Extraction of main reading points
General argument: Research shows that high concentration of lead caused poisoning death of naval Arctic expedition. Some people think they ate canned food containing lead. However, the author refutes this view.
Reason one: not a lot of lead enters food. In the19th century, people sealed food cans with molten lead. People seal the lid from the outside of the can, so there is little possibility that lead will contact the food in the can.
Reason 2: There are no other similar cases. Many other British fleets also use lead to seal canned food. However, none of them had lead poisoning.
Reason 3: It may be that sailors drank lead-containing water. Franklin's ship has a special water purification system to filter potable fresh water. However, the water pipes of the water purification system are made of lead.
Extraction of key points in listening comprehension
General argument: The source of lead poisoning of expedition members is canned food.
Explanation 1: The way the canned workers seal the lid is very careless. In fact, workers don't have enough time to produce canned food. Due to the urgent time, the workers were not very careful when sealing, resulting in lead not outside the lid, but flowing into the food in the jar.
Explanation 2: Other British fleets did not report lead poisoning because they did not check for lead poisoning. Without professional examination, lead poisoning is difficult to find. Symptoms of mild lead poisoning include fatigue and headache, but these two are very common, so many people will ignore these symptoms.
Explanation 3: The fresh water purified by the water purification system is for engines, not for sailors. The engine on the ship is a steam engine, so fresh water must be used. At the same time, on board, they have another drinking water supply.

Several explanations of crew poisoning
Views on reading the article:
1. It is unlikely that the food in the can will be polluted, because it will only pollute the outside of the can.
There are no reports of crew poisoning in other places.
The possible explanation is that drinking water is polluted.
Listen to the rebuttal:
1. Time pressure makes workers very concerned, so it is still possible.
2. No report doesn't mean it didn't happen. Perhaps the symptoms of poisoning are too common to be detected.
3. Water is used in machines. The crew don't drink. They have their own drinking water system.
Memories of New TOEFL Writing Topics Fourth Edition;
Reading: Canned food is the cause of lead poisoning and crew death.
Be careful that the lead fixed on the can will not touch the food.
No other evidence of the crew's death was found on another ship.
The water purification system may be the source of poisoning.
Listen:
The company has limited time to finish the work. Workers are under pressure of time, so it is reasonable for them to fill the cans with lead carelessly and hastily.
Sailors may be affected, but there is no report. First of all, it is difficult to judge whether sailors are affected by lead without careful testing. Second, the symptoms of lead poisoning are very common, such as feeling tired or having a headache, and they are easily overlooked.
The water in the purification system is used for ship engineering, because salt water cannot be used. Water used for cooking and drinking comes from different sources.
New TOEFL comprehensive writing model essay:
Read the instructions that lead in canned food can lead to crew poisoning. On the contrary, the professor thinks that the arguments in reading are not convincing.
First of all, the author mentioned that lead did not enter the food, because the molten lead was carefully coated on the can from the outside to seal the lid. However, the spokesman said that the tank on board showed that the molten lead was not left outside as expected. In fact, workers in food companies don't have enough time to seal the lid carefully. Therefore, the molten lead flows into the can and pollutes the food.
In addition, the author proves that there are no other reports of lead poisoning. In fact, the speaker pointed out that the sailors on other ships did not carry out lead poisoning tests, but lead poisoning was difficult to detect without specific tests. The reason is that the symptoms of mild lead poisoning include fatigue and headache, which is very common. Therefore, other sailors may ignore these signs and fail to identify these problems.
Finally, the speaker contradicts the viewpoint in reading. He thinks that the main purpose of the water purification system is to provide fresh water for the engine, not for drinking or cooking. This is because those engines are steam engines and they must use fresh water. In addition, there is a separate fresh water supply on board for drinking and cooking.
