New research coming out of Tohoku University says that wasabi(山葵）is good for the ability to remember. Wasabi, a spicy taste, is widely used in Japanese dishes.
A recent study tested people between the ages of sixty and eighty. Some of the test members took a certain amount of wasabi every night before going to bed. The others were given a placebo(无效对照剂). After three months, the people who took the wasabi had much better results in memory tests. The placebo-takers did not show any improvement.
Wasabi was already known to have an antioxidant and anti-inflammatory called 6-MSITC that is rare(稀少的) in other plants. Scientists believe a chemical called 6-MSITC might change how the brain’s memory centre—hippocampus(海马体）works. They will continue researching with the hope that wasabi can help people that are experiencing dementia(痴呆症).
This new research seems to be good news for sushi eaters. However, ▲. Instead, it is white horseradish(辣根）that has been coloured green. Real wasabi is difficult to grow and, as a result, is very expensive. It also needs to be made and served fresh at once before being eaten.

解析
【分析】
做这类英语阅读理解题时，需先通读原文把握核心内容，再针对各题目定位原文对应信息：19题是细节题，需定位第二段实验结果；20题找山葵中与记忆相关的物质，定位第三段；21题是推理题，结合前后文转折逻辑填空；22题是主旨题，梳理全文核心内容判断目的。
【解析】
19题：定位第二段，实验中“吃山葵的人三个月后记忆测试结果更好”，对应选项D；A选项早睡者未提及，B选项无效对照剂组无改善，C选项60-80岁是测试人群而非记忆更好的群体，排除。
20题：定位第三段，明确提到“6-MSITC可能改变大脑记忆中心的工作，与记忆改善有关”，对应选项B；A选项是山葵的用途，C选项是无效对照剂，D选项是大脑记忆中心，均排除。
21题：第四段前半句说对寿司爱好者是好消息，后半句转折说“是染绿的辣根而非真山葵”，中间需衔接“提供的山葵并非真的”，对应选项C；A选项山葵是否受欢迎未提，B选项日本人是否认为研究真实未提，D选项山葵价格是后续原因，排除。
22题：全文围绕“日本东北大学关于山葵对记忆有益的新研究”展开，介绍实验、成分、现状，对应选项D；A选项讲辛辣食物健康风险与原文无关，B选项讲寿司制作方法未提，C选项对比真山葵和辣根是细节而非主旨，排除。
