It takes sb. some time to do sth.為固定句型,意為“花費某人一些時間做某事”,所以用to eat。7. 此處表示熊貓吃飽后喜歡散步“或者”攀爬,用or表示選擇。8. spend +時間+(in) doing sth.為固定搭配,意為“花費時間做某事”,所以用sleeping。9. 后句“人們砍伐太多竹子”是熊貓?zhí)幱谖kU的原因,用because引導(dǎo)原因狀語從句。10. be friendly to sb.為固定短語,意為“對某人友好”,所以用friendly。七、閱讀理解。【答案】1. A。解析:文章未提及加拿大的Dogs' Day,在中國Dogs' Day被人們看作是重要的一天,答案可能是出題失誤,推測是想考查中國的情況,所以選A。2. D。解析:根據(jù)“In Indonesia, May 7th is Monkeys’ Day. People give nice food to monkeys. They also play music for them.”可知在印度尼西亞的猴子節(jié),人們給猴子美味的食物,還為它們演奏音樂,所以選D。3. B。解析:根據(jù)“We live in the same world as animals. We should make friends with them.”可知我們和動物生活在同一個世界,所以應(yīng)該善待它們,選B。4. B。解析:文章主要介紹了中國的狗狗節(jié)、比利時一個城鎮(zhèn)的貓咪節(jié)和印度尼西亞的猴子節(jié),所以是關(guān)于一些動物節(jié)日的,選B。【一題多練】5. Many countries have animal festivals to show their love for animals.6.
