It’s not polite to arrive at a dinner party more than 15 to 20 minutes late. The host or hostess usually waits for all the guests to arrive before serving the meal. If someone is late, the food may be spooked , and so might the host of hostess’s spirit. If you will have to be late, call and tell them to start without you.

  It’s even worse to be early !the host or hostess will probably not be ready. If you are early, drive or walk around the block a few minutes, or just sit in your car until the right time.

  Though it’s often important to arrive at a party on time, yet on the other hand, for open houses, he host or hostess invites guests to arrive and leave between certain times, so you can arrive at any time within the times he or she gives you.

  It’s nice to bring an empty stomach, but it’s even nicer to bring a small present. The present should not cost a lot, or you might embarrass the host or hostess. Flowers, wine, or a box of candy will do fine. Never bring more as a present.

In an introduction, the order of a name is (1)the given name, (2)the family name. In other words, the given name comes first. It’s important not only to learn and remember names, but to repeat them often in conversation. After the introduction, we usually call friends by their given names. Older people may want you to call them by their titles and family names, such as “Mr.Jones”, “Mr.Smith”,”Ms.Johson”,or “Dr.Brown”.

  A maiden name is a woman’s family name at birth. In the United States and Canada, after a woman marries, she takes the family name of her husband in place of her maiden name. It is now becoming common, however, for women to keep their maiden names after they get married.

How much rain has fallen on the earth in the past? Man has not always kept weather records. Because scientists need a way to learn about past rainfall, they study the tree rings.

A tree’s trunk (树干) keeps growing year by year. Under its bark (树皮), a tree adds a layer of new wood each year it lives. If you look at a tree stump, you can see the layers. They are called annual ring (年轮).

On some trees, all of the rings are of the same width. But the ponderosa(美国黄松) that grows in the American southwest have rings in different withes. The soil in he southwest is dry. The pines depend on rainfall for water. In a year of good rainfall, they form wide rings. In a dry year, they form narrow ones.

Scientists do not have to cut down a pine to study its rings. With a special tool, they remove a narrow piece of wood from the trunk without harming the tree. Then they look at the width of each ring to see how much rain fell in the year it formed.

Some pines are hundreds of years old and have hundreds of rings. These rings are from an annual record o0f past rainfall in the southwest.
