Tưởng chừng như năm tháng ròng rã qua đi, thời gian chỉ trôi chầm chậm. Nhưng đến khi ta đi đến quá một nửa con đường, mới thấy thời gian đang lặng lẽ trôi nhanh. Mới ngày nào còn nghe ấm áp bên tai câu hát ru “à ơi” của mẹ, mới ngày nào còn được bố dắt tay tập đi,mà giờ đây chúng ta đã dần khôn lớn, dần trưởng thành cả rồi. Tuổi thơ mỗi người một khác. Có người gắn liền với cánh diều ngoài đê, với cảnh xế chiều lại dắt con trâu nhà ăn cỏ ngoài đồng về. Có người lại gắn bó với nhịp sống ồn ào của thành thị, tiếng cười đùa của tất cả trẻ con dãy phố. Tuổi thơ tôi cũng vậy. Tuổi thơ của tôi bắt đầu từ những câu hát ru ngọt ngào của mẹ và giọt mồ hôi nóng hổi trên vai bố. Thời gian trôi đi mau làm đôi chân tôi vững vàng hơn, và miệng có thể thốt lên từ “cha”, “mẹ”. Lên ba, tôi được mẹ cho đến học ở trường mẫu giáo. Mỗi sáng, ông tôi thường dắt tôi đến trường. Ông kể, tôi đi học ngoan lắm, chẳng khóc bao giờ, cô giáo cũng phải khen. Suốt ba năm trời gắn bó với trường mẫu giáo, chẳng mấy chốc đã đến lúc phải chia xa.Rồi mùa thu năm ấy, mẹ tôi đưa tôi đi dự ngày khai giảng đầu tiên, ngày tôi chính thức là học sinh lớp một, đã chính thức tiến những bước đầu trong con đường học tập của mình và bước vào một chuỗi ngày tháng mang tên “Tuổi học trò”. Những tháng ngày ở mái trường tiểu học của tôi trôi qua nhanh lắm. Cây phượng cuối sân trường đã qua năm mùa hoa, tiếng trống trường quen thuộc, tôi đã sắp phải nghe những hồi cuối cùng. Rồi mùa hè cuối cùng cũng đến, nắng vàng lại tràn ngập trên tất cả mọi vật, làm nổi bật một màu đỏ tươi của chiếc khăn quàng trên nên áo trắng. Lại thêm một cuộc chia, nhưng đó cũng cũng là một khởi đầu, với một con đường mới, bước vào mái trường trung học cơ sở. Mới lúc đầu bước vào nơi này còn bao bỡ ngỡ, vậy mà rồi cái gì cũng trở nên quen thuộc. Mỗi giờ học, mỗi học kì hay một năm học đều gắn liền với những kỉ niệm vui buồn khác nhau. Những gương mặt thầy cô, bạn bè rồi cũng trở nên thật thân quen, gần gũi. Một năm học trôi qua, tôi lại càng thấy yêu ngôi trường này hơn nữa. Giờ đã là học sinh lớp 7, đã trưởng thành, khôn lớn hơn, ngay lúc này đây, tôi vẫn đang cố gắng học tập rèn luyện hơn nữa. Tôi càng không ngừng mong mỏi ngày mai sẽ đến nhanh, sẽ được gặp thầy cô bè bạn nhiều hơn, được học tập dưới mái trường này nhiều hơn thì lại thêm lo sợ rằng, một “ngày mai” nào đó, tôi sẽ phải nhận ra rằng mình không còn là một học sinh trung học cơ sở. Con đường dài mang tên “tuổi thơ” còn chờ đợi chúng ta bước tiếp. Thế nhưng khi đến cuổi con đường ấy, khi quay đầu nhìn lại, hay nghĩ xem ta đã làm và làm được những gì. Hãy tiếp gắng và quyết vươn tới những điều mình mong muốn, hãy tiếp tục học hành để làm hài lòng thầy cô cha mẹ. Nếu chúng ta làm được những điều đó, thì hãy nghĩ mà xem. Tuổi thơ của ta sẽ trở nên ý nghĩa biết bao.</span></a></p><a class="font-xs card-text text-dark"

