Task 1

Đề bài

The diagram shows a method of shaping glass containers.

Sample

The diagram provides a breakdown of how glass containers are shaped. Overall, the process is comprised of 9 steps during which glass is melted, shaped using two different kinds of mould, heated, cooled, inspected and packaged.

The process commences when glass is melted in a furnace to 105 degrees Celsius. Thereafter the molten glass is placed into a trapezoidal mould in which it is pressed by the use of a pointed-tip tool. The thick-walled container formed as a result of the previous step is then attached to a second, curvy-at-the-bottom mould, and with natural airflow, the container’s bottom is naturally expanded.

The process continues with the containers being heated in a kiln at 482 degrees Celsius, after which they are cooled down for an hour at 25 degrees Celsius. Ultimately the containers undergo visual inspection during which high-quality ones are packaged, and low-quality ones are discarded.

Đề bài

Some people think more money should be spent on researching for other planets to live, such as Mars. To what extent do you agree or disagree with this statement?

Sample

Some people are of the opinion that more investment should be diverted to seeking habitable planets. However, I do not believe this to be a wise approach, for ventures into space is unpromising, and improving lives on Earth is more cost-effective.

The prospects of discovering planets with environments hospitable to lifeare grim. Indeed, lot of research has been conducted on seeking extra-terrestrial life forms by SETI and NASA, and what scientists have discovered until now is no more than ambiguous traces of water and bacteria on Mars. It might take another thousands or even millions of years for humankind to find new planets. in a worst-case scenario, we may not be able to find anything at all.

Additionally, I think money should be better spent on improving the Earth. On the one hand, space research is costly, as facilities and equipment required to carry out research in space may billions of dollars, not to mention the expenditure on regular maintenance. On the other hand, measures to improve Earth’s current conditions cost much less and bring a lot more tangible benefits. Conglomerates with green credentials have environmental schemes, some of which have been successful to a certain degree such as Apple Inc.’s efforts to cut down on carbon footprint. Even individuals can contribute to the environment through small, inexpensive acts such as growing trees or recycling materials.

In conclusion, my firm conviction is that that putting our future hope into space research is somewhat unrealistic, and governmental budget is better spent on healing the Earth.
