Grit is passion and perseverance for very long-term goals. Grit is having stamina.

Grit is stacking with your future,day in,day out ,not just for the week,not just for the month,

But for years ,and working really hard to make that future a reality.

Grit is living life like it's a marathon,not a sprint.

注意点:

1 grit 发短元音。't' 浊化弱化

2 passion 发的夸张,饱满

3long-term goals  难点-long 后鼻音

Goals. 舌头往上走,往上翘顶住上颚。

3 stamina  耐力 持久的耐力 ,'t'浊化

4 stack ,'t' 要浊化

5 week 长元音

6 for the week-the 弱读

This is Scientific American 60 second Science.I'm Sophie Bushwick.Got a minute?A steaming mug of coffee helps me wake up in the morning.But it can do more than just keep your eyes open .Caffeine may actually boost your memory.Researchers gathered 160 uncaffeinated adults,people who consumed less than 500 milligrams of caffeine a week .These decaf subjects looked at Pictures of various objects,than took either a placebo or a pill containing 200 Milligrams of caffeine.That's roughly the amount you'd get from two cups of coffee.The next day,participants examined a fresh set of pictures:Some brand new,some from the previous day,and some that just looked similar to the old images.Both groups could identify new and old pictures equally well.But the caffeinated group was better at correctly labeling images that were similar but not identical.The placebo group tended to mistakenly identify these pictures as the same as the previous day's。The work is in the journal Nature Neuroscience.So caffeine does more than help you stay alert。 get the picture?The study subjects did.Thanks for the minute for scientific American 60-second science. I'am Sophie Bushwick.