Tưởng chừng như năm tháng ròng rã qua đi, thời gian chỉ trôi chầm chậm. Nhưng đến khi ta đi đến quá một nửa con đường, mới thấy thời gian đang lặng lẽ trôi nhanh. Mới ngày nào còn nghe ấm áp bên tai câu hát ru “à ơi” của mẹ, mới ngày nào còn được bố dắt tay tập đi,mà giờ đây chúng ta đã dần khôn lớn, dần trưởng thành cả rồi. Tuổi thơ mỗi người một khác. Có người gắn liền với cánh diều ngoài đê, với cảnh xế chiều lại dắt con trâu nhà ăn cỏ ngoài đồng về. Có người lại gắn bó với nhịp sống ồn ào của thành thị, tiếng cười đùa của tất cả trẻ con dãy phố. Tuổi thơ tôi cũng vậy. Tuổi thơ của tôi bắt đầu từ những câu hát ru ngọt ngào của mẹ và giọt mồ hôi nóng hổi trên vai bố. Thời gian trôi đi mau làm đôi chân tôi vững vàng hơn, và miệng có thể thốt lên từ “cha”, “mẹ”. Lên ba, tôi được mẹ cho đến học ở trường mẫu giáo. Mỗi sáng, ông tôi thường dắt tôi đến trường. Ông kể, tôi đi học ngoan lắm, chẳng khóc bao giờ, cô giáo cũng phải khen. Suốt ba năm trời gắn bó với trường mẫu giáo, chẳng mấy chốc đã đến lúc phải chia xa.Rồi mùa thu năm ấy, mẹ tôi đưa tôi đi dự ngày khai giảng đầu tiên, ngày tôi chính thức là học sinh lớp một, đã chính thức tiến những bước đầu trong con đường học tập của mình và bước vào một chuỗi ngày tháng mang tên “Tuổi học trò”. Những tháng ngày ở mái trường tiểu học của tôi trôi qua nhanh lắm. Cây phượng cuối sân trường đã qua năm mùa hoa, tiếng trống trường quen thuộc, tôi đã sắp phải nghe những hồi cuối cùng. Rồi mùa hè cuối cùng cũng đến, nắng vàng lại tràn ngập trên tất cả mọi vật, làm nổi bật một màu đỏ tươi của chiếc khăn quàng trên nên áo trắng. Lại thêm một cuộc chia, nhưng đó cũng cũng là một khởi đầu, với một con đường mới, bước vào mái trường trung học cơ sở. Mới lúc đầu bước vào nơi này còn bao bỡ ngỡ, vậy mà rồi cái gì cũng trở nên quen thuộc. Mỗi giờ học, mỗi học kì hay một năm học đều gắn liền với những kỉ niệm vui buồn khác nhau. Những gương mặt thầy cô, bạn bè rồi cũng trở nên thật thân quen, gần gũi. Một năm học trôi qua, tôi lại càng thấy yêu ngôi trường này hơn nữa. Giờ đã là học sinh lớp 7, đã trưởng thành, khôn lớn hơn, ngay lúc này đây, tôi vẫn đang cố gắng học tập rèn luyện hơn nữa. Tôi càng không ngừng mong mỏi ngày mai sẽ đến nhanh, sẽ được gặp thầy cô bè bạn nhiều hơn, được học tập dưới mái trường này nhiều hơn thì lại thêm lo sợ rằng, một “ngày mai” nào đó, tôi sẽ phải nhận ra rằng mình không còn là một học sinh trung học cơ sở. Con đường dài mang tên “tuổi thơ” còn chờ đợi chúng ta bước tiếp. Thế nhưng khi đến cuổi con đường ấy, khi quay đầu nhìn lại, hay nghĩ xem ta đã làm và làm được những gì. Hãy tiếp gắng và quyết vươn tới những điều mình mong muốn, hãy tiếp tục học hành để làm hài lòng thầy cô cha mẹ. Nếu chúng ta làm được những điều đó, thì hãy nghĩ mà xem. Tuổi thơ của ta sẽ trở nên ý nghĩa biết bao.</span></a></p><a class="font-xs card-text text-dark"

