2.
写作技巧
本单元的写作要求是对未来生活的变化经行描述，写预测未来的短文应用到一般将来时，就某一个话题展开充分、合理的想象。写此类短文需要注意以下几点：
(1)介绍未来的生活时，多用一般将来时进行描述，且多用表示将来的时间状语；
(2)写作重点要突出“变化”，
即将来的生活与现在的生活相比发生了什么样的变化。不要遗漏提示要点;
(3)写作层次要清晰、语言流畅，想象合理。
(4)另外，短文中可以用比较级的结构，增强与现在的对比效果。常见的预测未来的话题有：机器人、电脑、环境、旅游、学习、工作和日常生活等。
(5)预测未来常用的句型有：
There
will
be
…
People
will
…
Sb
think
(s)?
that
…
3.
写作应用
以“Life
in
the
Future”为题写一篇短文，对未来的生活进行预测，注意一般将来时的使用。词数：100左右。
写作思路点拨：
(1)时态：以一般将来时为主；
(2)人称：本文是介绍未来人们的生活，应以第三人称为主；
(3)写作思路：本文是预测未来的短文，可以分别就学习、工作、旅行、业余生活等方面对未来进行预测。可运用本单元所学的内容，如There
be
句型的一般将来时，live
to
be
等固定结构；
注意事项：
(1)正确运用一般将来时的各种句式；
(2)正确运用There
be
句型的一般将来时；
(3)叙述时要条理清楚，注意和现在的对比；
