芥末改善记忆力
New research coming out of Tohoku University says that wasabi（芥末） is good for the ability to remember. Wasabi, a spicy green paste, 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（抗氧化剂） and anti-inflammatory（消炎的） chemical called 6-MSITC that is rare（稀少的） in other plants. Scientists believe 6-MSITC might change how the brain’s “memory center—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（辣根酱） that has been colored 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.
6. According to Paragraph 2, who can have better memory?
A. Early sleepers.
B. Placebo takers.
C. People between 60 and 80.
D. People who keep eating wasabi for 3 months.
7. What in wasabi has something to do with memory improvement?
A. Dishes.
B. 6-MSITC.
C. Placebo.
D. Hippocampus.
8. 特色 考法 信息还原题 Which can be the best to fill in the “ ▲ ”?
A. wasabi is not a popular paste around the world
B. most people in Japan don’t think the research is true
C. most wasabi that is served in Japan is not real wasabi
D. fresh wasabi is so expensive that people can’t eat it very often
9. 特色 考法 写作目的题 What’s the main purpose of the passage?
A. To discuss the health risks of eating spicy food.
B. To explain the way of making sushi with wasabi.
C. To compare real wasabi with green-colored horseradish.
D. To introduce a new study on wasabi from a Japanese university.

答案
6.D 细节理解题。根据“After three months, the people who took the wasabi had much better results in memory tests.”可知,持续食用芥末三个月的人记忆力更好。故选D。
7.B 细节理解题。根据“Wasabi was already known to have an antioxidant and anti-inflammatory chemical called 6-MSITC that is rare in other plants. Scientists believe 6-MSITC might change how the brain's ‘memory center—hippocampus’ works.”可知,6-MSITC与记忆力改善相关。故选B。
8.C 信息还原题。根据“Instead, it is white horseradish that has been colored green. Real wasabi is difficult to grow and, as a result, is very expensive.”可知,空后说我们常见的芥末是被染成绿色的辣根酱,真正的芥末难以种植且非常昂贵,选项C“日本供应的大多数芥末不是真正的芥末”符合语境。故选C。
9.D 写作目的题。根据文章首句“New research coming out of Tohoku University says that wasabi is good for the ability to remember.”及文章其他内容可知,本文主要介绍了日本东北大学关于芥末的一项新研究,包括研究过程、芥末中对记忆有影响的成分等内容。故选D。