Tưởng chừng như năm tháng ròng rã qua đi, thời gian chỉ trôi chầm chậm. Nhưng đến khi ta đi đến quá một nửa con đường, mới thấy thời gian đang lặng lẽ trôi nhanh. Mới ngày nào còn nghe ấm áp bên tai câu hát ru “à ơi” của mẹ, mới ngày nào còn được bố dắt tay tập đi,mà giờ đây chúng ta đã dần khôn lớn, dần trưởng thành cả rồi. Tuổi thơ mỗi người một khác. Có người gắn liền với cánh diều ngoài đê, với cảnh xế chiều lại dắt con trâu nhà ăn cỏ ngoài đồng về. Có người lại gắn bó với nhịp sống ồn ào của thành thị, tiếng cười đùa của tất cả trẻ con dãy phố. Tuổi thơ tôi cũng vậy. Tuổi thơ của tôi bắt đầu từ những câu hát ru ngọt ngào của mẹ và giọt mồ hôi nóng hổi trên vai bố. Thời gian trôi đi mau làm đôi chân tôi vững vàng hơn, và miệng có thể thốt lên từ “cha”, “mẹ”. Lên ba, tôi được mẹ cho đến học ở trường mẫu giáo. Mỗi sáng, ông tôi thường dắt tôi đến trường. Ông kể, tôi đi học ngoan lắm, chẳng khóc bao giờ, cô giáo cũng phải khen. Suốt ba năm trời gắn bó với trường mẫu giáo, chẳng mấy chốc đã đến lúc phải chia xa.Rồi mùa thu năm ấy, mẹ tôi đưa tôi đi dự ngày khai giảng đầu tiên, ngày tôi chính thức là học sinh lớp một, đã chính thức tiến những bước đầu trong con đường học tập của mình và bước vào một chuỗi ngày tháng mang tên “Tuổi học trò”. Những tháng ngày ở mái trường tiểu học của tôi trôi qua nhanh lắm. Cây phượng cuối sân trường đã qua năm mùa hoa, tiếng trống trường quen thuộc, tôi đã sắp phải nghe những hồi cuối cùng. Rồi mùa hè cuối cùng cũng đến, nắng vàng lại tràn ngập trên tất cả mọi vật, làm nổi bật một màu đỏ tươi của chiếc khăn quàng trên nên áo trắng. Lại thêm một cuộc chia, nhưng đó cũng cũng là một khởi đầu, với một con đường mới, bước vào mái trường trung học cơ sở. Mới lúc đầu bước vào nơi này còn bao bỡ ngỡ, vậy mà rồi cái gì cũng trở nên quen thuộc. Mỗi giờ học, mỗi học kì hay một năm học đều gắn liền với những kỉ niệm vui buồn khác nhau. Những gương mặt thầy cô, bạn bè rồi cũng trở nên thật thân quen, gần gũi. Một năm học trôi qua, tôi lại càng thấy yêu ngôi trường này hơn nữa. Giờ đã là học sinh lớp 7, đã trưởng thành, khôn lớn hơn, ngay lúc này đây, tôi vẫn đang cố gắng học tập rèn luyện hơn nữa. Tôi càng không ngừng mong mỏi ngày mai sẽ đến nhanh, sẽ được gặp thầy cô bè bạn nhiều hơn, được học tập dưới mái trường này nhiều hơn thì lại thêm lo sợ rằng, một “ngày mai” nào đó, tôi sẽ phải nhận ra rằng mình không còn là một học sinh trung học cơ sở. Con đường dài mang tên “tuổi thơ” còn chờ đợi chúng ta bước tiếp. Thế nhưng khi đến cuổi con đường ấy, khi quay đầu nhìn lại, hay nghĩ xem ta đã làm và làm được những gì. Hãy tiếp gắng và quyết vươn tới những điều mình mong muốn, hãy tiếp tục học hành để làm hài lòng thầy cô cha mẹ. Nếu chúng ta làm được những điều đó, thì hãy nghĩ mà xem. Tuổi thơ của ta sẽ trở nên ý nghĩa biết bao.</span></a></p><a class="font-xs card-text text-dark"

