TOEFL iBT Practice Test 45

AI-generated practice paper in the style of TOEFL iBT — original material, not a reproduction of any real exam paper, following the official task types. Listening audio is read aloud by your browser's voice. For Speaking you can record yourself and compare with a model answer, and Writing tasks include a model answer — neither is scored automatically, since that needs real speech and writing evaluation this site does not offer for this exam.

Before the 1880s, every town set its clocks by the position of the sun. This caused few problems until rail made rapid travel possible. Timetables became a night, because a train leaving one city at noon would arrive in another whose clo showed a different time. In 1884, an international conference divi the world into twenty-four zones measured from Greenwich, Engl. Most countries adop the system within a few deca. Some nati, such as China, still use a sin zone across a vast terri.

Subject: Your car insurance renews soon Dear Ms. Patel, Your policy renews on 8 November at a new annual premium of $612, an increase of $40 from last year due to rising repair costs. If you make no changes, the policy will renew automatically and the amount will be charged to the card on file. To review other coverage options or cancel, please contact us at least five days before the renewal date.

1. Why has the premium increased?

2. What happens if Ms. Patel does nothing before 8 November?

Subject: Your flight time has changed Dear Ms. Kowalski, Flight AV204 on 14 October has moved from 6:45 a.m. to 9:15 a.m. due to a change in the aircraft schedule. Your seat and baggage allowance remain the same. If the new time no longer suits you, you may change to a different flight within 7 days at no extra charge, or request a full refund.

3. Why has the flight time changed?

4. What options does Ms. Kowalski have if the new time is inconvenient?

Read an Academic Passage

Read the passage and answer the questions.

CRISPR-Cas9 is a gene-editing tool adapted from a defence system that bacteria use against viruses. In nature, bacteria store short segments of viral DNA from past infections; when the same virus attacks again, an enzyme called Cas9 uses these stored sequences as a guide to find and cut the matching viral DNA, disabling it. Researchers realised that Cas9 could be programmed with a synthetic guide sequence to cut virtually any DNA sequence of choice, not just viral genes, at a precise location within a cell's genome. Once the DNA is cut, the cell's own repair machinery takes over, either disabling the targeted gene or, if researchers supply a template, inserting a specific new sequence in its place. This precision has made CRISPR far cheaper and faster than earlier gene-editing methods, transforming basic research and opening clinical possibilities: in 2023, regulators approved the first CRISPR-based therapy, which edits a patient's own blood stem cells to treat sickle cell disease. The technology is not without limitations, however. Cas9 occasionally cuts unintended, similar-looking sequences elsewhere in the genome—so-called off-target effects—and editing cells that will pass changes to future generations raises ethical questions that remain unresolved even as the underlying science matures rapidly.

5. According to the passage, how does Cas9 normally function inside bacteria?

6. As used in the passage, "off-target effects" refers to

7. What can be inferred about gene-editing methods used before CRISPR?

8. Why does the author mention the 2023 approval of a CRISPR-based therapy?

9. Which sentence best summarises the passage?

Write an Email

Write an email that responds to the situation.

You noticed that a public computer in the library is often out of order. Write an email to the library manager. In your email, do the following: - Describe the problem. - Explain how it affects students. - Suggest a solution.
Show sample answer
Model answer: Dear Library Manager, I am a regular user of the library, and I want to bring a problem to your attention. Over the past month, at least half of the computers on the second floor have been out of order, and the printer has been jammed most days. This is causing long queues, especially in the afternoon, and many students cannot complete their assignments or print them in time. Last Friday I waited forty minutes just to print a single document. I suggest repairing or replacing the oldest machines and putting a sign on the printer with the contact number for technical support. It might also help to add a few extra computers for the exam period. Thank you for looking into this. Sincerely, Fatima Rahman

Write for an Academic Discussion

Read the discussion and write a post that contributes to it.

Dr. Almeida: In environmental engineering, water scarcity is worsening in many regions. Should governments invest heavily in desalination plants to turn seawater into drinking water, despite the high energy cost and environmental impact of the brine waste? Renata: Yes, invest now. For coastal cities facing genuine drought, desalination is often the only reliable, weather-independent source of water, and renewable energy is making the process steadily cheaper. Joaquin: I'd be cautious. The concentrated salt waste dumped back into the sea damages marine ecosystems near the outflow, and the energy cost is still high unless it's powered entirely by renewables. Write a post that contributes to the discussion (at least 100 words).
Show sample answer
Model answer: I lean towards Renata's urgency, particularly for cities where drought has become a recurring, severe threat rather than an occasional inconvenience, since in those cases the alternative to desalination isn't a perfect solution but genuine water shortages affecting millions of people. Joaquin's environmental concerns are legitimate, though, and I don't think they should be brushed aside just because the need is urgent. I would support desalination investment specifically when it's paired with strict environmental requirements, such as diluting and dispersing brine waste properly and powering plants with renewable energy rather than fossil fuels, which addresses Joaquin's two main objections directly while still giving Renata's drought-stricken regions the reliable water source they need.
