Read the following paragraph carefully and select the best topic sentence from the fou
r possible answers that follow the paragraph.

Vending machines sell many different types of items.Some of them sell cold drinks like soda, or hot drinks like coffee or hot chocolate.Others sell candy, stamps, tickets, newspapers, and other types of small merchandise.These machines have been successful for two reasons.They save time and they are convenient.Merchandise sold in machine eliminates the need for a sale clerk or cashier.In many places the customer puts a coin into the machine and then pushes a button, pulls a lever, or opens a door to receive the merchandise.Some machines will also return change to the customer, and a few will make change for paper money.But the basic idea is the same.Customers like to save time and are usually willing to pay a higher price for this convenience.The sale of snacks in vending machines has always been very successful.However, machines now sell hot meals with only limited success.In New York city, automates used to sell a lot of hot foods in vending machines.But in recent years, fast food establishments have replaced automates.()

During the early American colonial years, com was more plentiful than wheat, so com breed
was more common than wheat bread. Friendly Indians showed colonists how to grow com and how to prepare it for food and pioneer women then improved the Indian cooking techniques. When people traveled, they went on foot or horseback, sleeping and eating in the forests. They carded com bread for sustenance; the com bread came to be called journey cake. Later when roads and taverns were built and stagecoaches carded passengers, journeycake became johnnycake, a name many easterners still use for corn breed. The kinds of bread made with cornmeal were-and still are-almost without limit. Every region has its specialties.

In colonial times, why was com bread more common than wheat bread?

A.The colonists preferred com breed.

B.Corn was more abundant.

C.The colonists did not know how to make wheat bread.

D.Com bread did not spoil as rapidly as wheat breed did.

How do young children learn to have good values? How can parents teach their children
How do young children learn to have good values? How can parents teach their children about the importance of kindness, patience, and self-discipline? At a time when more and more parents worry about the negative and violent images(暴力形象) their children see on TV, in the movies and, on the Internet, some are turning to fairy tales(童话) as a way to teach their young ones how to behave in society.

Fairy tales were not always intended for children.We know this because some of these stories have existed for hundreds of years and were passed down from generation to generation through songs and drama.They were considered entertainment for everyone, not only for young people.In these ancient stories, the heroes were extremely clever, fiercely independent, and never gave up.Over the years, some of the heroes’ qualities and story lines have been changed to fit the times. Psychologists think that fairy tales have a positive influence on children because they present the two sides of good and evil very clearly.When children hear the stories, they develop sympathetic feelings for the heroic characters.In each tale, they can see that there are many different kinds of people in the world and that we all have a choice about what kind of person we want to be.We can choose to do good actions, rather that bad ones, in our lives.

What kind of values can children learn from fairy tales? In “The Princess and the Pea,” a poorly dressed girl who insists she is a princess is given a difficult test by the Queen.When she passes the test, we learn that she is rewarded because she stayed true to herself.In “The Little Mermaid,” the mermaid(美人鱼)who lives under the sea longs to be with the humans on land.Through her experiences, we learn about the importance of living with and accepting other cultures.In “Pinocchio,” a wooden puppet(木偶)turns into a boy when he finally learns how to tell the truth. Teaching values is the reason most often given for teaching literature and encouraging reading.These old stories can indeed teach us lessons about human relationships that are universal(普遍的) enough to survive throughout the centuries.This might be the reason why they have been around for so long and are unlikely to disappear any time soon.

1.What do we learn about fairy tales from the passage? _______

A.to reflect the change of values

B.to suit the tastes of different people

C.to arouse the interest of little children

D.to adapt to the change of the times

A.learn to be better self-disciplined

B.be more likely to tell the truth than to tell lies

C.learn to stay true to themselves all their lives
