Man is a land animal, but he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient way to travel to many parts of the world. Today, nearly two—thirds of the world’s population live within 80 kilometers of the sea coast.
In the modern technological world, the sea offers many resources to help mankind survive. Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
The list of riches of the sea yet to be developed by man’s technology is immense. Oil and gas explorations have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined.
Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (贝类动物) is an ancient skill practised in the past mainly by Oriental people.
Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy.
Technology is enabling man to explore ever more deeply under the sea. The development of strong, new materials has made this possible.
The technology to harvest the sea continues to improve. Experts believe that by the year 2020 the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea will be largely solved.

For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall．Soon, that will change．Electronic commerce （trade） is growing fast and will soon bring people more choices．There will, however, be a cost: protecting the consumer from being cheated will be harder．Many governments therefore want to apply street regulations to the electronic world．But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation．
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything for the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty．But governments cannot enforce national laws on businesses whose only presence is on the screen．Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund for a clothes purchase．
One answer is for government to cooperate more: to recognize each other’s  rules．But that requires years of work and volumes of detailed rules．And plenty of countries have rules too fanciful for sober countries to accept．There is, however, another choice．Let the electronic businesses do the regulation themselves．They do, after all, have a self-interest in doing so．
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset．Governments, too, may compete to be trusted．For instance, customers ordering medicines on-line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead．
Customers will still need to use their judgment．But precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort．And the new technology will also make it easier for them to complain when a company lets them down．In this way, at least, the advent of cyberspace may argue for fewer consumer protection laws, not more．
【小题1】According to the author, what will be the best policy for electronic commerce?

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
【小题1】 What does "these two killers" in the second paragraph refer to? 

Every year mobile phones develop. Imagining what they will look like and be able to do in 2020 is really a challenge. To help, experts have outlined three major mobile trends that they believe will have become reality by then.

Our phones will be so smart in 10 years’ time that they’ll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there’s a road accident up ahead.

The second trend is in gesture-based controls. People who know the iPhone’s touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It’s believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear.

The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these—cameras, music players and game consoles—will be wirelessly connected. Mobile phones won’t need to contain these devices because users will be able to control them wirelessly through their phones.

The first paragraph serves as          .

A. a lead-in        B. a conclusion      C. a summary         D. a supporting fact

Which of the following is most likely to be the appearance of a mobile phone in 2020? 

A. drive cars for us                             

B. be controlled by the users’ voices

C. be controlled by home appliances

D. be very big together with separated multiple parts

The text mainly tells us          .

A. three major trends of mobile phones  

B. what mobile phones will look like in 2020

C. the future mobile phones are gesture-based

D. some new functions of the present mobile phones

The Apple iPhone’s impact was widely evident (明显的) at the Consumer Electronics Show, as new touch－screen devices could be found everywhere.

The consumer electronics industry came unbuttoned in Las Vegas this week. At the annual Consumer Electronics Show, companies from around the world unveiled many devices boasting (以拥有…而自豪) touch – sensitive technology, rather than traditional push-button controls.

Motorola, Sony, and LG Electronics all showed off touch-screen phones this week. Microsoft Chairman Bill Gates praised and offered a touch-screen computer, the Surface, related to a flat panel TV for a tabletop. Even camera makers, such as Kodak，included touch-screen LCDs in their devices. Touch-screen tech has been in use for years，but the push to develop and weave it into consumer electronics gathered steam with the June introduction of Apple’s iPhone. “The touch-screen industry is really getting hot,” says Jennifer Colegrove, a senior analyst at iSuppli. “Since the iPhone came out, there are a lot of companies that did not have a relationship with touch screens before that decided, ‘OK, I want to make a touch screen, too.’”

The touch－screen tech ecosystem now includes more than 100 companies specializing in everything from smudge-proof (防污的) screens to sensors (传感器) able to detect fingers before they even contact the screen. Sales of leading touch-screen technologies，such as those used in mobile phones and navigation (航行) devices，are expected to rise to $ 4.4 billion in 2012, up from $ 2.4 billion in 2006，according to iSuppli estimates.
