無標(biāo)題文章

附: 視頻中講到的流程圖

視頻的筆記如下:

一個流程包含4個部分

1. 原材料(raw materials)

2. 設(shè)備(equipment)

3. 處理辦法(be done)

4. 產(chǎn)物或中間產(chǎn)物(product)

Introduction: 一個流程包含幾個步驟

The first diagram illustrates that there are ?five steps in the process of making cement.

轉(zhuǎn)移/運輸: transport; transfer; send; bring

1.中間段落的第一句話交代原材料

As for cement making, limestone and clay are the raw materials used in this process.

2. 任何一個設(shè)備的后面都可以跟where從句(請注意where前面有一個逗號)

In the first stage, limestone and clay are sent to a crusher, where they are crushed to ?produce powder.

3. 任何兩個步驟之間都可以使用once/after( 一旦…)進(jìn)行連接

Once/after the powder is mixed in a mixer, it is further transported to a rotating heater, where it is heated for sometime.

4. 任何兩個步驟之間也可以使用after which進(jìn)行連接

Then the powder is mixed in a mixer, after which it is further transported to a rotating heater, where it is heated for some time.

5. 任何一個產(chǎn)物的后面都可以跟一個非限制性定語從句(, which)

In step four, the mixture is grinded by a grinder and at the same time it is manufactured to cement, which also needs to be packed into bags in the final stage.

6. 寫好連接過渡詞

In the first stage, At the beginning;

the whole process begins at

After that; then

In step two; in the second step

The third step involves……

The whole process ends at…

流程圖的結(jié)尾

1. 2 diagrams- 比較兩個流程的異同酬蹋,或者復(fù)雜程度

All in all, the process of cement making is more complex than that of concrete production as it involves more steps.

2. 1 diagram- 哪一個步驟最復(fù)雜因為什么原因

All in all, the third step of cementproduction is more complex than others as it requires a higher temperature.

任務(wù)三:流程圖寫作

流程圖參考文章

The diagrams illustrate the stages and equipment used to produce and recycle glass containers.

It is apprarent that the process of glass production starts with mixing raw materials, including sand, soda ash, limestone and some other chemicals. Once mixed, the mixture is transported to a glass furnace, where it is melted at 1500°C. In step three, the molten glass obtained is shaped to various forms by blowing and a variety of glass containers are produced finally.

The process of recycling glass containers starts from collecting the used glass, after which the recycled material is sorted by color and then washed to remove impurities. The following stages involve crushing the used glass and then melting it to molten glass. Finally, new glass products could be manufactured by moulding the molten glass.

All in all, the process of recycling glass containers is more complex than producing new ones as it involves more steps.
