Bobby had tried to climb to the top of the snowy mountain for at least thirty times. But he had always ______. At first, he climbed very well, but as he went on, he became weak and often looked at his worn-out shoes ______ looking up. Finally, when the clouds gathered around him, he understood he wouldn’t be able to ______ the top that day. He would sit down to rest and then ______.
One day, he went up the mountain ______ by old Peeper, the town optician (配镜师). Halfway to the top, Peeper gave him a pair of ______ sunglasses. “If it starts clouding over, put these glasses on. They’ll ______ you,” said Peeper before he went back. Bobby accepted the ______.
Just as nearly always seemed to happen, bad luck ______ in the form of cloud cover. Bobby remembered Peeper’s ______ and put on the glasses. He could ______ see the clouds with the glasses on, but they seemed so light that he could see the top of the mountain ______ the clouds. And so Bobby kept climbing, leaving the clouds behind, and ______ arrived at the top of the mountain. He felt great. But as he took off the glasses, he was ______ — the mountain below was surrounded by a sea of clouds. Bobby didn’t remember the clouds being as ______ as that, so he looked more closely at the sunglasses, and ______ everything.
Peeper had made a light picture on the glasses, in the ______ of the snow-covered mountain top. It was made in such a way that Bobby could only ______ it if he looked upwards.
