"He pointed his finger at the thief and shouted, 'That's the man who stole my wallet!'"（他用手指指着小偷大喊：“就是那个偷了我钱包的人！”）
"She gestured to the left, indicating that we should turn that way."（她向左指了指，表明我们应该那边转弯。）
"The statue on the right is called 'Dexter,' while the one on the left is called 'Sinister.'"（右边的雕像叫做“Dexter”，而左边的叫做“Sinister”。）
