“Wolf!”

 Lydia Angiyou's five-year-old nephew Paulussie whispered with alarm as he touched her

arm. At first, she didn't believe him.

     Angiyou, Paulussie, her another newphew Lueassie, also five, and her youngest son Jessie,

seven, were walking to her mother's house one night last February. Animals were often sighted

near lvujvik--a village of 274 Inuit on the shore of Hudson Bay--but rarely on its streets.

     The 41-year-old teacher and mother of five turned around. Looking behind her into the

darkness, at first she thought that Jessie was the wolf. But a meter behind the boy was 350kg

polar bern -no wolf in sight--standing on the icy road. Jessie turned and saw it, too, then ran,

screaming, to his mother.

     Angiyou felt a rush of blood to her brain. "Get as far away as you can!" she shouted to the

boys as she ran towards the bear. She stopped just in front of it, then faced it quiedy. It made a

move to go around her to get to the boys, who must have seemed like the easier meal.

    But Angiyou moved with the bear to maintain her position blocking the children. Finally she

got the animal's attention. In response, it rose on its hind legs to its full 2.5m height. The bear

charged, and knocked her into a seated position. The skin under her nose tore. Falling onto her

back, she screamed for help and kicked at the animal in a bicycling motion. She soon passed out.

     Sirqualuk Ainalik, a fellow teacher, had been at his brother's house nearby when Jessie

dashed inside for help. Grabing a rifle, the 33-year-old ran to the road, firing a warning shot into

the air. He then aimed his gun at the huge bear.

     With two more shots, Ainalik killed the polar bear.

People living more than three thousand meters above sea level find it difficult to raise vegetables all year long. People living in the highlands of Peru and Bolivia, for example, cannot grow vegetables outdoors during the months of May through September. It is very cold in the highlands at that time of year. If traditional farming methods are used, vegetables will not survive.

However, there is another way to grow vegetables throughout the year in cold areas. It is a method of gardening developed by a private agency called World Neighbors. The method uses “hot houses” built below ground. A hot house is a building covered with plastic or glass in which vegetables or flowers are grown. The traditional hot house is built above ground.

The air temperature is cold in the highlands of Peru and Bolivia during the winter. But, the winter sun is hot. So, World Neighbors advises farmers there to build hot houses below ground. The design is simple. The material does not cost much. Here is how World Neighbors says to build it: Dig a hole two and one-half meters wide and six meters long. Make it about two meters deep. Build wall with a door in one end of the hole. Dig steps from the ground down to the door.

Now, build a wall along the top edge of the hole. Make it about one-half meters tall. Earth bricks work fine. Build two shorter walls on the ends. These will be uneven; one side will be as high as the existing wall. The other side will be at ground level. Leave a small opening in each of these sloping walls. This prevents the hot house from becoming too hot. Now, make the roof. Build a wood frame. Cover it with clear plastic. Connect it to the brick walls.

The underground hot house we have described is large enough for two raised vegetable beds. Each is one meter wide and six meters long. Each is seeded and watered just as if it were in a garden above ground.

The dirt walls protect the growing plants from the cold. The clear plastic roof permits the sun’s heat to enter. At night, the roof should be covered with straw. This helps prevent cold air from entering. An under ground hot house this size will provide enough vegetables for one family. Groups needing more vegetables can make it bigger.

66. If you lived in Peru, you _______.

A. should raise the special kinds of vegetables that can endure cold

B. could not plant at all

C. had to work out some new unusual plans

D. would not have many vegetables to eat

67. To our surprise, the “hot houses” invented by World Neighbors are _______.

A. covered with a transparent plastic ceiling

B. built under ground

C. quite small

D. hotter than traditional ones

68. The hot house can be kept warm by using _______.

A. a big oven  B. an electricity heater

C. the heat of the earth’s interior   D. the sun shine

69. The measure to prevent the hot house from becoming too hot is to _______.

A. make the roof sloped B. dig holes on the walls

C. make the wall not vertical D. make the walls shorter than the ground level

70. According to the passage, the method suggested by World Neighbors is _______.

A. new and difficult      B. uneasy to explain

C. at trial step D. simple and practical

    The sun is setting on a summer night. At the entrance to a deep dark cave, a few bats fly out high up into the air. More and more of the small 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.

Sounds 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. Every March or April, Mexican free-tailed bats fly up to 1,000 miles from their winter home in Mexico to this cave, where they raise their young. Soon after they arrive, each mother gives birth to a baby. As many as 500 baby bats crowd into one square foot of space. All those badies create nice warm temperatures to keep them comfortable. If you’ve ever lost sight of your parents on a crowded playground, you may be wondering how mother bats recognize their babies. They use their sense of smell to recognize their own babies when it is time for the babies to nurse.

The cave, a quiet place in winter, filled with life all summer. Bat poop, called guano, soon covers the floor,prviding food for tiny organisms(微生物). And then come the bugs. Kennedy says, “you walk in with your headlight on and the floor of the cave is full of bugs. Insects are flying around, and bectles(甲虫) move slowly up you legs!”

    When the adult bats leave the cave at night of 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. When twenty million bats fly out of one cave opening, they make a column so thick that they show up on radar at the nearby airport. It can take three hours for all of them be to come out.
