Introduction

Jared Isaacman is the leader of NASA. He says Pluto should be a planet again.

Main Body

In 2006, a group of scientists said Pluto is not a planet. They said it is too small. They called it a dwarf planet. In 2015, NASA sent a ship to Pluto. The ship took photos. The photos show that Pluto has ice and mountains. It is a very active place. Now, NASA is writing new papers. They want to show that Pluto is a real planet. They also want to remember Clyde Tombaugh. He found Pluto in 1930.

Conclusion

Pluto is still a dwarf planet now. But NASA wants to change this.

🚀 The 'Time Jump' Pattern

Look at how the story moves from the past to now. This is the secret to reaching A2: mixing Past and Present.

1. The Past (Finished Actions) When we talk about 2006 or 1930, we use a special ending: -ed.

  • Said (Past of say) → "They said it is too small."
  • Called (Past of call) → "They called it a dwarf planet."
  • Found (Past of find) → "He found Pluto."

2. The Present (Current Facts) When we talk about today, we use the simple form.

  • Is → "Pluto is still a dwarf planet."
  • Wants → "NASA wants to change this."

Quick Guide for You:

  • Yesterday/Past Year →\rightarrow -ed (or irregular like found)
  • Today/Now →\rightarrow Simple form (is/wants/has)

Key Word Bridge: Now →\rightarrow This word tells the reader: "Stop using the past, start using the present!"
