The brain of an insect isn’t very big. But insects are somehow still able to make lots of important decisions. Bees, ants and roaches(蟑螂) build hives with thousands of workers doing specialized work. The jobs are done without a head or even a plan. How do insects manage this?

To solve the mystery, scientists in Belgium spent months building robotic roaches and then putting them among real roaches. The final goal of the research is to find out how the simple behavior of individuals gives rise to a collective(集体的) decision. The roach is a good starting point for trying to answer the big question because its social system is simple enough for scientists to study.

The first step was to build robots that real roaches would accept as their own. Although the robotic roaches don’t look much like the real thing, they have similarities with them in three key ways: they naturally head toward dark areas, they are influenced by the behavior of other roaches, and even more importantly, they smell like roaches.

The next step was getting the robotic and real roaches to work together on common tasks. In experiments, the robots would collectively head towards a dark place, copying the behavior of natural roaches. That got the researchers wondering: if you program the robotic roaches to go toward the lighted place, will the real roaches follow, going against their natural instincts.(本能) ?

They will – it turned out. Many of the real roaches followed the robots to a lighter shelter. But influence turned out to be a two- way street. On occasion, the real roaches were able to override the programming of the robot roaches and get them to turn into dark hiding places. Being social creatures, both the robotic and natural roaches were paying attention to and following the example set by others.

In theory, it would be possible to create a robot that could influence collective decision-making in humans. To do this, researchers would have to invent a robot that people would accept. Fortunately, the technology isn’t there yet.

69. Why do scientists choose the roaches to study?

 A. Their social system is simple               

B. They are social creatures.

C. They are able to build their hives quite well.   

D. It is easy to create robotic ones.

70. The robotic roaches are accepted by real ones because of all the following EXCEPT that ______ .

A. they smell like real ones          B. they look exactly like real ones

C. what they do are somewhat influenced by other roaches

D. they naturally head toward dark areas

71. What’s the author’s attitude to creating a robot that would influence collective decision-making in humans?

 A. Uninterested           B. Positive       

C. Negative              D. Doubtful

72. Which of the following might be the best title of the passage ?

A. Scientists’ Research                   B. Robotic Roaches

C. Amazing Insects                      D. Insects’ Social System

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窝). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .

   Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!

   If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If  someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.

   Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.

   Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.

1. If you make a beeline for something, you ______ .

   A. are as busy as a bee            B. go quickly and directly towards it

   C. always go to the same place     D. buy something at a certain place

2. The underlined expression “ it is the bee’s knees” _______ .

   A. is not used at all now          B. was first used in the 1820s

   C. reminds us that bees have knees  D. means “it is very good”

3. If you ask your American friend Jack “How old is your wife?” he may say “______.”

   A. It is none of your beeswax      B. You have a bee in your bonnet

   C. It is the bee’s knees            D. You are talking about the birds and bees

4. When you have butterflies in your stomach, you ______ .

   A. are too sick to sit still           B. have ants in your trousers

   C. are nervous about something     D. have a stomachache

5. The passage mainly tells us _______.

   A. some interesting and useful insects  B. some expressions about insects

   C. the way of learning expressions     D. some newly-invented expressions
