Reading Passage: The Amazing Monarch Butterfly / La Asombrosa Mariposa Monarca 3 Chunks / 3 Fragmentos
P1 [Intro] Monarch butterflies are among the most remarkable insects on Earth, but they face dangerous threats that require urgent human protection.
P2 [Body 1] Every autumn, millions of monarchs fly up to 3,000 miles from Canada to the warm mountain forests of Mexico. They navigate using the sun and Earth’s magnetic field. This long migration is one of nature's greatest wonders.
P3 [Body 2] Sadly, monarch populations have dropped because their milkweed food plants are being destroyed by chemicals, and logging harms their winter forests. To save them, students and scientists across North America are planting native milkweed gardens.

Text: The Superpowers of Honeybees / Los Superpoderes de las Abejas Science Informational
P1 Honeybees are famous for making sweet honey, but their greatest role is helping crops reproduce. When worker bees visit flowers to gather sweet nectar, yellow pollen grains stick to their fuzzy legs.
P2 As bees fly to other blossoms, they pollinate the plants by transferring pollen, which causes fruits, nuts, and vegetables to grow. Without bee pollination, one-third of the human food supply would vanish.
P3 Inside the hive, bees communicate using a special "waggle dance." By wiggling their bodies in figure-eight patterns, bees tell hive-mates the exact direction and distance of rich flower fields.

P1 [Intro] Scientists long believed that living creatures could not survive in the sunless, freezing deep ocean, but hydrothermal vents prove that life can flourish in Earth's most hostile environments.
P2 [Section 1: Black Smokers] Underwater volcanic vents spew mineral water boiling at 700°F into the freezing sea. Even without sunlight, special bacteria convert toxic sulfur chemicals directly into food, providing the energy foundation for the entire food chain.
P3 [Section 2: Alien Oasis] Around these vents, giant six-foot red tube worms, blind shrimp, and white crabs form a thriving ecosystem. These deep-sea creatures survive without plants or sun because the bacteria nourish them.
