语法选择
(2025 广州六中二模改编)“Drink eight cups of water.” All of us
__1__ the advice for many many times.But if you fall short, don't worry.
That advice is probably quite wrong, anyway.That's according to __2__
new study.It found that for most healthy adults, __3__ eight cups of water
a day is unnecessary.But nor is it dangerous.If you do drink eight cups of
water, you are probably just going to be spending more time in the
bathroom.
In fact, this misunderstanding has something to do with the suggestion
before.Early in 1945, the U.S.National Research Council advised adults
__4__ about 1.9 liters of water daily.The suggestion is about a person's
total daily intake of water from fruit, vegetables and soup.But it has been
__5__ misunderstood.Many people believe that they should drink eight
glasses of water every day.
So, have you ever wondered __6__ water you need to drink daily
The study found that it's different from one person to __7__.It depends on
__8__ age, size, physical activity and the weather in the city where you
live.
Our needs for water are the highest between the ages of 20 and 50.
After that, the needs slowly go down __9__ our metabolism(新陈代谢)
slows down after the age of 50, and our needs for water go down, too.
Also, since men usually have __10__ bodies than women, they need
more water.People whose jobs need more physical activities need more
water than those who work in the office.And people who live in hot places
are in need of more water than those who live in the place __11__ cold
weather.
In conclusion, most of you don't really have to worry about not having
enough water yet.__12__ you also don't have to work out the exact amount
of water you need by measuring.Just drink whenever you are thirsty.Water
is the best choice.Coffee and tea __13__ fine as well.But drinks with sugar
must __14__, which can cause lots of __15__ problems.Hopefully,
everyone can stay fit and have unlimited happiness.
