CÂU ĐỀ BÀI:The diagram illustrates the process that is used to manufacture bricks for the building industry.
CÂU VIẾT LẠI:
The flow chart shows how bricks are produced for, and delivered to the building industry
Overview
Overall, there are 7 stages in the whole brick producing process, beginning with clay excavation and ending with the delivery of the bricks to the customers.Thân bài
Firstly, clay is dug up by using a big digger. To get rid of the oversized pieces, clay is placed on ametal grid and small pieces drop onto a large roller. At the next stage, sand and water are added to the clay. After the bricks are shaped by using a wire cutter or a mould, they are moved to a drying oven for 24 to 48 hours.
Those bricks are then fired in a special kiln at a moderate temperature (200c - 980c) at the fourth step. Afterwards, they continue to be heated for the second time at a higher temperature (870c - 1300c) in another kiln. Before being packaged at the sixth stage, the bricks are treated in a cooling chamber for 48 to 72 hours. The entire brick producing process concludes after the bricks are delivered to customers.

The diagrams below show the stages and equipment used in the cement- making process, and show how cement is used to produce concrete for building purposes.
The given diagrams illustrate the production of cement, and how to use cement to make concrete.
It is clear that there are five main stages in the process of making cement; meanwhile, only two steps are required to produce concrete.
At the first stage of producing cement, limestone and clay are put through a machine called crusher and become power. This power is then mixed and is brought into a rotating heater where it is heated in high temperature. The process continues with grinding the material and then cement is produced. At the final stage, cement is packaged into bags and is ready for the production of concrete.
Moving to the production of concrete, the first step is combining different materials – water, sand and small stones in the proportions of 10%, 25% and 50% respectively. This mixture is next put into a concrete mixer in order to become final concrete which can be used for building purposes.

The diagram illustrates the various stages in the life of a honey bee. We can see that the complete life cycle lasts between 34 and 36 days. It is also noticeable that there are five main stages in the development of the honey bee, from egg to mature adult insect.
The life cycle of the honey bee begins when the female adult lays an egg; the female typically lays one or two eggs every 3 days. Between 9 and 10 days later, each egg hatches and the immature insect, or nymph, appears.
During the third stage of the life cycle, the nymph grows in size and sheds its skin three times. This molting first takes place 5 days after the egg hatches, then 7 days later, and again another 9 days later. After a total of 30 to 31 days from the start of the cycle, the young adult honey bee emerges from its final molting stage, and in the space of only 4 days it reaches full maturity.
