Question: Article: At first, the earth's surface layer was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil. There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks in the rock, which become bigger and finally the rock breaks up into smaller pieces. The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces. The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.
Answer: forms very slowly

Answer: According to the passage, soil _ .

Question: Article: Right now in China, talks on the street have been about the strange weather and it's raising a lot of concerns. A heavy haze has blanketed many cities in the northern and southern parts of the country in part of an unusual weather system that's descended on the nation. The haze stretches over a vast area, from Hebei and Shan-dong Provinces in the north all the way to Zhejiang, Anhui, Jiangsu, Hunan and Fujian provinces in the south. At its worst, the smog is reducing visibility to less than 200 meters and disrupting traffic, both on the ground and in the air. The weather front has also led many to worry about the possible health impacts. Many cities are waking up to another day covered by a dense haze. In Beijing, drivers have to keep their lights on even though it's already past eight o'clock in the morning. Even driving at very slow speeds, the roads can still be very dangerous. In some of the worst hit areas, drivers can't even tell the colors of traffic signals. Authorities have stepped in to close off many highways across the troubled region. In Shandong Province, the highways that are open are backed up for miles. And traffic police have stepped up their patrols. In the region's airports, flights information boards have gone red. A huge number of flights have been delayed or cancelled, nearly three hundred in Beijing alone, leaving thousands of passengers stranded. Some are more frustrated than impatient. Passenger from Jinan airport, Shangdong province, said: "I've been waiting for more than five hours. It's Mother Nature, so there's really nothing we can do." The airport is urging passengers to confirm with their carrier whether their flight will still take off as scheduled. Back on the city streets, people are wearing breathing masks to get free from any ill effects. Fog has cleared a little in Shanghai. But damage has already been done. Shanghai resident said: "I've been wearing the mask, but still, my throat feels sour and itchy. I think it's because of the weather." The weather forecast predicts a cold front is about to sweep across central and eastern China tomorrow. Many are hoping that this will clear away the depressive haze as well as the harm it brings.
Answer: heavy fog

Answer: The harm the smog caused didn't include _ .

Question: Article: After finishing my teaching for a school year, I thought that I should go back to Montreal, Quebec, my hometown for a visit. My main goal was to relax in preparation for the challenges of my retirement in the coming year. Through my stay in Montreal, I met lots of Chinese who are struggling to succeed and then lead a better life in Canada. Some travelled thousands of miles to get knowledge. When I spoke with some of them about the major barrier they had to face after they arrived in Canada, they all talked about the two official languages of Canada. But I was impressed by their ability to express their ideas while switching between English and French. Almost all of those people said they often felt homesick. They miss their families and friends. Though Montreal has lots of Chinese restaurants, they long for a home-cooked meal. I met some tourists who were trying to realize their childhood dreams of experiencing the life in a developed country. When I asked them if Montreal had lived up to their expectations, they hesitated. They said that reality never agrees with fantasies. However, they were glad to have the opportunity to visit Montreal and didn't regret taking the trip. Not all the Chinese people I met were happy. I once met a young lady who met with a gentleman through the Internet. However, to her disappointment, he disappeared after he promised to marry her in Montreal. I was served by another Chinese person who could not handle the challenges of studying in an English environment and ended up working in a restaurant with minimum pay. Exploring different parts of the world, without any doubt, is an enriching experience. However, one should be realistic when it comes to leaving his hometown to set up a new life in a foreign country. One should take the time to examine the advantages and the shortcomings of the venture before they decide to chase an uncertain dream of achieving success or leading a better life.
