2. When scientists inspected the bnes, they were surprised t find that these dinsaurs culd nt nly run like the thers but als climb trees. [點(diǎn)撥] 本句中的t find that ...是不定式作原因狀語(yǔ)。不定式用來(lái)表原因時(shí)，常修飾表示情感、心理狀態(tài)、性格等的形容詞，如：
happy， glad，lucky， frtunate， surprised， angry，anxius， cruel， clever， frightened，shcked， srry， eager， prud，disappinted， flish， impatient，unwise， naughty等。如：
We were surprised t see him. 我們真想不到會(huì)見(jiàn)到他。We are prud t be yung peple f new China. 作為新中國(guó)的青年，我們感到很驕傲。Yu were flish t act like that. 你那樣做很愚蠢。

In 1921 Einstein wn the Nbel Prize, and was hnred in Germany until the rise f Nazism when he was driven frm Germany because he was a Jew. 1921年愛(ài)因斯坦獲得了諾貝爾獎(jiǎng)，他在德國(guó)很受尊敬。納粹上臺(tái)后由于他是猶太人而被趕出了德國(guó)。

DD鳥(niǎo)是一種不會(huì)飛的鳥(niǎo)，僅產(chǎn)于毛里求斯肥。擁有肥胖的身子和巨大的嘴。 16世紀(jì)后期，歐洲殖民者來(lái)到了毛里求斯。不會(huì)飛又跑不快的DD鳥(niǎo)很快成為歐洲人來(lái)到島上后主要的食物來(lái)源。人們開(kāi)始大量的濫捕濫殺可憐的DD鳥(niǎo)，有時(shí)每天可以捕殺到幾千只到上萬(wàn)只。 由于過(guò)度的捕殺,很快島上DD鳥(niǎo)便得越來(lái)越少。1681年，最后一只DD鳥(niǎo)被殘忍的殺害后，從此，地球上再也見(jiàn)不到這種東西了，除非是在博物館的圖片中。
