Bài 1: Đọc đoạn văn sau và trả lời câu hỏi: “ Bởi tôi ăn uống điều độ và làm việc có chừng mực nên tôi chóng lớn lắm. Chẳng bao lâu tôi đã trở thành chàng dế thanh niên cường tráng. Đôi càng tôi mẫm bóng. Những cái vuốt ở chân, ở khoeo cứ cứng dần và nhọn hoắt. Thỉnh thoảng, muốn thử sự lợi hại của những chiếc vuốt, tôi co cẳng lên, đạp phanh phách vào các ngọn cỏ. Những ngọn cỏ gãy rạp, y như có nhát dao vừa lia qua. Đôi cánh tôi trước kia ngắn hủn hoẳn, bây giờ thành cái áo dài kín xuống tận chấm đuôi. Mỗi khi tôi vũ lên, đã nghe tiếng phành phạch giòn giã. Lúc tôi đi bách bộ thì cả người tổi rung rinh một màu nâu bóng mỡ soi gương được và rất ưa nhìn. Đầu tôi to ra và nổi từng tảng, rất bướng. Hai cái răng đen nhánh lúc nào cũng nhai ngoàm ngoặm như hai lưỡi liềm máy làm việc. Sợi râu tôi dài và uốn cong một vẻ rất đỗi hùng dũng. c.
