【题目】Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.

Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.

Since 1960 a new kind of tool has appeared. This is the silicon chip (硅芯片). It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it?

Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?

【题目】Reducing the amount of salt in our diets could save nearly 20,000 lives in the UK every year, according to researchers.

The recommended maximum daily intake for adults is 6g in the UK, although just month the World Health Organization (WHO) revised this down to 5g. Yet according to figures from the British Heat Foundation, men consume around 9.7g a day, while women have 7.7 g.

Fast food

Salt Content

Original chicken

2.9g per portion (份)

Spicy crayfish

3.5g per portion

Large chips

1 per portion

McDonalds Big Mac

2.1 per portion

Not researchers at three universities, including Harvard Medical School, have revealed the dramatic effect reducing salt could have on death rates by using computer models. They estimated that reducing salt intake to 6g would save 500,000 to 850,000 lives in the US over the next decade.

British doctor Ian Campbell, medical director of charity Weight Concern, told Mail Online: Salt is a big problem in the UK, too. Its a silent killer. Over time consuming too much of it increases the risk of high blood pressure, which can lead to heart attacks. About 80 percent of our salt intake comes from processed foods, so it can be difficult to avoid.

Many people are unaware of where salt is hidden, such as bread, soups, ready meals, and even breakfast cereals (麦片). The government approach has been to encourage food companies to cut the amount of salt in their products. There has been a reduction but it is taking too long. The Food Standards Agency should consider setting compulsory maximum levels for salt.

Victoria Taylor, Senior Dietitian at the British Heat Foundation, added: Eating too much salt may raise your blood pressure and having high blood pressure increases your risk of developing heart disease.

The government has worked with the food industry to reduce the amount of salt in our food and make labels clearer. But there is still work to be down by everyone because the majority of Brits are still consuming more salt than they would be.
