Look into hunters' eyes

    Have you ever been face to face with a cat or a sheep? If you have,you probably noticed that cats narrow their eyes to vertical (垂直的) slits (狭缝),while sheep have horizontal pupils (瞳孔).

     Why is the difference?

    Scientists from the Universities of California Berkeley and Durham in Britain may have the answer. Their research, published recently in the journal Science Advances, suggested that pupils' shapes could tell whether an animal is a hunter or gets hunted.

    The researchers took a close look at the eyes of 214 land animals.The challenge was to see if they could find a relationship between an animal's role in the food chain and the pupils' shapes.

    They found a pattern. Species with pupils that are vertical slits are more likely to be small ambush predators (捕猎者) – creatures that lie in wait for their lunch.In contrast,those with horizontal pupils are more likely to be plant-eating prey (猎物) species.

    Evolution chose the arrangement for a good reason.For hunters such as household cats,it appears that vertical pupils not only improve their ability to keep track of moving objects like mice,but also maximize (使最大化) their ability to judge the distances of the animals they hunt.

    However, an interesting discovery from the study is that the slit pupils are mostly linked to hunters that are close to the ground. Therefore, bigger cats who actively hunt down their prey, like tigers and lions, don't have slit pupils.

    On the other hand, for plant-eating prey animals, horizontal pupils give them a wider field of vision.When stretched (伸展) horizontally,the pupils allow for more light to enter from the front, back, and sides. Meanwhile, they also limit the amount of light from the sun above so the animal can see the ground better.“ Once they do find a predator,they need to see where they are running,” said leading researcher Martin Banks,a UC Berkeley professor of optometry (视光学).“They have to see well enough out of the corner of their eye to run quickly and jump over things.”

    But what happens when they bend down to eat? Researchers checked this by watching prey animals in the Oakland Zoo in California, US. They believe that when goats lower their heads to eat,their eyes rotate (旋转) to keep their pupils horizontal.

    So it seems that the eyes are indeed the window to the soul!

    Seven years ago,back in 2010,some reports covered a story that the world's longest railway tunnel was under construction in Switzerland.At that point it had already been under construction for over a decade.It had been voted to be built nearly a quarter of a century ago!The idea to build it could date back to nearly 70 years ago—about as old as some of your grandparents!

Yesterday,it was finally ready!

    It's 35 miles long and runs 7,500 feet beneath the Swiss Alps,a famous mountain range in Switzerland.It even runs under an old tunnel that was there before.It took a total of 17 years to build at a cost of $12 billion.128 million tons of rock were dug.Two million truckloads of earth were removed!

    The tunnel connects northern and southern Europe.The opening of this runnel was such a big deal that the Germany's leader,Chancellor Angela Merkel,France's president,Francois Hollande,and Italy's prime minister,Matteo Renzi,were an there to celebrate,as was Austria's chancellor Christian Kern.

    It's called the Gotthard Base Tunnel.Eventually,325 freight and passenger trains will go through the tunnel,relieving a lot of traffic on the roadways there and making it a more environmentally friendly option.The Gotthard Base Tunnel is a wonder of engineering!Make us want to visit it!

    Walk down any British shopping street and you will find shops with strange names. Why is the opticians (眼镜店) called "Eyediology"? And who decided to name the butchers (肉铺) "Meat you there" ? What's going on?

    Puns are jokes based on words that sound the same. You've probably noticed that many words in English which are spelt in different ways and have different meanings are pronounced in the same way. Think about the name of the restaurant: "plaice" is a kind of fish so our restaurant is "the place" to eat fish. Butchers sell meat – so we'll "meet you there" – and opticians look after our eyes in a scientific way – so eyed – iology (ideology) is a name that fits. Hairdressers shear (cut) your locks (hair) and comb it – say the three words together quickly and you have the name of a famous detective. In shop titles and adverts, puns are used to get our attention.

    Puns are very old. The ancient Egyptians and Romans liked to pun. Shakespeare uses many puns in his plays – King Richard the Third (the son of York) brings "glorious summer" – just think about a word that has the same sound as son.

    Many people enjoy a good pun (pun / fun for all the family!) – others hate them. Puns aren't really designed to make you laugh. Here are some puns that might leave you asking for no more puns please. Have you heard about the bears who voted in the North Poll? Or the cheetah (印度豹) who couldn't be trusted at cards? Or how about the clever little Australian animal that had lots of koalaifications or the camel (骆驼) with no humps (驼峰) that was called Humphrey (and so was free of humps...)

    Puns can be funny but they sometimes make important points. Here's a fashion tip: "skinny genes make skinny jeans": so don't worry if your jeans don't fit. Look at your parents!

    For those who may not be familiar, there is no such thing as a bicycle grants(补助金). As a matter of fact, there are a number of organizations and programs offering bicycle grants to bicyclers all over the world. Now of course, you can't simply receive money, because you want to buy a new mountain bike. Usually, those awarded grants are working on improving the quality of life. People are excited about the bicycle grants. This type of influence and achievement is gaining the attention of various companies that want to help by providing the necessary funding.

Eastman Kodak Company

    Kodak has developed a fund called the “Kodak American Greenways Awards". They are cooperating with the National geographic Society and the Conservation fund. Each year, they present grants as high as $2,500. The “seed” grant award is awarded to organizations that focus on improving blue ways, greenways, natural areas, and trails.

    US Government

    The government has developed their only program for bicycle riders, called" The US Department of transportation's Recreational Trails Program". The government's program is primarily focused on funding trail projects. The benefits of the fund is recreation, which includes bicycling, hiking, in-line skating, snowmobiling, all-terrain(地面)vehicle riding, and so forth. The great addition to the fund is that they distribute the funding to all the states. This means that everybody has the opportunity of receiving bicycle grants.

    Bikes Belong Coalition

    The Bikes Belong Coalition makes putting more people on bicycles their priority. They advocate for a better environment, recreation, sports, and better health, by way of bicycling. At the same time, they provide funding for supporting projects and bicycle facilities. Some of the projects they accept are paved lanes and bike paths. Applications for their grants can be submitted by either a facility class or a supporting class. Also, Bikes Belong Coalition are not quick to award bicycle grants to those who have been awarded in the past 3 years. This is partially due to their limited amount of funding