Cô là hiện thân của sức mạnh phi thường, ý chí kiên cường và lòng trung thành tuyệt đối, để lại ấn tượng sâu đậm trong lòng người hâm mộ.</span></span><span> <span>Về ngoại hình, Mikasa mang một vẻ đẹp sắc sảo, lạnh lùng nhưng cũng đầy cuốn hút. Cô sở hữu vóc dáng cân đối, khỏe khoắn. Điểm nhấn trên khuôn mặt là mái tóc đen ngắn gọn gàng (dù từng để tóc dài), đôi mắt xám sắc lạnh và làn da trắng tái. Đặc biệt, hình ảnh Mikasa luôn gắn liền với chiếc khăn quàng cổ màu đỏ thẫm – món quà và lời thề gắn kết định mệnh với Eren Yeager. Chiếc khăn ấy không chỉ là vật giữ ấm mà còn là biểu tượng của sự che chở, tình yêu và lòng dũng cảm.</span></span><span> <span> <span>Là hậu duệ của gia tộc Ackerman, cô mang trong mình sức mạnh chiến đấu vượt trội, được ví như một người cân cả trăm chiến binh. Dù là đối diện với bầy Titan hung tợn hay những kẻ thù tàn độc nhất, những đường kiếm cơ động của Mikasa đều vô cùng dứt khoát, uyển chuyển nhưng chết chóc. Trong các trận chiến, cô luôn là chỗ dựa vững chắc, sẵn sàng xả thân để bảo vệ những người mình yêu thương, đặc biệt là Eren.</span></span></span><span> <span> <span>Đằng sau vẻ ngoài gai góc và lạnh lùng đó là một tâm hồn vô cùng nhạy cảm và chất chứa nhiều nỗi đau. Tuổi thơ bi thảm khi chứng kiến cha mẹ bị sát hại đã suýt cướp đi mạng sống của Mikasa. Chính sự ấm áp và chiếc khăn quàng từ Eren đã kéo cô trở lại cuộc sống, biến anh trở thành lý do để cô tiếp tục tồn tại và chiến đấu. Tình yêu của Mikasa dành cho Eren thuần khiết, vị tha nhưng cũng đầy bi kịch. Cô đã phải đưa ra lựa chọn đau đớn nhất đời mình để ngăn chặn sự hủy diệt của nhân loại, nhưng cũng chính quyết định đó đã giải thoát cho cả thế giới và chính linh hồn của Eren.</span></span></span><span> <span> <span>Mặc dù có một kết cục đẫm nước mắt, Mikasa vẫn vươn lên mạnh mẽ, tự tìm thấy hạnh phúc mới và sống một cuộc đời trọn vẹn. Cô là minh chứng tuyệt đẹp cho một nữ cường nhân – người phụ nữ không chỉ mạnh mẽ trên chiến trường mà còn kiên cường trong tình yêu và định mệnh. Hình tượng Mikasa sẽ mãi là một vì sao sáng, biểu tượng của lòng dũng cảm và sự tận hiến trong thế giới giả tưởng.</span></span></span></a></div><a class="font-xs card-text text-dark"

