Nowadays many people complain that they have difficulties getting enough sleep. What problems can lack of sleep cause? What can be done about lack of sleep?

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

 

Student answer (Band 6.5)

Sleep is quite essential and these days a lot of people complain that they have sleep issues. Though, sleep issues can happen because of different reasons, but nevertheless, lack of sleep can cause various issues and here I would like to discuss about those issues and how to improve your sleep.

Getting sufficient sleep is quite important, but if for some reason, you are unable to get enough sleep, you could face a lot of problems. Even the most mundane tasks become difficult, if you are suffering from lack of sleep. It gets hard to focus. For some people, it could even cause digestion issues. I remember that when I had a child, a couple of years back, I could not sleep properly. That really made me dysfunctional during the day and it was very hard to concentrate on work or even take care of the child.

Good news is that there are various ways to manage sleep and improve your sleep cycle. First of all, I would suggest to monitor your sleep as that could give you a better analysis of how you are sleeping during the night. You can do that either using advanced fitness devices, which help you track your sleep or you can go to sleep clinics, depending on the seriousness of your problem. That should give you a fair idea about how you are sleeping. Then, there are various ways to calm yourself before you go to bed. For example, you can have chamomile tea which has been known to soothe the nerves in your brain. Another affective way is to jot down your thoughts in a journal before you go to bed. That can also help you to clear your mind.

I would like to conclude that sleep is very important and sleep apnea can cause some serious issues which can prevent you from completing your day to day activities. It should be managed as early as possible to prevent a permanent damage.

Task Achievement / Task Response — Band 6.5

You have addressed both parts of the prompt: the consequences of sleep deprivation and potential solutions. Your ideas are relevant, and the inclusion of a personal example regarding your child adds a nice touch of authenticity. However, the development of your ideas is somewhat limited. For instance, the discussion on consequences could be expanded beyond 'digestion issues' and 'focus' to include long-term health risks like cardiovascular disease or mental health impacts. Similarly, while your suggestions for solutions are practical, they could be explored in greater depth to demonstrate a more sophisticated understanding of the topic. Overall, you have provided a clear response, but more detailed elaboration would elevate the score.

Coherence and Cohesion — Band 7.0

The essay is logically organized with a clear introduction, body paragraphs, and a conclusion. You use transition signals such as 'First of all', 'Then', and 'For example' to guide the reader through your arguments. Paragraphing is used appropriately to separate the problems from the solutions. However, some cohesive devices feel a bit mechanical or repetitive. For example, the phrase 'sleep issues' is used frequently, and the transition between sentences could be smoother to create a more natural flow. Improving the variety of linking words and ensuring that referencing is precise will help you achieve a higher band score in this criterion.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'dysfunctional', 'soothe', and 'monitor'. However, there are some instances of imprecise word choice, such as 'affective' instead of 'effective' and 'permanent damage' which is slightly awkward in this context. You also rely on somewhat generic phrases like 'quite important' and 'various ways'. To reach a higher band, try to incorporate more precise, topic-specific collocations and avoid repeating the same basic vocabulary. Your spelling is generally accurate, and the meaning is always clear, which is a positive aspect of your writing.

Grammatical Range and Accuracy — Band 6.5

You use a mix of simple and complex sentence structures, such as conditional sentences ('if for some reason, you are unable...') and relative clauses. While your grammar is generally clear, there are some minor errors, such as 'I would suggest to monitor' (should be 'suggest monitoring') and the redundant use of 'about' in 'discuss about those issues'. Punctuation is generally sound, though some comma usage is slightly inconsistent. The majority of your sentences are error-free, but to reach a higher band, you should aim for more complex sentence variety and ensure that your verb patterns are consistently accurate.
