答案：【解析】：
(1) 本題考查主謂一致。主語"Bobby and Sam"是復(fù)數(shù)，因此需要用復(fù)數(shù)形式的動詞，選項C "are doing a project" 是正確的現(xiàn)在進(jìn)行時形式。
(2) 本題考查動詞的-ing形式作賓語。動詞start后面應(yīng)該接動詞的-ing形式，表示開始做某事，所以選項A "drawing" 是正確的。
(3) 本題考查介詞的使用。在英語中，描述某物在樹上通常用介詞on，特別是當(dāng)描述的是樹上的果實或葉子等自然生長的部分時。因此，選項B "on" 是正確的。
(4) 本題考查情態(tài)動詞的用法。should not后面應(yīng)該接動詞原形，表示不應(yīng)該做某事。選項C "swim" 是動詞原形，且符合句意“你不應(yīng)該在這里游泳”。

B.Then I draw some nice things and write some words on it.

D.First, I take out a piece of paper and fold it in half.

)?(
D
)?(
B
)
答案：【解析】：
這是一個句子排序的問題。我們需要根據(jù)句子的內(nèi)容和邏輯關(guān)系，將它們按照正確的順序排列。
A句：My mother's birthday is coming.（我媽媽的生日快到了。）這句話是引出話題，說明為什么要制作卡片。
C句：I want to make a card for her.（我想為她制作一張卡片。）這句話表明了作者想要為媽媽制作卡片的意愿，是對A句的回應(yīng)。
D句：First, I take out a piece of paper and fold it in half.（首先，我拿出一張紙并把它對折。）這句話描述了制作卡片的第一步。
B句：Then I draw some nice things and write some words on it.（然后我在上面畫了一些漂亮的東西并寫了一些字。）這句話描述了制作卡片的下一步，即在紙上進(jìn)行裝飾和書寫。
根據(jù)上述分析，我們可以得出句子的正確順序應(yīng)該是：A?C?D?B。
【答案】：
A?C?D?B
