1 . Portugal’s white storks (鹳) were once a migratory bird (候鸟), known to leave the area each winter to travel to Africa’s warmer climate, but recently they have been staying put.
Surprisingly, though, the storks’ number has actually been on the rise. There are now thought to be more than 14,000 birds in Portugal in winter — a ten-time increase over the last 20 years. Any unusual change of an animal’s natural behavior often has negative influences.
It has been thought that their increase has a close relationship with a growing number of landfill sites (垃圾填埋场) in the area, providing the birds with a supply of fatty and dirty rubbish to eat, including junk food. Was it the junk food that stopped them migrating, or is Europe’s warming climate to criticize? Researchers sought to figure out exactly why their natural behavior had changed in this way. To understand, a team kept an eye on 48 white storks by equipping them with small GPS computers, which recorded their movements five times a day, checking how often they traveled to landfill sites as well as how fast they flew.
The conclusions were shocking. The birds also established more homes next to landfill sites — the team said that 80% of white storks were spending most of their time by the rubbish all year round, according to the results. The storks eat almost anything. “Every time after a truck with rubbish came, they collected what they could,” says Aldina Franco of the University of East Anglia in the UK. The storks have even been known to eat plastic, including old computer parts. “Really what they are trying to get at is rubbish that we throw away... like hamburgers, burnt meat and fish,” said Franco.
This rich and colorful supply of food will soon become hard to find, though, as new laws from European Union (EU) order that waste food be recycled. Open-air landfills will also be replaced by covered equipment, which birds will not be able to eat.
The white storks therefore face an uncertain future. Will they migrate to Africa as they had done for hundreds of years before, or will they stay put? No one knows. “I wonder what the Portuguese storks will do once the landfill sites are all closed, and we are going to continue to watch these storks and see how they will respond to the changes,” said Aldina Franco.

2 . Avoid These Five Gardening Mistakes
Much of gardening is learned by trial and error — that means, from mistakes. We have all been in that situation. Here is a list of five common gardening mistakes with advice on how to avoid them.
Not testing soil
Having the right pH level, a measure of acidity(酸性), for the soil is important for gardening success.
Watering incorrectly
Most garden plants require 2.5 to nearly four centimeters of water weekly. The water could come from rainfall or from your home. Mold and bacterial(霉菌、细菌引起的) diseases, however, could spread if too much water becomes caught between plant parts.
Not composting(堆肥)
A plant that needs “full sun” will likely disappoint if planted in an area without sunshine. The same is true the other way around. And do not put “drought-tolerant(耐旱的)” plants, or plants that can survive long periods without water, in “poorly-draining, wet soil.” Choose the plants that are right for your growing conditions. The result will be a better-looking, healthier garden that requires less care and less work.
Improper mulching(用覆盖物覆盖)
Mulch is material made out of old leaves, wood or compost.
A.Wrong plant, wrong place |
B.Close your eyes to plants or flowers |
C.It can keep water and heat in the soil |
D.The pH level isn’t the same in different parts of the garden |
E.Compost, made of food or plant waste, is a gardener’s best friend |
F.Add five to seven centimeters of water around plants several times a day |
G.Too much water can spread these problems from infected (传染) leaves to healthy ones |
