American parents usually think that their child should not have more pocket money than the children with whom he regularly connects no matter they are wealthier or not than he.
Whatever the pocket money is, its entire use is not controlled by the parents, because a child learns to use money correctly only through dealing with it himself. If a seven-year-old child gets a quarter as a week pocket money and is made to put it all in his piggy bank to save it up, he gets no idea what the real use for the money is. He gets the shiny coins and they soon disappear. The idea of a bank account(在銀行開戶) is too early for so small a child, although he can be made understand and enjoy saving his coins-not all of them, only a part of what he receives-to buy something he especially wants. By the time he is eight, he is old enough to take part in the opening of his own savings account, parents may take him to the bank, open a saving account for him, and encourage him to put a certain quantity(數(shù)量) of money he receives as gifts into the bank and watch his bank saving grow as entry by entry(存入)is made. He will be saving, earning, and spending suitable quantities all along in order to learn how to manage money and to keep him in a favorable position with his friends. The boy is a sorry child who can't join his fellows in a sweet shop once in a while because he has to save every cent he gets or earns for some big unknown projects his parents have chosen for him.
63. What does the underlined word "piggy bank" refer to?
A. Something in the shape of a pig for saving coins.
B. A kind of bank run by the children.
C. A bank whose building looks like a pig.
D. A bank for children's saving.
64. Which of the following statement is NOT true?
A. Whatever the pocket money is, its entire use is not controlled by American parents.
B. If an eight-year-old child receive 10 dollars as his birthday gift, he probably have most of it saved in the bank.
C. American parents never interfere(干涉) with their children's use of their pocket money.
D. American parents don't usually give their children much pocket money.
65. Why does the author think the boy is a sorry one if he saves every cent he gets or earns?
A. Because he can not manage his money and it keeps him in an unfavorable position.
B. Because he can not learn the use of money through spending it himself.
C. Because he can not have any other choice but to save, earn or spend money.
D. Because he can not join the fellow in a sweet shop once in while.

People in cities all over the world shop in supermarkets. When you enter the supermarket, you see shelves full of food. You walk in the aisles, pushing your shopping cart. You probably hear soft, slow music in the supermarket. This kind of music is playing to relax you and make you walk slowly. Thus, you will probably stay longer and buy more food.
Where do you go in the supermarket when you first arrive? Many people go to the meat section first. This area of the store has many different kinds of meat. Some kinds are expensive and others are not. Usually, some kinds of meat are on sale. So it has a special low price. The manager of the store knows where the customers usually enter the meat section. The meat on sale is usually at the other end of the section, away from where the customers enter. If you want to buy this specially priced meat, you have to walk by the more expensive meat first. Maybe you will see something that you want to buy before you reach the cheaper, inexpensive meat. Then you will spend more money in the meat section.
The diary section sells milk that is low in fat. Some supermarkets sell three different containers(包裝盒)of low-fat milk. Each container looks different, but each contains the same product. One says "1% fat", one says "99% fat free" and one says "low-fat" in big letters and "1%"in very small letters. If you look carefully you can see that all the milk has the same amount of fat, and each container is the same size. The prices of all these three should be the same. However, in many stores these three containers of milk would each have a different price. The store will make more money if a customer chooses the milk that costs the most.
Most of the food in supermarkets is very attractive. People often stop to look at the products in attractive containers. But remember, many products will say, "Buy me!". Stop and think which ones are the best value for your money.
59. The word "aisles" in the first paragraph means _______ .

Pottery is the name given to all kinds of useful or artistic objects made from clay. Pottery can be plates or water pots or baskets. Pottery can be large or small, fancy or plain. Pottery is part of the large family of ceramics(陶器).Ceramics are synthetic materials. For example, bricks and tiles (瓦片) are both ceramics.
How is pottery made? First, a potter takes some clay. Clay is a soft, red material from the earth. It looks a little like red dirt, but it's very different. Clay is thick and rich. Wet clay can be worked into any shape. When the clay dries, it will keep that shape. The potters takes some clay and pushes and squeezes(擠壓)it until it is soft and smooth. After that, the clay can be shaped into anything. There are several ways to shape clay. Sometimes potters use their hands. Sometimes they use a special wheel. They place the clay in the center of a round, flat wheel. The wheel moves very fast, and the potter shapes the clay.
After the potter has shaped the clay, it can be decorated(裝飾). Potters use glaze, which is a kind of paint, to decorate their work. Some glazes are very simple. Other glazes have beautiful colors and designs. The glaze is not just beautiful. It is also useful. The glaze makes the pottery smooth and waterproof. Potters also make some decorative lines and designs on the surface. After it is decorated, the clay must be baked, or fired, in a special oven.
Baking the clay at very high temperature makes it hard and strong. Firing also makes the glaze stick to the pottery. When the firing is over, the potter carefully removes the pottery from the oven and lets it cool slowly. If it cools too quickly, it could crack and break.
Since pottery is waterproof, it is very popular for dishes. You can find examples of pottery in almost any home. But pottery can also be found in museums. Some pieces of pottery are valuable and beautiful pieces of art.
56. It is possible that ceramics are materials of _______ .
A. metal B. plastic C. wood D. earth
57. The word "waterproof" means _______ .
A. 能盛水的 B. 防水的 C. 溶解于水的 D.吸水性強(qiáng)的
58. Which statement is NOT true according to the passage?
A. Plates, water pots and bowls are all examples of pottery.
B. Wet clay can be made into anything of different shapes by the hands or a special wheel.
C. The clay becomes smooth and waterproof because of the glaze.
D. After the firing in high temperature, pottery is easy to break.
