Task Achievement / Task Response: Band 4.0
You identify the diagram as a water-clock process and give its broad direction, noting that it begins with turning on the tap and ends by emptying and repeating the process. However, the report responds only minimally to the task: most stages and key apparatus details are missing or unclear. For example, it does not explain covering the hole, the water reaching a constant level, or the measured levels per minute; the lower bottle and its calibration marks are also not described accurately. The phrase “the neck cut off” is too incomplete to convey the lower container’s role. The response is also 50 words below the required minimum, which leaves too little space to describe the process adequately. Include a clear overview and explain the stages in sequence.
Coherence and Cohesion: Band 4.5
There is a basic attempt to organise the report: an opening statement is followed by an overview and then a description using “Firstly” and “After that.” The start-to-finish sequence is also recognisable. However, progression becomes difficult to follow in the final paragraph, where “On the other hand” does not express a contrast and the stages are compressed together. Connections such as “Therefor” and “respectively” do not clarify how one action leads to the next. Paragraphing is present, but the ideas within the body are not arranged into a clear, complete sequence. Use simple chronological links—“Next,” “Once the bottle is full,” and “Finally”—and give each stage a distinct, understandable place in the process.
Lexical Resource: Band 5.0
The response uses a small set of relevant process words, including “process,” “level,” “tap,” “bottle,” and “hole,” so the general topic can be identified. However, vocabulary is basic and repetitive, and several spelling or word-choice errors make parts difficult to understand. Examples include “diagrame,” “wanter,” “stagers,” and “mesure.” Phrases such as “the water is goes” and “the fifth process is consider with” do not express the intended actions naturally. More precise process vocabulary would help distinguish the apparatus from the steps, for example, describing water as flowing or dripping and the lower bottle as collecting it. Check spelling and choose verbs that accurately name each action.
Grammatical Range and Accuracy: Band 4.5
You attempt to form connected sentences and use sequencing language, but the grammatical range is very limited and errors frequently affect clarity. For instance, “they were many several stagers” has problems with agreement and sentence construction, while “the water is goes” combines incompatible verb forms. The opening also lacks a complete, well-formed sentence, and the final sentence joins several actions without clear grammatical links. Capitalisation and punctuation are inconsistent, including the capital “It” after a comma and missing spaces after full stops. Practise accurate simple present forms for process descriptions, such as “Water flows into the bottle” and “The user removes a finger from the hole,” before attempting longer sentences. Clear sentence boundaries will make the sequence easier to follow.
