Hydraulic-powered exoskeletons (a kind of wearable robot that helps people move) that help wearers lift heavy objects or move freely have existed for years, but a team of Chinese researchers has recently introduced a unique new model inspired by the mythological centaur (a creature with a human upper body and a horse’s lower body in ancient stories). Named the “Centaur” power suit, it is basically a bipedal (two-legged) robot that is fixed to the wearer’s back, acting as an extra pair of legs that walks together with them. These robotic legs follow the user’s movements closely and adapt naturally when the user changes direction or speed. 

Most exoskeletons are attached to the user’s body and limbs to help them move, but the Centaur works as a separate pair of extra legs. This design has clear advantages: it can fully carry heavy loads without restricting the wearer’s movements, avoiding the uncomfortable sense of being restricted that traditional suits bring. It connects to the wearer’s back through a flexible connecting part with a nonlinear spring, which keeps stable when the force is small and remains comfortable even when carrying heavier loads, effectively separating human and robotic movement forces.

1.1.What makes the Centaur suit different from most exoskeletons?

A It copies a horse’s running style.

B It is attached to the wearer’s arms.

C It uses extra independent robotic legs.

D It reduces the user’s movement range.

解析：选C。C细节理解题。根据第二段第一句 “Most exoskeletons are attached to the user’s body and limbs... but the Centaur works as a separate pair of extra legs.” 可知，传统外骨骼附着在身体和四肢上，而 Centaur 作为独立的一对额外机械腿工作，这与 C 选项 “It uses extra independent robotic legs.” 完全吻合。文章第一段提到灵感来自半人马神话，但并未说它模仿马的奔跑方式，A 项错误。原文明确指出 Centaur 是固定在背部（fixed to the wearer’s back），而非手臂，B 项错误。第二段明确指出该设计 “without restricting the wearer’s movements”，不会限制活动范围，与选项相反，D 项错误。故选C。

2.2. What is an advantage of the Centaur’s design?

A It increases the wearer’s speed.

B It reduces the robot’s total weight.

C It fully replaces human limbs with robotic ones.

D It allows more freedom for the wearer.

解析：选D。D 细节理解题。 第二段描述设计优势时提到 “it can fully carry heavy loads without restricting the wearer’s movements, avoiding the uncomfortable sense of being restricted”，即机械腿独立承重且不妨碍穿戴者自由活动，这与 D 选项 “It allows more freedom for the wearer.” 含义一致。文章未提及该装备能提升穿戴者行走速度，A项错误。全文未讨论机器人自身重量是否减轻，B项错误。“fully replaces human limbs” 与原文不符，Centaur 是额外添加的机械腿，并非取代人体四肢C项错误。故选D。

3.3. How does the Centaur suit help people?

A By cutting physical tiredness.

B By thinking more quickly.

C By carrying all things alone.

D By controlling directions fully.

解析：选A。A 细节理解题。第三段最后一句 “greatly reducing the physical burden of walking” 明确表明该装备能显著减轻步行时的身体负担，即减少疲劳感，对应 A 选项 “By cutting physical tiredness.”。文章强调人负责决策与控制方向，并未提及提升人类思维速度，B 项错误。 “carrying all things alone” 错误，文中第四段主张人机协作（humans control... robots do the heavy work），并非完全由机器独立承担，C项错误。方向控制仍由穿戴者掌握（humans control the direction），而非装备全权接管，D项错误。故选A。

4.4. What is the author’s attitude toward the Centaur suit?

A Doubtful and worried.

B Slightly negative.

C Generally positive.

D Totally admiring.

解析：选C。C 观点态度题。作者在最后一段虽提及公众的负面反馈（mostly negative），但通过 “Despite the criticism, the Centaur’s creative combination of mythology and engineering offers a fresh perspective...” 这一转折句表明了对该发明的认可与期待。整体态度是总体肯定、积极评价，C项正确。A、B项与转折后的正面评价相悖，作者并未表达怀疑或消极情绪。D项“Totally admiring” 过于绝对，作者客观提及了批评声音，并非毫无保留地赞美。故选C。
