Ques: Psychologists tell us that there are four basic stages that human beings pass through when they enter and live in a new culture.This process begins with the "honeymoon stage".This is the period of time when we first arrive in which everything about the new culture is strange and exciting.We may be suffering from "jet lag" but we are thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kinds of food.This stage can last for quite a long time because we feel we are involved in some kind of great adventure. Unfortunately, the second stage can be more difficult.After we have settled down into our new life, we can become very tired and begin to miss our homeland and our family, friends, pets.All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture.This period of cultural adjustment can be very difficult and lead to rejecting or pulling away from the new culture. The third stage is called the "adjustment stage".This is when you begin to realize that things are not so bad in the host culture.Your sense of humour usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place.Things are still difficult, but you are now a survivor! The fourth stage can be called "at ease at last".Now you feel quite comfortable in your new surroundings.You can cope(deal) with most problems that occur.You may still have problems with the language, but you know you are strong enough to deal with them. This passage mainly talks about _ . A) culture and foreign language learning B) adventures in a foreign land C) getting used to a new culture D) the interaction of different cultures
Ans: C

Ques: Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better. In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully. Sounds is measured in units called decibels . At a level of 140 decibels people feel pain in their ears. Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well. There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to a society that has already faced enough stress. Why does the passage say peace and quiet are becoming harder to find? A) Because the world is making more and more noise. B) Because wars and battles happen here and there in the world. C) Because all the sounds are becoming over 140 decibels. D) Because some machines can make noise.
Ans: A

Ques: The Chinese invented paper in 105 A. D. They mixed the bark of a tree and rags with water, put a screen into the mixture, and lifted out a thin piece of wet paper. They dried the paper in the sun. The Chinese kept their secret of how to make paper until a war with Muslims in the ninth century. The art of papermaking soon spread throughout the Muslim world. The Mayan Indians in Central America and Pacific Islanders also discovered how to make paper, but their knowledge never spread to the rest of the world. For centuries, all paper was made by hand. Rags were the main material. Then a French scientist discovered that people could make paper from wood, too. Finally, in the eighteenth century. a Frenchman invented a machine to make paper from wood. Who discovered how to make paper? A) The Chinese. B) The Pacific Islanders. C) The Mayan Indians. D) All of the above.
Ans: D

Ques: If you've ever seen the way dog people interacted with their pets, it comes as no surprise that there's some germ-exchanging going on there. A new study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes live on your skin. A team of researchers led by Se Jin Song at the University of Colorado, Boulder, took swabs of the tongues, palms, forehead and feces of members of 60 family households. Some of the families had children or household pets and some did not; dogs were the only pets swabbed. Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly, family members who lived together had more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households, probably because we pass microbes through the air, through direct contact, and via the surfaces we touch. The most surprising finding, however, was the large bacteria contribution Fidonad made. The skin bacteria of dog owners from different households was almost as similar as if they'd cohabited without a dog. Put another way, you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does. The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human skin. One in particular, a family of bacteria called Methylophilaceae, was abundant in the mouths of dogs sampled as well as the skin of their owners--indicating "a common occurrence of oral-skin transfer between dogs and their owners," according to the results published in the journal eLife. What does this passage mainly tell us? A) It is unsafe to keep dogs because of microbes. B) How many kinds of bacteria live on people's skin because of dog ownership. C) Dog ownership affects the kinds of microbes living on people's skin. D) What are the similarities between people who keep dogs and those who don't.
