【題目】通過學(xué)習(xí),我們了解了地球的形狀和大小。下列現(xiàn)象或?qū)嶒?yàn),不能證明地球是球體的是( )
A. 麥哲倫環(huán)球航行 B. 日食 C. 月食 D. 海平面上船只的出沒
【答案】B
【解析】
能證明地球形狀是球體的例子很多:站得高,才能看得遠(yuǎn)、麥哲倫環(huán)球航行、人造衛(wèi)星拍攝的地球照片、遠(yuǎn)處駛來的帆船總是先看到桅桿,再看到船身、月食尤其是月環(huán)食時(shí),可以看到地球擋在太陽和月球之間的影子,月食就是地球在月亮上的投影,從形狀可以證明地球是圓的等。
地球衛(wèi)星照片、麥哲倫船隊(duì)環(huán)球航行,站在海邊看遠(yuǎn)處駛來的帆船總是先看到桅桿,再看到船身、能證明地球是個(gè)球體。月食是地球在月亮上的投影,從形狀可以證明地球是圓的。日食月亮擋住了太陽照射到地球上的光。不能證明地球是一個(gè)球體。故選B。

【題目】依次填入下面文段橫線處的語句,銜接最恰當(dāng)?shù)囊豁?xiàng)是( )
好的傳播,一定要有好的故事。
①一個(gè)故事如果只停留在反映情感的層面,充其量只能算是有內(nèi)容。
②如何以人為本?最重要的是與人相聯(lián)系。
③好的故事內(nèi)容必須具備積極向上的價(jià)值觀,而且能夠發(fā)揮引領(lǐng)作用。也就是說,故事內(nèi)容得與真、善、美息息相通。
④以人為本是檢驗(yàn)一個(gè)故事生命力的主要標(biāo)準(zhǔn)。
⑤在信息過量時(shí)代,有內(nèi)容的故事未必能取得良好的國際傳播效果。
⑥正如馮友蘭所說:“人類所有之真、善、美,歷史多與以相當(dāng)?shù)牡匚。其未得相?dāng)?shù)牡匚徽,則多其不真真、不真善、不真美者也!
