Can we make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. They say that in a film or on TV you may see elephants, monkeys, dogs or some other animals doing a lot of things. If you watch carefully, you may find those animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some easy work if they know they will get something to eat. We all know elephants can carry large logs and dogs can look after houses. And we can even teach animals to work in factories. In America, for example, people use apes to help make cars. Scientists think that those big monkeys may, one day, drive trains. Now people are trying to let them do something just like man. We can use dogs to _ . A) drive trains B) help make cars C) keep the houses safe D) carry logs

Rather than talk about how he feels, often a man would express his love by buying the woman cosmetics , or bringing home a flower, or giving up the control of the remote . And when men do talk, they'd prefer to talk about actions rather than emotions. For example, a lot of men would choose to express their long-range faith in a relationship by talking about next summer's vacation plans, not by starting a conversation about undying love. Men just prefer to say their plans with plane tickets, rather than poetry. It's one of the reasons why men are more comfortable talking at work (the practical world) than they are at home (the castle that emotion built). But you can bring out his great communicator by making him feel more like he's operating in the work mode, even when the topic at hand is your love life. When men talk less and women want more, the conflict can _ . Like when a policeman is questioning an unwilling witness, more silence equals more questions. A full 65 percent of men we surveyed recently told us that they don't want their partners to ask them more questions about themselves. It's clear that some men are just tired of feeling like they're on the witness stand. They're not necessarily hiding anything; many men simply prefer not to have to tell confusing feelings that they may not even understand themselves. An age-old method can make things better: back off a little, give him room to operate in a conversation, and he's more likely to open up. According to the author, men feel more comfortable when talking _ . A) actions B) feelings C) long-term friendship D) conversations

Q: Most academics would view a post at an elite university like Oxford or Harvard as the crowning achievement of a career--bringing both honour and access to better wine cellars. But scholars desire such places for reasons beyond glory. They believe perching on one of the topmost branches of the academic tree will also improve the quality of their work, by bringing them together with other geniuses with whom they can collaborate and who may help spark new ideas. This sounds reasonable. Unfortunately,as Albert Laszlo Barabasi of Northeastern University,in Boston (and also, it must be said, of Harvard), shows in a study published in Scientific Reports, it is not true. Dr Barabasi and his team examined the careers of physicists who began publishing between 1950 and 1980 and continued to do so for at least 20 years. They ranked the impact of the institutions these people attended by counting the number of citations each institution's papers received within five years of publication. By tracking the association of individual physicists and counting their citations in a similar way, Dr Barabasi was able to work out whether moving from a low to a high-ranking university improved a physicist's impact. In total, he and his team analysed 2,725 careers. They found that, though an average physicist moved once or twice during his career, moving from a low-rank university to an elite one did not increase his scientific impact. Going in the opposite direction, however, did have a small negative influence. The consequence is that elite university do not,at least as far as physicists are concerned,add value to output. That surprising conclusion is one which the authorities in countries such as Britain, who are seeking to concentrate expensive subjects such as physics in fewer, more elite institutions--partly to save money, but also to create what are seen as centers of excellence--might wish to consider. On what basis did Dr Barabasi's research team draw conclusions that getting a post at a higher-rank university won't help scholastic impact? A) His team examined the 20-year careers of physicists. B) He came from Havard, a top-ranking university himself and knew it well. C) Individual physicists' citations by other authors increased within 5 years. D) They ranked the physicists' institutions according to citations to these universities' paper.

Switching telephone providers used to be the only way homeowners could save money on telephone bills. Now thanks to new technology, comsumers have another choice-making phone calls over the internet. And this can be completely free if you call another person with an internet phone set-up. The technology is called voice over internet protocol , or VoIP. In 2005, consumer demand for VoIP dramatically grew. In the US, where popularity has grown faster than here in the UK, 8.4 million are predicted to subscribe this year. For the past couple years, VoIP pioneers such as Skype have accounted for the majority of internet phone subscribers. VoIP is attractive to consumers because it's cheaper than traditional phone services. With the basic equipment of PC, microphone and headset, and VoIP software and broadband internet for optimum voice quality, consumers can save a fortune chatting for free to other internet phone owners and save money calling regular landlines . But, as the saying goes, . Many of these services suffer from uncontinuous lapses in quality. While some users may tolerate echoes or a dropped call, improved quality is needed to attract more customers. Computing has examined the benefits of using a PC as a telephone with VoIP in how easy they were to set up, how effective they were and the range of their features. Skype(www. skype.com) came top for its bother-free approach, easy set-up and exceptional voice clarity. Sipgate (www. sipgate. co. uk), MSN(www. messenger. msn. co. uk) and Yahoo! Messenger (uk. messenger. yahoo. com) provide an audio "wizard" that improves sound levels. Google Talk (www. google. com/ talk) was less helpful and Babble. net (www. babble. net) was let down by its poor help files. Yahoo! Messenger provides some of the best features, including the option of landline calls, webcam chats, instant messaging, voice-mail and conference calls. Which of the following statement is true according to the passage? A) Sipgate is less helpful. B) Yahoo! Messenger offers some best features. C) Skype is the best one in the new technology. D) Google Talk provides very good audio "wizard".
