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! Soon, you'll be filling your cupboards with real healthy food.
Underline the modals in the introduction to an app and talk about their meanings.

While going on your first trip to the UK is exciting，new and different customs can also be confusing. Table manners are no exception. But don’t worry—here are some tips：
You 1 wait until everyone else has been served before you start eating.
Sometimes there are so many knives and forks that you 2___________ pick them up in case you get it wrong. The trick is to start with the ones on the outside.
have to
dare not
When you finish your meal，you3 place the knife and fork together on your plate with the handles at the four o’clock position.
Table manners，however，can differ in different situations. For example，you 4 use a knife and fork when eating a hamburger or pizza. Just remember：when in Rome，do as the Romans do，and you will 5 enjoy the local cuisine!
