Windbreaks are barriers（屏障）formed by trees and other plants．Farmers plant these barriers around their fields，which help prevent the loss of soil，and stop the wind from blowing soil away．They also keep the wind from damaging or destroying crops．Besides，extra trees and plants can be cut down and used or sold for wood．
Windbreaks can be highly valuable for protecting grain crops．For example，in parts of West Africa grain harvests were as much as twenty percent higher in fields protected by windbreaks compared with fields without them．
But here is something interesting about windbreaks．They seem to work best when they allow some wind to pass through the barrier of trees or plants around a field．If not，then the movement of air close to the ground will lift the soil．Then the soil will be blown away．For this reason，a windbreak works best if it contains only 60 to 80 percent of the trees and plants that would be needed to make a solid line．An easy rule to remember is that windbreaks can protect areas up to 10 times the height of the tallest trees in the windbreak．
There should be at least two lines in each windbreak．One line should be large trees．The second line，right next to it，can be shorter trees or other plants with leaves．Locally grown trees and plants are considered the best choices for windbreaks．Trees reduce the damaging effects of wind and rain．Their roots help protect soil from being washed away．And trees can provide animals outdoors with shade from the sun．

Cooks at the Qingfeng Steamed Bun Shop in west Beijing can’t make the pork and scallion baozi (buns) fast enough since Xi Jinping visited for some traditional workers’ food and ate it among the workers.
The Chinese president’s visit late last month went down a treat, while web commentators were enthusiastic in their praise for Xi’s easy populism, after he left the government headquarters in nearby Zhongnanhai and ordered six steamed buns filled with pork and scallions, a bowl of stewed pig liver and a plate of green vegetables.
The bill came to 21 yuan, about €2.50, and he sat and finished it at one of the restaurant tables, just like any other working Joe. While Xi is known as “President Xi” abroad, in China he is known as “Chairman Xi”, in the same way as the country’s late founding father Mao Zedong is known as “chairman Mao”.
The Chinese government is keen for its leaders to have the president title abroad, as it sounds, well, more presidential. But in Qingfeng, it’s all about the chairman.
“Since Chairman Xi came here, the restaurant has had queues like this every day. We didn’t know the chairman was coming beforehand. We only recognized him when he was at the window picking up his food because he also waited in the line,” says a waitress.
Xi is building up a reputation as a more approachable kind of leader, a man of the people – something people in Ireland got a taste of when they saw how he handled a hurley in Croke Park during his visit.
There were rumours last year that Xi even took a taxi to ask the driver what was really going on in Beijing, although that may have been a hoax. While his predecessor Hu Jintao was seen as a theorist, Xi’s public profile is high.

Every morning Grandpa got up early sitting at the table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could.
One day the grandson asked, “Grandpa, I try to read the book just like you, but I don’t understand it, and I forget what I understand as soon as I close the book.
