Goel and his team developed several versions of Jill Watson before releasing her to the online forums.

发布到线上论坛之前，Goel和他的团队研发了好几个版本的Jill Watson.

词法：release：计算机领域指发布代码，编译程序等。forum此处指在线课程论坛。

句法：主句是简单的主语，谓语，宾语，before后面的动宾状结构。

翻译要点：汉语中状语前置。

逻辑整理：第一段，概况了问题，及解决方法。本段，详细描述解决问题的整个过程。这一段是说明文中典型的说明程序步骤过程的说明文。存在着潜在的先后顺序关系。

At first, the virtual assistant wasn't too great.

起初，虚拟助手不太理想。

词法：at first ,一般理解是首先，但是实际首先，一般指最初，不完美的状态，暗指后来的变化。

逻辑整理：详细描述过程。

But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. 但是，Goel和他的团队查阅了最初的讨论论坛，找到40000个课程开课以来提出的问题。

词法：重点是source用作动词，指的是查找源头的意思，可以不能直接翻译，否则无法将意思表达明白。另外，launch是启动计算机课程的意思。

句法：主语，谓语，宾语之后，是to do引导的目的状语，to do 后面的名词作宾语，其后又出现了定语从句，定语从句之后，又出现了since引导的简单时间状语从句。

翻译要领：不要简单的单词对译，要结合上下文的语境。

逻辑整理：本句承接上句不理想，提出了具体的改进措施，结合数字，让说明更加具体。

Then they began to feed Jill the questions and answers.

然后，将答案输入给Jill。

词法：feed，不是指喂养的意思，是输入信息的意思。

句法：begin后面出现了to do 成分，to do 后面的宾语，既有人又有物，需要分清，真正的宾语是后者.

逻辑整理：具体的改进措施。

After some adjustment and sufficient time, Jill was able to answer the students' questions correctly 97% of the time.

在稍作调整及时间充分的前提下。Jill97%的情况下，能准确回答问题。

词法：此处sufficient time指的是给虚拟助手充分的时间，也就是说不能催得紧。after，表面上是之后的意思，实际上，是表面条件。

句法：英语中状语成分前置时，一般要用逗号与主句隔开。

翻译要领：不可以单词对译，要结合上下文，以准确翻译语义为第一原则。

逻辑整理:本句是描写改进以后虚拟助手的运作情况。

Many students drop out of online courses because of the lack of teaching support .When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade.

The virtual assistant became so advanced and realistic that the students didn't know she was a computer. The students, who were studying artificial intelligence, were interacting with artificial intelligence and couldn't tell it apart from a real
