房地产资产的物业类型主要包括居住物业、商用物业、工业物业和特殊物业。哪一种物业属于什么类型也不是一成不变的。比如，居住小区的车库，如用于业主自己停放私家车，就属于居住物业；如用于业主向外出租，收取租金，就属于商业物业。 ( )

     Go ahead, talk to your dog.

     As many a dog owner will prove, our furry friends are listening.Now, for the doubters, there is

scientific proof that they understand much of what they hear.A border collie called Rico can fetch at

least 200 objects by name, researchers in Germany say.The dog also appears to learn words for new

objects as easily as a 3yearold child would.Its wordlearning skill is as good as that of a parrot or

chimpanzee.

     In one experiment, the researchers took all 200 items that Rico is supposed to know and divided

them randomly into 20 sets of 10 objects each.The dog waited with one of his owners in one room,

while an experimenter put a set of 10 objects into another room.Then, the owner told the dog to fetch

one of the items.  The dog had to go to the other room and bring the object back

     In four trials, Rico got 37 out of 40 commands right.Because the dog couldn't see anyone to get visual

clues about what to bring back, the scientists concluded that he must understand the meanings of certain

words.

     In another experiment, the scientists took one toy that Rico had never seen before and put it in a

room with seven toys whose names he already knew.The dog's owner then told him to fetch the object,

using a word Rico had never heard.

     In 7 out of 10 trials, Rico picked the right object, suggesting that he figured out the answer by

process of elimination.A month later, he remembered half of the new names, which further impressed the

researchers.

     Rico is probably smarter than the average dog, the scientists say.For one thing, he's a border collie,

a breed known for its mental abilities.In addition, the 9yearold dog has been trained to retrieve toys by

their names since he was 9 months old.

     It's hard to know if all dogs understand at least some of the words we say.Even if they do, they can't

talk back.Still, it wouldn't hurt to sweettalk your pup every now and then.You might just get a big, wet

kiss in return!

某大学基础法律课上同学们对法的渊源问题进行了讨论。①甲同学说某贫困县人大常委会作出的具有规范性的决定属于法的渊源；②乙同学说《民法通则》第6条规定“民事活动必须遵守法律，法律没有规定的，应当遵守国家政策”，所以国家政策都是当代中国法的正式渊源之一；③某大家族有这样一条习惯：凡丧失劳动力又没有生活来源的成员应当在分遗产时予以照顾，但未参加家族祭祀活动的除外，我国《继承法》第13条第2款规定“对生活有特殊困难的缺乏劳动能力的继承人，分配遗产时，应当予以照顾”，因此丙同学认为习惯也是我国法的正式渊源；④丁同学认为虽然我国最高人民法院每年都会集结出版一些典型案例供各级法院参考，但我国当代并不采用判例法制度，因此判例不是我国法的正式渊源。关于同学们的看法哪些是错误的( )

A．①②

B．③④
