They believe that traveling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike traveling also have some reasons. Traveling, in my opinion, dose more good than harm. Most importantly, it broadened our mind. We can get in touch with othercivilization , culture, customs and ideas. Through history, most people traveled because of necessity --not for pleasure. People traveled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever traveled just for the fun of it. In ancient times, for example, rich Romans traveled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity. They wanted to find out what it looked like beyond the horizon . Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures. So, traveling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it. Question: What's the main idea of this passage? - Different kinds of traveling. - Traveling enriches our mind. - Ways to enjoy yourself while traveling. - The advantages and disadvantages of traveling.
Traveling enriches our mind.

The teachers are graded on categories such as "motivated", "good instruction," "easy examinations", or even "sexy." Many teachers think that their privacy has been violated. The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction.Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers.On a grading scale of one to six, the teachers' average grade is 2.7 and it has been improving lately.He often says the impression is that students are bullying their teachers.But there is also bullying of the students by teachers. "Teachers must also learn to live with criticism," he added.But still, the website is not totally immune from manipulation , as one teacher near the northern city of Hanover recently proved.He registered himself on the website as a student and then rated his own teaching colleagues highly.Within a few days, seven of his colleagues were listed in the top 10 rankings of Germany's best teachers. Question: The founders of the website intended to_. - get the students to know their teachers better - conduct a survey on teachers' performances - help the teachers to improve their teaching - change the teachers' ways of giving instructions

Read the following article and select the best answer. Article: Advertising gives useful information about which products to buy. But modern advertising does more than gives news about products and services. Today's advertisements, or ads, try to get consumers to buy certain brands. Writers of advertising are so skillful that they can, sometimes persuade a consumer to wear a certain kind of clothing, eat a special kind of cereal, or see a movie. Consumers might never even want a product if they did not see or hear advertisements for it. For example, you probab1y do not need the newest cereal in the supermarket. There are probably many cereal brands on your kitchen shelves. You may not have space on a shelf for another. But if you see ads about a new cereal that is your extra-tasty and has a free prize in the box, you may want it. Advertising must get attention. To be effective, it must be exciting, entertaining, or provide some pleasure. The secret of writing good advertising copy is to offer a good idea as well as a product. The idea is what the ad is really selling. One example is an ad that says eating a certain cereal will make a person do well in sports. That cereal brand may sell better if consumers think it offers strength and energy. Question: According to the passage, a good advertisement should _ . - be both persuasive and effective - give people useful information - show people a product - show people a new idea of a product
be both persuasive and effective

The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age. The largest study of the effects of aging on the heart has found that women's _ may be linked to the fact that their hearts do not lose their pumping power with age. "We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age," said the head of the study, David Goldspink of Liverpool John Moores University in the UK. "Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men," said Goldspink. "This is part of the aging process." What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's. "This gender difference might just explain why women live longer than men," said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. "The team has yet to find why aging takes a greater loss on the male heart," said Goldspink. The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age. Question: The text mainly talks about _ . - men's heart cells - women's aging process, - the gender difference - hearts and long life
