Q39:

Unlike the body’s inflammatory response to cuts and sprains, with widespread swelling and stiffness immobilizing the injured area until it heals, the body’s response to sunburn is more localized and resulting in a distinct line dividing affected and unaffected areas of the skin.

1. with widespread swelling and stiffness immobilizing the injured area until it heals, the body’s response to sunburn is more localized and resulting
2. where the injured area is immobilized with widespread swelling and stiffness until it has healed, sunburn generates a more localized response in the body, which results instead
3. with the injured area immobilized by means of widespread swelling and stiffness until healing, sunburn generates a more localized response in the body, one resulting
4. in which widespread swelling and stiffness immobilize the injured area until it has healed, the body’s more localized response to sunburn results
5. in which widespread swelling and stiffness immobilize the injured area until healing, instead, the body’s more localized response to sunburn results

我彻底迷茫啦 答案选D until it has healed 明显不对的啊 再加上which指代什么？怎么会前面还有个in 啊这边

 until it has healed 是对的，不明白“明显不对”从何说起。

which指 response；In也是要的，后面的状况出现在这个response之中，你仔细再把原句意思理解下。。。。

谢谢提醒 In我看出来啦

我就觉得应该是Until it is healed 不明白为什么要用个完成时啊。。。

before和after这两个词通常不用完成时表示动作先后，其他的比如until，用完成时表示

动作先后没什么问题啊。
