Some countries are developing their nuclear weapons these days, and it becomes a serious threat . But it is undeniable that nuclear technology is clean for the environment and offers . Therefore a lot of people believe that nuclear technology has more positive sides than its negatives. I personally disagree with the statement and the following essay will discuss . To begin with, even though nuclear power could be used as an alternative source of energy, but some parties could misuse the technology. Nuclear power plants can be used as propaganda by some countries, whereas they will tell the public that they only use the technology for power generation purposes. But, the public would never know what lies behind their plants, as they might be developing . And then, although nuclear power plants are and cheaper in cost, many people still believe that they are a serious threat to the surrounding areas. Some countries have tried to manage their nuclear power plants cautiously, but sometimes unexpected events happen and cause a serious effect on the surrounding areas. For example, it is undeniable that Japan is well known for its advanced, effective and modern nuclear technology. But in the year 2010, a tsunami had struck one of the country’s power plants, and as a consequence, it caused a leakage in the plants and many casualties were found. I believe that that weapon of much destruction is always a threat to the world and it is hard to believe that a weapon can maintain world peace. how the weapons have destroyed millions of lives and have caused severe damage to our environment. In conclusion, although nuclear technology could be used as a clean and cheap source of energy, I strongly disagree with it. Even though strict monitoring is made sure for , some countries might secretly use it as a weapon. And then, no matter how well the power plants are built, they could still be , as we could never predict that any natural disaster could hit these power plants anytime.

Overall assessment

Why this response received Band 6.5

The response maintains disagreement and develops relevant arguments about weapons and nuclear accidents. However, it is presented as one continuous paragraph, and repeated connectors make the progression mechanical. Recurring grammatical errors and some imprecise expressions also reduce the clarity and control of an otherwise understandable argument.

Task Response

7.0

The position is clear throughout and the two main arguments—weapon misuse and catastrophic accidents—are developed with relevant explanation and a concrete example, though some points lean on assertion rather than fuller support.

Coherence and Cohesion

5.5

The arguments about weapons and accidents follow an understandable sequence, but the entire essay is one paragraph. Frequent use of "But" and "And then" creates mechanical links, and the main arguments need clearer separation and grouping.

Lexical Resource

7.0

Vocabulary is generally sufficient and topical, with phrases like 'weapon of much destruction' and 'strict monitoring', though some collocations and phrasing are imprecise or repetitive.

Grammatical Range and Accuracy

6.5

A mix of complex structures is attempted with some success, but recurring errors such as 'even though...but', 'discuss in details', and tense or article slips are noticeable without blocking meaning.
