I wouldnt hang up，” I said. “I should have told you, Mama. But when we talk, you just keep telling me what I should do. You read all those pamphlets (手冊) on how to talk to kids,_but all you do is talk. You dont listen to me. Because youre my mother,_you think you have all the answers. But sometimes I dont need answers. I just want someone to listen.” I stared at the howtotalktoyourkids pamphlets on my nightstand (床頭柜)．“ Im listening，” I whispered.

I looked_back_at my husband and said to him, “Maybe it wasnt such a wrong number.” 第五步：潤色升級 1．用with復合結(jié)構(gòu)改寫要點6。 She_was_sleeping_with_a_smile_on_her_face. 2．用同源賓語結(jié)構(gòu)改寫要點7。 Maybe_she_was_dreaming_a_nice_dream. 3．用分詞作狀語改寫要點11。 I_stood_there_for_a_while,_thinking_about_the_whole_thing. 第六步：復查定稿 Paragraph 1： I went to my 16yearold daughters room.My_husband came from behind. My_daughter was sleeping quietly. I looked at my husband, and he was also looking at me. “We have to learn to listen，” I said to him. He studied me for a second, and then asked, “Do you think she will ever know that she dialed the wrong number？” Paragraph 2： I looked at our sleeping daughter. She was sleeping with a smile on her face. Maybe she was dreaming a nice dream. She didnt know what had happened. She didnt know her mother had learned something important just now. Its necessary to tell children what to do, but its more important to listen to them. I stood there for a while, thinking about the whole thing. Then I looked back at my husband and said to him, “Maybe it wasnt such a wrong number.” 一、復現(xiàn)單元考點——增強備考信心 Ⅰ.高考中的語法填空 1．(2018江蘇高考)Try to understand whats actually happening instead of acting on the assumption (assume) youve made. 2．(2017北京高考)Jim has_retired (retire), but he still remembers the happy time spent with his students. 3．(2016浙江高考)In many ways, the education system in the US is not very different (differ) from that in the UK. 4．(2015全國卷Ⅱ)As natural architects, the Pueblo Indians figured out exactly (exact) how thick the adobe walls needed to be to make the cycle work on most days. 5．(2015湖北高考)He gave himself a new name to hide his identity (identical) when he went to carry out the secret task. 6．(2013廣東高考)“That would be a very reasonable (reason)thing to do in a big city, but it could destroy a small village like ours，” Nick said.

By December, the Chinese Academy of Sciences had created two clone macaques (獼猴) named “Zhong Zhong” and “Hua Hua” by nuclear transfer (核移植) of body cells — any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996. [2]Tetra, a monkey born in 1999, is the worlds first evercloned monkey, but it was done using a simpler method called embryo splitting, and cannot be genetically modified (改造) to suit experimental needs, said Pu Muming, a leading researcher at the Chinese Academy of Sciences. Cloning a monkey using body cells has been a worldclass challenge because it is a primate (靈長類) that shares its genetic makeup with humans, he said. [3]For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, Pu said. [4]“By cloning monkeys using body cells, we can reproduce a large number of genetically identical monkeys in a short amount of tim
