Scientists have developed a new surgical glue that could transform emergency treatments by sealing up critical wounds in the skin or the organs, without the need for staples or sutures(钉合或缝合).

It’s called MeTro. It was developed by researchers from both Harvard Medical School and the University of Sydney, led by Nasim Annabi, an assistant professor of chemical 【1】. The glue is made from a modified(改良的)human protein that responds to UV light, allowing the application and drying of the gel-like substance in just a minute.

According to the international team of researchers behind the glue, it could quite literally be a lifesaver, sealing up wounds in 60 seconds without stopping the natural 【2】 and relaxing of the organ or the skin it’s applied to. Wounds 【3】 with MeTro can heal up in half the time compared with stitches or staples, the researchers claim, and if surgery is required then MeTro can simplify that 【4】 too. It's also one of several ways researchers are exploring to engineer our body's own natural substances to help repair it when needed.

The 【5】 applications are powerful – from treating serious 【6】 wounds at emergency sites such as following car accidents and in war zones, as well as improving hospital surgeries.

MeTro is simple to apply, can be easily stored, and works closely with natural 【7】 to heal a wound. What’s more, it degrades without leaving any kind of poisonous leftovers in the body.

For now the trials are 【8】 to animal models. But human trials are in the works, and the results to date are incredibly 【9】. If the MeTro can be further developed into a 【10】 product, it could become an essential part of a first responder’s toolkit.

【解析】

这是一篇说明文。本文讲述了科学家已经开发出一种新的外科胶水，可以迅速密封皮肤或器官上的伤口，而不需要传统的钉合或缝合处理，该技术正处于试验阶段，具有广阔的应用前景。

【1】考查名词。句意：它是由哈佛医学院和悉尼大学的研究人员开发的，由化学工程助理教授Nasim Annabi领导。根据上文chemical可知本空需要名词，结合句意可知表示“工程”为engineering。故选D。

【2】考查名词。句意：据发明这种胶水的国际研究小组称，它可以在60秒内将伤口密封，而不会影响到皮肤或器官的自然扩张和放松，简直就是救命恩人。根据下文and relaxing可知本空需要-ing形式动词，结合句意可知表示“扩张”，expanding 与relaxing 相呼应，故选J。

【3】考查非谓语动词。句意：研究人员称，与缝针或缝合器相比，MeTro可以在一半的时间内愈合伤口，如果需要手术，那么MeTro也可以简化这一过程。本空需要非谓语动词做后置定语，且与wounds构成被动关系用过去分词，结合句意可知表示“治疗”故填treated。故选B。

【4】考查名词。句意：研究人员称，与缝针或缝合器相比，MeTro可以在一半的时间内愈合伤口，如果需要手术，那么MeTro也可以简化这一过程。本空需要名词，根据句意可知表示“过程”，故选G。

【5】考查形容词。句意：潜在的应用是强大的——从在紧急情况下处理严重的内部伤口，如车祸后和在战区，以及改善医院的外科手术。根据下文applications 为名词需要形容修饰可知本空填形容词，结合句意可知表示“潜在的；可能的”故为potential。故选C。

【6】考查形容词。句意：潜在的应用是强大的——从在紧急情况下处理严重的内部伤口，如车祸后和在战区，以及改善医院的外科手术。修饰wounds可知应填形容词，且结合句意可知表示“内部的”为internal。故选K。

【7】考查名词。句意：MeTro使用简单，易于储存，与天然组织紧密结合，来愈合伤口。根据上文natural可知应填名词，且结合句意可知表示“组织”名词为tissue。故选A。

【8】考查形容词。句意：目前试验仅限于动物模型。根据上文are可知应填形容词，且结合句意表示“局限于”为limited。故选F。

【9】考查形容词。句意：但人体试验正在进行中，迄今为止的结果令人难以置信地充满希望。根据上文 incredibly可知应填形容词，且结合句意表示“有前景的；有希望的”形容词为promising。故选I。

【10】考查形容词。句意：如果MeTro可以进一步发展成为一种商业产品，它将成为急救人员的必备工具。根据下文product可知应填形容词，且结合句意表示“商业的”形容词为commercial。故选H。
