There is a zoo near my house. I like {#blank#}1{#/blank#} there. There are many {#blank#}2{#/blank#} in it.
Look! There is a koala {#blank#}3{#/blank#} the tree. Isn't he {#blank#}4{#/blank#} ? Under the tree, there is a {#blank#}5{#/blank#} . Her neck(脖子) is so long. She is a lovely girl. {#blank#}6{#/blank#} is the panada? She is eating the bamboo(竹子). She's {#blank#}7{#/blank#} shy. But the elephant is interesting. He is playing with kids with his{#blank#}8{#/blank#} nose. They are very funny. Look! In the pool, there are two dolphins. They are playing with {#blank#}9{#/blank#} balls. {#blank#}10{#/blank#} happy they are !

    People also love trying to memorize the digits of pi and {#blank#}1{#/blank#} against others to see who can remember the most. Many teachers hold class{#blank#}2{#/blank#} to see how many numbers their students can memorize. The Guinness World Record for{#blank#}3{#/blank#} the most digits of pi is held Suresh Kumar Sharma of India, who successfully recited pi out to 70,030 decimal places.

    Above all, Pi is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with pi-related games and activities. This year, Princeton, New Jersey, held a birthday party for Albert Einstein whose birthday also{#blank#}4{#/blank#} on March 14. There was also a "Walk a Pi Event "where people walked 3.14 miles together. Just like the number itself, the possibilities for Pi Day are truly endless.

A: What's that, Nick?

B: Oh, it's my {#blank#}1{#/blank#}, Come and look at it, Bob.

A: Is it a model(模型) car?

B: Yes, and it's a "clean car".

A: It's {#blank#}2{#/blank#}, How does it go?

B: It uses sunlight or {#blank#}3{#/blank#}.

A: That's great. The air would be clean {#blank#}4{#/blank#} all the cars were like it.

B: You're right, Bob.

A: Could you make one for me, Nick?

B: Sure. You'll have a {#blank#}5{#/blank#} one next Monday.

A: Thank you.

    People {#blank#}1{#/blank#}kites for at least two thousand years. Kites are fun to fly, but did you know there are also practical reasons to fly them? It {#blank#}2{#/blank#}that, in 1750, Benjamin Franklin flew a kite in a thunderstorm to verify that lightning was electricity. The Wrights brothers tested many of their aviation theories by flying early airplane designs as kites. This allowed them to experiment different wing shapes and controls from the ground before their first flight in 1903.

    No matter why you fly kites, {#blank#}3{#/blank#} attention to the weather for good kite-flying conditions. The wind should be between 5 and 25 miles per hour. It should be neither too calm nor too strong. Don't fly a kite when it {#blank#}4{#/blank#}. It's better {#blank#}5{#/blank#} an open space. Don't let your kite be eaten by a tree or bump into people, buildings or power lines.
