Dear Wang Fang,

    Thank you for your letter. You wrote to ask me about American social customs(风俗) in their dinner party. You are asking the right person. I once lived in America for five years. Now I'll tell you something about it.

    It's a good idea to bring a small present when you go to a dinner party. Flowers are always nice, or you may bring a bottle of wine if you know that your friends drink it.

    You should arrive(到达) on time or five minutes late. Don't get there early. If you're going to be more than fifteen minutes late, you should call before.

    Try to be free at the dinner table. If you don't know about choosing(选择) the right fork or knife, just watch the other people, and follow them. If you still have no idea of what to do, ask the person beside you .

    If you like the food, say so. Of course, you'll thank them for the meal and for their kindness. It's also a good idea to send a card to thank them the day after.

    Do you like shopping? Here are some shopping tips for you.

    First, you should write down all the things you want to buy. You should know how much money you need and take enough money with you. People can bring their own shopping bags now so you needn't buy one from the shop.

    Second, it's very important not to buy the things you needn't. There are many nice things in the shopping mall, but what you need is only some of them.

    Third, when you are shopping , you need to go into different shops and compare(对比)things of the same kind. It may take you lots of time to get the best one.

    Fourth, you can go shopping at the weekend or during holidays. On one hand, there are lots of discounts(折扣) on many things. On the other hand, people have enough time to decide which to buy.

A. Emily often feels tired and seems to be lack of energy.

    If you ask people of different countries "Could you tell me the way to the post office?" you will get different answers.

    In Japan, people use landmarks（路标）instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. {#blank#}1{#/blank#} The post office is across from the bus stop. "

    In Kansas, America, there are no towns or buildings within miles. So instead of landmarks, people will tell you directions and distance. For example, people will say, "Go north two miles. {#blank#}2{#/blank#} "

    People in Greece sometimes do not even try to give directions. They will often say, "Follow me." {#blank#}3{#/blank#}

    Sometimes if a person doesn't know the answer to your question, he or she might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." {#blank#}4{#/blank#}They usually give an answer, but often a wrong one. A visitor can often get lost in Yucatan!

    {#blank#}5{#/blank#}You might not understand a person's words, but maybe you can understand his or her body language. He or she will usually point to the right direction. Go on in that direction and you may find the post office!

    With their long tusks (象牙), elephants look strong. However, it is this feature that makes the animal endangered. Many of them are killed for their tusks. People make elephant tusks into crafts (工艺品) and jewelry and sell them to rich people.
    But can these priceless body parts grow back? The answer is no, Live Science said. The elephants' tusks are actually part of their teeth. Nearly all African elephants and most male Asian elephants have these long teeth. About one-third of the tusk is in the animal's skull (头骨). The tusk has a nerve (神经) running down its center. This makes it similar to your teeth. Once you lose a tooth, you will never grow a new one.
    Elephants use their tusks to protect themselves, lift things, dig water and gather food. But losing the tusk will not kill them. The way in which they lose the tusk is what matters. Usually, people get tusks by culling (限量捕杀), which means killing old and weak elephants. They also take tusks from the elephants that have died naturally.

    However, these sources aren't enough to keep up with the demand for ivory. Therefore, some poachers (偷猎者) kill healthy elephants and cut their faces open to remove the tusks. About 27,000 elephants are killed by poachers each year, according to National Geographic.
    As a result of poaching, some African elephants gradually evolved (进化) without tusks, which has allowed them to survive. In Mozambique, about 90 percent of African elephants were killed for their tusks and meat from 1975 to 1992, National Geographic reported.
    Scientists found that about a third of younger females—the generation born after 1992—never developed tusks.
