TEST 3

Task 1

The process given by the flow charts is about the details steps and facilities which are utilized in the production of cement and concrete.

As for the first chart,cement production involves the following steps. At first, limestone and clay are set into a crusher, by which they become powder. After being mixed, the powder is transmitted into the next rotating process and it will be heated. Next, the mixture goes into the grinder where the cement comes out. Finally, the cement can be packed in bags.

In terms of concrete production, in the first step, 25% sand and 50% sand and 50% small stones are put together, with a combination of 15% cement and 10% water. In the next stage, the mixture can be poured into a concrete mixer. Finally, the production of concrete is successfully completed.

All in all, it is clear to see that compared with the production of cement, that of concrete is rather simple.

Task 2

Traffic jams have become a permanent reality in many metropolises. The government has conceived of a wide range of ways to deal with traffic congestion, but all the proposed solutions seem ineffective when confronting the soaring number of vehicles on the road. Some people hold that increasing the price of gas would be the best way to reduce traffic. Personally, i am skeptical of such a viewpoint.

First of all, we cannot indubitably attribute traffic jams to an increase in private car ownership. It is possible that poor road condition or traffic light layout may also give rise to this problem.

Second of all, with the technological progress of automobile manufacturing, more and more people can afford their own cars. As a result, the number of inexperienced drivers is also rising. Consequently, traffic accidents caused by these drivers lead to enormous traffic problems.

The government should encourage consumers to buy cars powered by green energy, which cuts down on pollution and makes the environment better for citizens.

Improving public transportation systems will work in the long run. For instance, developing a subway system is widely considered a very effective method for coping with the growing volume of traffic.

Overall, reasons for growing traffic problems are complicated. Increasing the price of gas is by no means the most reasonable or effective course of action. We should take a wide range of measures mentioned above into consideration. Moreover, the government and individuals have to join forces to address the problems with cooperation effort.
