听力原文： Health food is a general term applied to all kinds of food that are considered more healthful than the types of foods widely sold in supermarkets. For instance, whole grains, fried beaus, and corn oil are health foods. A narrower classification of health food is natural food, which is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas relined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health food is organic food, which is used to describe food that has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens that are only treated with organic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meats, fish, dairy and poultry products from animals that are fed only organically-grown feed and that are not injected with hormones are organic foods.
In choosing the type of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the claims that processed foods contain chemicals, some of which ate proven to be poisonous, and that vitamin content is greatly reduced in processed foods.
(30)
A．Refined food.
B．Processed food.
C．Natural food.
D．Organic food.

From there, the bags make their way in refrigerated trucks to thousands of McDonald's restaurants up and down the Eastern Seaboard. No more than 14 days after leaving the plant, the fruit will take the place of French fries in some child's Happy Meal. The apple slices, called Apple Dippers, are a symbol of how McDonald's is trying to offer healthier food to its customers？ And to answer the many critics who contend that most of its menu is of poor nutritional quality.
It remains to be seen whether these new offerings will assuage the concerns of public health officials and other critics of McDonald's highly processed fat and calorie—laden sandwiches, drinks and fries. So far, they have notat least not entirely. But this much is already clear: Just as its staple burgerandfries meals have made McDonald's the largest single buyer of beef and potatoes in the country, its new focus on fresh fruits and vegetables is making the company a major player in the $80 billion American produce industry.
The potential impact goes beyond dollars and cents. Some people believe that McDonald's could influence not only the volume, variety and prices of fruit and produce in the nation but also how they are grown.
According to the text, what will be found in some children's Happy Meal instead of French fries？
A．Apple pies.
B．Hamburger.
C．Apple dippers.
D．Apple flavor French.

The majority of people in this country eat too much fat and not enough fibre (纤维) and for most people having a healthy diet is simple and easy to do. The move towards a healthy diet may just mean eating more fruit, vegetables, bread and potatoes.
There are 5 basic food groups and a healthy diet consists of eating a variety of foods from each of the groups.
1. Bread, potatoes, rice, noodles,and breakfast cereals.
These foods mostly contain starch (淀粉) and should be the main part of all your meals. If possible try to choose high fibre varieties. This group of foods is an excellent source (来源) fibre and is rich in vitamin (维生素)
2. Fruit and vegetables
This includes all frozen, fresh and canned fruit/vegetables as well as salad vegetables. These are all excellent sources of vitamins minerals and fibre and are naturally low in fat and calories.
3. Milk and dairy foods
Milk and dairy products include cheese, yoghurt and milk. They are rich in protein (蛋白质) calcium, vitamin and minerals.
4. Meat, fish and poultry (家禽)
Eating fish 1-2 times a week is good for you. All types of meats are included in the category and red meat is excellent source of iron and vitamin B12. Nuts, peas and beans are also in this food group.
5. Foods containing fats and sugars.
This last group contains butter, cream, ice cream, cooking oil, cakes, biscuits, chocolate, sugary drinks, sweets and crisps. All of these foods tend to be high in fat and calories.Try not to eat these foods too often and when you do, only have them in small amounts.
(1)、What’s the problem with many people？
A、Not enough sleep
B、Staying up late
C、Eating too much fat and not enough fibre
D、Under stress
(2)、What does a healthy diet mean？ It means （）.
A、five different kinds of foods a meal
B、different kinds of foods from the 5 basic food groups
C、different kinds of fruits and vegetables
D、less fruit, vegetables, bread and potatoes
(3)、We should try not to eat foods from （） too often.
A、Group 5
B、Group 4
C、Group 1

The Advantages and Disadvantages of Buying Lottery
Tomato Ripening
Tomatoes give off minute quantities of ethylene gas which is active in starting the natural ripening process. If left to nature, however, the tomatoes ripen in a random way. The trickled ethylene gas process of tomato ripening consists of exposing the tomatoes to a low concentration of ethylene gas under controlled temperature conditions in a special tomato-ripening room. This treatment initiates and controls the speed of the natural ripening and colouring process in the tomatoes.
Controlled ripening and colouring enables the grower to market tomatoes of more uniform. colour and quality than is possible with green or fieldripened produce. Timing of harvesting and marketing may, within limits, also be regulated by the use of controlled ripening and colouring in order to achieve maximum returns and make the best use of labour and equipment.
Ripening Conditions
All fruit must be mature green at harvest for controlled ripening to be successfully carried out. Relative humidity does not appear to be of great importance in the tomato-ripening process. Little moisture loss from the tomatoes occurs during the ripening process due to the relatively impermeable nature of the tomato skin. Ripening time will depend on the ripening temperature range, however, ripening temperature above 24℃will result in poor colour development with yellow or orange fruit rather than red. The heating and cooling capacity should be such that the tomatoes can be brought to the recommended ripening temperature within 24 hours.
Room Size and Construction
For efficiency and convenience in operation, on-farm, tomato ripening rooms are usually sized to accommodate the normal daily tomato pick during the peak harvest time. The room capacity is generally in the range of two to ten tonnes of tomatoes. However, larger rooms may sometimes he installed. Since the average ripening time is three or four days, tile provision of multiple rooms on the farm is generally desirable.
Air Circulation and Ventilation System
Fan-forced air circulation is required tbr adequate and uniform. temperature control and ethylene gas distribution in the ripening room. An air circulation rate of two room air volumes per minute is recommended for good results. This is equivalent to around 480 cubic metres of air per hour per tonnes of tomatoes. At the recommended heating or cooling capacity of 0. 6 to 1.2kw per tonne of tomatoes, this gives an air circulation rates are necessary to limit variations in temperature in different parts of the room to acceptable levels and to achieve an adequate rate of heating or cooling of the tomatoes.
The ventilation system circulates the room air continuously, introducing a small proportion of fresh air and exhausting a similar amount of air at the same time. This prevents a build up of ethylene gas in the room and also removes carbon dioxide produced by the fruit during respiration. If this car- bon dioxide were allowed to build up to too high a level in the room atmosphere, it would interfere with the ripening process.
Temperature Control System
The temperature of tomatoes in the ripening room has a great influence on the ripening process. In fact, the product heat load usually represents around 80% of the total heat load. The remainder is due to heat transmission through the exterual walls of the room anti the fresh air exchange rate. In some cases, both heating anti cooling are required to maintain the room temperature within the required range. The time required for ripening can be reduced to some extent by increasing the temperature. Reverse cycle air-conditioners are successfully used for both heating and cooling in tomato-ripening rooms where humidity control does not
