Liên quan đến vấn đề viết báo khoa học hay luận án, có khi nào bạn cảm thấy không biết bắt đầu câu văn như thế nào? Tôi nghĩ chắc là có. Kinh nghiệm của tôi ngày xưa là như thế. Có khi nghĩ cả ngày mà chưa ra câu văn đầu tiên là gì, viết sao cho "ấn tượng", mặc dù đã có ý tưởng rồi. Trong khoa học có nhiều câu văn "quen quen" mà chúng ta có thể dùng một cách luân phiên để cho bài báo hay luận án đọc cho suôn. Tôi đã sưu tầm nhiều câu văn như thế, và trong loạt bài này sẽ chia sẻ cùng các bạn.
Người ta thường hay nói "vạn sự khởi đầu nan", và tôi thấy câu này rất thích hợp trong việc viết bài báo khoa học. Sau khi đã làm xong thí nghiệm, hay làm xong nghiên cứu, với một đống số liệu, và những ý tưởng khá rõ ràng, chúng ta có khi không biết bắt đầu câu văn như thế nào. Đó là tâm trạng chung của rất nhiều nghiên cứu sinh khi mới bắt đầu viết báo khoa học hay viết luận án. Đó cũng là tâm trạng của người trình bày trong hội thảo: phải bắt đầu bằng câu nói gì cho hay, để gây sự chú ý của khán giả. Kinh nghiệm của tôi cho thấy câu văn đầu mà trôi chảy thì bài nói chuyện hay bài báo khoa học sẽ trôi chảy theo.
Nhưng trong bài báo khoa học có nhiều phần, và mỗi phần có chức năng khác nhau, cho nên câu văn cũng phải phù hợp với những chức năng cụ thể. Sau đây là những câu văn mà các bạn có thể sử dụng để tô thêm màu sắc cho bài báo khoa học:
