解题策略
FOUR-STEP STRATEGY先做 26、28 空(细节照应最好找)
这两空有直接的“文字抓手”:26 空靠时间对照——前句是 ancient China, Rome, Egypt and Greece(古代),选项 F 用 Today(今天)与之呼应;28 空靠代词指代——选项 C 的 This 指代前句的 clear the numbers(清除数字)。先拿下这两空,信心和范围一起到手。
每确定一空,就划掉对应选项
六选五有 6 个选项、5 个空位,必有 1 个多余项。每确认一个就把它从选项列表里划掉(写在一旁的草稿纸上),剩下的选项越少,后面的匹配就越简单,也能顺手盯住那个被“剩下”的多余项。
再做 27、29 空(概括句 / 并列举例)
27 空是后句的概括句:后句 Each bead above the bar represents five while each bead below the bar represents one 在讲上下珠数值不同,选项 D 正是它的总结(Beads in the two parts have different values);29 空与前句构成并列举例——“To represent one…”讲表示“一”,选项 A 接着讲表示“五”,一与五成对出现。
最后做 30 空(转折 + 话题推进)
前句说用算盘做加减 quick and easy(又快又容易),选项 E 用 However 转折,把话题从“加减”推进到“乘除”,与后句“熟练者甚至能算平方根”形成“难,但高手做得到”的递进。剩下没人要的 B 项说“算盘慢、很多人不喜欢”,与全文肯定算盘的立场相矛盾,即多余项。多余项特征:内容似乎与话题沾边,却找不到任何一处空白可以承接它;本文的 B 项还多了一层硬伤——But 与 much slower 搭配不当。

PASSAGE + OPTIONS · 左文右选,同色关联P1 People started using the abacus(算盘)over four thousand years ago to calculate numbers. It was used in ancient China, Rome, Egypt and Greece. 26F The Chinese abacus is called Suan Pan and is made of beads and thin rods. The beads and rods are usually kept in a wooden frame. A horizontal bar divides the abacus into upper and lower parts. The upper part has two beads on each rod and the lower parts have five beads on each rod. 27D Each bead above the bar represents five while each bead below the bar represents one. There are more than seven rods for a Chinese abacus. Starting from right to left, the first rod is one, the next rod is ten, the third rod is a hundred, etc.
P2 When using the Chinese abacus, the first thing to do is to clear the numbers. 28C When a bead above the bar is moved down, or when a bead below the bar is moved up, it becomes active and takes value. Recording numbers on an abacus is quite easy. To represent one, simply push up one bead on the first rod below the dividing bar. 29A It is quick and easy to add or subtract numbers with an abacus. 30E A really good abacus user can even calculate square roots.
