TOEFL Writing Task 1 [Integrated Task] – Practice Test #040

This TOEFL Writing Task 1 (Integrated Writing) practice test provides an authentic experience with a real reading passage and a corresponding audio lecture. Follow the instructions carefully to simulate the exam and assess your skills accurately.

TOEFL Integrated Writing Detailed Instructions

Read the passage: You will read an academic passage on a topic, usually about 3 minutes.
Listen to the lecture: After reading, you will hear a lecture on the same topic, presenting a different perspective or additional information. You will not be able to see the reading passage while listening.
Take notes: While reading and listening, take notes on the key points and main ideas. Most of your focus should be on the lecturer since the passage is already available for reference.
Refer back to the reading: You can review the reading passage after the listening portion is complete.
Stay objective: Avoid adding personal thoughts, agreeing or disagreeing with the speaker, or evaluating the quality of their arguments. The key is to remain neutral and accurately report what each source says. Think of yourself as a reporter: your task is to explain what each side claims, how their points relate to each other, and how the lecture challenges the reading.
Organize clearly and have a plan: Use clear structure with an introduction, body paragraphs, and a conclusion. Personally, I prefer writing a concise introduction that presents both sides and briefly states their main reasons, followed by three body paragraphs, each focusing on one point and discussing it from both perspectives. If done properly, there’s no real need for a conclusion, especially since this isn’t a personal or opinion-based essay.
Write your response: Summarize the main points from the lecture and explain how they relate to or challenge the points in the reading passage.
Stay within the word limit: Your response should be 150-225 words.
Proofread: Ensure your grammar, spelling, and sentence structure are accurate.
Submit your writing: Use the form below to privately submit your writing for review, or post it publicly in the comment section at the bottom of the page.
Feedback (optional): Order detailed written analysis or a video session to review your response using the official TOEFL writing criteria and identify specific areas for improvement.

Reading Passage

The zebra mussel, a freshwater shellfish native to Eastern Europe, has been spreading beyond its original range and has now reached parts of North America. This invasion appears to be unstoppable, and it poses a serious threat to freshwater fish populations across the continent.

First, the history of the zebra mussel’s spread suggests that halting its invasion may be impossible. Its spread has been largely due to human transportation. From its native habitats in Eastern Europe, the zebra mussel spread through new canals connecting Europe’s waterways, often attaching to ships or surviving in the ballast water that ships carry for balance. By the early 19th century, the mussel had spread throughout Europe and later reached North America’s east coast in the ballast water of European ships. This pattern of spread indicates that zebra mussels are likely to colonize all of North America.

Secondly, zebra mussels tend to dominate new habitats once introduced. They are resilient, can thrive in a variety of conditions, and reproduce rapidly. Crucially, zebra mussels often encounter no natural predators in their new environments, allowing them to dominate ecosystems where they are introduced.

Finally, zebra mussels are likely to harm freshwater fish populations in the areas they invade. Since zebra mussels consume plankton, they compete for food with many fish species, potentially leading to a decline in fish populations where the mussels become dominant.
