I ran into a stranger as he passed by. “I'm so sorry!” was my reply. Then he said, “Excuse me too. I wasn't 36
watching for you.” We were very polite. Then we went on our way after saying 37.
But at 38 , a different story is told. How we treat our loved ones, young and old. Later in the kitchen, as I 39 our meal, my daughter walked up to me, very still. When I turned, I 40 knocked her down. “Get out of the way!” I shouted. She stepped away silently, with her little heart 41 .
That night, when I lay
By this time, I felt sad and small and now my own tears had begun to fall. I quietly went and knelt by her 47 : “Wake up, my dear,” I said, “Are these the flowers you picked up for me?” She smiled, “I found them out by the tree. I 48 them in a napkin, just for you. I knew you'd like them, especially the 49 .” I said, “I am so sorry that I missed them today... And I 50 have shouted at you that way.”
And she whispered, “Mommy, that's okay.. I still love you 51 .” I hugged her and said, “I love you, too and I LOVE the flowers.”
Do you know that: if you die tomorrow, the 52 you are working for could easily replace you in a matter of days. But the family you leave _53 will feel the loss for the rest of their lives. And come to think of it, we pour ourselves more into our 54 than into our families--an unwise investment indeed.

If you think a Web site designed especially for complaining sounds unique, then think again. If you have a complaint, there are hundreds of sites that allow you to get it off your chest. Sites exist for complaining about such things as defective products, government inefficiency, and offensive advertising. There are even sites where you can complain about anything that bugs you, including love, family, or just the weather. These Web sites won’t actually do anything about your problem; they just let you blow off steam. Here’s a sampling of complaints people have written:
1. Something I can’t stand is pencils! They need to be sharpened after every page you write. And then don’t you hate it when they start to make a scratching noise?
2. Have you ever noticed that in most schools you have chairs with armrests to write on attached to the right-hand side of the chair only? Where are the desks for left-handed people? It’s very uncomfortable for us “lefties” to use these desks made for right-handed people!
3. I see red every time I get my credit card bill from the bank. There’s always a check for a large amount attached with an invitation to sign it and spend it on “anything I want.” I have enough sense to rip it up and throw it away, but I bet a lot of people don’t. They don’t realize that when they use the “free check”, the expense gets put on their credit card bill. Boy, they must be surprised when they get that bill! I think that banks shouldn’t be tempting people with those checks.
4. It isn’t fair that only the
60. If you have a complaint and go to some Web sites, ___________.

can’t get a free offer in the
C. People can’t get a free offer outside the
63. What could be the best title for the passage?
A. Excellent Web Sites. B. Complaining Online.
C. Sampling of Complaints. D. Writing out Your Complaints.
C
To be “historically minded” is to see things in relation and in perspective, and to judge tolerantly. We must remember how differently men have thought and acted in different times. We must always keep an open mind, ready to receive and weigh new evidence. If we grasp this idea, we will never think that a historian is someone who can remember dates. That childish idea is like calling a man a statesman because he can remember the names of voters in his district. A waiter could remember more names and a telephone operator more numbers than the greatest historian.?
The true historian is not content to take all his facts from other historians. Today he makes sure that his statements are based on sound “documents” or “sources” which go back to the time of the facts themselves. But the historian needs always to be in his guard not to be misled by his sources. A document may not be a real one. Its author may be lying on purpose for some reasons. He may be so greatly influenced by national, religious, party or personal backgrounds as to be totally unfair to the other side. If honest, he may be misinformed as to the facts and mistaken in his inferences.?
Anyone who reads the accounts published in the different countries concerning the causes and results of wars will realize that the historian needs caution and training in handling these sources. The trained historian asks first: “Did this writer mean to tell the truth?” and second; “Was he in a position or frame of mind to tell the truth even if he wants to?” Every statement must be patiently weighed and tested and combined with all other available information in order to get at the truth.?
A. always keeps an open mind to history? B. looks at one historical event without relating it to another
C. sees things from a single point of view? D. refuses to accept new evidence?
65. In Paragraph l the author means to illustrate that ____.?
A. different men think and act differently?
B. the study of history is not merely a matter of remembering dates?
C. a statesman can remember the names of voters in his district?
D. a waiter can remember more names than the great historians?
66. The true historian should base his statements on ____.?
A. findings of other historians? B. documents created at the present time?
C. his own inferences? D. sound historical materials?
67. Which of the following is the topic of Paragraph 3? ?
A. Some historical documents may not be real.? B. Historians should be careful about their sources.
C. Some authors may not be honest.?? D. Historians may be influenced by their own backgrounds.?
D

Effective environmental
protection laws and other measures have led to the improvement of water quality
in Tai Hu lake in
The news was announced by officials from the provincial environmental protection bureau, which has just conducted an inspection of the lake area.
By the end of September, about 80 per cent of industrial pollutants met required standards and the lake is expected to be cleaner by the end of the year, officials said.
According to targets set by the State Environmental Protection Administration, all polluting enterprises must meet set standards by the end of this year or they will be shut down.
The
However, the quality of water in the lake has been deteriorating(恶化)at an alarmingly rate in recent years, which has caused concern from the government and local people.
Pollution is so high mainly because people do not have enough environmental awareness and have put economic benefits ahead of their surroundings.
Economic development in the area has been rapid with hundreds of factories being built. But officials say most of these do not have the anti-pollution equipment or measures they should have.
Because of the lack of
waste treatment facilities, wasted water and other rubbish from residential
areas in nearby towns and villages flow into rivers which are connected to
Realizing the seriousness of the situation, the provincial and local governments began to tackle the problem.
Experts were invited to offer suggestions and laws and regulations were issued. All newly built factories and enterprises in the lake area were required to install necessary anti-pollution facilities before they can go into operation.
Also, some wasted water treatment works will be built in the three cities.
72. We can know from the text that the Taihu lake area is a place where_____.
A. the water in the lake was very clear B. the factories are trying their best to protect the water

D. the people and the government are paying more attention to the pollution.
73. Most of the factories now _____
A. are sending the quite a little pollutant to the lake B. can satisfy the required standards
C. have to stop their production D. have to think of other ways to survive.
74. The reason why the pollution became so serious here is that ___
A. the people here didn’t know how to deal with the pollution
B. the factories thought the economy was the first
C. the local governments didn’t know the situation at all
D. the factories had no the technology to control the pollution.
75. After reading the text, we can learn that_____.
A. the economy development will do harm for the environment
