Reducing class size has traditionally been seen as an important way to improve a student's educational experience.

Many public opinion studies have shown that both teachers and parents favor small class size. Teachers who go on strike are often seeking lower classroom numbers among other better working conditions. Many often believe that smaller classes would permit teachers to give more personal attention to their student. This can theoretically lead to improved academic results for student.

But one recent study suggests there is not much research-based evidence to support this idea. The researchers say the idea of smaller class sizes has been studied and debated for many years. However, they noted a lack of clear research to support class size reductions.

The study notes that one of the main problems with reducing class sizes is that it can have very high costs. Increasing class size is one of the most common ways school systems control education spending. Financial limitations make it very difficult for many schools to reduce the number of students in the classroom.

The teachers' goal was to examine the major research studies already completed on the subject. They especially centered on studies that tried to measure whether the smaller class size resulted in greater success for students.

'The researchers conclude that there is some evidence to suggest that reducing class size may lead to some improvement in a student's rending achievement. But they said "the effect is very small." They found just a 53-percent chance that a randomly selected test score from a student from a small class would be higher than the selected score of a student from a lager class. For mathematics achievement, the result was 49 percent. This led the researchers to conclude that there would be little benefit to math students in a smaller class size.

1.Why do some teachers prefer reducing class size?

A.They believe it may help improve students' academic performance.

B.It'll greatly better their working conditions.

C.They think it will bring much attention to their efforts.

D.It will offer them more time to relax.

2.What is the reason for increasing class size in many schools?

A.Making more profits.

B.Attracting more students to study.

C.Cutting down education expenses.

D.Handling the problem of a lack of teachers.

3.According to the text, reducing class size 　　　　 .

A.has nothing to do with students' scores

B.has a minor effect in some fields

C.has already led to greater academic success

D.isn't practical because parents object to it

4.Which of the following could be the best title for the text?

The rapid growth in skyscrapers worldwide, most of which have large windows, has led to a high demand for window washers. Though the job is well-paid, it is dangerous and accidents are not uncommon. However, if Israel-based start-up Skyline Technologies has its way, the dangerous job may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.

Much like humans, Ozmo, sitting on platforms hanging from the buildings, uses its arms and brushes to clean the dirt on the glass. A 3D map of the building’s surface programmed into its system allows the robot to skillfully deal with any obstacle it is likely to meet, as it moves up and down the buildings. The robot will self-correct and move around every obstacle that it might have met so as not to break a window.

Unlike present window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled (蒸馏的) water to do the job. Yaron Schwarcz, CEO of Skyline Robotics explains, “We are environmentally friendly.”

Ozmo is also expected to be much more efficient than its human counterparts. While it presently takes three cleaners 480 hours each to clean windows of a 40-storey glass building, the robot will be able to do it in 80 hours. However, unlike other robots, Ozmo will not replace human workers, and only make their jobs safer by making them supervisors, who will be controlling the operation from the safety of the ground.

Whether Ozmo, which is still being tested, does as good a job as humans remains to be seen. If things go well, its creators have much bigger ambitions for Ozmo. Schwarcz told Forbes Magazine, “Window cleaning is just the tip of the iceberg. We plan to replace all tasks that are dangerous and dirty.”

1.Why is Ozmo friendly to our environment?

A.It uses less soap than other robots.

B.It depends on solar energy.

C.It makes our ecosystem more balanced.

D.It consumes nothing made from chemicals.

2.What can we infer from the passage?

A.Like cleaning windows, a well-paid job is usually dangerous.

B.Without humans supervising, Ozmo could have performed better.

C.Ozmo can save 400 hours per building compared to a human cleaner.

D.Ozmo can’t be stopped by obstacles with its advanced system.

3.What does the underlined part “the tip of the iceberg” mean?

A.A small part of a big plan.

B.As cool as the iceberg.

C.The most advanced technology.

D.The leading role in the modern world.

4.What is the best title for the text？

A.Robots make a difference.

B.Meet Ozmo, the window cleaning robot.

C.Supervise Ozmo, human safe.

D.Intelligent Ozmo becomes known worldwide.
