「Beginner」step1 ：初级入门

    A ： When you are in a restaurant and you want the waiter to bring
the bill， what do you do to attract his attention？

    B ： I just make eye contact with him and nod my head. Then I tell
him when he comes over to the table. Why do you ask ？

    A ： I went out with my girlfriend to a nice restaurant last night
and I noticed that many people shouted for the bill.

    B ： That seems a little impolite in such a restaurant.

    A ： That ‘s what I thought. I just thought I’d ask you and see
what you thought of it. Anyway， what did you do yesterday evening？

    B ： Well ， it was a warm evening， so I stretched my legs. I walked
along the canal for a couple of miles. Actually ， several other people
had the same idea. I saw Bill.

    A ： Did you？ How is he these days ？

    B ： He seemed ok. We didn‘t stop and chat because we were on opposite
banks of the canal. We just waved at each other.

    A ： I need to move some furniture. Could you help me to lift it？

    B ： Of course. What do you want to move first？

    A ： Let‘s move the sofa. Can you get a grip on the bottom at that
end ？ I’ll lift this end. I want to move it sideways in that direction.

    A ： Can you suggest a few exercise to help me get fit and stretch
my muscles a little ？

    B ： Sure. If you want to stretch your legs ， a good exercise is
to lift your knee in front of your body ， like this. It‘s a very simple
exercise， but very effective.

    A ： I need to excise my arms too. How can I do that？

    B ： One good way is to do push-ups. Another way is to use weights.
Make sure you grip the weights firmly. You don‘t want to drop them on
your feet ！

    A ： When I do push-ups ， should I bend my elbows so that my nose
touches the ground？

    B ： You don‘t need to bend your elbows that much. Bend them so that
your arms are at a 90 degree angle. The most important thing is to remember
to keep your body straight. Many people bend their bodies at the waist，
which reduces the effectiveness of the exercise.

    A ： What ‘s a good exercise for my chest muscles？

    B ： One that I recommend is that you lie on your back. You should
have a weight in each hand and stretch your arms out side of your body.

    A ： So I need plenty of space for this exercise.

    B ： Yes， you do. Lift the weight up ， keeping your arms straight
all the time.

    A ： Great. Thanks for you advice ！
