【题目】某生物兴趣小组对学校草坪的某种雌雄同花的植物进行了遗传学研究，发现该种植物的花色有红色和白色两种。他们查阅资料后发现，该对性状受一对遗传因子控制。为了对该对性状做进一步研究，该小组随机取红花和白花植株各60株均分为三组进行杂交实验，结果如表所示：
组别 | 杂交方案 | 杂交结果 |
A组 | 红花×红花 | 红花︰白花=14︰1 |
B组 | 红花×白花 | 红花︰白花=7︰1 |
C组 | 白花×白花 | 全为白花 |
（1）根据 组结果，可以判断 色为显性．
（2）试解释A组结果没有出现3︰1性状分离比的原因 ．
（3）B组亲本的红花中，纯合子与杂合子的比例为 ．

【题目】根据短文内容，从下框的A—F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余选项。
A. Be ready for the questions to be asked.
B. Take copies of your resume to the interview.
C. Think about your education and the skills you have learned.
D. Good preparation before the interview.
E. Come to the interview with personal information.
F. Try to get to know more about the company.
【1】Preparation is a big part of the interview process. You will, or you should, spend more time getting ready for the interview than you will at the interview itself. This preparation includes getting to know more about the company and the position you are applying for, and preparing yourself to explain how your valuable qualities make you the best person for the position. And of course, there is the time it takes to make yourself presentable. Job interview can be a stressful situation for many people. The best way to help relieve this stress is to hold a positive attitude and be well prepared. Consider the following tips as you prepare for your interview.
【2】Think of the answers you want to give. Although you will never completely know in advance every question they will ask you, there are questions that get asked in almost every interview. Learn what they are and try to predict what the others might be. Interview questions are usually sourced from the job posting. If they are looking for a particular skill set, make sure you can explain how you will meet that expectation.
【3】Do your best to get information about the company before the interview. Do some research, such as using their website, scanning through annual reports if they publish one, being familiar with the project they are now working on. This will help you to present your answers in the context of what their core business is about.
【4】Most job postings have a list of core duties or responsibilities as well as what qualifications are required. Study these well and prepare your answers accordingly. Think about what education and training you have had and what work experiences you have done that makes you the ideal person for the position. Be thorough in your self-assessment, think broadly about all you have learned and experienced. You may surprise yourself with what skills you have acquired previously.
【5】In most cases, the interviewer will have your resume already, but it never hurts to have some back-up copies just in case. And be sure they are the most current and relevant resume for the position.

阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
People around the world are remembering Nelson Mandela, South Africa’s first black president. He died Thursday at the age of 95.
South African President Jacob Zuma said, ＂The nation has lost its greatest son, and our people have lost a father. ＂
Mandela had been in poor health for several years. He was repeatedly treated in hospital, most recently for a lung infection. He became infected with tuberculosis(肺结核) many years ago while in prison.
Nelson Mandela was the main leader in efforts to end white minority rule in South Africa. He spent 27 years in prison for his part in fighting apartheid(种族隔离)—the nation’s policy of discrimination(歧视)against blacks.

Frederick W. de Klerk was South Africa’s last apartheid leader. He freed Mandela from prison in 1990. Later, the two men won the Nobel Peace Prize.

He said their relationship was, in his words, ＂often stormy＂, but he said they were＂always able to come together at critical(关键的)moments. ＂
In the United States, President Barack Obama called Mandela an influential, brave and profoundly good human being.

My very first political action — the first thing I ever did
