A major source of teen stress is school exams,and test anxiety is not uncommon.When
you recognize your teen is under stress,how can parents help your teen stay calm before
an exam?
Be involved.Parents need to be involved in their teen"s work.__1__What they look for is
your presence-to talk,to cry,or simply to sit with them quietly.Communicate openly with your
teen.Encourage your teen to express his worries and fears,but don"t let them focus on those
fears.

reading and writing paper.No notebooks,no textbooks,no test paper.Nor are there any pencils
or pens,which always seem to run out of ink at the critical moment.A"paperless classroom"is
what more and more schools are trying to achieve.
Students don"t do any handwriting in this class.Instead,they use palm size,or
specially-designed computers.The teacher downloads texts from Internet libraries and sends
them to every student"s personal computer.
Having computers also means that students can use the Web.They can look up information
on any subject they"re studying from maths to social science.
High school teacher Judy Herrell in Florida,US,described how her class used the Web to
learn about the war in Afganistan(阿富汗) over one year ago.
"We could touch every side of the country through different sites from the forest to refugee
camps(难民营),"she said."Using a book that"s three or four years old is impossible."
And exams can go online too.At a high school in Tennessee,US,students take tests on
their own computers.The teacher records the grades on the network for everyone to see and
then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper.High school
teacher Stephanie Sorrell in Kentucky US said she used to give about 900 pieces of paper
each week to each student.
"Think about the money and trees we could save with the computers,"she said.But,with
all this technology,there"s always the risk that the machines will break_down.So, in case of
a power failure or technical problems, paper textbooks are still widely available(可用的) for
these hitech students.
the critical moment" mean?
B．Pens get lost easily,so you may not find them at the critical moment.
C．Pens may have little or no ink at the critical moment.
D．Pens use ink,while pencils don"t.
B．Computers.
C．Information.
D．Texts.
B．the Web taught them a lot
C．the Web is a good tool for information
D．the Web，better than the textbooks，can give the latest and comprehensive(全面的) information
B．teachers
C．trees
D．computers
B．Stop working.
C．Fall down.
D．Lose control.
building can house a vertical farm.Since the garden is built upwards,rather than outwards,it
requires much less space than a conventional(传统的) farm.
The world is quickly running out of room for conventional farming.Vertical farms could be
a key to this situation.An 18story vertical farm could feed as many as 50,000 people,all in an
area which is the size of the average city block.Vertical farms in the city could cut down on
transportation costs as well.Think about the amount of fuel it takes to transport food from
farmland to city.The resources saved would be surprising. Besides saving travel time,food
would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides in agriculture today.But the vertical
farm would be a greenhouse type environment, avoiding the need for a large number of
pesticides.Vertical farms can be built in a contained space,therefore they are an excellent
solution for living well in an environment far different from our own.Hydroponics(水耕法)
could be a big part of vertical gardening.This would reduce the amount of soil needed to grow
food.Of course,not all food does well with this type of planting,but there are many crops
that actually seem to do better.
In some climates,a lack of sunlight creates a short growing season. The solar power option
may not work as well here.The addition of grow lights would make it possible to grow crops
in vertical gardens in these areas.In other words,we could grow crops in areas where we never
could before.
Vertical farms may just be a concept for now,but they are a concept that will solve many
of our problems in the future.
B．is only an environmental friendly farm
C．is planted on levels upwards
D．is dependent on solar power
B．the future of a vertical farm
C．the cost of a vertical farm
D．the benefit of a vertical farm
B．reduce the harmful effect of pesticides
C．depend far less on sunlight
D．greatly increase the use of soil
B．need less room than conventional farms
C．only use hydroponics to grow food
D．may increase the transportation costs
B．Vertical farms and green skyscrapers
C．Ways to deal with future problems
D．Advantages of vertical farms
on February 23. It was the third shark attack along the coast of Australia"s largest city in a month.
The 15yearold boy and his father were in the water off Avalon, on Sydney"s northern beaches,
around dawn when he was attacked. The city"s beaches are packed with locals and tourists during the
summer months.
"The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water, "police
said. "Fortunately, the shark swam away and the boy was helped to the shore by his father. "
Lifesaving Club spokesman Nick Miller said, "It got him around the top of his left leg and the father
came and dragged him out of water. "He said the boy was bleeding heavily when he was brought to the
shore. "There was a lot of pain, as you can imagine. "The teenager was airlifted to hospital for treatment
for leg injuries.
Police said the bites "cut through to the bone", but the boy did not appear to have sustained any
fractures (骨折). He was in a stable condition now.
Several beaches were closed after the attack. Water police and lifeguards were searching for the
shark, while police hoped to identify its species by the shape of the bite marks. But they said it was too
early to say what type of shark attacked the boy. "I don"t even know if he saw it, "Miller said.
Many shark species live in the waters off Sydney"s beaches, but attacks on humans are still relatively
rare. However, there were two attacks on successive days earlier this month, one on a navy diver in
Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city"s
worldfamous Bondi beach.
