Besides providing a perfect environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy.
The most obvious movements are the waves and the tides. Winds cause the waves, and the gravitational pull of the moon and the sun causes the tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet.
France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity. Waves and tides are caused by ________ .
| A．the same forces | B．different forces | C．their own movements | D．plants and animals |
It can be inferred from the passage that __________ .
| A．waves as well as the energy in the tide can produce electricity |
| B．the highest tide is 40 feet higher than the lowest one at the sea |
| C．many countries in the world have made the most of energy produced by seawater |
| D．it is being tried in some developed countries to use energy in the tides to produce electricity |
The best title for the passage is ______.
| A．Tides and Waves | B．How to Produce Electricity | C．Seawater | D．Another Cheap Energy |
IMAGINE if there was a device that could do everything for you – wake you up every morning, chat with you and type your e-mails.
The piece of technology in question would be smart, able to tell you about the weather and where the nearest restaurants are.
The good thing is you no longer need to wonder, because something like this already exists. And its name is Siri.
Siri is a voice recognition application designed for Apple products and the concept has been around for almost a year.
When Siri first came out it could only speak English, but now it has “learned” lots of new languages, including Chinese, Cantonese and Taiwanese, reported The Wall Street Journal. So, you can give it orders in your mother tongue.
But how could a cell phone or a computer “hear” what you are saying and understand it? This is all because of voice recognition technology.
When you speak, your voice creates vibrations (振动) in the air – a bit like waves in the water when you throw a rock into the lake. The microphone receives the vibrations and the computer changes them into digital data that is then divided into many parts. They are analyzed one by one to see what pronunciations each part stands for. The computer then puts these pronunciations together into possible words according to its built-in dictionary.
But figuring out the words is far from enough; building words into meaningful sentences is the most difficult part. The computer has to compare what it hears to a large library of known phrases and sentences to determine what the user is saying.
However, people don’t always talk in the most standard way and sometimes make grammatical mistakes. This is why traditional voice recognition software always requires you to remember keywords and to speak in a certain way.
Fortunately, Siri isn’t like that. It’s not just “voice recognition”; it’s “natural language understanding (NLU)”. You can ask it things like “Do I need an umbrella today?” and it will know that you are asking about the weather, according to ABC News.
“The key thing is NLU – understanding what you mean and what you want,” Neil Grant from Nuance, a software company in the US, told The Guardian. “Historically, you had to learn a huge long list of commands . As NLU progresses, you can say what you want in a way that’s natural to you.” What is the function of the first two paragraphs?
| A．To show that invention usually results from need. |
| B．To clear doubts about voice recognition technology. |
| C．To introduce something that offers these helpful services. |
| D．To show how the voice recognition works. |
Which step is the most complicated in the process of voice recognition according to the article?
| A．Changing the received vibrations into digital data. |
| B．Analyzing the digital data to see what pronunciations it represents. |
| C．Putting the pronunciations together into possible words. |
| D．Figuring out meaningful sentences based on the words. |
How can you get Siri to respond according to the article?
| A．You can speak in a natural way as you would to a person. |
| B．You can only speak English and Chinese. |
| C．You have to say things in a certain way. |
| D．You have to remember keywords and speak specific commands. |
What can be concluded from the article?
| A．Siri can record and save what you say frequently into a computer dictionary. |
| B．Siri will fail to understand what you say if you make grammatical mistakes. |
| C．The biggest advantage of Siri is that it’s NLU is rather than just voice recognition. |
| D．Since first applied to Apple products a year ago, Siri has made great improvements. |
The text is mainly about ________.
| A．the convenience of future life. |
| B．an introduction to the Apple products. |
| C．the working system of voice recognition |
| D．the introduction to Siri |
Does being rich make you happy? Many studies on happiness give negative answers. Here are some points in being happy.
Basic Human Needs Must Be Met
People whose basic needs for shelter, clothing and food are not met will find it very difficult to feel happy. Of course, there are exceptions, but for most of us, we can only be happy once our basic needs are met.
The Joneses Cannot Be Escaped
People’s happiness is not determined by how much they have, but by how much people around them have. So, we tend to feel happy once our basic needs are met and we have more than the people surrounding us.
This means that while keeping up with the Joneses could be destructive if we let it go too far. It is also part of humana nature to want to feel at least on the same level, financially, as those surrounding us.
You Should Escape The Rat Race
We should know the importance of staying out of the rat race. So yes, you need to work hard, get the education you need to land a good job and work long enough and hard enough to get to a place where you can easily meet your basic needs. What are basic needs? For most middle or upper middle class Americans, basic needs are not very basic anymore.
For most of us, once our basic needs have been met, happiness is achieved when we engage in activities we like, spend time with friends and family and stay active. Making money for the sake of making money does not make people happy.
Ideally, these questions should be answered when you’re still young and just starting out. Don’t wait until your midlife crisis to realize that half your life has passed you by and you’re still unhappy.What’s the main idea of the passage?

Competition between international universities is heating up, as China grows as one of the largest exporters of students aiming to study abroad. “Lots of universities are becoming more and more aggressive to attract Chinese students. Every day I receive contacts from universities in the US expressing the desire to come to China to recruit students,” said Frank Joseph, a commercial officer from embassy of the United States.
One key reason why more Chinese students are able to study abroad is the economy: With China’s boom within the past decade, more families have the financial wherewithal(资金) to send their children to international universities. There will be a total of 200,000 family-funded Chinese students studying overseas in 2009, up 20 percent from last year, said Wu Zaofeng, deputy secretary general of China Education Association for International Exchange.
International institutions, Joseph said, are also facing increasingly tough financial situation with a shortage of domestic students and a drop in government subsidies(补贴). Students, especially in the US are paying high tuition fees and living expenses. Chinese students with money to spend, according to experts, can fill up the gap. Students on average spend 150,000 yuan to 200,000 yuan every year studying in US, according to statistics from the US Institute of International Education. During 2007-2008, there were approximately 81,000 Chinese students studying in the US, up 19.8 percent from 2006.
Representatives from approximately 60 universities from the United States are planning to arrive in Beijing this weekend to attract more Chinese students at this year’s fair. Besides the US, many other countries are also vying(竞争) to enroll Chinese students.
Post-study work visa put out by British government allows all international students completing a UK degree qualification to apply for a visa to stay on and look for work in UK for up to 2 years. Being the third most popular destination for international students next to the US and the UK, France has set up two types of scholarships and has handed out an increase of 26 percent in scholarship funds to Chinese students in recent years.The reason for heating up competition between international universities is ___.
| A．that China has become one of the largest exporters of the students aiming to study abroad |
| B．that the students in China are becoming richer and richer |
| C．China’s boom, the students’ desire and foreign universities’ commercial motive |
| D．that the students in foreign countries do not want to go to universities |
Why are more Chinese students able to study abroad?
| A．Because they can’t go to the best universities at home. |
| B．Because their families have enough money to send them to international universities. |
| C．Because they want to win the scholarship of foreign universities |
| D．Because the Chinese students enjoy following others and they want to be independent. |

When I was in medical college, I went camping with some of my friends. The season was summer; therefore, we chose to go to the seaside. After arriving there, we rent a room and left our luggage there. We finished lunch and then decided to rent a boat because the sea and the weather were beautiful.
We started to row, but about one mile out, the weather suddenly changed. Although the weather was not good, we didn't want to give up, but finally my friends and I agreed that we should go back. We tried to change the boat's direction, but as soon as we changed it, the oarlock (桨架)broke. Therefore, we were unable to turn back. We had to wait for help because we couldn't do anything.
