问题     These days, science may have dissected almost every element of
our diet, but many of us still feel at the sea. Even when sticking to【S1】________
official advice, healthy foods that seem to energize one person can cause
another to feel fatigued and bloated. In 2015, scientists from Israel
tracked blood sugar levels of 800 people over several days, making the
surprising discovery individuals’ biological response to identical foods【S2】________
varied wildly. Some people had a blood glucose "spike" after eating
sugary ice cream, when others’ glucose levels only increased with【S3】________
starchy rice—a finding at odds against conventional wisdom.【S4】________
    Our bodies’ idiosyncratic handling of nutrients seem to be down to【S5】________
our genetics, the microbes in our gut, and variations in our organs’
internal physiology. Clinical trials like those are pioneered by Lind have【S6】________
given us general dietary guidelines, but nutrition research tends to assume
all humans are the same, and so can miss the nuances and specifically【S7】________
needs of the individual.
    In the next 10 years, the emerging field of "personalized nutrition"
will use genetic tests to fill in those gaps to offer healthy eating guidance
tailoring to the individual. Some companies have already tested your【S8】________
DNA and offered dietary advice—but the advice can be hit-and-miss.
By 2028, we will understand much more about our genetics. Dr. Jeffrey
Blumberg, a professor of nutrition science and policy at Tufts University
in Massachusetts, is one of the most outspoken advocate of this new【S9】________
science. He insists that DNA testing will unlock personalized nutrition.
"I’ll be able to tell you what kinds of fruits, what kinds of vegetables
and what kinds of whole grains you should be choosing, or exactly how
often," he says.
    Sadly, personalized nutrition makes cook meals for the whole【S10】________
family a little bit more taxing.
【S6】
选项
答案∧are pioneered→which／that或去掉are
解析 定语从错误句。本句意为“像林德率先进行的那些临床试验为我们提供了总体的饮食指南……。”分析句子结构可知，本句的主干是“Clinical trials…have given us…”，其中，like those是介词短语作定语，修饰主语。本句主干已完整，所以those后的内容应是定语从句，those是先行词，故此处缺少关系词which或that。此处也可以视作过去分词结构pioneered by Lind作后置定语，修饰those，故are多余。
