Modals
be able to后接动词原形，表示某人做某事的能力，可用于大多数时态。用于过去时态时，还可以表示“某人过去或当时成功地做了某事”。
I will be able to speak Japanese in another few months.
再过几个月，我就能讲日语了。
They were able to escape from the building when the fire broke out.
火灾发生时，他们设法从那栋建筑里逃了出去。

I have to leave because of the bad weather.
因为天气不好，我不得不离开了。
Function of Modals 2
have to
had better后接动词原形，意为“最好”，用于现在时或将来时，可用于一切人称，没有任何词形变化。had better 的否定式是在其后加 not，疑问式是把 had 和 not 提前。

She had better not tell lies any more.
她最好再也别撒谎了。
Function of Modals 3
had better
If you dare not try a “painful” diet to stay healthy, this new app is the perfect solution — and you needn’t pay for it! The app works by quickly showing photos of different food. All you have to do is select the photos of healthy food. Then you’ll be able to train your brain to select healthy food in real situations. So, if you’re a sugar addict and aren’t able to say no to chocolate or cola, you had better download it now!
Underline the modals and talk about their meanings.
2) need 表示“需要”或“必须”，作情态动词时，用于否定句或疑问句

Table manners in China
1 Backyard BBQ, Kansas City, US
The most tender steak I’ve ever had! The barbecue gives it that famous smoky flavour, and it comes with a shiny sauce that’s very, very spicy!
56 reviews
2 Bund 59, Shanghai, China
A bowl of soup with a large, round meatball! The meatball is cooked through, which looked slightly pink inside. Incredibly soft and juicy — it melts in the mouth!

3 Antonio’s Pizzeria, London, UK
Worst pizza ever! I ordered a large vegetarian pizza, but it was tiny! It was served cold and came with some sort of sticky sauce which tasted bitter and smelt really fishy!

4 Madame Laurent’s Bakery, Paris, France
You’ve got to try the strawberry cheesecake. It’s smooth and creamy with fresh strawberries, which give it a lovely sweet and fruity taste. Highly recommended!
