接上篇——

学单词必须在语境中学习，所以下面先写整句话，​再​学习单词和表达。

I'm a data scientist for VSP Global, where I build data stories, predictive models, and work with machine learning algorithms to help the organization improve their services, identify new markets, and a whole host of other things.

这句话中有几个可以看做是固定搭配的表达，也是一个数据分析师工作的关键职责和价值——build data stories, predictive models, identify new markets。 还有一个我第一次看到的表达a whole host of other things.

predictive models

Predictive analytics has many types of predictive models to choose from. Let's take a look at some of them ---

Naive Bayes Classifier

Decision Trees

Logistic Regression

Artificial Neural Networks

K-Means Clustering

identify new markets

identify这个词我肯定没到应用自如的程度。记下来这个表达，也期望能够应用它。

a whole host of

A very large number or collection of people or things.

We had a whole host of problems on opening night, but I think most of the issues have been resolved.

While the film has been receiving positive reviews from critics, there's a host of fans who are upset with the way it turned out.
