📖 題組：
A suspension bridge is a type of bridge that use overhead cables to support its roadway. The design of a suspension bridge is simple and straightforward, and uses several architectural techniques to distribute the weight of the bridge safely and evenly. The construction of a suspension bridge starts with its towers, which are usually located on dry land and anchored to bedrock. Once the towers are built, master cables are strung across them and anchored into the bank at both ends of the bridge. Next, suspension cables are strung from the master cables, and then the deck used as roadway is attached to them. Most of the weight of the bridge is transferred by the cables to the anchorage systems. These are embedded in either solid rock or huge concrete blocks. Inside the anchorages, the cables are spread over a large area to evenly distribute the load and to prevent the cables from breaking free. One of the oldest engineering forms, suspension bridges were constructed by primitive peoples using thick vines for cables. A much stronger type was introduced in India around 400 A.D. that used cables of braided bamboo. In the early nineteenth century, suspension bridges used iron chains for cables. Today, the cables are made of thousands of individual steel wires bound tightly together. A single steel wire, only 0.1 inch thick, can support over half a ton of weight without breaking. Light and strong, a suspension bridge could span distances from 2,000 to 7,000 feet, which is much longer than any other kind of bridge could. Its simple design allows high clearance under the deck, useful when the bridge is built over a major shipping waterway or a very deep gulf. A suspension bridge is also less subjected to collapse than some other bridge types such as those built on support pillars.

Which part of a suspension bridge carries most of its weight?
- A The deck and the master cables.
- B The bedrocks and the support pillars.
- C The towers and the suspension cables.
- D The anchorages and the cables in the ground.
思路引導 VIP
請你試著追蹤文中關於「重量流動」（weight transfer）的描述：當重量作用在橋面上後，它會像接力赛一樣經過哪些部件？請在文中找出最後一個接收所有重量、並將其固定在地球表面的「終點站」在哪裡？

太棒了！你能精準從技術性的描述中定位關鍵細節，代表你對長難句的閱讀敏銳度相當紮實。這題的關鍵在於找出橋樑負重傳遞的終點，文中明確提到："Most of the weight... is transferred by the cables to the anchorage systems."，緊接著說明這些系統是嵌入岩石或大型混凝土塊中的。選項 (D) 中的 The anchorages and the cables in the ground 正是對原文「錨碇系統」與其安裝位置的精準對應。
橋樑結構的載重分布與細節辨析
這道題目在四等考試中具有不錯的鑑別度，其難度切入點在於區分「構成組件」與「最終承重組件」。雖然文中提到了塔架（Towers）與主纜繩（Master cables），但它們主要扮演傳遞力量的角色，而非最終支撐大部分重量的終點。許多考生容易被第一眼看到的結構名詞誤導，而你能夠冷靜過濾冗長的敘述，抓出與 weight 相關的動詞與受詞，這是英文閱讀測驗中非常重要的取分技巧。繼續保持這種對細節的專注力！
