• Read the following passage and mark the letter A, B, C, or 0 on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

  Every summer, when the results of university entrance exam come out, many newspaper stories are published about students who are top-scorers across the country. Most portray students as hard-working, studious, smart and, generally, from low-income families. They are often considered heroes or heroines by their families, communes, villages and communities, And they symbolise the efforts made to lift them, and their relatives, out of poverty. The students are often too poor to attend any extra-classes, which make their achievements more illustrious and more newsworthy. While everyone should applaud the students for their admirable efforts, putting too much emphasis on success generates some difficult questions.

  If other students look up to them as models, of course it's great. However, in a way, it contributes to society's attitude that getting into university is the only way to succeed. For those who fail, their lives are over. It should be noted that about 1.3 million high school students take part in the annual university entrance exams and only about 300,000 of them pass. What's about the hundreds of thousands who fail? Should we demand more stories about those who fail the exam but succeed in life or about those who quit university education at some level and do something else unconventional?

  "I personally think that it's not about you scoring top in an entrance exam or get even into Harvard. It's about what you do for the rest of your life," said Tran Nguyen Le Van, 29. He is the founder of a website, vexere.com, that passengers can use to book bus tickets online and receive tickets via SMS. His business also arranges online tickets via mobile phones and email. Van dropped out of his MBA at the Thunderbird School of Global Management in Arizona in the United States. His story has caught the attention of many newspapers and he believes more coverage should be given to the youngsters who can be role-models in the start-up community. Getting into university, even with honours, is just the beginning. We applaud them and their efforts and obviously that can give them motivation to do better in life. However, success requires more than just scores," Van said. Van once told a newspaper that his inspiration also came from among the world's most famous drop-outs, such as Mark Zuckerberg of Facebook or Bill Gates who also dropped out of Harvard University.

  Alarming statistics about unemployment continues to plague us. As many as 162,000 people with some kind of degree cannot find work, according to Labour Ministry's statistics this month. An emphasis on getting into university does not inspire students who want to try alternative options. At the same time, the Ministry of Education and Training is still pondering on how to reform our exam system, which emphasises theories, but offers little to develop critical thinking or practice. Vu Thi Phuong Anh, former head of the Centre for Education Testing and Quality Assessment at Vietnam National University in Ho Chi Minh City said the media should also monitor student successes after graduation. She agreed there were many success stories about young people, but added that it was imbalanced if students taking unconventional paths were not also encouraged.

  Vietnam is, more than ever, in desperate need of those who think outside the box. Time for us to recognise talent, no matter where it comes from or how.

  The word "them" in paragraph 3 refers to__________.

• Vietnamese parents normally do not let their children make a decision___________their own future career.

• Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  A generation gap in the workplace can make workers both young and old feel inferior, as well as hamper productivity and teamwork. Differences between generations can be seen in work ethics, habits and communication styles. Younger workers might fear not being taken seriously by their older colleagues, while older workers might fear that their experience is not valued but replaced by workers with knowledge of more current technology. However, members of each generation can close the gap between them if they're willing to meet one another halfway.

  Older workers can show respect to the younger set by asking for their opinions and recognizing their contributions to the workplace as valid, or complimenting them on a job well done. Younger workers can show their elders respect by asking for advice on how to manage a situation with work, based on the older worker's many years of experience. It's important for both entry- and senior-level workers to see each other as equals, regardless of the type of position in which they work. No one wants to feel inferior or irrelevant just because of their age. Rather, a generation gap at work can be a learning opportunity.

  Workers can also put themselves in their colleagues' shoes to determine what might be bothering them about their generational age difference. If a person is much older than another, perhaps it is bitterness about fewer job opportunities, or fear that a younger worker might seem more relevant and edge him out of his job. If workers open their minds to understand where co-workers are coming from, it can help ease any tension between them and appreciate each other's work contributions.

  If age seems to be a problem for someone at the workplace, it can be helpful to do the very opposite of what a co-worker might expect from someone of a different age set due to stereotypes. For example, if a worker is considerably younger such as right out of college, she can share researched information to indicate that she knows what she's doing, or show curiosity instead of upset to indicate emotional maturity if the person makes a disparaging remark about her youth. Older workers can maintain an enthusiastic attitude about work instead of showing boredom or bitterness from past experiences.

  Workers can, moreover, directly address the concern of age differences at work with the colleague at odds with them by asking the person for constructive advice on how to handle the issue. For example, older workers who are unfamiliar with new software that younger colleagues understand might acknowledge to them that they did the same tasks differently in years past but show interest in learning the program to keep up with modern technology. Learning to speak their technological language can make them feel more connected. Likewise, a younger worker can admit to being green on the work scene, but eager to gain experience by learning from senior colleagues.

  The word “acknowledge” is closest in meaning to______.
