[填空题]Earthquake
Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself. Other damage results from landslides or major fires which are initiated by the quake.
These are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from upward. The highest scale recorded to date is 8.9. Major damage generally occurs from quakes ranging upward from 6.0.
The actual cause of the quake itself is the breaking of rocks at or below the earth’s surface. This is produced by pressure which scientists believe

[不定项选择题]共用题干 第二篇

Students Learn Better with Touchscreen Desks

Observe the criticisms of nearly any major public education system in the world,and a few of the many
complaints are more or less universal.Technology moves faster than the education system.Teachers must
teach at the pace of the slowest student rather than the fastest. And一particularly in the United States一
school children as a group don't care much for,or excel(擅长)at,mathemnatics. So it's heartening to learn
that a new kind of"classroom of the future"shows promise at easing some of these problems,starting with
that fundamental piece of classroom furniture:the desk.
A UK study involving roughly 400 students,mostly aged 8一10 years,and a new generation of
multis-touch,multi-user,computerized desktop surfaces is showing that over the last three years the technology
has appreciably boosted students'math skills compared with peers learning the same material via the con-
ventional paper-and-pencil method.How?Through collaboration,mostly,as well as by giving teachers better
tools by which to micromanage individual students who need some extra instruction while allowing the rest of
the class to continue moving forward.
Traditional instruction still shows respectable efficacy(效力)at increasing students'fluency in mathe-
matics,essentially through memorization and practice一dull,repetitive practice.But the researchers have con-
cluded that these new touchscreen desks boost both fluency and flexibility一the critical thinking skills that al-
low students to solve complex problems not simply through knowing formulas and devices,but by being able
to figure out what the real problem is and the most effective means of stripping it down and solving it.
One reason for this,the researchers say,is the multi-touch aspect of the technology.Students working in
the next-gen classroom can work together at the same tabletop,each of them contributing and engaging with
the problem as part of a group.Known as SynergyNet,the software uses computer vision systems that see in
the infrared(红外线的)spectrum to distinguish between different touches on different parts of the surface,
allowing students to access and use tools on the screen,move objects and visual aids around on their desk-
tops,and otherwise physically interact with the numbers and information on their screens.By using these
screens collaboratively,the researchers say,the students are to some extent teaching themselves as those with
a stronger grasp on difficult concepts pull other students forward along with them. What has been found after the new tech is employed?
A.Students become less active in learning mathematics.
B.Students show preference to the conventional paper-and-pencil method.
C.Teachers are able to give individualized attention to students in need.
D.The gap between slow learners and fast learners gets more noticeable.
