A food additive (添加剂) 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(使稳定), thicken, harden, 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 will go through strict testing before they can be placed on the market. For most people, the chances of developing serious side effects (副作用) from the long-term use of presently approved (批准) food additives are very small.
1.From the passage we can learn that .
A. natural foods are much safer than man-made ones
B. it is right to refuse chemicals in food

D. all foods have chemical substances

A lazy Susan is an addition to a table that is designed to assist in moving food from one person to another while dining. This is achieved through the use of a turntable (转盘), which usually moves the food in a circle when it is pushed by those at the table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place on the lazy Susan.
A lazy Susan may also be a part of a kitchen cabinet (橱柜). In this sense, the lazy Susan is a type of shelving unit within the cabinet that is able to turn around its axis(轴心) . One may turn the lazy Susan in order to find certain goods in storage. From the outside, a lazy Susan appears to be two cabinets that are located at a right angle (直角) to each another. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
It is believed that Thomas Jefferson invented the lazy Susan in the 18th century, though it was called “dumbwaiter” at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph (留声机). The turntable may have developed into the lazy Susan later.
Regardless of who invented it, it wasn’t until 1917 that the term “lazy Susan” was used in an advertisement for the invention. In Britain, however, the term “dumbwaiter” is still used rather than “lazy Susan”. The reason for the naming of it is still a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
1.What is a “lazy Susan”?
A. A waitress B. A convenient tool C. A table D. A cabinet
2.According to those who believed Thomas Jefferson invented the lazy Susan, _______.
A. his daughter was very lazy B. the lazy Susan didn’t exist until the 18th century
C. Thomas Edison was his friend D. Thomas Edison didn’t invent the phonograph
3.We can learn from the last paragraph that ___________.
A. the lazy Susan can work by itself
B. the lazy Susan was named after Thomas Edison’s daughter
C. how the lazy Susan got its name remains unknown
D. the lazy Susan was invented in Britain
4. The writer wrote the passage mainly to _________.
A. discuss how the lazy Susan was named B. teach us how to make a lazy Susan
C. introduce Thomas Edison’s inventions D. tell us what a lazy Susan is and its origin

Puppy Food
A puppy (young dog) is a precious addition to any family. The excitement of bringing home a little furry friend will always live in our memories. Like all of us, though, your puppy must have adequate nutrition right from the start to make certain that it'll have a long and healthy life.
1. You might ask yourself what is the best for your new pet with all of the different varieties on the market in all of their attractive packaging. Some dry food produced specially for puppies is the best for the development of their teeth. 2.
Contrary to the belief of many first-time puppy owners, it is not always the best idea to purchase food that is too high in calcium(钙), protein, and vitamin levels.3. In addition, a high intake of calcium is associated with bone disease in large-breed dogs. If you have a "small-breed" puppy, you can buy that kind of food.
It is not a good idea to feed the food you eat to your puppy frequently, as your puppy may become selective about food.4. Some people think that dog biscuits and other treats are fine, but they should not be a main part of puppy's diet.
Young puppies should be fed three times a day. Each puppy is unique, however, so feeding them twice a day is acceptable. After ten to twelve weeks of age, feed your puppy twice per day. Allow your puppy to eat as much as he would like in fifteen minutes.5. If you let your puppy eat too much or too often by keeping food accessible at all times, he may become overweight and have health problems as an adult. Like humans, your puppy will not enjoy the food any longer if it is there at all times.
A. Pick up the dish with the remaining food.
B. Proper food is a basic necessity for your puppies.
C. Remember to give your puppy the food he would like to have.
D. It can also cause an upset stomach due to an unbalanced diet.
E. A further benefit is that it is less expensive than the canned food.
F. One example is that extra helpings of nutrients do harm to digestive organs.
G. It's good to provide the extra nutrients a puppy needs until he grows larger.

All right! Enough cookies,cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes.The kids see well-known personalities eating potato chips, candy and other processed food, and they want to be like their heroes.How do they do it?They eat the same food. I wish there were more characters like old Popeye(大力水手), the sailor, who ate spinach(菠菜) and not French fries.
Now I don't expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I'm glad to cook traditional meals of meat and potatoes for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives(防腐剂), and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don't want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don't get my essential(必要的) proteins. I feel better than ever and I'm sure that it's because I'm a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
1.According to the passage, it seems that ______.
A.canned food is the only one that the kids enjoy most.

