A food additive is any substance that is added to food. Many people are put off by the idea of "chemicals in food". The truth is that all food is made up of chemicals. Natural substances like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas . Some chemical substances are indeed harmful, but a person who refused to consume any chemicals would find nothing to eat. The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory----made substances increase the nutritional value of food.Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange.Like "chemical", "man-made" doesn't necessarily mean "not fit to eat". Food additives are used for many reasons. We add sugar and salt and other things to foods we prepare at home to make them taste better. Food producers have developed a range of additives that stabilize, thicken, harden, keep dry, keep wet, keep firm, or improve the appearance of their products. Additives can make food more convenient or nutritious, give it a longer shelf life, and make it more attractive to the consumer, thus increasing the sales and profits of the producers. Food additives are presently the centre of a storm of serious argument. Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market. Many people feel there's a risk of eating food to which anything has been added. But food additives are now regulated by the FDA of the federal government, and new additives are subjected to strict testing before they can be placed on the market. For most people, the chances of developing serious side effects from the long-term use of... Which of the following is TRUE according to the passage? A) Foods with more additives have higher nutritional value. B) To ensure food safety, the FDA will ban food additives. C) Foods free of additives can keep a much longer shelf life. D) Food additives can improve the quality of foods in many ways.

Car Talk When I got the driving license last summer, Mom and I took our first trip around an empty parking lot. Then I found that my mother was not the best teacher for me. It wasn't that she shouted, or told me that I was doing poorly. As you can imagine, my mother's "helpful instructions" only managed to make me more nervous. Since I could no longer practice with her, the job was placed in the hands of my father. The idea of learning from Dad was not one that thrilled me. I loved him dearly, but I just did not see Dad as someone I could be comfortable learning from. He almost never talked. We shared a typical father-daughter relationship. He'd ask how school was, and I'd say it was fine. Unfortunately, that was the most of our conversations. Spending hours alone with someone who might as well have been a stranger really scared me. As we got into the car that first time, I was not surprised at what happened. Dad and I drove around, saying almost nothing, aside from a few instructions on how to turn. As my lessons went on, however, things began to change. Dad would turn the radio up so I could fully appreciate his favorite Stones music. And he actually began talking. I was soon hearing about past failed dates, "basic body" gym class, and other tales from his past, including some of his first meeting with Mom. Dad' s sudden chattiness was shocking until I thought about why he was telling me so much in the car. In all the years that I had wondered why my father never spoke that much, I had never stopped to consider that it was because I had never bothered to listen. Homework, friends, and even TV had all called me away from him, and, consequently, I never thought my quiet father had anything to say. Since I began driving with him, my driving skill has greatly increased. More important, though, is that my knowledge of who my father is has also increased. Just living with him wasn't enough--it took driving with him for me to get to know someone who was a mystery. With her story "Car Talk", the author indicates that _ . A) fathers love their daughters dearly B) mothers are less patient than fathers C) family members need real communication D) it takes time to improve the father-daughter relationship

(Q).
Shundagarh is a village on India's east-facing coast.It is a village of simple mud and grass houses built on the beach just above the waterline.The Khadra Hills rise immediately behind the village,to a height of one hundred and fifty meters.A simple,good-hearted old man,whose name was Jalpur,farmed two small fields on the very edge of these hills.From his fields he could see the fishing boats that travelled up and down the coast.He could see the children playing on the sands;their mothers washing clothes on the flat stones where the Shiva River flowed into the sea;and their fathers landing the latest catch or repairing nets and telling stories that had no end. All Jalpur owned in the world were the clothes he wore day in and day out,the miserable hut that he slept in at night,a few tools and cooking pots--and his fields.The corn that he grew was all that made life possible.If the weather was kind and the harvest was good,Jalpur could live happily enough--not well,but happily.When the sun was fierce,and there was little or no rain,then he came close to the line between life and death. Last year the weather had been so kind,and the harvest promised to be so good,that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast.He had been thinking about doing this for some years.It was his dearest wish to spend his last days with his son and his wife.But he would go only if he could give;he would not go if it meant taking food out of the mouths of his grandchildren.He would rather die hungry than do this. On the day when Jalpur decided that he would harvest his corn,sell it,and move up the coast,he looked out to sea and saw a huge wave,several kilometers out,advancing on the coast and on the village of Shundagarh.Within ten minutes everyone in Shundagarh would be drowned.Jalpur would have shouted,but the people were too far away to hear.He would have run down the hill,but he was too old to run.He was prepared to do anything to save the people of Shundagarh,so he... Which of the following could Jalpur NOT see from his Fields? A) Mothers washing clothes. B) Fathers taking their corn to market. C) Fishing boats traveling on the sea. D) Children playing on the sands.
