them about it till I’d got one. I had seen an agency in a local paper, so as soon as there was no one about to say “Where are you going?” I rushed out of the house in search of it.

I sat on the edge of a chair and could see my nose shining out of the corner of my eye. I thought perhaps it was a good thing; it might look more earnest. The woman at the desk examined me through her glasses. Having asked me a few questions, she told me that it would be difficult to get a job without experience. “But”, she said, “I’ve got someone who needs a cook badly.” She wrote down a number, and my spirits went up as I took the slip of paper she held out to me, saying: “Ring up this lady. She wants a cook. You would have to start tomorrow by cooking dinner for ten people. Could you manage that?”

“Oh yes,” said I—never having cooked for more than four in my life.

All food chains begin with the sun, and all food chains become broken up if one of the links disappears.
All life depends on energy from sunlight. Only plants can use this energy directly. Their leaves are little factories that use sunlight to make food from water and things in the soil and air. Plants in turn serve as food for all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.
What about human beings? We are members of many food chains. We eat vegetable and fruit. We also eat meat and drink milk. This means the sun’s energy passes through plant to animal before it reaches us.
Nature is a great thing. Any food chain always produces enough for each of its members if it is left alone. When there isn’t enough food for any link in the chain, some of its members die off. So the balance is always kept.

1.If one of it’s members dies off, any food chain will________.

A. come off B. become better

C. fall apart D. come into being