Fishermen say shark numbers are on the rise. There is a ban on commercial fishing in the harbor,
which has increased fish stocks. Marine experts also claim environmental protection has created a
cleaner environment, attracting sharks closer to the shore as they chase fish. Many shark species,
including the Great White-the maneaters made famous in Steven Spielberg"s Jaws-are protected in
Australian waters.
B. sharks attacked humans three times in one month
C. a boy was attacked by a shark at a Sydney beach
D. shark numbers are increasing in the waters off Sydney"s beaches
B. dragged
C. bit
D. packed
B. Sydney harbor is not far from the famous Opera House.
C. There are many locals and tourists on its coast all the year round.
D. There are few shark species in the waters off Sydney"s beaches.
B. he was very nervous when he was sent to hospital
C. he may be in danger of losing his leg
D. he was injured in the right leg
B. a ban on commercial fishing has increased fish numbers
C. many shark species are protected in Australian waters
D. the film Jaws has made the Great White famous
We"ve used the wind as an energy source for a long time.The Babylonians and Chinese were using wind power to pump water for irrigating crops 4000 years ago, and sailing boats were around long before
that.Wind power was used in the Middle Ages, in Europe, to grind (磨碎) corn, which is where the term "windmill" comes from.
We can use the energy in the wind by building a tall tower, with a large propellor on the top.The wind
blows the propellor round, which turns a generator to produce electricity.
We tend to build many of these towers together, to make a "wind farm" and produce more electricity.The more towers, the more wind, and the larger the propellors, the more electricity we can make.It"s only worth building wind farms in places that have strong, steady winds, although boats and caravans (大篷车) increasingly have small wind generators to help keep their batteries charged.
The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains-places where the wind is strong and reliable.Some are offshore.To be worthwhile, you need
an average wind speed of around 25 km/h.Most wind farms in the UK are in Cornwall or Wales.Isolated places such as farms may have their own wind generators.In California, several "wind farms" supply
electricity to homes around Los Angeles.
The propellors are large, to obtain energy from the largest possible volume of air.The blades can be
angled to cope with varying wind speeds.Some designs use vertical turbines (垂直涡轮机), which don"t
need to be turned to face the wind.The towers are tall, to get the propellors as high as possible, up to
where the wind is stronger.This means that the land beneath can still be used for farming.
B. the source of wind power
C. the nations using wind power
D. the history of using wind power
B. The tall tower helps turn the energy in the air into electricity.
C. Warm air rises and makes the propellor move round.
D. The propellor blown round by wind turns the generator to produce electricity.
B. isolated farms don"t have enough electricity
C. there are less human activities
D. the wind is strong and reliable
B. wind farms need no fuel because wind is free
C. the blades can be angled to turn to face the wind wherever it comes from
D. the higher and larger the towers are, the stronger the wind is
B. ABC of the using of wind energy
C. How to make best use of wind
D. Wind energy is the best energy
traditional public schools.In the United States the rules for charter schools differ from state
to state.But in general these schools have greater freedom to decide what to teach and how
to teach it.
The "charter" is a performance contract.It establishes the goals of the school and other
details like how student performance will be measured.Fortyseven million students attend
traditional public schools.But more than a million students attend charter schools.
And now a group of charter schools have formed the Green Charter Schools Network.
The idea is to have environmentally friendly school buildings but to also go further than that.
The schools teach students to become involved in community issues that affect them and
the environment.For example,young children grow crops in a school garden and learn
about healthy eating.Older students help recycle waste from the cafeteria.And local schools
share what they grow in community gardens with people in need.
Jim McGrath is president of the Green Charter Schools Network.He says there are
about 200 "green" charter schools across the United States.He says the plan is to also
include traditional public schools as well as private schools.
Jim McGrath:"The most important thing is that every one of us-every child,every
adult-has a responsibility that their action,every action we make has an effect on the earth
that we live in.And that our natural resources are not unlimited.And that if we want a
positive earth for future generations,we all need to make commitments to be agents of
change so that we don"t destroy our natural resources."
T he Green Charter Schools Network holds its first national conference this October
in Minnesota.It will include companies and organizations like Waste Management and the
United States Green Building Council.We sincerely hope that their goal is to expand the
movement across the country.
B．they still use the traditional rules
C．they have more freedom in management
D．they attract more students than others
B．paint the school buildings in the color of green
C．measure the students with the same standards
D．get students involved in environment friendly activities
B．It holds its first national conference in Minnesota
C．It will benefit both the schools and the communities
D．It promotes different schools to share their achievements
B．natural resources are abundant for people to use
C．students should be taught to be responsible for the world
D．everyone should make efforts to change the positive nature
B．To encourage the students to adopt healthy eating.
C．To inspire people to recycle waste from the cafeteria.
D．To arouse the schools to take action to protect the earth.
