In the far north-eastern corner of South Africa, Kruger National Park is the largest
game reserve (野生動植物保護區(qū)) in the country, and the most famous wildlife zone
on the African continent. Stretching out over 7,332 square miles, Kruger is a wonderland
of wildlife. It has 507 species of birds and 147 species of mammals. It also has a fair bit
of history it dates back to 1898 when it was founded as a game reserve in an attempt to
control hunting in the area. It didn't see a tourist until 1927; however, one year later it
became a national park.
It's a good place to see roaring beasts in their own backyards. South Mrica is an
increasingly hot tourist spot, and you may want to visit it this year, before it hosts the
2010 football World Cup. South Africa is also an inexpensive country for tourists.
Anyone seeking to escape the European winter will be surprised to hear that March
is not the best time to go to Kruger.
The six-month period between May and October tends to be the most suitable time
for wildlife - spotting. The weather is not only cooler but also considerably drier. This
means that water sources dry up and animals are forced to approach rivers, creeks, dams
and watering holes in search of liquid refreshment.
If you go to South Africa, you need to pay attention to the threat of malaria (瘧疾).
Kruger is one of the only two South African national parks that have an issue about the
disease, but only during the rainy season ( December to April).
A disadvantage of Kruger is that it sits a long way from South Africa's other well-known
tourist attractions Cape Town, the Garden Route, and the meeting of the Atlantic and Indian
Oceans at Cape Agulhas.

a result of climate change, according to a study of trees in eastern America. The trees appear to have faster growth rates due to longer growing seasons and higher concentrations (濃度) of carbon dioxide in the 1______. Geoffrey Parker, a scientist at the Smithsonian Environmental Research Centre in Edgewater. Maryland, said that the increase ha the rate of growth was unexpected and might be 2______ to the higher temperatures and longer growing seasons documented in the region. The growth may also be influenced by the significant 3______ in atmospheric CO2, he said. "We made a list of reasons these forests could be growing faster and then excluded half of them," Dr Parker said. Their study suggests that northern forests may become increasingly important in 4______ the influence of man-made CO2 on the climate. Dr Parker and his colleagues have 5______ out a detailed record of the trees on a(n) 6______ basis since 1987. They calculated that due to the global warming the forest is producing 7______ tons of wood each year. The scientists 8______ the land with trees at different stages of growth and found that both young and old trees were showing increased growth rate. More than 90 per cent of the tree groups had grown by between two and four times faster than the scientists had 9______ from estimates of the long-term rates of growth. |

We produce 500 billion of plastic bags in a year world-wide and they are thrown
away polluting oceans, killing wild-life and getting dumped in landfills where they take
up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a
solution.
The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate
Institute, has discovered a-way to make plastic bags degrade(降解)in as few as 3months,
a finding that won him first prize at the Canada-Wide Science Fair, a $10,000 prize, a
$20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by
microorganisms(微生物). If those microorganisms could be identified, we could put them
to work eating the plastic much faster than under normal conditions.
With this goal in mind, he ground plastic bags into a powder and concocted(調(diào)制)a
solution of household chemicals, yeast(酵母)and tap water to encourage microbes growth.
Then he added the plastic powder and let the microbes work their magic for 3 months. Finally,
he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead
bacteria as a control. Sure enough, the plastic exposed(暴露)to the live bacteria was 17%
lighter than the control after six weeks.
The inputs are cheap: maintaining the required temperature takes little energy because microbes
produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
"Almost every week I have to do chores and when I open the closet door, I have piles of plastic
bags falling on top of me. One day, I got tired of it and I wanted to know what other people are
doing with these plastic bags. The answer: not much. So I decided to do something myself." said
Daniel Burd.
