that has tried the patience and intelligence of scientists for decades.
Scientists use just seven basic units to define all the other quantities we use-quantities such as speed or
electric power. All of those basic units except the kilogram are themselves defined according to natural
properties (属性) that are beyond human control.
For example, the standard second (time) is defined as a specific number of vibration (振动) of a type of
radiation sent out by atoms of a special metal. The standard metre (length), in turn, is defined as the length of
the path light travels under certain conditions.
Not so the kilogram. This orphan of the basic unit family is simply the mass of a small platinum-iridium
alloy cylinder (铂一铱合金筒) locked away in a container maintained by the International Bureau of Weights
& Measures in Sevres, France, near Paris. Official bodies around the world have copies of the cylinder.
Embarrassingly, the last time the copies were brought to Sevres for a checkup in the 1980s, officials found
that some copies had gained about 20 parts per billion in weight compared to the master cylinder since the
previous checkup in the 1940s. This implies that the master cylinder itself may be an inconstant standard.
Several efforts in several different countries are under way to redefine the kilogram according to basic
physical quantities such as counting the actual number of atoms of a specific substance in a kilogram or the
electromagnetic (电磁的) force that balances a kilogram mass against gravity. A project of the latter type at the
laboratories in Gaithersburg, Md., hopes eventually to define mass by means of electrical units.
So far, none of these redefinition projects has borne fruit. They require the very accuracy of measurement
and control of experimental conditions. The slightest influence-even a tiny change in weather-can ruin results.
You"ve got to hand it to scientists who are willing to devote many years to such painstaking-but extremely
important-research.
B. not universally accepted in the world
C. not defined according to natural properties
D. defined in the same way as other basic units
B. such kind of checks had been carried out regularly
C. the changes in weight challenged the definition of the kilogram
D. the consequences of such changes were great in research
B. has been accepted as the only possible redefinition project
C. is not as complicated as people understand
D. has been considered by some scientists as a better approach
B. Some scientists are trying to redefine the kilogram according to basic physical quantities.
C. The redefining of the standard kilogram is quite complicated and can be affected by a number of factors.
D. A number of experiments are being carried out to redefine the kilogram.

recently claim that children who have low levels of self-control, which is the earliest demands that society
places on children, at the age of three are more likely to have health and money problems and a criminal
record by the age of 32, regardless of background and IQ. That is to say, willpower as a child really does
influence your chances of a healthy and wealthy adulthood.
They found that children with low self-control were more likely to have health problems in later life
including high blood pressure, being overweight, breathing problems and sexually transmitted infections.
They were also more addicted to substances such as tobacco, alcohol and drugs, more likely to be single
parents, have difficulty managing money and have criminal records.
Researchers from Britain, the US and New Zealand analyzed data from two large studies in which
children completed a range of physical tests and interviews to assess genetic and environmental factors
that can shape their lives.
The participants" self-control was assessed by teachers, parents, observers and the children themselves
and included things like having low frustration tolerance, lacking persistence in reaching goals, being over-
active and acting before thinking.
Researchers then found that when the participants reached their early 30s, this impulsivity and relative
inability to think about the long-term gave them more problems with finances, including savings, owning a
home and credit card debt.
The findings were published in the Proceedings of the National Academy of Sciences journal.
1. What are the findings of a recent research according to the passage?
____________________________________________________________________________________
2. The phrase "more addicted to" (Line 3, Para. 2) probably means "____________".
3. Besides poor anti-frustration ability, over-activeness and fore-acting, children with low self-control may
also suffer ____________.
4. What may primarily cause the financial problems of the children with low self-control in their later years?

applied to traditional education, online education, or directly in a career related role. Many teachers find it such
a valuable skill that they give their students a critical thinking question every day. Developing this ability can
mean the difference between "just passing a course" and "understanding the material well enough" so that what
students learn from it will follow them throughout their life.
Some characteristics of a critical thinker that teachers should encourage are:
-asking questions as a reaction to something read or discussed;
-determining the "deeper meaning" of a particular passage or topic;
-providing input and opinions to topics as a direct result of analysis and research;
-reasoning in an effort to develop an argument of your own opinion.
It is important for a student to understand more than definition (定义). One way to truly understand an idea
is to have hands-on practice, and to apply concepts learned in a textbook. Such "mini-examples" will interest a
student and improve their understanding of a topic. This is how lifelong skills can be developed.
Teachers that use critical thinking practices in the classroom can "go above and beyond" by asking questions
that promote a greater comprehension of the material. Instructors should be able to challenge students and
create an environment where they are analysing material and gaining a better understanding. This will make the
classroom move in a direction for learning. It can also help students to stay interested in the course material, as
they always have a new concept to consider.
At the same time, students benefit greatly from developing critical thinking skills. When learned early on,
these skills can be used throughout their college education. Students can understand how to consider a topic,
analyse it, and discuss it from different points of view. These are skills that will benefit them when they are
part of the workforce as well.
B. a method to expand people"s knowledge
C. a way to increase people"s ability to understand
D. a process to make people more critical of others
B. the difference
C. the course
D. the material
B. be able to develop their own opinions
C. predict the deeper meaning of a topic
D. do more analysis and research
B. give students hands-on practice
C. help to keep students interested
D. help students develop concepts
B. Parents.
C. Examiners.
D. Headmasters.

| Texico High School is renewing its professional arts program. For years, one teacher taught the professional arts and was in charge of the Future Farmers of America and Leadership programs. This year, community and school leaders decided to give the professional arts program more attention. The school decided to bring back the program after a survey of the students. The students wanted professional arts classes. To lead the program, the school invited Terry Whitener. Whitener taught leadership and professional arts in Anthony, Texas. "It is difficult to do both well," he said. Whitener took carpentry (木工活) classes while he attended Texico High School. "There were a lot more activities back in the 1980s than when I came here this year," he said. The school has bought new equipment for the carpentry workshop for Whitener"s classes. Whitener said the classes were to give the students a leg up when they left high school "Not all students are going to college," he said. "Even if they do, this program gives them helpful skills." Whitener said he wanted to teach students carpentry classes from a career (生涯) standpoint (立场). "Measure twice, cut once. I tell them no boss is going to want to pay them to do a job twice, when they could do it right the first time," he said. "Traditionally, all the guys were going to be farmers. That"s not true anymore. More kids will use these skills in a career instead of on their own field." "This is something I"m going to do after high school," said Zayne Meeks, one of Whitener"s students. "It gives people better opportunities to get better experience and then a better job." Another student, Lucas Waltners, said he was unsure of what he wanted to do after high school, but that the skills learned in Whitener"s class would be helpful either way. "This is something I"ll know how to do if I ever need to do it," he said. | |
