高考英语作文划线【一】
无论是承上、还是启下，抑或是承上启下，带来的好处都是使文章的结构严谨。
例如： 为什么我国的石拱桥会有这样光辉的成就呢？首先，在于我国劳动人民的勤劳和智慧。他们制作石料的工艺极 其精巧，能把石料切成整块大石碑，又能把石块雕刻成各中形象。在建筑技术上有很多创造，在起重吊装方面更有意想不到的办法。如福建漳州的江东桥，修建于八 百年前，有的石梁一块就有二百来吨重，究竟是怎样安装上去的，至今还不完全知道。其次，我国石拱桥的设计有优良传统，建成的桥，用料省，结构巧，强度高。 再其次，我国富有建筑用的各种石料，便于就地取材，这也为修造石桥提供了有利条件。
文中这个划线句子就是针对过渡句的结构作用出的试题。“这样辉煌的成就”概括了上文赵州桥的历史、结构、造型特点，具有承上作用，“为什么”这个疑问代词，概括了这一段的主要内容，所以具有启下的作用。
综上所述，在这个段落中，划线句子的作用就是：承上启下，上承接我国石拱桥取得的辉煌成就，下引出取得成就的原因，使文章架构严谨。

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!
Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.
Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.
