One summer night, Tina and her brother Tom were camping in their backyard. They lay on the grass, staring at the stars. Suddenly, a bright green light flashed across the sky. “Did you see that ” Tom asked 1 excitement. Tina nodded, her eyes wide. “It’s moving toward the forest!”
The next morning, they packed a bag with snacks, a flashlight, and a notebook 2 they wanted to record everything. As they entered the forest, the air felt colder. They followed a narrow path until they found a clearing. In the center was a large metallic object, half-buried in the ground. “This looks like a spaceship!” Tom whispered.
Suddenly, they heard a low hum. Two tall figures with glowing blue eyes stepped out from behind the trees. Tina 3 Tom’s hand tightly. The creatures made soft clicking sounds. One held out a device that projected holographic images of planets. “They’re showing us their home!” Tina said 4 .
The aliens led them inside the spaceship. The walls were covered in symbols, and a screen displayed maps of galaxies. “They must 5 traveled thousands of light-years,” Tom said. Before leaving, the aliens gave them a small crystal. “This is 6 symbol of peace,” one alien said in a robotic voice.
When they returned home, their parents laughed. “ 7 no one believes you, we do,” their mom said. Tina placed the crystal under her pillow. Every night, it glowed softly, reminding them of their adventure.

Later, they wondered 11 the aliens would return. They spent hours researching online but found 12 useful information. One day, Tina noticed a strange pattern in the crystal’s glow. “Maybe it’s a message!” she said 13 .
Tom suggested 14 the crystal to a scientist. However, Tina refused. “It’s our secret,” she said firmly. 15 , they kept the crystal hidden, hoping to solve its mystery themselves.

第三大题 阅读理解（共 15 小题；每小题 2 分，满分 30 分）
阅读下列短文，从每题所给的 A、B、C 和 D 项中选出最佳选项，并在答题卡上将该项涂黑。
Science fiction has long been a window into humanity’s imagination of extraterrestrial life. One of the most iconic depictions appears in H.G. Wells’ The War of the Worlds, where Martians invade Earth with advanced machinery, including heat-rays and towering tripods. Unlike friendly aliens in later works, these creatures are portrayed as hostile, driven by a need to conquer the planet for resources. This portrayal reflects the fears of colonialism and technological dominance prevalent in the late 19th century.
In contrast, Steven Spielberg’s E.T. the Extra-Terrestrial presents aliens as gentle beings seeking friendship. The story of a lost alien befriending a human child became a symbol of hope, showing that extraterrestrial life might share our capacity for empathy. This shift in narrative reflects changing cultural attitudes toward “the unknown,” from fear to curiosity.
Modern science fiction often explores more complex themes. In Arrival, aliens visit Earth not to conquer but to share their language, challenging humans to rethink communication and time. Such stories ask: If we encounter intelligent aliens, will our differences divide us, or can we collaborate
As real-world scientists search for signs of life beyond Earth, these fictional tales remind us of the power of imagination. They inspire curiosity while prompting us to reflect on humanity’s place in the universe.
26. What do the Martians in The War of the Worlds use to attack Earth
A. Heat-rays and tripods
B. Poisonous gas and spaceships
C. Mind control and lasers
D. Advanced computers and robots
27. How does E.T. the Extra-Terrestrial differ from older alien stories
A. It shows aliens as technological invaders
B. It portrays aliens as peaceful friends
C. It focuses on alien languages
D. It avoids talking about alien appearances
28. What theme does Arrival explore
A. The fear of the unknown
B. The power of technology
C. Communication between species
D. The danger of alien invasion
29. What is the main idea of the passage
A. Aliens in science fiction reflect human culture and fears
B. All alien stories are about invasion and conflict
C. Real-life science influences how aliens are portrayed
D. Science fiction discourages the search for extraterrestrial life
The 1947 Roswell Incident remains one of the most debated UFO cases. When a farmer found unusual metal debris on his ranch, the U.S. military initially claimed it was a “flying saucer,” only to later retract the statement, calling it a weather balloon. This contradiction sparked decades of rumors about a government cover-up of alien technology.
Skeptics argue that most UFO sightings have logical explanations. For example, the “Phoenix Lights” in 1997 were later identified as military flares, while 球状闪电 (ball lightning) often causes misinterpretations of glowing objects in the sky. Psychological factors also play a role—people may perceive patterns or anomalies due to confirmation bias.
However, some cases defy easy explanation. The U.S. Pentagon’s 2021 report on Unidentified Aerial Phenomena (UAPs) acknowledged that some sightings show objects moving at high speeds without visible propulsion, challenging current technological understanding. While these do not prove aliens, they highlight the need for scientific inquiry.
Astrophysicist Neil deGrasse Tyson notes, “The universe is too vast for us to be alone.” Yet, until concrete evidence emerges, the line between science and speculation remains blurred.
30. Why did the Roswell Incident become famous
A. The military confirmed it was an alien spaceship
B. The debris was proven to be from Mars
C. The military’s changing statements sparked rumors
D. A farmer took clear photos of aliens
31. What caused the “Phoenix Lights” misunderstanding
A. Ball lightning
B. Military flares
C. Alien spacecraft
D. Weather balloons
32. What does the Pentagon’s report suggest about UAPs
A. They are definitely alien ships
B. They have no scientific explanation yet
C. They are all misinterpretations
D. They pose a threat to Earth
33. What is the author’s attitude toward UFOs
A. They are all hoaxes
B. They should be ignored
C. They deserve scientific study
D. They prove alien existence
Scientists use the “Goldilocks Zone” to identify planets where life might thrive. This is the narrow area around a star where temperatures allow liquid water—essential for life as we know it. Mars, located on the edge of the Sun’s Goldilocks Zone, has fascinated scientists for decades. The Mars rover Perseverance has been searching for signs of ancient microbial life, drilling into rock formations to collect samples.
Beyond our solar system, Jupiter’s moon Europa and Saturn’s moon Enceladus are promising targets. Both have subsurface oceans heated by tidal forces, potentially harboring conditions suitable for life. In 2024, the Europa Clipper mission will study Europa’s icy crust, looking for clues of life beneath.
The Drake Equation, developed by astronomer Frank Drake, estimates the number of intelligent civilizations in the Milky Way. By multiplying factors like star formation rate and the probability of life evolving intelligence, it suggests that even a low chance could mean thousands of civilizations in a galaxy with billions of stars.
While we haven’t found extraterrestrial life yet, each discovery—from exoplanets to organic molecules in space—brings us closer to answering the age-old question: Are we alone
34. What is the Goldilocks Zone
A. A region on Mars with water
B. An area around stars with suitable temperatures
C. A zone for spaceship landing
D. A term for alien civilizations
35. Why are Europa and Enceladus studied for life
A. They have thick atmospheres
B. They have active volcanoes
C. They have underground oceans
D. They are near the Sun
36. What does the Drake Equation aim to calculate
A. The distance to the nearest star
B. The number of alien civilizations
C. The age of the universe
D. The probability of alien
37. What is the best title for this passage
A. The Search for Life Beyond Earth
B. Mars: The Only Habitable Planet
C. The Mystery of the Goldilocks Zone
D. Why We Haven’t Found Aliens Yet
Tina woke up at midnight to see a yellow light dive toward the forest. The next day, she and her brother Tom explored and found a damaged spaceship with two aliens. “It had a round head and a silver body,” Tina described. But their father refused to believe them. “No one else saw these aliens,” he said.
The twist In the story’s final scene, Tina and Tom “spread their wings and flew to school,” hinting they might be from a world where humans have wings. This unexpected ending blurs the line between “aliens” and the children’s own identity, making readers question: Who is the real “alien” here
The story uses vivid descriptions to build tension, such as the aliens’ “strange language” and the damaged spaceship. It also teaches grammatical structures like adverbial clauses of reason (“I heard a loud noise, so we explored the forest”) and “because of” (“The spaceship crashed because of a technical error”).
As a teaching tool, it encourages students to discuss belief, curiosity, and the unknown—key themes of Module 4’s “Discovery” unit.
38. Why did Tina and Tom go to the forest
A. They saw aliens there
B. They heard a loud noise
C. Their father asked them to
D. They wanted to fly
39. What did the alien look like
A. Tall with a round head and silver body
B. Short with feathers and a red nose
C. Invisible but made strange noises
D. Like a human with wings
40. What is the surprise ending of the story
A. The aliens were friendly
B. The father saw the spaceship too
C. Tina and Tom are not human
D. The spaceship repaired itself
