Scientist Without Laboratories
When you hear the word “scitentist”, what do you think of? Many people think scientist are people in clean white coats who work in labs. And some scientists do work in labs. But there are   26  scientist who work in woods and jungles. These scientists are called “animal behavior (行为) scientists”, and they study animals as they live in nature.
Why don’t these scientists catch animals and study them in zoos? The   27  is in the word “behavior”. Animals behavior scientists want to learn   28  animal behave in their wild homes. When animals live in cages (笼子) or in zoos, they do not act the same as they do when they are   29 . They may fight   30  each other, or they may not eat, or they may not raise (抚养) their babies as they usually would. To see real animal behavior, scitentists must go where the animals   31 .
So animal behavior scientists go into the jungles, the woods or the desert. There , their most important   32  are their eyes and ears. They watch and listen to the animals very   33 . They write down everything that happened in notebook.   34
they live near the animals, the scientists are careful not to frighten them. If the scientists are luncky, the animals will   35  no attention to them. Then the scientists can see how the animals really live.
The behavior scientists hope what they’ve learned about animal behavoir can provide clues (提供线索) to help people learn to live together more happily.

Robots have come a long way since 15th century. We’ve got robots to build cars, carry heavy things, work in dangerous places and explore planets. But things haven’t stopped there.
In 1986, Honda made a robot called ASIMO. And now, it has been developed greatly. Standing at 130cm and weighing 54kg. ASIMO is very much like a small astronaut wearing a bag on the back. And he can walk, flight, climb and run fast. Isn’t it wonderful?
The world’s first robot teacher is Saya. With her human-like face, she can show expressions like happiness, surprise, sadness, dislike, fear and she can even smile or show anger at students, which look much like a real teacher’s. To do this, her rubber skin is pulled from the back with motors inside. And her eyes and mouth have wires(电线) too. She can also say some simple words like “hello” or “thank you”.
In the UK, the development of robots is exciting. The mini-robots will send food, clean floors, collect and throw away waste. These robots can open doors by themselves and stop if anything or anyone is in the way.
These mini-robots are very useful for controlling infection(传染). Usually clean and dirty work is done by the same person, but here, you’ll have robots that do”dirty work”, like collecting dirty sheets, or taking away hospital waste; and you’ll have robots that do”clean work”, like bringing meals or clean sheets to patients. The robots have separate work so there’s no way for infection, which is great. But of course, robots would not take the piece of humans, but would free up more time for nurses to be with patients.
But if this is what it’s like in 2011, what’s it going to be like to 2021?
小题1:In the following, which is ASIMO’s behavior?

A．Smiling at people, saying “hello”.

B．Sending food or opening doors by himself

C．Fighting, climbing or running fast

D．Collecting waste for patients

小题2:What makes Saya look real?

A．Her face and rich expressions	B．Her clothes and shoes
C．Her walking and running speed	D．Her rich knowledge

小题3:Which of the following is true according to the passage?

A．Robots have come a long way since 1986.

B．The first robot teacher was made by Honda.

C．Saya looks like a small astronaut.

D．If anyone or anything is in the way, mini-robots will stop.

小题4:The main idea of Paragraph 5 is that _______.

A．nurses would have more free time with patients

B．robots would not take the place of humans

C．dirty and clean work is always done by the same person

D．mini-robots are useful for controlling infection

We have always been warned of the dangers of forest fires. They cause _____ 85 _____ to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be _____86_____ for a forest? People start some of the fires with a special reason to actually do good to the eco-system.
In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can _____87_____ some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
Some trees even need fires to grow. These trees hold their seeds (种子) inside. Heat from a fire allows the coat of the seeds to open up. Then the seeds fall to the ground and have the _____88____ to grow/
Scientist, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or _____89_____ a after forest fires, they can go hungry _____90_____ their food has been damaged in the fire. Small, controlled fires mean than animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This _____91_____ makes an eco-system.
So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

A．take the place of

B． get ready for

C． be bad for
