Long sentences(simple sentence, compound
sentence, complex sentence, compound and complex sentence)
Example: paragraph threeExample: paragraph three If we accept that we cannot prevent science and technology
from changing our world, we can at least try to ensure that the changes they make are in the right directions. In a democratic society, this means that the public needs to have a basic understanding of science, so that it can make informed decisions and not leave them in the hands of experts. At the moment, the public is in two minds about science. It has come to expect the steady increase in the standard of living that new developments in science and technology have brought to continue, but it also distrusts science because it doesn’t understand it. This distrust is evident in the cartoon figure of the mad scientist working in his laboratory to produce a Frankenstein. It is also an important element behind support for the Green parties. But the public also has a great interest in science, particularly astronomy, as it shown by the large audiences for television series such as The Sky at Night and for science fiction.
