Even if trees cannot walk, they are still on the move.

In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra (冻土地带)starts has been shifting northward. Trees growing along the tree line must protect themselves from the cold wind. To do this, plants tend to grow horizontal (水平的)branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.

But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all the leftover energy. these trees have started producing more seeds. This happens especially in places where the white spruce (白云杉)grows.

White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When wind-blown seeds end up on the tundra beyond the tree line, they eventually can sprout (发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.

New trees will provide shelters for some snow, keeping the sun’s rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below,which encourages trees to grow. The recent rise of temperature has helped more trees grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about impacts on the animals that depend on frozen conditions for food and shelter.

1.What is the main cause of the trees in the Arctic moving northward?

A. The rising temperature.

B. The shrinking of northern tundra.

Not having done physical exercise for some time, I found myself a little low-spirited and couldn't study efficiently, so I decided to do some running the next day. At 6:15 the next morning, my alarm clock rang. Unwilling to rise from my bed, I turned it off and went back to sleep. However, 5 minutes later, I struggled to get up. After washing and brushing, I had my sneakers on and went out.

Wow! The air was so fresh that I couldn't help breathing it deeply. I stretched (伸展)my arms and legs, then started to run. I found all things around me were so attractive. Look, the branches were waving, as if they were welcoming me; the blossoming flowers were bowing, with shyness, just like girls. Listen, the wind was whispering, as if to say “come on, girl”. What's more interesting was those two birds, perching in the tree. They were scared and flew away when I passed them. “Hey, chaps, relax.” I shouted without stopping running. “Let's enjoy the beautiful morning together!” Then miracle(奇迹) happened. The two little creatures seemed to understand what I said. They turned back and twittered(吱吱叫) around me. “Are you singing for me?” I asked. They twittered again and again, sounded like “Yes”. I was delighted to hear that. Ah, what a wonderful morning and how beautiful life is!

Actually, there are a lot of charming things around us. Helen Keller wrote in her famous article Three Days to See, “The seeing see little”. Indeed, many of us ignore the beauty around us, just because we are familiar with them. They always complain that life is boring. But, I just want to say, if you live each day with appreciation of things around, you'll find life is very charming. So, let's enjoy life from now on.

A new pollen (花粉) study showed that drought was responsible for the extinction of civilizations more than 3,000 years ago during the Bronze Age.

The reason behind why the civilizations in and around modern-day Israel suddenly broke down more than 3,000 years ago has remained a mystery up until now. A new pollen study by Tel Aviv University researchers finally solved this Bronze Age mystery.

Prof. Israel Finkelstein showed that owing to serious climate changes, the entire world of the Bronze Age crumbled in a short period of time. The discovery was made on the basis of a high-resolution analysis of pollen grains taken from sediments (沉淀物) beneath the Sea of Galilee and the western shore of the Dead Sea.

Prof. Finkelstein received support from the European Research Council to conduct research aimed at reconstructing ancient Israel. Researchers of the part of the project that dealt with climate change extracted (提取) about 60 feet of samples of gray muddy sediment from the center of the Sea of Galilee in northern Israel. They had to drill through 1,000 feet of water and into 65 feet of the lake bed and were able to recover evidence dating over the past 9,000 years.

“Pollen is the most enduring organic material in nature,” explained Dr. Dafna Langgut, a pollen researcher who carried out the actual work of sampling. “These grains tell us about the plants that grew near the lake in the past and therefore prove the climatic conditions in the region.”

Researchers noted a sharp decrease in Mediterranean trees like oaks and pines in the Late Bronze Age. According to study experts, this could be because of repeated periods of drought. The droughts may have resulted in long famines, forcing people to migrate from north to south.

B. climate change was to blame for the lost civilization

C. people in the Late Bronze Age starved to death

D. droughts were rare during the Bronze Age

4.The text is most probably taken from _____.

A deal has been signed to turn by-products from a Scottish distillery(酿酒厂)into fuel for cars.

In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin-out company from Napier University in Edinburgh. They plan to use bacteria to feed on the "leftovers" from the whisky(威士忌酒)making process. This will produce butanol which can be used to fuel vehicles.

More than 90% of the stuff that comes out of a whisky distillery is not whisky. It is leftovers like draff and pot ales(酒糟)— both produced in the early stages of the process. They are high in sugar and are currently used for things like fertiliser and cattle feed. Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by-products to produce butanol—a direct replacement for vehicle fuel. Now the spin-out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement. Together they will apply the process to thousands of tons of the distillery's leftovers.

Professor Martin Tangney, founder of Celtic Renewables, said "Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries — whisky and renewables. This project shows that creative use of existing technologies can utilize resources on our doorstep to benefit both the environment and the economy."

Douglas Ross, managing director of Tullibardine, which spends £250,000 disposing of its by-products every year, said "We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental. It takes a cost to us and turns it into something that has social as well as commercial value."

The project is being supported by a grant(拨款) from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth £60m a year.

1.According to the passage, ______will be used to take the place of petrol.

A. whisky B. whisky leftovers

C. butanol D. draff and pot ales

2. How do people deal with whisky leftovers at present?

A. They throw them away.

B. They use them to feed people.

C. They use them to feed bacteria.

D. They use them for crops or cattle.

3.What does the underlined word “utilize” in the fourth paragraph probably mean?

A. make use of. B. get rid of.

C. use up. D. find out.

4.Which of the following categories does this passage belong to?

a. Health b. Science c. Food

d. Nature e. Environment f. Business

A. b,c,e B. b,e,f C. a,b,f D. a,b,c
