4.功能需求:

1. 題庫有 n 題，隨機出其中的 10 題，每次玩的時候題目順序都不一樣。

2. 畫面上顯示目前題目是第幾題

3. 玩完後可選擇再玩一次，重新開始玩。

5.加分功能:

1. 利用 AVSpeechSynthesizer 唸出題目和答案。

class SyntesizerModel: NSObject,ObservableObject,AVSpeechSynthesizerDelegate {
    @Published var isSpeaking = false
    @Published var isPaused = false
    private var synthesizer = AVSpeechSynthesizer()
        override init() {
            super.init()
            synthesizer.delegate = self
        }
    
    func speak(_ utterance: AVSpeechUtterance) {
        
            if !isSpeaking && !isPaused{
                self.synthesizer.speak(utterance)
            }
            else if isSpeaking && !isPaused {
                self.synthesizer.pauseSpeaking(at: AVSpeechBoundary.immediate)
            }
            else if isPaused && !isSpeaking{
                self.synthesizer.continueSpeaking()
            }
        }

    }()
func playFromStart() {
        seek(to: .zero)
        play()
    }
}

2. 做成選擇題版本，判斷是否答對和計分。
