Computer technology is advancing dramatically since its invention and has shown some possibility of intelligence, which means (that) they are capable to think, and therefore make judgment and initiate action in complex situation, featuring like human brains. This excites many people while arousing some concern about its hidden hazard to human being. (定语从句，宾语从句，非谓语，)

Of course those optimists have their own reasons. The first one is that intelligent computers would free human labor to an enormous extent. They would replace human workers in many walks of life, performing many tasks in medical procedure, manufacture, domestic service, space and ocean exploration and so on. They can work more efficiently, accurately than human counterparts and they never feel tired or fear any danger. It is claimed that these advantages would increase the productivity of the whole world for long run and bring human comfort and convenience. (表语从句，非谓语，比较句型，并列句，形式主语)

However it also makes sense to worry about the potential risk that computational intelligence may impose on human race. It is generally believed that employment rate would decline if artificial intelligent machines are widely applied to substitute for human labors. Correspondingly, the wealth gap can be inferred wider. In addition to economic impact, human community may increase dependence on smart technology, losing some basic living skills or life experience. Some pessimists show their concern about ethical issue in literature involving robots which are likely to manipulate humans. Nonetheless, many people hold the belief that no matter how intelligent a computer is, it is programed by human being and is under human’s control for sure. (形式主语，被动句，定语从句，条件状语从句，非谓语，同位语从句，让步状语从句)

Based on the discussion above, I personally think that whether advanced technology can benefit human race or not is determined by how we human utilize it. Technology is supposed to be neutral and has no threat on human designers. If we put it to good use, then we would make the most of technology. (非谓语，宾语从句，主语从句，被动句，条件状语从句)
