Task 1

Integrated writing

Topic

Metal lead caused death of crew members

R&L comparison

Reading:

1. It is unlikely that the food in the can was contaminated because the lead is on the outside;

2. There are no reports of poisoning of crew members on other ships;

3. Water Contaminated.

Lecture: Refutation

1. Work pressure causes crew members to be careless, which may contaminate food;

2. Symptoms caused by poisoning are similar to common diseases , the report cannot be accurately determined;

3. The crew has their own drinking water system, and the contaminated water is used for machinery.

Extract the main points of reading

General Argument: Research shows that high levels of lead caused poisoning deaths among naval expeditions to the Arctic. Some people believe they ate canned food that contained lead. However, the author refutes one point.

Reason 1: There is not a large amount of lead entering the food. In the 19th century, people used melted lead to seal food cans. The lid is sealed from the outside of the can, so the possibility of lead coming into contact with the food inside the can is very small.

Reason 2: There are no other similar cases. Many other British fleets also used lead to seal canned goods. However, none of them had lead poisoning.

Reason 3: The sailors may have mixed lead-containing water. Franklin's ships all had a special water purification system to filter out drinkable fresh water. However, water pipes in water purification systems are made of lead.

Extracting the main points of listening

General argument: The source of lead poisoning in expedition members is canned food.

Explanation 1: Canned food workers seal lids in a very sloppy way. In fact, workers did not have enough time to produce canned goods. Due to time constraints, the workers were not very careful when sealing, resulting in the lead not being on the outside of the lid, but flowing into the food in the jar.

Explanation 2: The reason why there are no reports of lead poisoning in other British fleets is because they did not check themselves for lead poisoning. Lead poisoning is difficult to detect without professional inspection. Symptoms of mild lead poisoning include fatigue and headaches, but these are so common that many people ignore them.

Explanation 3: The fresh water purified by the water purification system is for the engine, not for the sailors to drink. The ship's engine was a steam engine, so fresh water was necessary. Meanwhile, on board the ship, they had an additional supply of drinking water.

INTEGRATED comprehensive writing

Several explanations for crew poisoning

Read the article views: < /p>

1. It is unlikely that the food inside the can was contaminated, as it will only contaminate the outside of the can

2. There are no reports that crew members elsewhere were also poisoned

3. The possible explanation is that the drinking water is contaminated

Listening rebuttal:

1. Time pressures make workers careless, so it is still possible

2. No The report does not mean that it did not happen. It may be that the symptoms of poisoning are too common and difficult to detect

3. The water is used for machines and the crew does not drink it. They have their own drinking water system

New TOEFL writing question recall version 4:

Reading: whether the canned food is the poison factor that contributes to the leading and the death of crew in Ka a ship.

The lead that was carefully stilled to the can would not contact the food.

No other evidence of death of the crew was found in other ship.

Water purification system may be the source of poisoning. < /p>

Listening:

Company has limited time to finish this work. Workers are under time pressure and it is reasonable that they are careless and apply lead to the cans in a hurry way.

p>

Sailors may be affected but they are not reported. First, it is difficult to judge whether sailors are affected by lead without careful tests. Second, the symptoms of lead poisoning are common, such as feeling tired or headache and they can be easily overlooked.

The water in the purification system is used for ship engineering since the salt water cannot be used. The water for cooking and drinking comes from a different way.

New TOEFL comprehensive writing sample:

The reading states that the lead in canned food cause the crew poisoning. On the contrary, the professor thinks that the arguments in reading aren't convincing.

Firstly, the author mentions that lead didn't get into food because melted lead was carefully applied to cans from the outside to seal the lids in place. However, the speaker says that the cans on ships show the melted lead didn't stay on the outside as it was supposed to. In fact, the workers in food company didn't have enough time to seal the lids carefully. So, the melted lead ran down the inside of the cans, contaminating the food.

Additionally, the writer demonstrates that there are no other cases about lead poisoning reported. As a matter of fact, the speaker indicates that sailors on the other ships didn't test for lead poisoning but lead poisoning is difficult to detect without specific tests. The reason is symptoms of mild lead poisoning include tiredness and headaches, which are very common. Therefore, other sailors might overlook the signs and couldn't recognize the problems.

Finally, the speaker contradicts the idea in reading by suggesting that the main purpose of the water purification systems was to provide freshwater for the ships engines instead of drinking or cooking. It is because those engines were steam engines and they must use freshwater. Moreover, there are separate supplies of freshwater on board for drinking and cooking.
