You know it’s truly amazing how the Jewish people survived after thousands of years of being slaves, persecuted(追捕), and even attempted genocide (種族滅絕)when Hitler’s Nazi murdered 6 million Jews! That’s why in 1934, Germany was the    36    place to be a Jew. When Hitler’s teenage gangs    37    his village, the little    38    boy, Heinz, was just 11 years old.

    Every day Heinz’s parents taught their    39    how important it was to learn    40   . When the Nazi gangs terrorized their village on the streets daily, Heinz’s parents knew that just one moment of losing control of their    41    against their rulers could    42    the death of the family. So Heinz learned to stay out of their    43   , sometimes crossing the street or taking a    44    road home.

     But one day, young Heinz was finally    45    by one of Hitler’s bullies(暴徒). For the first time, Heinz was    46    to talk to a Nazi youth. But by staying calm and    47    choosing his words, Heinz surprised himself when he    48    his way out of trouble and    49    this bully not to hurt him    50    to let him go. That day, Heinz discovered his survival skill of talking and    51    with others. It was a major    52    point that changed his life---and later changed the world.

      After a few years, Heinz’s family escaped from Germany and moved to America. But Heinz never forgot how to talk with people and help bring    53    between enemies. You see, that 11-year-old boy who had    54    his first peace settlement with a Nazi bully, later became one of the greatest ambassadors of peace in the world. You’ve probably heard of him- not as Heinz- but by his American name: Henry Kissinger, the    55    US Secretary of State.

When I moved into an empty dormitory for the first time two years ago, I was certain of a few things. Firstly, I realized that I didn’t 31 anybody at the school. Secondly, I knew that I wanted to work hard at my lessons and 32 something useful. And thirdly, I wanted to have a good time with new classmates, without my parents around.

The first 33 frightened me in the beginning. But that 34 quickly disappeared. It was the other two goals 35 ended up being my difficulties. I knew that it was 36 to devote enough time to class and to social efforts. But I wanted to 37 in both. I knew this would be a 38 , but I didn’t realize how much until classes began.

I got on well with the other girls who lived in my dorm. 39 , instead of finishing my homework 40 it was due, I went upstairs and had ice cream with my neighbor. I always finished it the next day between classes. I knew 41 wasn’t very good and the grade I 42 showed my lack of effort.

I was 43 that I needed to find some sort of balance.

So I created a schedule that would 44 my time up between going to class, doing homework, and relaxing. It seemed like a good idea, 45 I was only able to 46 it for a few days. A schedule like that was too much pressure.

So I tried another 47. Each week I made a list of everything I had to get done during that week.

Then, under the list of things I had to get done, I 48 a list of things I could do if I had time.

This is the method I have used since then. I’m glad that I’ve learned to 49 things and it has 50 prepare me for what is to come after graduation.

Chinese people think a lot about food．In fact，I think that they are sometimes obsessed(癡迷) with it．My first experience of this   16   of Chinese culture came at a banquet during a trip to Beijing in 1998．I had eaten Chinese food often，but I could not have  17  how fabulous(豐盛的)a real Chinese banquet could be．The first six or seven dishes seemed to  18  the table, with plates dangerously   19  one on top of another．I thought this vast    20  of food was the total number of dishes to be served，and I started eating    21  ．Everyone else just   22  a bit of each dish and then put their chopsticks down，continuing to chat．“They can't have very big appetites,” I thought．

To my surprise，more dishes   23  ，plus soups，side dishes，and desserts．There was enough to feed a whole army．No   24  my fellow guests had had only a few  25  of each dish；they knew what was still to come．But I was already so   26  that I could only    27  as the banquet continued．

Another aspect of“food culture”is that the Chinese seem to eat almost every part of every animal——much to the    28   of many westerners．Stomach，ears，tongue，tail，hoof and lungs are all likely to   29   on the dinner table in front of you．The first time I saw a three-year-old kid  30   chewing a chicken's head I had bad dreams for weeks．

These days I enjoy that sort of food myself． 31  ，there are other kinds of foods that have taken longer for me to  32  ．The infamous(臭名昭著的) choudoufu is a(n)   33  ．(The name says it all：“stinky tofu”．) Just when I got used to it,  I found another  34  on a trip to Hunan：deep-fried choudoufu，a horrible black substance that looked and    35  about as appetizing as a burnt tennis shoe．Maybe I'll get used to that, too—some day．

What causes your computer a slow one? The problem lies with changes that occur to the PC's software. The 2 most   51   causes of slowdown (along with easy solutions) are:

Registry errors  -  the most common problem

  Every    52    you load a program, game or file, your PC's software registry is updated with new instructions needed to operate that item.   53   , when the item is removed, these instructions usually remain on your PC.  Every time you run your computer it   54   to carry out these instructions but, because the related program can't be found, it causes a registry error.  Your PC is doing a lot   55   work than it should be and the result is a significantly   56   computer.

  One of the best ways to manage this is with a    57    little tool. This program scans, identifies and    58  registry errors - resulting in a computer that's a lot more like it was when you   59  bought it. 

Spyware and viruses

  Spyware and viruses are software programs that are loaded on your computer   60   your knowledge or permission.  They have various purposes,   61   :

  Changing the default search engine in your browser

  Tracking your web surfing    62 

  Stealing your personal    63  

  Most spyware and viruses get onto our computers through files that we   64   from the internet or as attachments to emails. They tend to   65   up a lot of computing power and as a   66   will significantly slow down the computer.

  The simple rule of thumb to follow is to never download any   67   software programs from companies you do not know and trust, especially screensavers, emoticons and the   68   . In addition, make sure you have a good anti-virus / spyware removal software running at   69   times.
