Many expressions that we use in American English come from novels. Today we will look at some of them from " Alice in Wonderland" in detail.

The story is about a young girl falling down a rabbit hole. When she finally l    1    , she finds herself in a strange world and meets some strange characters.

The f    2    character Alice meets is the White Rabbit, who runs past her and says some strange words. Alice chases（追赶）him，and that is where her adventures b    3    . In English, chasing a white rabbit means chasing an i    4    clue and finding yourself in a misleading situation.

Then, as she runs after the rabbit，she falls down the rabbit hole into Wonderland. To fall down the rabbit hole can mean to enter a confusing(令人困惑的)situation. H    5    , usually we use this expression to mean we get i    6     in something to the point of distraction(分神). It often happens by accident and is about something not that meaningful.

Later in the story, Alice meets the March Hare and the Hatter at a crazy tea party. Hares(野兔)have long been thought to behave excitedly in M    7     , which is their mating(交配)season. Scientifically, this may not be true. But to be mad as a March Hare means that s    8     is completely mad，or crazy. The expression mad as a Hatter also means to be completely crazy. Of the two，mad as a Hatter is more c    9     . But don't tell the March Hare. Who knows how he will react（反应）!

Near the end of the story, Alice meets the Queen of Hearts. A woman who is called a Queen of Hearts likes c    10    others and always tries to control everything and everyone around her.

Have you ever heard of “National Smile Month”? It starts on the 14^th of May in the UK. During this month, people     1     (make) to think about the importance of brushing their teeth, eating less sweet foods and going to see the doctors from time to time.

The British are well-known     2     their bad teeth. Even a dictionary has the     3     (express) “British Smile”, meaning “Any smile with bad teeth”. However, in America, the “Hollywood Smile” gets     4     (it) name because American movie stars are so     5     (pride) to show off their beautiful teeth.

But what’s smiling in the UK? Do the British smile a lot,     6     do they look sad all the time? It’s said that the British don’t often show their feelings. But actually, it all     7     (depend) on the situation. For example, the British aren’t allowed     8     (smile) in passport photos. But if you’re at a party, you’ll find everyone smiles     9     (happy) and loudly.

So, if you go to the UK, the British will probably greet you with     10     big smile, just like people in other countries.
