research has found a new recipe of succ ess．According to the study，if the cat is adopted before the dog，and if they are introduced when still young （less than 6 months for cats，a year for dogs），it is highly probable that the two pets will get along ．Two-thirds of the ho mes interviewed reported a positive relationship between their cat and dog．However，it wasn’t all sweetness and��light．There was a reported coldness between the cat and dog in 25% of the homes，while aggression and fighting were observed in 10% of the homes．One reason for this is probably that some of their body signals were just opposite．For exam ple，when a cat turns its head away it signals aggression，while a dog doing the same signals submission．In homes with cats and dogs living peacefully，researchers observed a surprising behaviour．They are learning how to talk each other’s language．It is a surprise that cats can learn how to talk’dog’，and dogs can learn how to talk’Cat’．What’s interesting is that both cats and dogs have appeared to develop their intelligence．They can learn to read each other’s body signals，suggesting that the two may have more in common than we previously suspected．O nce familiar with each other’s presence and body language，cats and dogs can play together，greet each other nose to nose，and enjoy sleeping together in the sofa．They can easily share the same water bowl and in some cases groom（梳理）each other．The significance of this research on cats and dogs may go beyond pets–to people who don’t get along，including neighbors，colleagues at work，and even world superpowers．If cats and dogs can learn to get along，surely people have a good chance．9．The underlined word swimmingly in paragraph 1 is closest in meaning to_______ _．A．earlyB．sweetlyC．quicklyD．smoothly10．Some cats and dogs

Moments with Our ParentsThere was something in an elderly woman’s behavior that caught my eye．Unsureof her steps，the woman moved slowly，along with a younger woman who I guessed was her daughter．The

younger woman，who was still tapping her foot at the front of the store．“Is that your mom？”I asked．I had expected her to tell me it was none of my business．But she rolled hereyes and said，“Yeah．”There

travel是并列表语，都是动名词作表语．55．unless改为until 考查连词．根据句意：我让他在外面等到我完成工作．用连词until．56．arrive改为arrived 考查动词时态．全文讲述的是过去的事情，要用一般过去时态．57．eye改为eyes 考查名词复数．人的眼睛有两只，要用复数形式．58．去掉for 考查词语用法．thank是及物动词，后接宾语时不需要介词．59．nothing改为something 考查不定代词．根据句意：如果我的儿子经历相似的事情．用不定代词something．60．nicely改为nice 考查形容词．be动词后用形容词作表语．五、书面表达My Views on Sharing bikes Presently，in big cities like Shanghai and
