课时作业(六)
5．下列分子既不存在sp σ键，也不存在pp π键的是( D )
A．HCl
B．HF
C．SO2
D．SCl2

的，s和p轨道以“头碰头”重叠可形成sp σ键，p轨道之间以“肩并
肩”重叠可形成pp π键。HCl分子中存在sp σ键，故A错误；HF分

课时分层作业(六)Ⅰ.阅读理解AWhen most high school students complain about having to wa ke up extra early，they're usually referring to a swim practice before class or the lastminute study before a test.But that was never the case for Corey Patrick，who woke up at 4：30 every morning last year in order to arrive on time at Tarran t High School in .Patrick had attended Tarrant City Schools since his fourth gra de，but things got difficult when his family moved to a town 14 mil es away.Even though his family didn't have any forms of trans portation，Patrick didn't want to miss out on his senior year with friends ，so he woke up at 4：30 every morning in order to make it to a 5：41 a．m.bus that would help him get to Tarrant on time.And j ust as he had done every other school day of the year，Patrick got up one morning to start the journey from his hometo his high school; the only obvious difference that morning w as that he was wearing his graduation gown (毕业礼服)，which made that day's bus driver，DeJuanna Beasley，take some photos of him.She then shared them online with th ese words，“You tell me this isn't determination.He got on my bus to go to his graduation，and no one was with him.Sometimes it's all in what you want out of life.I was so proud of this young man.”That was soon shared by many people online，and it caught the attention of radio host Rickey Smiley，who surprised Patrick by giving him a car later.Smiley confirm ed that he would make sure that Patrick received help with ge tting his driver's license.A GoFundMe was also created for Pa trick，which has raised over $20，000.And Patrick has got a scholarship (奖学金) to Jacksonville University，where he plans to study computer science.【语篇解读】语篇类型是记叙文，主题语境是人物故事。
