Learning new words is never easy. Within 24 hours, you may forget about 80 per cent of the words you memorize. So what is the best way to memorize new words The answer is to review! That is to say, you have to see new words again and again.
According to psychologists (心理学家), you need to memorize new words more than seven times to turn them into your long-term memory. A good way to do this is to review new words from time to time. For example, after learning new words, look at them again on the same day. Then, review them a week later, and then ten days after that.
However, it is not enough to repeat new words or to review them in the same way again. It is much better to use new words in different ways. For example, you can use pictures to memorize new words or use new words when you write in your diary. Take your time, and you will keep new words in your mind for a long time.
1. How can you turn new words into your long-term memory according to psychologists
A. By memorizing them over seven times.

D. By listening to them from time to time.
2. After learning new words, we should first review them ________.
A. ten days later B. seven days later
C. next day D. on the same day

A. To review new words in the same way again.

1) 如果 if 条件句讲述自然规律，肯定会发生的事情或客观事实，主句和if从句都用一般现在时态。（主现从现）

(主现从现) If you put a piece of paper into water, it gets wet.

如果我有足够的钱， 我会买一辆车。
(主祈从现) Be careful when you cross the road. 过马路时要小心。
Put up your hand if you have any questions to ask.
如果你们有问题要问的话，请举手。
(主情从现) If I get there early, I can see the doctor quickly.
如果我早早地到那里， 我就可以快点看病。
【注意】 此处if引导的从句，还可由 when， as soon as(一…就…), （not）…until （直到…才），unless(除非)来引导。
The traffic must stop when the light are red.当红灯亮时，交通必须停止。