Tưởng chừng như năm tháng ròng rã qua đi, thời gian chỉ trôi chầm chậm. Nhưng đến khi ta đi đến quá một nửa con đường, mới thấy thời gian đang lặng lẽ trôi nhanh. Mới ngày nào còn nghe ấm áp bên tai câu hát ru “à ơi” của mẹ, mới ngày nào còn được bố dắt tay tập đi,mà giờ đây chúng ta đã dần khôn lớn, dần trưởng thành cả rồi. Tuổi thơ mỗi người một khác. Có người gắn liền với cánh diều ngoài đê, với cảnh xế chiều lại dắt con trâu nhà ăn cỏ ngoài đồng về. Có người lại gắn bó với nhịp sống ồn ào của thành thị, tiếng cười đùa của tất cả trẻ con dãy phố. Tuổi thơ tôi cũng vậy. Tuổi thơ của tôi bắt đầu từ những câu hát ru ngọt ngào của mẹ và giọt mồ hôi nóng hổi trên vai bố. Thời gian trôi đi mau làm đôi chân tôi vững vàng hơn, và miệng có thể thốt lên từ “cha”, “mẹ”. Lên ba, tôi được mẹ cho đến học ở trường mẫu giáo. Mỗi sáng, ông tôi thường dắt tôi đến trường. Ông kể, tôi đi học ngoan lắm, chẳng khóc bao giờ, cô giáo cũng phải khen. Suốt ba năm trời gắn bó với trường mẫu giáo, chẳng mấy chốc đã đến lúc phải chia xa.Rồi mùa thu năm ấy, mẹ tôi đưa tôi đi dự ngày khai giảng đầu tiên, ngày tôi chính thức là học sinh lớp một, đã chính thức tiến những bước đầu trong con đường học tập của mình và bước vào một chuỗi ngày tháng mang tên “Tuổi học trò”. Những tháng ngày ở mái trường tiểu học của tôi trôi qua nhanh lắm. Cây phượng cuối sân trường đã qua năm mùa hoa, tiếng trống trường quen thuộc, tôi đã sắp phải nghe những hồi cuối cùng. Rồi mùa hè cuối cùng cũng đến, nắng vàng lại tràn ngập trên tất cả mọi vật, làm nổi bật một màu đỏ tươi của chiếc khăn quàng trên nên áo trắng. Lại thêm một cuộc chia, nhưng đó cũng cũng là một khởi đầu, với một con đường mới, bước vào mái trường trung học cơ sở. Mới lúc đầu bước vào nơi này còn bao bỡ ngỡ, vậy mà rồi cái gì cũng trở nên quen thuộc. Mỗi giờ học, mỗi học kì hay một năm học đều gắn liền với những kỉ niệm vui buồn khác nhau. Những gương mặt thầy cô, bạn bè rồi cũng trở nên thật thân quen, gần gũi. Một năm học trôi qua, tôi lại càng thấy yêu ngôi trường này hơn nữa. Giờ đã là học sinh lớp 7, đã trưởng thành, khôn lớn hơn, ngay lúc này đây, tôi vẫn đang cố gắng học tập rèn luyện hơn nữa. Tôi càng không ngừng mong mỏi ngày mai sẽ đến nhanh, sẽ được gặp thầy cô bè bạn nhiều hơn, được học tập dưới mái trường này nhiều hơn thì lại thêm lo sợ rằng, một “ngày mai” nào đó, tôi sẽ phải nhận ra rằng mình không còn là một học sinh trung học cơ sở. Con đường dài mang tên “tuổi thơ” còn chờ đợi chúng ta bước tiếp. Thế nhưng khi đến cuổi con đường ấy, khi quay đầu nhìn lại, hay nghĩ xem ta đã làm và làm được những gì. Hãy tiếp gắng và quyết vươn tới những điều mình mong muốn, hãy tiếp tục học hành để làm hài lòng thầy cô cha mẹ. Nếu chúng ta làm được những điều đó, thì hãy nghĩ mà xem. Tuổi thơ của ta sẽ trở nên ý nghĩa biết bao.</span></a></p><a class="font-xs card-text text-dark"

