Bats are the only mammals(哺乳動物) which can fly properly. Other flying mammals have wings of thin skin which cover their sides between their front and back legs. They can only fly from tree to tree, but they cannot change direction when they want to.

All bats fly at night and most of them hunt for flying insects(昆蟲), such as bees. The common bat finds its food by making a constant noise that the human ear cannot hear. The bat listens for echoes(回聲) of the noise as it bounces(反射) off the insects showing the bat their position.

The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.

1. Some flying mammals are not real flyers because _____.

 A. they do not have wings                     B. their wings are too thin

C. they have skin between their legs             D. they cannot turn around in the air

2. When common bats hunt for food they _____.

   A. use echoes to kill the insects           B. make a noise to draw insects to them

C. produce a sound and listen to the echoes     D. listen noise made by the insects

3. Unlike other bats, the Fruit bat _____.

   A. can see very well                   B. eats fruit and fish 

C. has very long wings                    D. has excellent hearings

4.The word "it" in the second paragraph refers to _____.

   A. the bat           B. the echo      C. the noise       D. the insect

My son and I were trying to sell the house we had repaired but in the barn(谷倉)there were bats(蝙蝠)and they would not leave. The barn was their home. They told us so in their own way. They hung there in the barn and seemed determined to stay for the season. Don’t worry about it, Dad, " Patrick said. They keep down the mosquitoes(蚊子).”
Unfortunately they also kept the buyers away. when we had asked a person to sell the house for us he had refused to show it because of the bats. Bats are popular, “Patrick comforted me. They’re ecological(生態學的).”Isn’t there a machine you can buy that produces high frequency sounds to keep bats away?” “I don’t know,” said Patrick. But I like bats, and whoever buys this house will probably like them too. “Probably?” I hated that word. “How many bats are there ,anyway?” “I counted about 90 last night,” said Patrick. “They were dropping out from under the edge of the roof.” “You mean there are more — outside?” “They’re everywhere, Dad. But look at it this way. When the cold weather comes, they’ll be off to Mexico. Maybe in the spring we can keep them out. Don’t worry about it,” he said for the hundredth time. “It’s not a problem.”
The bat expert I called was even more active than Patrick. I think you’ve got a large number there,” he said in wonder, I’ve been trying to attract bats to our house for 25 years. A single bat eats up his weight in mosquitoes and black flies three times every night. You’re a very lucky man.” I offered to share my luck with him. He could take them away. Bats have a remarkable homing instinct(本能),”he said, “They’d fly straight back even if I transported them 100 miles. Once they have settled, you can’t stop them from coming back.” I was silent.
Finally we managed to rent “(出租)the house to a young family, who were also interested in buying it. What about the bats?” I said to Patrick.
“Oh, they love the bats,” he said. “No mosquitoes. No black flies. It’s one of the things that attracted them.”
“Do you think they will really buy the blouse?”
“Probably.”
“Probably? Well, if they do ,I suppose I’ll have to admit that I was wrong.”
“You mean you’re going to eat your words?”
“Yes, I am.”
36.  What was the problem the author had with his house?

A.?He should buy a high frequency machine.
B.?He should move them one hundred miles away.
C.?He should reduce the number of mosquitoes.
D.?He should close the barn in the spring.

B.?He found out that it would be impossible to remove the bats.
C.?He learned that he would be able to share his luck with the expert.

At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.
There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.
During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down.
Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract(緊縮)several muscles in your arm, which are connected to your fingers by tendons(腱);as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons(爪)close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.
【小題1】Bats hang upside down because________.

A.they haven’t developed a pair of strong clawsB.they can’t start to fly from the ground directly
C.they have no hind legs to support their bodyD.they can’t find quiet places to stay during the day
【小題2】The third paragraph tells us that bats’ hanging upside down_______.
A.is to save their energy for night movementB.is a way to fight against flying animals
C.is a great way to hide from dangerD.is a skill to compete for the flying places
【小題3】Why can bats hang upside down easily?
A.Because their upper body is light.
B.Because they have strong muscles.
C.Because their talons are linked to muscles tightly.
D.Because their tendons are linked to their upper body.
【小題4】 What is the passage mainly about?
A.The living habits of bats.B.How and why bats hang upside down.
C.The importance of bats’ hanging upside down.D.How bats use their energy at night.
