The sun is setting on a summer night． At the entrance to a deep, dark cave, a few bats fly out and begin swirling high up into the air．More and more of the small, furry creatures appear．Within a few minutes, a whole river of bats is pouring out of the cave, and they keep coming, millions and millions of them．

       Sound like a scary horror movie? Believe it or not, this scene takes place every night, all summer long, at Bracken Cave in Texas, where 20 million bats fly outside to feed on insects．"It is magical," says Jim Kennedy of Bat Conservation International in Austin Texas．"It is one of the most majestic（壮丽的）  animal movements on the planet．"

       Every March or April, Mexican Free-tailed bats migrate up to 1,000 miles （1609 kilometers） from their winter home in Mexico to this cave, where they raise their young．Soon after they arrive, each mother gives birth to one pup．As many as 500 baby bats live crammed into one square foot （30．48 cubic centimeters）of space, and all those bodies create nice warm temperatures to keep them cozy and comfortable．If you've ever lost sight of your parents on a crowded playground, you may be wondering how mother bats recognize their children．They use their sense of smell to tell which pup is theirs when it is．time for the babies to nurse．

       The cave, a quiet place in winter, is full with life all summer-and not just with bat residents．Bat waste soon covers the floor, providing food for tiny organisms（生物体） like bacteria and fungi（真菌类）．And then there are the bugs．

       When the adult bats leave the cave at night to feed, they are helping humans．They eat tons of insects in a single night, including many pests that eat farmer's crops． And they get rid of mosquitoes, too．

Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.

Unless otherwise posted, the maximum (最大限度的) speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is not allowed to take automobile radar detectors (汽车雷达检测器) into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles’ headlights on during the day and some have banned (禁止) driving while using a hand-held cell phone. Motorcycles cannot share a lane (车道), and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.

Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas. 

Highway 401, from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

Who owns the sea? The ships of all countries sail in the open seas. Not long ago, all countries could fish and hunt in the oceans as they pleased. But now, the countries using the sea must work together to protect the animal life in the seas.
In 1870, there were millions of valuable fur seals in the Berling Sea. Ships came from all over the world to kill them.
Man wanted the animals’ fur and their oil from their bodies. By 1930, only about 130,000 seals were left there in the seas and the oceans. Even the hunters themselves knew that something had to be done to protect them, otherwise the seals would die out or disappear from the earth forever.
Four countries owned the land near the seals’ northern home. In 1911, these countries began plans to control seal—hunting. The governments of these four countries, Japan, Russia, Canada and the United States, where the animals rested and gave birth to their young, formulated a policy that only male seals that didn’t have mates were to be divided among the four governments.
Today, large herds of seals swim in the Berling sea again. By working together, the four countries mentioned above have saved the seals in the seas they share.
