Adding milk to a cup of tea can destroy its ability to protect against heart disease, according to research.
A small German study found drinking black tea significantly improved the ability of arteries to relax and expand to keep blood pressure healthy.
But the European Heart Journal paper also found proteins in milk, called caseins, blocked this effect.
有意思的是block這個字, 作動詞解釋時它的用法如下:
1. 阻塞,堵住,封鎖
A piece of rock had fallen and blocked up the path.
一塊岩石掉了下來,堵住了路。
2. 阻擋,妨礙,阻止
They were blocked from joining the club.
他們被阻加入該俱樂部。
3. 限制;凍結
因此從字面上事實上不難了解大意
, 但我的問題是, 如果換成是我, 可能會用reduce (降低)這個字或其他的字, 不會想到這個我們平常用在”封鎖”或是最常用它的名詞:”(四面圍有街道的)街區”。
