The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit instead of insects. Like all bats, flying foxes hang themselves by their toes when at rest, and travel in great crowds when out flying. A group will live in one spot for years. Sometimes several hundred of them occupy a single tree. As they return to the tree toward sunrise.

Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her breast wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls down to the ground and squeaks for help. Then the older ones try to pick it up. If they fail to do so, it will die. Often hundreds of dead baby bats can be found lying on the ground at the foot of a tree.

1.The passage tells us that there is no difference between the flying fox and the ordinary bat in ________.

A. their size　　 B. their appearance

C. the kind of food they eat　　 D. the way they rest

2.At daybreak every day flying foxes begin to ________.

A. fly out toward the sun　　 B. come back to their home

C. look for a new resting place　　 D. go out and look for food

3.How do flying foxes care for their young?

A. They only care for their own babies.

B. They share the feeding of their young.

C. They help when a baby bat is in danger.

D. They often leave home and forget their young.

Sydney’s Royal Botanic Gardens are to start a war on gray-headed flying foxes. These super bats have invaded one of Australia’s most famous public spaces. Officials have said the animals are destroying trees and have to move on.

These unwanted guests at Sydney’s Royal Botanic Gardens look like tiny foxes with wings. Officials have estimated there are about 11,000 of them living in the harbor-side park. After inspecting damage to dozens of trees they now believe there are twice as many as previously thought. Branches have been breaking under the weight of these furry invaders and their droppings have been poisoning plants.

Help may well be at hand, however, in the shape of the ordinary garbage bin. The gardens’ director Dr. Tim Entwistle hopes the unpleasant sounds of crashing bin lids will agitate the flying foxes and force them to move on. “The way to disturb them is to use noises, so we’ve used the loud noises made by rubbish bins in the past. You can also use speakers as long as you move the noise around, and what we’ll do is to have a series of noises, at the beginning and end of the day. What we’ve found in the past is that the flying foxes leave the gardens and go somewhere else,” said Tim.

The gray-headed flying fox is Australia’s largest bat. It flies around at night using its eyes and a powerful sense of smell to search for fruit and flowers. Officials at the Royal Botanic Gardens in Sydney have said they’re optimistic the unwelcome colony can be uprooted. If and when the bats do move to other parts of the city they will of course then become someone else’s problem.

1.Why do people want to get rid of the flying foxes?

A. Because the gardens are important public places.

B. Because they are polluting the city.

C. Because many garbage bins have been damaged by them.

D. Because they’re threatening the survival of trees and other plants.

2.What are people doing to get rid of the flying foxes?

A. Shooting them.　　 B. Making loud noises.

C. Shaking the trees hard.　　 D. Cutting some trees down.

3.Which of the following can replace the underlined “agitate” in Paragraph 3?

A. excite　　 B. kill

C. disturb　　 D. discourage

4.What does the writer imply from the last paragraph?

A. The bats will still stay in the gardens.

B. Some other areas will have to deal with the bats.

C. The grey-headed flying fox often eats trees.

D. The damage caused by the bats is serious.

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（紧缩）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.

1.Bats hang upside down because________．

A. they haven’t developed a pair of strong claws   B. they can’t start to fly from the ground directly

C. they have no hind legs to support their body    D. they can’t find quiet places to stay during the day

2.The third paragraph tells us that bats’ hanging upside down_______.

A. is to save their energy for night movement      B. is a way to fight against flying animals

C. is a great way to hide from danger             D. is a skill to compete for the flying places

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.

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.

Quality questions are vital for curiosity; Google, is great at finding answers but doesn’t motivate the formation of questions. 3. An excellent book for understanding the art of questioning is A More Beautiful Question by Warren Berger.

4. Curiosity is influential in groups working toward a real-world common goal, helping to inspire questions and new ideas.
