For years, the discussion on the development of synthetic （合成的）, lab-grown organs has been a major talking point. Many see it as a controversial subject, with ethical leanings and understandings. Others, though, see the process of lab-grown organs as an essential part of making sure we can give everyone the help that they need. However, advancement in the process has been a slow-burning development.

The University of Pittsburgh, though, has been working on a process to help make sure that lab-grown livers（肝脏） could be created. They have been using machine learning and synthetic biology in combination with one another to try and find the ideal solution to the creation of entirely safe lab-developed livers. The aim is to help speed up the process of creating a human liver with real blood and bile management systems. So far,though, the process is still very much in the development stage. The testing in mice,though, did show that when mice with failing or failed livers were given the lab-grown alternative, their lifespan was increased. While it cannot be said for certain that it works without qualification, there is already a clear interest in the use of lab-grown organs.

The aim is simple—find a way to avoid having to wait on the loss of another human life to save a sick life. With lab-grown organs, that could become a reality in the future.Testing, though, is going to be a long-term process; even with the progress made, real-life usage is still some way off.

Are lab-grown organs a realistic proposition? It certainly appears to be the case. Indeed, the synthetic biology and machine learning combination in Pittsburgh has produced some of the most positive, promising results seen in some time. The hope is that they can continue to grow and get better over time, and that the process can continue to develop to the right standard without any complications or delays.

If lab-grown organs have become a talking point that you find concerning, then the progress being made in Pittsburgh might assuage some fears. You should absolutely take a closer look at lab-grown organ processes being developed, though, as the progress being made in Pittsburgh is the most promising news in some time.

Ⅰ. Difficult sentences in the text

1. While it cannot be said for certain that it works without qualification, there is already a clear interest in the use of lab-grown organs. 虽然不能肯定地说它能在没有限定条件的情况下工作，但人们对使用实验室培育的器官已经有了明确的兴趣。

【点石成金】本句是一个主从复合句。 While it cannot be said for certain that it works without qualification是连词while引导的让步状语从句，此处连词while意为“虽然；尽管”，相当于although或though。 注意：①while引导的让步状语从句通常位于主句的前面；②while引导让步状语从句时，如果主句与从句主语相同，从句中的主语和谓语中的be动词都可以省略。

2. The hope is that they can continue to grow and get better over time, and that the process can continue to develop to the right standard without any complications or delays.我们希望，随着时间的推移，它们能够继续成长并变得更好，并且这个过程能够继续发展到正确的标准，而不会出现任何并发症或延迟。

【点石成金】本句是一个主从复合句。 that they can continue to grow and get better over time, and that the process can continue to develop to the right standard without any complications or delays是由that引导的两个并列的表语从句，that不能省略。注意：表语从句中，that一般不能省略。
