甲型血友病（HA）是由于凝血因子Ⅷ（FⅧ）基因缺陷引起的一种伴X染色体遗传病，下图为一甲型血友病患者家庭经遗传咨询后得到的系谱图。FVI基因上的不同区段有特定的酶切位点，通过酶切后片段的种类可以初步判断FVM基因是否异常。基因检测可诊断疾病，也可用于子代遗传病风险的预测，为优生提供更好保障。下表为对该家族部分成员的进行基因诊断时得到的结果，对Ⅱ-2和Ⅲ-1的两条X染色体以及Ⅲ-2的X染色体上的FVI基因区段分别进行了酶切，酶Once upon a time, there was a scholar who wanted to gain more knowledge each day even though he had already gained enough knowledge. One day, he came to visit a saint and wanted to be his student. The saint provided some tea. He slowly filled the scholar’s cup: the cup was full, yet he kept pouring and pouring. The scholar burst out, “Stop! You can’t add anything to something that’s already full!” The saint set down the teapot and replied, “Exactly.”Whether it’s the silence between notes in music, or some open time in your schedule, you need space to act effectively. Yet most of us, myself included, tend to stuff as much as possible into whatever room is available-closets, schedules, budgets, relationships, and even the mind itself.However, some people know how to avoid overstuffing their life. For example, in Australia, it seemed that most people there operated at about 85% of their capacity（能力），unlike Americans pushing as close to 100% as possible. So when you run into Australians you know in the street, they have time to hang out and talk with you.Remember the cup: its value is in the space, the emptiness it holds. How to empty your “cup”?Be mindful of the element of space, openness , and emptiness  in your life. This includes room in a drawer, the volume of air in a kitchen, and open-mindedness in a friend. Sometimes you’re just stuck with a big bucket of tasks yet to do. But at least empty the bucket faster than you fill it with new tasks. Put some space between finishing one thing and staring another. For example, after sending one email, take a breath before replying to another one. Drop the stuff you can no longer afford to lug around. At sea level, you can run with a brick in your backpack, but if you’re hiking on a mountain, that brick has got to go.1.By pouring water into the cup, the saint most probably wanted the scholar to know that     .A.he should pay attention to detailsB.he should keep learning every dayC.he had already gained enough knowledgeD.he should be very careful in order to succeed2.We learn that compared to Americans, Australians      .A.work much harderB.know less about their capacityC.spare more time for themselvesD.spend less time with their friends3.The underlined word“lug”in the last paragraph probably means“     ”.A.reachB.carryC.seeD.show4.What’s  the structure of the passage?A.Example →advice→ conclusion →story.B.Topic→ example →advice→ story.C.Story→topic →example→advice.D.Reason →topic →advice →example.5.What would be the best title for the passage?A.The art of life.B.Value every minuteC.The art of drinking teaD.Empty your“cup”at times
