Learning Objectives

• Read texts about black holes, the event horizon and the singularity, and identify the main idea, key details and the writer's viewpoint.
• Use verbs followed by the to-infinitive and verbs followed by the gerund, including verbs that change meaning (remember, stop, try).
• Review active and passive voice in science reporting.
• Listen for gist and detail in broadcasts about black holes and separate facts from misconceptions.
• Write a news report about the 2019 black hole image and a mystery story.
• Discuss "Myth or Fact?" statements and justify opinions with evidence.

Vocabulary List

Grammar Rules

Rule name: Verbs followed by the infinitive (to + base verb) Common verbs: want, need, hope, plan, decide, agree, refuse, offer, promise, seem, appear, tend. Examples: Scientists want to discover more about black holes. / Astronomers hope to capture better images. / The astronaut refused to comment. / The researcher tends to work late.

Rule name: Verbs followed by the gerund (verb + -ing) Common verbs: enjoy, finish, avoid, suggest, practice, consider, imagine, mind, risk. Examples: Scientists finished analyzing the data. / I enjoy reading about space. / I suggest reading more about quantum physics. / Do you mind explaining this theory again? / I can't imagine living on another planet.

Verbs that change meaning:

• remember + infinitive = don't forget a future action (Please remember to set your alarm); remember + gerund = recall a past action (I remember setting my alarm).
• stop + infinitive = pause in order to do something (He stopped to observe the stars); stop + gerund = quit the activity (He stopped observing the stars).
• try + infinitive = make an effort (Try to understand this concept); try + gerund = experiment with a method (Try reading this book).

Verbs taking either form with the same meaning: begin, start, continue, like, love, hate, prefer (I love to study / love studying astronomy).

Active and passive in science reporting: use the passive when the process or result matters more than the doer (A photograph was captured in 2019).

Language Skills & Functions

• Reading - "A Journey to a Black Hole": a black hole is a place where gravity is so strong that not even light can escape, but it is also a mystery and a silent guardian of secrets. At the "event horizon" time slows down and light cannot escape. Writers and filmmakers use black holes as symbols of the unknown (danger for some, opportunity for others). Black holes remind us of two things: that the universe is full of mysteries and that curiosity is the key to understanding them.
• Listening - "Misconception": scientists do not know everything about black holes; light cannot escape them; they may help galaxies stay together; they cannot be seen directly with telescopes; the event horizon is the edge of a black hole. "Myth or Fact?": black holes do not swallow everything - they only pull in things that get very close; if the Sun became a black hole, Earth would stay in orbit. Misconceptions include "black holes can swallow the whole galaxy" and "we can see black holes directly".
• Listening - on science and exploration: science is built on facts, not guesses; many people enjoy imagining black holes as portals; NASA plans new space telescopes; reading about the first moon landing inspired many people.
• Reading - "The Mystery of Black Holes": most black holes form when massive stars at least 20 times heavier than the Sun run out of fuel and collapse under their own gravity in less than a second; the star's mass is compressed into an extremely small point called a singularity. Stellar black holes (from collapsed stars) are the most common; supermassive black holes, millions or billions of times heavier than the Sun, sit at the center of most galaxies, including the Milky Way. Black holes bend space and time (predicted by Einstein over 100 years ago). In 2019 scientists captured the first photograph of a black hole's shadow, proving many theories. They help control how galaxies form and evolve.
• Writing - news report (180-200 words): a journalist reporting on the 2019 image: what was discovered, how it was made, why it matters.
• Mystery story: a short tale about a puzzle or crime to be solved. Steps: 1) think of a mystery (start with a question); 2) create a detective (a student, a robot, even a talking cat) with a name and a special skill; 3) add 2-3 real clues and 1 red herring (a fake clue that confuses the detective); 4) solve the mystery - the answer must make sense and fit the clues. Keep the reader guessing and do not reveal the answer too soon.
• Review 3: revision exercises on vocabulary, language, reading, translation, listening and writing for Units 7-9.

Solved Exercises

Exercise 1. "Scientists refuse ______ guess without evidence." (to guess / guessing) Answer: to guess - refuse + infinitive.

Exercise 2. "The scientist ______ at midnight (quit the activity)." (stopped working / stopped to work) Answer: stopped working - stop + gerund means quit the activity.

Common Mistakes

• Using a gerund after hope, plan, decide, refuse, agree, tend.
• Using the infinitive after enjoy, avoid, suggest, mind, finish, imagine.
• Confusing "remember to do" (not forgetting) with "remember doing" (recalling).
• Confusing "stop to do" (pause in order to) with "stop doing" (quit).
• Thinking black holes "swallow everything" - they only pull in what gets very close.

Quick Revision Checklist

• Infinitive verbs: want, need, hope, plan, decide, agree, refuse, offer, promise, seem, appear, tend.
• Gerund verbs: enjoy, finish, avoid, suggest, practice, consider, imagine, mind, risk.
• remember/stop/try change meaning.
• begin/start/continue/like/love/hate/prefer take either.
• Event horizon = the edge of a black hole.
• Singularity = infinite density point.
• Stellar black holes are the most common.
• Supermassive black holes sit at the center of galaxies.
• 2019 = first photograph of a black hole's shadow.
• Mystery story = mystery + detective + clues + red herring + solution.
