Read the following excerpt from a student essay. How can the writer best improve his or her grammar and mechanics?
People around the world have always encountered frogs and toads in various bodies of water. Unfortunately, pollution and disease is killing many of the world's frogs. For example, a fungus may be responsible for the extinction of several species in Australia and has been found in forty-four species there.

During peer review, you read and respond to a fellow student's writing. While there are many methods and strategies that you can use for reviewing a text, it is generally helpful to frame your suggestions in concrete and constructive ways and to consider the following areas for revision:
Ideas and development: Does the writer express a clear idea and develop it with evidence, examples, or analysis?
Organization: Does the writer order ideas in a clear, logical way so that they build on one another and are easy to follow?
Voice: Does the writer maintain an appropriate voice, such as a formal and objective voice in an academic essay or an engaging and expressive voice in a narrative essay?
Sentence fluency: Does the writer use sentences that vary in structure and length to create a sense of rhythm and flow within and between sentences, or does the writing sound choppy, rambling, or repetitive?
Word choice: Does the writer use words accurately and precisely to create clear, effective, and engaging writing?
Grammar and mechanics: Does the writer follow appropriate conventions, using accurate spelling, punctuation, and grammar to create writing that is correct and easy to read?
The writer could best improve his or her grammar and mechanics by fixing subject-verb agreement errors.
For example, the writer could replace the underlined words with the correct verb forms: pollution and disease kill and the effect of pollution is.
