Women are meant to be the experts at shopping, but new research reveals the whole experience leaves them stressed. The surprise findings show that not all women get comfort from shopping. In fact, in a supermarket environment, one third of females feel it a burden when they do the weekly shop despite being organized and armed with shopping lists, The reason why women are more nervous in the supermarket is largely that they are rushing round trying to conduct the shopping as quickly as possible. Doing the food shop will be one item on a massive list of jobs，and something which simply has to be done at speed. Women even admitted to having an argument with another shopper in the supermarket－either because of trolley rage, fighting over the same item or queue jumping. They can't stand feeling rushed when the cashier scans items too quickly so they struggle to get everything into the right bags.
In contrast, three quarters of men quite enjoy their food shopping experience and are happy to push their way around the aisles searching out products. Men are less forgetful about what they want to buy, are less likely to feel rushed by the cashiers and are more methodical at the checkouts. Men seem to adopt a much more laid back and methodical approach, taking their time looking for bargains and make sure they're getting the most for their money.
But the poll suggests women are the savvier shoppers—as they are less baffled by all the different brands in the shop and are more likely to ask for help if needed.

Twothirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to store water and provide power.In the US，there are more than 85,000 dams，disrupting large and small rivers，and in most cases transforming natural flow.The most famous of these，the Hoover Dam，constructed in the 1930s，is mainly responsible for the fact that the Colorado River no longer reaches the ocean.
Dams，besides all their attractive benefits，also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land，houses and culturally important sites.
Environmentally，the new reservoir can be a paradise for wildlife，especially birds；however，it can cause greenhouse gas emissions and poison the water.Also，the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with，resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows，for example，may find a few hours later that those sites are high and dry.
Downstream(在下游方向)of a dam，the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders，which may cause conflict over precious water.Disputes have been continuing between India and Pakistan，and Turkey，Syria and Iraq，for example.
Dams don't just block the flow of water.They also prevent fish migrations，and dams are a barrier to sediment(沉淀物)flows.Instead of rushing downriver，sediments get backed up against the dam wall，which causes the reservoir level to increase over time.However，sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced，with soils lost during seasonal rains not being replaced.
Perhaps the biggest problem can be seen in deltas，which are sinking into the oceans.Groundwater is being extracted to feed the city，causing the city to sink，and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria.

Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.It also helps keep the soil from getting dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds，from growing.
Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.
It is easy to find organic mulch materials.Cutup leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.
The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil. As a result，mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.
