在科学技术的帮助下，我们人类现在过着比以往更幸福的生活。以电脑发明为例，它不仅帮助我们解决数学难题来节约时间，而且你也能把材料或信息输进电脑通过网络与你的生意伙伴进行交流。另外它可以在程序员的操作下取代我们处理很危险的工作。在某种程度上，他们的优势超过人类的优势，这就是为什么人们创造一些有人工智能的机器人来帮助我们人类的原因。

然而，一些人担忧在高科技的滥用中会出现危险的问题。就我个人而言，我不同意这点。不管怎样，这些技术可以弥补我们的不足并且帮我们做很多事情。如果不是这样的话，我们为什么要创造和发展它们呢？

(2010届英语周报第1期A)At eighteen years of age，I flew up to San Francisco to meet a pen pal who I had written to for over a year.The first thing we did when we got home was to bake chocolate chip cookies，and our strong_ties were formed.From laughing at the burnt cookies，to eating the chocolate chips instead of putting them in the dough(生面团)，it was fantastic.We became best friends.Twelve years later，we still reflect on that moment，and laugh with silliness and joy. Fast forward to 2003，I was in my first month of training in radiation oncology(放射肿瘤学)，and scared.I was in a new city，alone，and afraid of having to make a new start.One patient that we were treating used to come into the department with freshly baked goods for everyone once a week with a smile on her face.She was treated with a really tough regimen(疗法)for her cancer，yet she still overcame the pain and exhaustion(精疲力竭)to bake for the department.I once asked her why，and she said it gave her purpose and meaning.

This purpose was far greater for me than a simple cookie.I really didn’t know how to bake，and I told her that.She then invited me to her home for lessons.With her as a guide I learned some of the art of baking.While baking we talked about life，regrets，and dreams.We soon became very close friends. A few weeks later，her husband came to the department and gave me a large box with a handwritten note.I opened the box.Inside was a Kitchen Aid mixer，and the note saying，“Please remember me when you bake，keep at it and you’ll change the world.”He told me that her cancer had spread.She was in her final stages of life.I cried and cried.It was simply the most generous gift that I had ever received. 1．What do the underlined words“strong ties”in Paragraph 1 refer to?

(2009年浙江金丽衢十二校联考)The average American will have three to five careers,10 to 12 jobs，and will hold each one for an average of 3.5 years throughout his or her lifetime，according to the U．S. Department of Labor. Does this sound familiar? Are you still struggling to find the ideal career?

Finding_your_dream_job_may_be_as_simple_as_opening_that_bag_of_potato_chips_in_your_kitchen_cupboard. A study conducted by Alan Hirsch，neurological director of the Smell & Taste Treatment and Research Foundation，Chicago，found that job satisfaction is correlated to your favorite snack. “A person’s job selection reflects his essential essence and his personality，”he maintains. “Food choices — like selections of clothing，movies，and spouses — can provide insight in personality and character structure. Thus，the typical personality traits associated with snack preferences can be used to help predict occupational choices，because a person’s job selection also reflects his essential essence and his personality.”

People who choose potato chips to satisfy their snacking urges have high expectations not only for themselves，but for those around them. Competitive. They usually come out on top in business，sports，and social situations. (Lawyer，tennis player，police officer，CEO) Formal，always proper，conscientious，and principled. People who crave cheese curls have a welldeveloped sense of integrity and maintain the moral high ground with their family，coworkers，and romantic partners. They plan ahead for any possible catastrophe. With bandaids and batteries，the cheese curl lover’ s house is always stocked and ready. ( Real estate agent，psychiatrist(精神病医师)，producer) Selfassured and confident，those who prefer popcorn are best described as takecharge sort of people. They will not hesitate to assume extra work on the job or take on chores at social gatherings. Even though they are self-confident，popcorn lovers are modest and humble，and would never be considered showoffs.Popcorn buffs are hidden successes.(Teacher，artist，truck driver，nurse，judge，neurosurgeon) 5．What does the passage mainly tell us?

A. Snack preference may reflect one’s personality and character structure. B. Snack preference may predict one’s career choice. C. People in different careers may prefer different snacks.

D. Food choices are just like one’s selection of clothing，movies，and spouses. 6．The underlined sentence in the second paragraph implies that________. A. a snack lover is more likely to find his dream job

B. it is becoming much easier to find your dream job than before C. job hunting nowadays is as easy as finding your favorite snack D. we can tell one’s occupational choice by his favorite snack

7．A person who likes cheese curls is most likely to be a________. A. police officer B. judge C. producer D. truck driver 8．The favorite snack of a CEO is probably________. A. potato chips B. popcorn C. cheese curls D. nuts

With the help of science and technology, we human race are now living a much happier life than before. Take the invention of the computer for example, it not only helps us solve difficult mathematical problems to save time, but you can also type any material or information into your computer to communicate with your teammates on your business by the network. Besides, it can take the place of us to deal with many dangerous situations under the control of the programmers. In a way, their advantages are over humans，, and this is why people create some robots with artificial intelligence to help us human beings.

However, some people are worried that dangerous problems will arise from any over-usage of high-tech. Personally speaking, I disagree with it. Anyhow, the technology can make up our shortcomings and help us do lots of things. If not, why create and develop them?
