Dave and his younger sister Tina lived in a small village. One day, they took part in a competition. They had to climb a few 1to win the competition.
In the beginning, things went 2. But after a few days. Dave was too tired to walk any farther. Tina was 3 him. In Tina's eyes. Dave could do everything well.
"Perhaps I should be the strong one and 4 him." she thought. So she said to Dave, "All right, but you should walk 5 me for the rest of the day. Then you can go back if you like" This was easy for Dave, 6 he agreed and they achieved their goal. The next day, Tina pointed to the next mountain and said. "I 7 you to walk to that mountain with me."
Dave agreed 8 because it was not far. Every day, Tina would set an easy goal for Dave so that he could walk with her. Finally. 9 finished climbing all the mountains and won the competition.
All of us face challenges (挑战). But if we 10 them step by step (逐步地), we will succeed in the end.
