traditional agriculture / but modern
techniques / make as much use of …as
possible / save / improve / grow better /
although, shortage / latest techniques /
in spite of / future agriculture / because ,
not only …but also …
Sample:
 Traditional agriculture in China didn’t
change much for thousands of years. But
modern techniques help farmers make as
much use of land as possible, they also
help farmers save time and allow farmers to
grow an extra crop in each season. Besides,
modern techniques help farmers improve
production and grow better and healthier
plants and fruit. Although the shortage of
arable land is the biggest problem of
Chinese farmers, Chinese scientists have
developed some latest techniques to solve
the problem, such as growing vegetables
in greenhouses, using GM. In spite of this,
future agriculture should depend on high
technology as well as traditional methods.
Because not only is food production
important but also taking care of the
environment is important.
