Over the last six years I have learned what patience is. Growing up I did not have this virtue(优点) and it is a very important virtue to have. Now I can see that if you are patient you will almost always get what you want if you are supposed to have it. I gained patience when I lost my freedom. I knew that I would eventually get it back in time.
I was locked up in prison for a period of six years because at 19 years old I was playing with a handgun and I accidentally shot and killed my friend. The first couple of years was the hardest. I was always stressed out about everything. Time was dragging by because I was always paying attention to it. While I was locked up，Tom who I talked to helped put this virtue in me. He told me that it was possible that he would never make it home but that being patient and believing that one day he would was what had made him feel better. After a while I realized why he said a lot of things to me. Once I stopped paying attention to the days and just kept in mind that I would get freedom, it seemed that my time passed quickly.
Now I am home and can see that patience paid off for me. I now use this virtue in my daily activities. I know that sometimes life gets hard and that it will pay in the end to stay patient and not to get discouraged. So if you are having a hard time in life, be patient and it will eventually
work out one way or another.

I think people everywhere dream about having lots of money. I know I do. I would like to earn large amounts of money. You can win a large amount of money in the United States through
lotteries. People pay money for tickets with numbers. If your combination of numbers is chosen, you will win a huge amount of money—often in the millions.
A few years ago, my friend Al won the lottery. It changed his life. He was not “born with a silver spoon in his mouth”. Instead, my friend was always short of money. And the money he did earn was chicken feed.
Sometimes Al even had to accept handouts(施舍物) from his friends. But do not get me wrong. My friend was always very careful with the money he spent. In fact, he was often a cheapskate. He did not like to spend money. The worst times were when he had no single penny left.
One day, Al scraped together a few dollars for a lottery ticket. He thought he would never gain lots of money unexpectedly. But his combination of numbers was chosen and he won the lottery. Al was so excited. The first thing he did was buy a costly new car—one thing that he normally would not buy. Then he started spending money on unnecessary things. It was like he had “money to burn”．
When we got together for a meal at a restaurant, Al paid every time. He would always tell me the money made him feel like a millionaire. But, Al spent too much money. Soon he was “down and out” again. He had spent his “bottom dollar”—his very last amount. He did not even save any of the money.
I admit I do feel sorry for my friend. He had enough money to “live like a king”. Instead, he was back to “living on a shoestring”— a very low budget. Some might say he was wise about small things, but not about important things.
68．What does the author desire to do like others? A．To combine the numbers perfectly. B．To make a huge fortune. C．To be chosen for selling lotteries. D．To get in touch with millionaires.
答案：B 细节理解题。根据文章第一段中的“I know I do. I would like to earn large amounts of money.”可知，作者也像其他人一样，想挣一大笔钱。故选B。

答案：C 细节理解题。根据文章第二段可知，Al总是缺钱，他赚的钱少得可怜。第三段又表明朋友经常帮助他。故选C。
70．What does the fourth paragraph imply?
A．Al always had good luck in life. B．Al valued his money above his life. C．Al had loved the expensive car probably. D．Al pretended to have more money.
答案：C 推理判断题。第四段第五句中的“The first thing he did was buy a costly new car”表明，Al有钱后的第一件事就是买了一辆豪车，这辆车可能是他以前喜欢但买不起的东西。故选C。
71．When a person is “down and out”， ________. A．he is as poor as a church mouse B．he lives a life like other people C．he has set aside all his money D．he is looking forward to big success
答案：A 细节理解题。根据文章倒数第二段的“He had spent his ‘bottom dollar’—his very last amount.”可知，他把最后一笔钱也花掉了，他又过起了穷困潦倒的生活。故选A。

Apart from five carp (锂鱼) that got into Lake Erie in 2004, no Asian carp have been found in the Great Lakes—just traces of their genes, known as “environmental DNA”， or eDNA. Those genes could have come from feces or scales (粪便或鳞片) in the water, but U．S. Geological Survey fish biologist Duane Chapman says the pattern of where they were found suggests more than that.
“By far the most likely explanation of those samples is there are one or more live fish of each species (bighead and silver carp) in the Great Lakes，” he says. “I find it hard to believe that the pattern of samples they've found could come from any other source.”
The U．S. Army Corps of Engineers began building a series of electric barriers along the Chicago Ship and Sanitary Canal in 2002, aimed at keeping Asian carp and other invasive species out of the Great Lakes. But if there really are Asian carp on the lake side of the electric Barriers, how could they have gotten there?
“The simple answer is we don't know，” says U. S. Fish and Wildlife spokeswoman Ashley Spratt. “They were specifically designed to keep them from getting into the lake, and they have been very effective. Now the Army Corps is working to speed up construction of a new electronic barrier to strengthen the existing barriers.”
The eDNA has renewed calls to shut down the shipping locks (水闸) altogether, which leaders in Chicago and Illinois oppose. They've drawn support from the Ohama administration, but the anger of other Great Lakes states—Michigan sued(提出诉讼) to close the locks last year, and although the U. S. Supreme Court declined to hear the case, Michigan, Minnesota, Wisconsin,
