Inflation as measured by the GDP deflator 【slackened】 in most of the G7 countries.
A、lacked
B、weakened
C、sharpened
D、moved
【正确答案】:B
【名师解析】:题目中的句子 "Inflation as measured by the GDP deflator slackened in most of the G7 countries." 描述的是G7国家中大多数国家的通货膨胀率有所减缓。选项B "weakened" 意为"减弱"或"变弱",与句子中的 "slackened" 意思相近,都传达了通货膨胀率下降或减缓的意思。因此,选项B是正确的答案。其他选项A "lacked" 意为"缺乏",C "sharpened" 意为"变得尖锐",D "moved" 意为"移动",都与题目中描述的通货膨胀率减缓的情况不符。
