Hi Cathy,

Greetings from Nepal! I’m sending this from an internet café in a small town north of Kathmandu. The town itself isn’t very interesting, but everything around it    1    (is/are) beautiful — I can see the Himalayas through the café window!

The courses here are great, although maths    2    (is/are) certainly not my strong point. A lot of Nepal’s population lives in the mountainous parts of the country south of the Himalayas, and most of these people    3    (depend/depends) on growing crops and keeping animals. The standard of living in Kathmandu and the other cities    4    (have/has) risen a lot recently, and the number of people likely to move into the cities    5    (is/are) expected to increase. It’s a real problem here. The Himalaya Times, the local English-language newspaper,     6    (has/have) just published a survey showing that most young people would stay in their home villages if jobs were available.

Hope all    7    (is/are) well with you. I’ll send more news when I can.

Nazim

Forests in the northern half of the globe could be growing faster now than they were 200 years ago as 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 (浓度) of carbon dioxide in the     1    .

Geoffrey Parker, a scientist at the Smithsonian Environmental Research Centre in Edgewater, Maryland, said that the increase in 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.

For years scientist have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more     1     than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired, to     2     eye-pain, headache and other problems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists     3     that every modern house has some kind of indoor pollution. People began to     4     the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that     5     the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to     6     harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control     7     for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen     8     its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each     9     different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.
