education, according to new research.
Dr. Helen Lees, from Stirling University"s school of education, says that "enforced (强制的) silence
" is seen as a punishment and often acts to suppress children"s natural ability. But she says that teaching
children about the benefits of "enforced silence",-deliberate stillness that gives them the opportunity to
focus and reflect in a stress-free environment--- can have a significant effect on pupils" concentration and
behavior.
It is the latest in a string of researches to establish a link between the classroom environment and
pupils" academic ability.
A study almost a decade ago in London found that children"s exam results were cut by as much as a
third if they were taught in noisy classrooms. Teaching unions have also called for a limit of 26℃ to be
put on classroom temperatures because teachers and pupils struggle to work in hot conditions, and some
educationalists claim that too much clutter (杂乱的东西) on classroom walls can prevent children from
concentrating.
Dr. Lees said, "When we take some research on school settings and put it all together, what we see is
that education without silence does not make much sense. In areas of better learning outcomes, better
self- confidence and well-being measures, enforced silence in a person"s life and an individual"s education
is shown throughout the relevant research to be a benefit."
Dozens of schools across Britain have already introduced periods of "reflective silence" into the
timetable.
Kevin Hogston, head of Sheringdale Primary, south London, has just introduced a minute"s silence at
the start of twice-weekly meetings in which children are taught breathing techniques and encouraged to
reflect. The school plans to introduce it into classrooms every day.
B. does not make much sense in class
C. can improve pupils" confidence
D. makes pupils more creative
B. improve
C. apply
D. reveal
B. Silence makes a great difference to pupils.
C. Clutter on the walls can help students concentrate.
D. Most schools are not satisfactory in terms of classroom temperatures.
B. Achieving silence is beneficial for people
C. Using enforced silence is effective punishment
D. Keeping quiet in class improves academic performance
the southernmost coastal city to the northernmost coastal city would measure about 225 miles. If you
followed the coastline between these points, you would travel more than ten times as far. This irregularity
is the result of what is called a drowned coastline. The term comes from the glacial (冰川的)activity of
the Ice Age. At that time, the whole area that is now Maine was part of a mountain range that towered
above the sea. As the glacier descended, however, it applied enormous force on those mountains, and
they sank into the sea.
As the mountains sank, ocean water charged over the lowest parts of the remaining land. And the
highest parts of the former mountain range, nearest the shore, remained as islands. Marine fossils found
here are 225 feet above sea level indicating the level of the shoreline prior to the glacier.
The 2,500-mile-long rocky and jagged coastline of Maine keeps watch over nearly 2,000 islands.
Many of these islands are tiny and uninhabited, but many are home to blooming communities. Mt. Desert
Island is one of the largest, most beautiful of the Maine coast islands left behind by the glacier. Measuring
16 miles by 12 miles, Mt. Desert was very nearly formed as two distinct islands. It is split almost in half
by Somes Sound, a very deep and very narrow stretch of water seven miles long.
For years, Mt. Desert Island, particularly its major settlement, Bar Harbor, has afforded summer
homes for the wealthy. Recently, though, Bar Harbor has become a new arts community as well. But the
best part of the island is the unspoiled forest land known as Acadia National Park. Since the island sits
on the border between two different geographical zones, the park supports the plants and animals of both
zones. It also lies in a major bird migration lane and is a resting spot for many birds.
The establishment of Acadia National park in 1916 means that this natural monument will be
preserved and that it will be available to all people, not just the wealthy. Visitors to Acadia may receive
nature instruction from the park naturalists as well as enjoy camping, hiking, cycling, and boating. Or
they may choose to spend time at the museum learning about the Stone Age inhabitants of the island.
