    We can see many people riding shared bikes in China now.

    Bike-sharing helps people to borrow a bike from one place and return it at another place easily.

    This kind of bike has GPS or Bluetooth on it. You must have a smart phone if you want to use it. First, you have to download (下载) an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan (扫描) the QR code on the bike and you will get the bike.

    Then you can enjoy your trip. What's more, you can easily find one and don't have to worry about where to park it. Every hour you ride, you need to pay only one yuan. It doesn't cost so much, does it?

    Science changes our lifestyles. Bike sharing makes our life easier. And we also hope that people can not only enjoy it but also put it to good use.

回答下面5个问题,每题答案不超过5个词。

    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.

    There are many times we need to give gifts. Keep these tips in mind as you're thinking about what gift you'll give.

    Gift giving dos

    Leave the price label in the bag if it is an expensive gift so that others can see how much they need to give back. Remember to hold the gift in both hands to give gifts.

    Gift giving don'ts

    Don't worry about what card to take with the gift. Cards are seldom used in China, so a Chinese wouldn't expect a card along with a gift.

    Choosing the right gift

    Gifts for family

    When you're meeting your partner's family, a gift is expected, food or fruit baskets are good if you have no idea what to give. If your hometown is known for a special food, buy some to take as gifts.

    Gifts for friends

    You can spend less money on friends than you do on family. Books, wallets, key rings and special foods like chocolate or coffee are good enough.

    Gifts for business partners

    When you're starting a business relationship, a tasteful gift will be better. Pens from your company or with the receiver's name is a practical gift. Local snacks from your area is a great gift too.

    Gifts to avoid(避免)

    You should remember not choose anything because of the cultural symbolism(文化象征) or the word shares a similar pronunciation to some bad things. Clocks, in Chinese, to give a clock has the same pronunciation as the phrase "songzhong". Umbrellas and shoes are not good gifts in China.

    In all, a thoughtful gift is great when you want to thank a friend, say goodbye to someone or meet families.
