Every year, 340 million birds are killed on roads in the US. 335,000 European hedgehogs (刺猬) are killed on roads in the UK. When driving down most highways and sometimes also on roadways in cities, animals are hit by cars or other vehicles (车辆) by accident.

A recent study showed, for the first time, the fast-developing road network is badly influencing on animals in cities in China. Li Zhongqiu and his team from Nanjing University looked at the problem and started the research. First, they chose Nanjing as the study subject. A total of nine roads were chosen for the research, including three national highways, with over 224.27 kilometers long. Then the researchers kept an eye on the roads every two weeks over a year. The team recorded a total of 293 road kill cases. Birds made up nearly half the total. Cats, dogs and blackbirds were the three most commonly killed animals. "This may be due to the large number of homeless cats and dogs in cities," Li said. Also, there are usually a large number of blackbirds in eastern China, and they can be attracted by flies or other insects, leading to further accidents.

Roadkill happens more often in November and January, the team found. This may be due to the fact that some warm-blooded animals have to go out and search for food during these times when food is harder to find. The researchers call on policymakers to develop some traffic and animal protection rules, such as speed limits and traffic controls. And they think to build special roads for animals is a good way. These are four "life passages" for animals used in some countries.

When spring comes, flowers begins to bloom(开花). Signs of new life are everywhere. For students in the US, this means a vacation is on its way. {#blank#}1{#/blank#} So while students from one town are on vacation, their neighbors in the next town might have classes as usual.

Spring vacation is also known as" spring break". During this time, students have one to two weeks off from school.{#blank#}2{#/blank#} Some schools plan the vacation to take place on the same week as Easter(复活节) . Not all schools do this, though. Since Easter is always on a Sunday, students who celebrate the holiday do not need to worry about missing school.

{#blank#}3{#/blank#} Teachers usually don't give homework over the break, so students can spend their days and nights free from school- time stress.

There are lots of ways to spend the time. Some families go on vacation, visit a new state or even a new country. {#blank#}4{#/blank#} Or students may enjoy the break by relaxing at home, reading books and watching movies, or visiting friends' houses.{#blank#}5{#/blank#} On a ten- day trip, for example, students might go on a tour through Spain, France, and Italy. These trips are often expensive, but they give students an unusual chance to see other parts of the world.

When students return to school, they are relaxed and ready to finish the school year.
 

The People's Republic of China was founded on 1st October 1949. Later, from 1st October to 3rd October every year, Chinese people have some days o{#blank#}1{#/blank#}. This year, Lingling and her parents are going to spend the holiday in Shandong Province. They will visit some friends there and will stay there2 u{#blank#}2{#/blank#} the end of the holiday. 

The national day in the US is called Independence Day. It was first celebrated on the fourth of July in 1777. And the American people have celebrated it s {#blank#}3{#/blank#} then. 

The UK doesn't have a national day. People there just celebrate Christmas with a two- day holiday. It's the start of the vacation s{#blank#}4{#/blank#}.
