1 . “Your password has expired,” a message said on my screen, with instructions for changing it. Coming up with a new code doesn’t seem like a big deal, unless you work at my company, where we have to change it monthly, using at least one uppercase character, one lowercase character, one symbol, and one number. Oh, the whole password can’t be fewer than eight characters. And I can’t use any of the same passwords I’ve used in the past three months.

2 . “When you leave work you’re usually an expert in whatever you did. Then you start something new and everyone is younger than you, they know more than you do, they’re probably better at risk-taking, I think they’re better educated. It’s easy to feel intimidated (胆怯的). But remember you have skills that you’ll be able to build on.” Allison says, “Art gives me a different place in the world. When I’m making staff, and I’m hard at it, I feel very joyful.”

Which word can best describe Allison Barnes according to the last paragraph?

3 . But actually, hacking is just an activity. What separates any activity from a crime is, very often. permission. People are free to drive, but they do not have permission to drive 150 miles per hour, which is a criminal offense. Since a driver is just a driver. why must a hacker be a criminal? Someone who engages in the illegal use of hacking should not be called a ‘bad hacker’ but a ‘cybercriminal’. Contrary to popular belief, most hackers like Mike’s father undoubtedly play an important role in keeping companies and people safe.

4 . I am Peter Hodes, a volunteer stem cell courier. Since March 2012, I've done 89 trips — of those, 51 have been abroad. I have 42 hours to carry stem cells (干细胞) in my little box because I've got two ice packs and that's how long they last. In all, from the time the stem cells are harvested from a donor (捐献者) to the time they can be implanted in the patient, we've got 72 hours at most. So I am always conscious of time.

Which of the following can replace the underlined word “courier” in Paragraph 1?

8 . All my life, for three decades now, I've gone to work early each day with a spring in my step. Occasionally, I meet my former students. Their obvious love for me and fond memories of our time together are my rewards. When I meet others who thirst for superpowers, like the brand new teacher struggling to perfect her skills with a brave face on, or the one in a remote, rural school travelling 70 kilometers each day just for his pupils, I feel proud to belong to the same group.

9 . “A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music when you have to go back to the right spot.” Mr Titterton explained.

Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.

10 . After connecting with the opportunity and successfully completing the application process, Kajal got to work. Her role involved reviewing 44 in-depth applications from potential candidates across Latin America and the Caribbean for a four-week fellowship in the U.S.. She was responsible for describing the business ideas presented by these candidates, assessing the social impact of their businesses, and determining the strength of candidates to carry out their plans. With almost 4,000 applicants in 2017, volunteers like Kajal were important members of the YLAI team.