Tưởng chừng như năm tháng ròng rã qua đi, thời gian chỉ trôi chầm chậm. Nhưng đến khi ta đi đến quá một nửa con đường, mới thấy thời gian đang lặng lẽ trôi nhanh. Mới ngày nào còn nghe ấm áp bên tai câu hát ru “à ơi” của mẹ, mới ngày nào còn được bố dắt tay tập đi,mà giờ đây chúng ta đã dần khôn lớn, dần trưởng thành cả rồi. Tuổi thơ mỗi người một khác. Có người gắn liền với cánh diều ngoài đê, với cảnh xế chiều lại dắt con trâu nhà ăn cỏ ngoài đồng về. Có người lại gắn bó với nhịp sống ồn ào của thành thị, tiếng cười đùa của tất cả trẻ con dãy phố. Tuổi thơ tôi cũng vậy. Tuổi thơ của tôi bắt đầu từ những câu hát ru ngọt ngào của mẹ và giọt mồ hôi nóng hổi trên vai bố. Thời gian trôi đi mau làm đôi chân tôi vững vàng hơn, và miệng có thể thốt lên từ “cha”, “mẹ”. Lên ba, tôi được mẹ cho đến học ở trường mẫu giáo. Mỗi sáng, ông tôi thường dắt tôi đến trường. Ông kể, tôi đi học ngoan lắm, chẳng khóc bao giờ, cô giáo cũng phải khen. Suốt ba năm trời gắn bó với trường mẫu giáo, chẳng mấy chốc đã đến lúc phải chia xa.Rồi mùa thu năm ấy, mẹ tôi đưa tôi đi dự ngày khai giảng đầu tiên, ngày tôi chính thức là học sinh lớp một, đã chính thức tiến những bước đầu trong con đường học tập của mình và bước vào một chuỗi ngày tháng mang tên “Tuổi học trò”. Những tháng ngày ở mái trường tiểu học của tôi trôi qua nhanh lắm. Cây phượng cuối sân trường đã qua năm mùa hoa, tiếng trống trường quen thuộc, tôi đã sắp phải nghe những hồi cuối cùng. Rồi mùa hè cuối cùng cũng đến, nắng vàng lại tràn ngập trên tất cả mọi vật, làm nổi bật một màu đỏ tươi của chiếc khăn quàng trên nên áo trắng. Lại thêm một cuộc chia, nhưng đó cũng cũng là một khởi đầu, với một con đường mới, bước vào mái trường trung học cơ sở. Mới lúc đầu bước vào nơi này còn bao bỡ ngỡ, vậy mà rồi cái gì cũng trở nên quen thuộc. Mỗi giờ học, mỗi học kì hay một năm học đều gắn liền với những kỉ niệm vui buồn khác nhau. Những gương mặt thầy cô, bạn bè rồi cũng trở nên thật thân quen, gần gũi. Một năm học trôi qua, tôi lại càng thấy yêu ngôi trường này hơn nữa. Giờ đã là học sinh lớp 7, đã trưởng thành, khôn lớn hơn, ngay lúc này đây, tôi vẫn đang cố gắng học tập rèn luyện hơn nữa. Tôi càng không ngừng mong mỏi ngày mai sẽ đến nhanh, sẽ được gặp thầy cô bè bạn nhiều hơn, được học tập dưới mái trường này nhiều hơn thì lại thêm lo sợ rằng, một “ngày mai” nào đó, tôi sẽ phải nhận ra rằng mình không còn là một học sinh trung học cơ sở. Con đường dài mang tên “tuổi thơ” còn chờ đợi chúng ta bước tiếp. Thế nhưng khi đến cuổi con đường ấy, khi quay đầu nhìn lại, hay nghĩ xem ta đã làm và làm được những gì. Hãy tiếp gắng và quyết vươn tới những điều mình mong muốn, hãy tiếp tục học hành để làm hài lòng thầy cô cha mẹ. Nếu chúng ta làm được những điều đó, thì hãy nghĩ mà xem. Tuổi thơ của ta sẽ trở nên ý nghĩa biết bao.</span></a></p><a class="font-xs card-text text-dark"
