解析
本题考查动词短语的语境应用能力，需要根据句意选择最合适的短语替换下划线部分。解题核心在于：
- 理解原句含义，明确空缺处需要表达的意思；
- 匹配短语的固定搭配和用法，注意短语的语态、形式（如动名词、动词原形等）；
- 排除干扰项，结合句中逻辑关系（如因果、否定等）确定正确答案。
第（1）题
原句：Thousands of university students establish their own businesses every year in China.
关键点：
- “establish”意为“建立”，但更符合“创办企业”语境的短语是 set up（创办、建立）。
- “set up”强调从无到有的创建过程，与“businesses”搭配更自然。
第（2）题
原句：People help others because they care，so they expect nothing in exchange.
关键点：
- “in exchange”意为“作为交换”，但更常用且更简洁的表达是 in return（作为回报）。
- “in return”常用于表示“作为帮助的回报”，与句中“help others”逻辑更连贯。
第（3）题
原句：Establishing relationships with other entrepreneurs will be helpful when you are looking for support or suggestions for your start-up.
关键点：
- “be helpful”意为“有帮助”，但更符合口语化表达且强调“恰到好处”的短语是 come in handy（派上用场）。
- “come in handy”常用于建议或展望未来的情境，与“when you are looking for support”呼应。
第（4）题
原句：When starting a business，you need to avoid being obsessed with trivial things or detailed planning.
关键点：
- “being obsessed with”意为“沉迷于”，但更符合“被细节阻碍”的表达是 being hung up on（过分关注）。
- “hung up on”强调因细节而停滞不前，与创业初期需聚焦核心目标的语境更贴切。
第（5）题
原句：After he lost his job，he had to depend on his parents for the money or food that he needed.
关键点：
- “depend on...for the money or food”意为“依靠...获得资源”，但更简洁且强调“生活来源”的短语是 live off（靠...生活）。
- “live off”直接表达“依靠他人维持基本需求”，与失业后的语境更匹配。
