The bank clerk nodded and I sat in front of him. He was busy filling up entries in his register. I put my form and booklet in front of him.After waiting for a few more minutes, in which I showed all signs of being impatient, I asked him if my work was done. He shouted, "Nothing is done, and it will take time ! " Just then I saw his morning cup of tea, which had been lying there for the last ten minutes, untoucheD.The tea had turned almost cold while he was doing his work.Suddenly I felt what this man must be feeling when customers like me come always in a hurry to get their work done. We do not even feel the need to thank them for being there. So I told him, "Sir, please have your teA.I am not in a hurry. " This man suddenly looked up at me and for the first time we had eye contact.I saw a different person there, who was as hard-pressed for time as I always am. _ . I felt that he was also missing the small things in life like a hot cup of tea or lying in a warm bed for a few more minutes like me.He gave me a rare smile and said, "It is an everyday affair with me; you are not in a hurry but somebody else will be. He really touched my heart with his wise words. I felt that all this time I thought of him as someone who was there for my convenience, but today I suddenly felt a strange communion with him. I vowed to be friendly with people who help me with my work and be thankful that they are there for me. Question: What can we learn about the bank clerk? Options: A: He hated to work on a holiday .

These were the words of David Baltimore of the California Institute of Technology,on December 1st,when he opened a threeday meeting in Washington to discuss the morality and use of human gene editing.Dr Baltimore is an old hand at these sorts of discussions,for he was also a participant in the Asilomar conference,in 1975,which brought scientists together to discuss a safe way of using the thennew technology of recombinant DNA,and whose recommendations influenced a generation of biotechnology researchers. Four decades on,the need for a similar sort of _ has arisen.The International Summit on Human Gene Editing has been held by the national scientific academies of three countries--America,Britain and China.They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line,something Dr Baltimore described as a deep and troubling question.Like those of Asilomar,the conclusions of this meeting will not be binding.But the hope is that,again like Asilomar,a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves,rather than having politicians and civil servants do it for them.The meeting is being held against a backdrop of rapid scientific advance.Since 2012 research into a new,easytouse editing tool called CRISPRCas9 has blossomed.This technique involves a piece of RNA (a chemical messenger,which can be used to recognise a target section of DNA) and an enzyme called a nuclease that can snip unwanted genes out and paste new ones in. Public interest was aroused in April,when Chinese scientists announced they had edited genes in nonviable human embryos,and again in November when British researchers said they had successfully treated a oneyearold girl who had leukaemia ,using geneedited Tcells.Tcells are part of the immune system that attack,among other things,tumour... Question: Which of the following is TRUE about CRISPRCas9? Options: A: It has fewer side effects. B: It can modify human gene. C: It can protect immune system. D: It has less commercial potential.

Read the article and select the best answer. Article: In prefix = st1 /America, drivers' education is part of high school. Every student in his or her second year of high school is required to take a course in drivers' education. However, unlike other courses, it isn't given during the regular school year. Instead, it is a summer course. The course is divided into two parts: class time for learning the laws and regulations, and driving time for practice. The students study the basic traffic laws they must know to pass the written driving test, which is given to anyone who wants to get a driver's license. Driving time is a chance for the students to sit behind the steering wheel and practice all kinds of skills that are required to drive a car. Each student is required to drive for a total of six hours. The students are divided into groups of four. The students and the instructor go out driving for two hours. Thus, each student gets half an hour of driving time per outing. The instructor and the "driver" sit in the front seats and the other three students sit in the back. The cars for drivers' education are different from other ears. In this kind of car there are two sets of brakes, one on the driver's side and the other on the instructor; s side. Thus, if the student driver runs into difficulties, the instructor can take over. This kind of car also has another special feature. On the rear window of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should be more careful because the student driver isn't very experienced. After the student has passed the drivers' education course and reached the proper age to drive, they can go to a designated state office to take the driving test, which is made up of an eye examination, a written test, and a road test. The student must pass all the three tests in order to get a driver's license. If the student does well in the drivers' education class, he or she will have no problem passing the test with flying color1s and getting licensed. Question: We can infer that the students are required to_in their whole driving practice. Options: A: go out driving for twelve times B: spend at least six hours driving C: drive for two hours D: get half an hour driving each time
