In the botanical garden we can find a(n)____of plants that range form tall trees to small flowers.

A.     species  B. group  C.  amount  D. variety

  A good teacher is many things to many people.In my own experience, the people I respect the most and think about the most are the teachers who demanded(要求)the most discipline(紀律)from their students.

  I miss one teacher in particular that I had in high school.I think she was a good teacher because she was a very strict person.I remember very vividly(清晰地)a sign over her classroom door.It was a simple sign that said,“Laboratory-in this room the first five letters of the word was emphasized(強調), not the last seven.”In other words, I guess, labor(勞動)for her was more important than oratory, which means making speeches.

  She prepared her work very care fully and demanded us to do the same.We got lots of homework from her.Once she had broken her arm, and everybody in the class thought that maybe the home work load would be reduced, but it con tinued just the same.She checked our work by stamping her name at the bot tom of the papers to show that she had read them.

  I think sometimes teachers who de mand the most are liked the least.But as time goes by, this discipline really seems to benefit(有益于)the students.

What if you arrived home to find a delicious hot meal waiting for you,prepared by your very own kitchen robot? It might sound like science fiction,but professors at the university of Tokyo have taken the first steps toward making that scenario a reality.The team recently introduced a humanoid kitchen robot that can pour tea and other drinks into cups and serve them to guests.When teatime is over,the robot can also wash the dishes and put them away.

In California,another interesting kitchen robot has been developed.Called the Ready-bot,it can pick up objects and either store them in cabinets or put them in the trash.It also carries a separate floor-cleaning robot that can operate by itself.Unlike the Japanese robot,Readybot is not humanoid.Instead,it looks more like a large box with arms and wheels.[來源:Z|xx|k.Com]

Readybot was created by engineers and designers who established a club called the Readybot Challenge.They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks.Readybot is just the first step in their plan to create a robot that can tackle jobs not only in kitchens but in other rooms of homes and in offices as well.

Clearly there are technological hurdles to overcome before robots can cook a complete dinner,and there are also many safety concerns.Not everyone(especially parents)would be comfortable with the idea of robots in their house,manipulating hot pans and sharp knives.The European Commission recently funded a project to study these concerns.

56.What does the writer imply about the Japanese robot?
