My family and I never talked about school as the ticket to a future. I was in the classrooms, but I wasn’t there to learn to write, read or even speak. When it was my turn to read, I wanted to hide. I was 13 years old, but I already hated being who I was.
I had an English teacher, Mr. Creech, who knew I couldn’t read. In one of my first lessons the teacher said that anyone who had a reading age below six had to stand up. I felt so embarrassed. But at the same time, it made me realize that I needed to change the situation. I was determined it wouldn’t happen again. Later that day, Mr. Creech encouraged me and promised he would try his best to help me learn to read. From then on, I never gave up practicing reading.
Now I was 41 years old. One day, I planned to fly back to Texas to visit my friends and family. On my way from the airport, I saw Mr. Creech buying himself a drink. I rushed over and reached into my pocket to pay for him. “Do I know you?” he asked. “Yes, sir, you do know me,” I answered excitedly. “My name is Anthony Hamilton. You taught me English.” The look on his face told me that he remembered the boy he’d once encouraged.
“I’m so glad I had a chance to see you,” I said. “And Mr. Creech, I have great news to share.” I told him I had learned to read. But that wasn’t all. I had become a published author and an active speaker. “The next time you get another Anthony Hamilton in your classroom, please encourage him to read as well,” I added.
The experts say what once worried me has a name: dyslexia (诵读困难症). But I can tell you it was a lack of desire for education.

4.What can we infer from the passage?

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components,” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically, it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
1.Which of the following statements was the difficulty engineers met while making the robotic fly?
A.They did not have sufficient fund.
B.No ready-made components were available.
C.There was no model in their mind.
D.It was hard for them to assemble the components.
2.What can be inferred from paragraphs 3 and 4?
A.The robotic fly has been put into wide application.
B.The robotic fly consists of a flight device and a control system.
C.Information from many sources can be collected by the robotic fly.
D.The robotic fly can just fly in limited areas at present.
3.Which of the following can be learned from the passage?
A.Wood’s design can replace animals in some experiments.
B.Animals are not allowed in biological experiments.
C.The robotic flyer is designed to learn about insects.
D.There used to be few ways to study how insects fly.

The joy of absence
How some companies fight the curse of presenteeism (出勤主义)?
RONALD REAGAN famously joked that “it’s true hard work never killed anybody, but I figure, why take the chance?” Beyond a certain level, extra effort seems to be self-defeating. Studies suggest that, after around 50 hours a week, employee productivity declines sharply.
But that doesn’t stop some managers from demanding that workers stay chained to their desk for long periods. Jack Ma, the founder of Alibaba, the Chinese e-commerce group, recently praised the 996 model, where employees work from 9a.m. to 9p.m., six days a week, as a “great opportunity”. Yet presenteeism is the curse of the modern office worker.
There will be days when you do not have much to do; perhaps because you are waiting for someone else in a different department, or a different company, to respond to a request. As the clock ticks past 5p.m., there may be no purpose in staying at your desk. But you can see your boss hard at work and, more importantly, they can see you. So you make an effort to look busy.
The consequence is often wasted effort. Rather than work hard, you slave to make bosses think that you are. But presenteeism has more serious consequences. As well as reduced productivity, this can mean greater medical expenses for the employer. According to a study in the Journal of Occupation and Environmental Medicine, these costs can be six times higher for employers than the costs of absenteeism among workers.
None of this is to say that employers are not called to expect workers to be in the office for a proper period of time. Surely there will be a need for some (preferably short) meetings. Dealing with colleagues face-to-face creates a feeling of togetherness, allows for a useful exchange of ideas and enables workers to have a better sense of their mutual needs.
Turning an office into a prison, with inmates (囚犯) allowed home for the evenings, does nothing for creativity that is increasingly demanded of office workers as routine tasks are automated. To be productive you need presence of mind, not being present in the flesh.
