1
Refining begins with a process called distilling.
2
After oil is superheated, it becomes vapor.
3
The vapor is fed into the distillation unit.
4
As it rises and cools, the vapor turns back into a liquid.
5
Using stacks of trays, the liquid is easily collected and separated by weight.
6
The lighter and medium weight liquids require less processing before they're ready to be used in cars and trucks.
7
The heavier liquids need more processing to become useful.
8
A process called cracking is used to maximize the usefulness of heavy oil.
9
Heavy oil has long strings of carbon and hydrogen molecules.
10
using a catalyst these molecules can be broken into smaller
11
chains transforming the heavy oil into lighter more valuable fluids reforming is a process
12
that increases the amount of gasoline produced from crude oil one
13
of the products separated in the distilling process is a liquid called naphtha.
14
The number of carbon atoms in naphtha is about the same as the number found in gasoline, but their structure is more complex.
15
Reforming rearranges the naphtha molecule, turning it into a usable, gasoline -like molecule.
16
Blending is a process of mixing different refinery products to make finished petroleum fuels.
17
Gasoline, for example, is blended to achieve octane standards, creating the grades of gasoline you see at the pump,
18
regular, mid -grade, and premium that are necessary to meet the needs of specific engine types.
19
Treating is a process used to produce cleaner gasoline, which helps protect both the environment and our health.
20
Gasoline molecules contain impurities like sulfur that can be removed.
21
When the molecules are heated and come in contact with a special catalyst, a chemical reaction occurs that strips the sulfur away.
22
These sulfur compounds are used as fertilizers and in pharmaceuticals.
23
Nothing goes to waste in a refinery.

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