“Farm to table” is the name of a movement that encourages people to eat locally grown food. The farm-to-table idea has become more popular in recent years. But there is also a movement that brings “table to farm”. Its purpose is to connect people to the land and to honor local farmers by creating a sort of restaurant without walls.
Its founder, Jim Denevan, got the idea for this kind of “culinary adventure (美食探险)”, as he called it, ten years ago. He recently prepared tables for more than a hundred people at Briars Farm in Virginia. He and his eight-member team arrived the night before. Chefs (厨师) from a local restaurant prepared the dinner.
Jim Denevan’s brother is a farmer and he himself is a chef. He thought that the idea of a meal served right on the farm made sense, though not everyone agreed.
“But I wanted to make the idea work, so I decided to cross the country, “ said Denevan. “I went all the way across the United States and set the table on farms, ranches (大牧场) and beaches, and all the places where food came from. “
“This kind of event connects us with a lot of enthusiastic people, people that we can form relationships with, “ said Matt Szechenyi, who operates Briars Farm.
The tour of the farm ends at the dinner table. The meats in the meal come from Matt Szechenyi’s farm. The vegetables come from nearby farms. Guests and local farmers sit together.
Annoica Ingram came with a friend. “The food is wonderful. I appreciate their hard work. I see everything they have to do to take care of the animals and make sure they are well-cared-for. Without them, I think, we’ll have big problems, “ she said.
1.What is the main purpose of the movement “table to farm”?
A.To provide people with healthy food.
B.To help farmers earn more money.
C.To honor farmers for their hard work.
D.To encourage people to work less and practice more.
2.Annoica’s attitude towards farmers’ work is ______.
A.worried
B.grateful
C.doubtful
D.supportive
3.What kind of writing is the passage likely to be?
A.A travel guide.
B.A news report.
C.A diary.
D.Popular science.

How To Help Teens with Time Management
Time management is a skill that any teen will need to learn to help him succeed. No matter how intelligent or skilled your teen is, he needs to be able to effectively manage his time to help him make the most of his potential. He will need to have the discipline to learn to prioritize(优先处理) effectively. 1.
Help your teen learn to prioritize. Not everything is of equal importance, though it may seem that way to your teen. 2. Family time is also important, more so than time spent with friends on tweeting online. School work should come first, over watching TV or surfing online. Enforce (实 施)the rule in your home, so your teen knows that he can't turn on the electronics until his work is clone.
3. Don't overload your teen with activities. Extra-curricular(课外的)activities are fun and help make your teen a better rounded individual. After school work and volunteer programs look great on a college application form. However, if it cuts in on your teen's schoolwork or he seems stressed or overworked, you may need to step in and help him cut back.
Have a system. 4. For example, provide a quiet and private workstation for your teen. Teach your teen to make sure that it is organized, so he doesn't waste his time looking for things, which is a big time waster.
Give him a planner. Place a calendar in your teen's room or in the family room, so your teen can write in his activities. 5. If having a planner or Filofax (备忘记事本)is to old school for your teen, a blackberry or other digital organizer can help him get organized.
A. Limit activities.
B. Set an example.
C. Help your teen be organized.
D. As a parent, here's what you can do.
E. This will help your teen make sure he doesn't forget anything.
F. Children learn by what they live, so you have to practice what you advocate.
G. Remind your teen that his priority is to learn al school and complete his schoolwork.
高一英语七选五中等难度题查看答案及解析
It is quite natural for all of us to want to preserve and protect the foods we purchase. With that in mind, we often think that the best way to do that is by putting them in our refrigerators. However, that is not always the case.
Bread
Nothing dries out bread faster than your refrigerator. In the event that you have made sandwiches with the bread, then you can place them in the fridge. The cold temperature will make the bread tough and chewy.
Tomato
We all love tomatoes for their taste. But putting them in the refrigerator will cause them to lose all of their flavor (口味). Plus, the cold air in the cooler stops the ripening process as well. And as we all know, ripening is what gives every tomato more taste and flavor. For best results, keep tomatoes out, and inside a basket or a bowl on your counter.
Salad
Oil or vinegar based salad can be stored for a long period of time without refrigeration. Moreover, refrigeration of salad dressings brings bad smell. Keep in mind that some salads that are mayo (蛋黄酱) or yogurt based should be refrigerated in order to keep them fine. So if you have some salads that have been already dressed, you can keep them away from your fridge without any hesitation.
Egg
It is a long debate whether you should keep eggs inside your refrigerator or not. One study suggests that keeping eggs whether in a refrigerator or not does not change their normal qualities, so it can be said that if you keep eggs at room temperature, there should not be any problem. There is another study that shows that keeping eggs inside the refrigerators has a bad effect on the natural taste and flavor of eggs, so it is wise to keep eggs outside of your fridge.
1.Which of the following lose(s) water quickest in the cooler?
A.Bread B.Tomatoes.
C.Salad. D.Eggs.
2.What should we do with tomatoes to get the best taste?
A.Put them in the cooler. B.Cook them at once.
C.Make them ripen faster. D.Leave them in the shade.
3.What will go bad easily without refrigeration?
A.Dressed salad. B.Mayo and yogurt.
C.Oil and vinegar. D.Salad dressings.
