With the development of modern technology, people can stay     1     (connect) with their families and friends easily, however far apart they are from each other. WeChat is one of the most     2     (frequent) used means of communication in China. It is reported that the number of the WeChat users     3     (reach) over 1.1 billion so far.

Once joining the WeChat, people can find more and more people start to add them     4     fiends. They don’t have to consider time     5     (zone) when communicating. Another reason why it is so popular is that it costs nothing. It’s also very convenient for people to immediately update     6     they are doing by WeChat.

However, addiction to WeChat will rob people of the time that should otherwise     7     (spend) on something more important. And the many so-called friends on it are not really friends at all, who simply want     8     (put) ads or sell items on Moments. Besides, people on the WeChat are more likely to compare     9     (they) with others, which will make them feel bad when finding some people seem to be     10     (success).

In much of Asia, especially the so - called “rice bowl” cultures of China, Japan, Korea,     1     Vietnam, food is usually eaten with chopsticks.

    2     (chopstick) are usually two long, thin pieces of wood or bamboo. They can also     3     made of plastic, animal bone or metal. Sometimes chopsticks are quite artistic. Truly elegant chopsticks might be made of gold and silver with Chinese characters. Skilled workers also combine various hardwoods and metal     4     (create) special designs.

The Chinese have used chopsticks for five thousand years. People     5     (probable) cooked their food in large pots,     6     (use) twigs (树枝) to remove it. Over time, as the population grew, people began cutting food into small pieces so it would cook more quickly. Food in small pieces could be eaten easily     7     twigs which gradually turned into chopsticks.

Some people think that     8     greatest Chinese scholar Confucius, who lived from roughly 551 to 479 B.C., influenced the     9     (develop) of chopsticks. Confucius believed knives would remind people of killings and were too violent for use at the table.

Chopsticks are not used everywhere in Asia. In India, for example, most people traditionally eat with     10     (they) hands.

I’m    1    only daughter of my parents. So they are worried     2    everything I do. For example,    3    I ride my bike, my parents won’t let me     4     (ride) by myself. They are afraid I might fall off my bike and hurt    5    . They are taking great trouble to support the bike, with my mother even     6     (carry) a first-aid box. I’m not free to ride and I often say    7     (angry), “Why not let me ride alone?”

Now, most families have one child.     8    (Parent) want to do everything for their children. This does no good to them. Too much love from parents may prevent children from     9    (be) independent. In my opinion, parents should let their children do    10     they should do alone.

Big challenges, however, can sometimes lead to great     1    (solution). In the 1950s, the Egyptian government wanted to build a new dam     2    (cross) the Nile in order to control floods, produce electricity,     3     supply water to more farmers in the area. But the proposal     4    (lead) to protests. Water from the dam would     5    (like) damage a number of temples and destroy cultural relics that     6    (be) an important part of Egypt’s cultural heritage. After     7    (listen) to the scientists     8    had studied     9    problem, and citizens who lived near the dam, the government turned     10    the United Nations for help in 1959.

Hol Xil or Kekexili is the world’s third     1    (large) uninhabited (无人居住的) area. Many examples of wildlife can     2     (find) in the remote area of the Qinghai-Tibet plateau. The view of mountains, glaciers and lakes here     3    (make) it a good place in terms of natural beauty.

At the 41^st session of the UNESCO World Heritage Committee     4    (hold) in Poland, Hol Xil was approved as a new world heritage site, becoming the 51^st world heritage site in China. It is home to more than 230 species of wildlife,     5     (include) the endangered Tibetan antelope. The illegal hunting of Tibetan antelope used to be     6     serious problem in the 1990s. The wool of Tibetan antelopes, soft and warm, can be obtained     7    hurting the animals. But poachers( 盗猎者) would choose simply to kill them before taking the wool,     8     caused the number of Tibet antelopes to drop rapidly. The struggle to stop     9     (legal) hunting was described in the 2004 film Kekexili : Mountain patrol.

Now that Hol Xil has made it onto the UNESCO list, it is believed that the     10    (protect) of the region’s wild animals and special ecosystem will be more effective.

Sending gifts varies greatly from country to country. In Australia, Canada, the United States    1     European countries, sending gifts     2     (be) rarely expected. While seen as a nice gesture, it is more important to avoid    3     (give) highly personal gifts such as clothing. When visiting the home of a colleague from one of these    4     (country), it is normally appropriate to bring a gift to the hostess.

In America, expensive gifts are    5     (definite) out. A good choice is to take the deserving person to dinner, or to an entertainment or a sporting event.     6    the contrary, gift giving is a traditional custom in Japan. In Japan the proper gift is thought    7     (express) the giver’s true friendship, gratitude and respect far    8    (well) than words can. So if you plan to visit Japan or to have any Japanese visit you here, be prepared.

Australia is known for     9    (it) friendliness and informality. So modest gifts, such as a diary, a paperweight, or a coffee cup might be presented to a friend. But when visiting a German home, gifts    10     reflect your home country are popular, and you might want to bring small gifts for the children of the family you are visiting.
