Some people think international cooperation has brought benefits to world environment protection, while some people think more benefits has been brought to international business. Discuss both views and give your own opinion.

The concept of
temperature
has evolved from the common concepts of hot and cold. Human perception of what feels hot or cold is a relative
one
.
For example
, if you place
one
hand in hot
water
and the other in cold
water
, and
then
place both hands in tepid
water
, the tepid
water
will feel cool to the hand that was in hot
water
, and warm to the
one
that was in cold
water
. The scientific definition of
temperature
is less ambiguous than your senses of hot and cold.
Temperature
is operationally defined to be what we measure with a
thermometer
. Two accurate thermometers,
one
placed in hot
water
and the other in cold

, will show the hot

is the quantity measured by a

. Any physical property that depends on
temperature
, and whose response to

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
