I as well as my family are going to New York City this weekend. I had been looking forward to go there for a long time. It is one of the modernist city in the world. There have also a lot of museums where you can learn something you can’t learn it in school. I’d also like to see the Statue of Liberty and the Empire State Building. Unfortunately, the twin towers destroyed on September 11th, 2001 and I would have the chance to see them by myself. Now I am getting ready for the excited trip. I bet it will be a unforgettable experience.

Spend less time outdoors.This is the most effective way for self-protection in such bad weather.With PM2.5 increasing 103mg per cubic meter,residents will risk a 2.29% increase of death,which experts found out in 2012.If you have to get out,avoid riding bicycles.2.
Close your windows.Experts advice residents to avoid opening windows at home.If you have to ,avoid the time when smog is at its densest（浓的）.3.Besides,you can keep plants with broad leaves at home to absorb dust,and use air purifiers（清洁器）.
Smoke less.4.In hazy weather,smoking would be even more harmful.Smokers are advised to keep their distance from cigarettes before the weather gets better.
5.For example ,wear special masks outside to avoid breathing in PM2.5.Then take off your coat after getting indoors and keep it away from your other clean clothes,Don’t forget to wash your face,rinse（漱）your mouth,and clean your nasal cavity（鼻腔）to clean the particulate matters（颗粒物）that fall on you.Last but not least,keep off stimulating（刺激性）foods.

F.Take more fruits and vegetables instead,which are good for lung,spleen（脾）and kidney（肾）.
G.For residents who use air-conditioner,make sure your apartment has enough oxygen indoors.
Pigeons may only have a brain the size of a thimble (顶针), but it appears that pigeons can categorize and name objects in the same way human children learn new words.
A new study from the University of Iowa has shown that the birds are capable of learning to categorize 128 different photographs into 16 basic categories.
Scientists taught three pigeons to sort out different kinds of dogs or types of shoes, for example by using a particular symbol in exchange for a reward. When they were shown black and white pictures of previously unseen dogs or shoes, the birds were able to correctly match these with the corresponding symbols.
The scientists behind the project say this is a similar approach taken by young children when they are first learning words for objects. However, the researchers said it look their birds around 40 days to perfect the task of learning just 16 categories.
Professor Edward Wasserman, who led the work, said: “Our birds’ rate of learning appears to have been quite slow. Would children learn faster than pigeons? Almost certainly. However, our pigeons came to the experiment with no background knowledge at all. Thus, the more relevant comparison group may be newborn babies, who indeed take 6-9 months to learn their first words.”
Writing in the journal Cognition, the researchers said their experiment was a very simple mirror of the way children are taught words — by their parents pointing to pictures and asking them to name the object.
Pigeons are known to be smarter than many birds. Professor Bob McMurray, who also took part in the study, said the results showed that human learning is not as unique as was previously believed.
He said: “Children are facing a huge task of learning thousands of words without a lot of background knowledge to go on. For a long time, people thought that such learning is special to humans. What this research shows is that the ways in which children solve this huge problem may be shared with many species.
