Have you ever  listened about global warming? Global  warming is becoming a more serious problem and 
has  become a threat  
to our planet. So I  will tell you how we can stop global warming.  
Global warming is making our world a dangerous place and it is destroying the world. 
Global warming is caused by the greenhouse gases  that are left by  factories, 
cars, motorbikes etc. The  air is polluted  from factory emissions  and car exhaust. 
Because of the greenhouse gases there is 
acid rain. Acid rain  destroys lakes 
and rivers and affects the fish and wildlife. 
Due to global  warming the ozone layer is depleting  and the harmful ultraviolet rays are reaching the earth. This 
causes the glaciers and icebergs to  melt. 
First, we have work together to reduce, reuse and recycle to stop the  causes of global warming. 
One of the things we could do is recycle more. Recycling is 
the  process in which we could reuse things like cardboard, plastic bottles and  plastic bags. 
For example we could use  both sides of a piece of paper. Even more 
useful,  would be to buy washable water bottles  that can be reused. 
Finally we can buy  goods with less packaging  and we could carry cloth bags to carry our  
groceries and purchases instead of wasting plastic bags.  
Next we need to find more  different types of energy to use as another step to stop the effects of global  warming. Using more solar, wind and hydroelectric 
power would reduce pollution and consumption  of fossil fuels. 
Less gas and coal would be burned if  people used alternate power sources. As well we can use public 
transport instead of driving alone in individual cars. 
If people prefer not to take the bus  or train they could walk or ride a bike.   
There are  other ways to put global warming in check. One is to plant more trees and stop deforesting.  More trees produce more oxygen which benefits the 
ozone layer. Another way is to switch off electrical equipment when not in use would stop the wastage of precious electricity.  
When people  think about the concequences and how to help to prevent global warming and take  action we could stop global warming. This  would make our world 
a wonderful place to live.  
                              
   Selects from a broad range of words (threat, planet, polluted, emissions,  exhaust, acid rain, affects, wildlife, depleting,  glaciers, packaging, 
    instead, hydroelectric, pollution, fossil fuels, precious).
 
    Uses phrasal expressions (left by, switch off), conditional structures (Less gas and coal would be burned if people used alternate 
    power  sources.), and passive and active voice (Global warming is caused by the greenhouse gases ..., 
    Global warming is making ...).
 
   Writes a variety of sentence structures to  express relationships of time and condition (If people prefer not to take the bus or train they could 
    walk or ride  a bike.).
 
   Uses a variety of strategies to make effective  word choices (One is to plant more trees  and stop deforesting [deforestation].).
 
   Produces expository and narrative texts with a  developing sense of audience, genre, voice and degree of formality (First, we have work together to 
    reduce,  reuse and recycle to stop the causes of global warming.).
 
   	Connects ideas in a cohesive, well-developed  five-paragraph academic composition using a variety of cohesive devices (Because, Due to, One of the 
    things,  Finally, For example, Next, As well, Another way, when).
 
   Edits and revises for punctuation conventions (?), (,) (etc.), appropriate word forms (useful, washable) and 
    word choice (consumption), content, organization (… and we could carry cloth bags to carry our groceries and purchases  instead of 
    wasting plastic bags.) and verb tense (has become, is destroying, could stop).
