Thats right. 说对了。 请注意Thats right, Thats all right, All right之间的区别。 Thats right意为“对的；答对了”，表示某人的观点正确，或是某人的回答与答案一致； Thats all right意为“没关系；不客气”，用于Sorry或Thank you的回答； All right与OK意思相近，意为“好的；好吧”，用于接受别人请求或建议等。2. Someone left these puppies and their mother in the street. 有人把这些小狗和他们的妈妈丢弃在街头。 句中的left是动词leave的过去式，在本例中leave意为“遗弃；丢弃”。与之类似的用法有 Some people leave rubbish on the beach. 有人在海南上乱扔垃圾。3. They had no food or water. 它们没有吃的，也没有水喝。 no相当于not any。 本句可改写为：They didnt have any food or water. or用于否定句中连接并列成分，表示“和；与”之意。如： There isnt any air or water on the moon. 月球上既没有空气也没有水。 【注意】肯定句中并列连词用and。在把含有and的肯定句改为否定句时，要记得吧连词and改为or。如：The students sang and danced in the park yesterday. 昨天学生们在公园里又唱又跳。4. I found them and took them to the SPCA. 我发现了它们，并把它们带到了SPCA。 take sb./sth. to some place是“把带去（某地）”的意思，其反义短语为bring sb./sth. to some place “把带来（某地）”。试比较如下： Dont forget to bring your textbook to school tomorrow. 明天别忘了把课本带到学校来。 Dad took us to the museum last Friday. 爸爸上周五带我们去了博物馆。5. Would you like to keep one as your pet? 你们愿意饲养一只（小狗）当宠物吗？ 本句中的keep是“饲养，养”的意思，与raise意思相近。 6. How to take care of your new puppy? 如何照料你家新来的小狗 take care of是“照顾；照料”的意思，后接名词或名词短语、代词或动词的ing形式，如： You should take care of your health. 你应该注意自己的健康状况。（接名词） Hes old enough to take care of himself. 他大了，能照顾自己了。 （接代词） 7. Give him/her a basket to sleep in. 给他/她一个睡觉用的篮子。 在这个句子中，to sleep in是用来补充说明a basket的用途。 在课文中还有下面这个句子： The SPCA officer has given them a booklet to read. SPCA的官员给了他们一本小册子要他们阅读一下。 其中to read也是补充说明a booklet的作用。 8. Take him/her to a park or the countryside for a walk every day. 每天都带他/她去公园或乡下散步。 take.for a walk 意为“带去散步”。如： My grandparents always took me for a walk in the estate garden after dinner when I was in kindergarten. 上幼儿园的时候，祖父母常常在晚饭后带我在小区花园里散步。9. Well need to buy a lot of things for our puppies. 我们需要给我们的小狗买很多东西。 本例中的need为实义动词，意为“需要，必须”。need to do sth. 意为“需要做某事”。当need做实义动词时，有时态和人称的变化，其后接to的不定式。如： I need to do my home work now. 我现在就要做我的作业。 它的否定形式为not need to。如： I dont need to do my homework now. 我现在不必做作业。10. SPCA officers save animals from danger and take them to the SPCA. 爱护动物协会的官员们把它们从危险中解救出来，并把它们带回了爱护动物协会。 save.from.是“挽救以免与”的意思。 例题：I. Choose the best answer. （选择正确的答案）( ) 1.
