Monarch butterflies(黑脉金斑蝶)are a common summer sight in the northern United States and Canada. These large orange and black insects brighten parks and gardens as they fly lightly among the flowers. What makes monarchs particularly interesting is that they migrate(迁飞)— all the way to California or Mexico and back. They are thought to be the only insect that does this.
Every year in the late summer monarchs begin their journey to the south. Those heading for Mexico go first for the Louisiana-Mississippi area, and then fly across the Gulf of Mexico into Texas. Once in Mexico, they settle themselves in one of about fifteen places in a mountain forest filled with fir trees. Each place provides a winter home for millions of monarchs. There are so many butterflies that they often cover entire trees. When spring comes, they begin their long journey north. 
The question is often asked whether every butterfly makes the round-trip journey every year. And the answer is no. The average monarch lives about nine months. So one flying north might lay eggs in Louisiana and then die. The eggs of that generation may be found in Kentucky; the eggs of the next generation may end up in Wisconsin or Michigan. The last generation of the season, about the fourth, will make their way back to Mexico and restart the journey.
Scientists learn about monarchs’ migration by catching and making marks on the insects. By recatching a monarch with such a mark and noticing where it came from, the next scientist can get to know things like the butterfly's age and its routing(路线).
68. One of the places where monarchs spend the winter is _____.
A. the Gulf of Mexico                                    B. an area in Mississippi 
C. a forest in Mexico                               D. a plain in Texas
69. The routing of monarchs’ migration can be learned _____.
A. by examining the marks made on them    B. by collecting their eggs in the mountains
C. by comparing their different ages            D. by counting the dead ones in the forests
70. Which is the best title for this passage?
A. Migration of monarchs.                         B. Scientists’ interest in monarchs.     
C. Winter home of monarchs.                            D. Life and death of monarchs.

Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.
Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.
Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (灾难性的) levels unless we develop power sources that are both cheaper and cleaner.
It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.
According to the passage, the science of the future is likely to be ________.

A.electronics B.biotechnology
C.genetic engineering D.nuclear technology

The materials produced with organic chemistry are ________.at present.

A.as good as wool
B.as good as an insect's body
C.better than natural materials
D.not as good as natural materials

According to the passage, it may soon be possible ________.

A.to transplant human organs
B.to make artificial hearts and eyes
C.to produce drugs without side effects
D.to make something as good as human skin

In 1996, Arthur C. Clarke predicted that_______.
A. the Chernobyl disaster would happen in two years
B. we will never stop using non-renewable power sources biological
C. oil, gas and coal could be repeatedly used in the future
D. power sources would be put into use soon
What do we learn from the last paragraph?

A.Biological power will keep all its promises.
B.Biological power is cheaper than nuclear power.
C.Biotechnology can solve all our future energy problems
D.Biological power may not be as dangerous as nuclear power

A huge shire horse in Australia has been declared the biggest horse in the world by its owner , beating the current Guinness World Record(吉尼斯记录) by several inches .
The huge five-year-old , from Pakenham , S. E Australia , measures an amazing 20.1 hands , or 2.057m tall . He weighs over 1.3 tons ( 1,300kg) — about the same as a small car — and is still growing .

Although she says that she is not interested in the Guiness Book of World Records , nevertheless Jane has carried out her own research and is sure that Noddy comes top . “ The nearest is a horse in Texas , at 20 hands ,” says Jane . “ Noddy is already an inch taller than that . The frightening thing is he still hasn’t finished—shire horses aren’t fully grown until they’re about six or seven .”
Jane has said that Noddy could be sold overseas , possibly even fetching a record price to match his height . She is unwilling to sell , but to fund the high cost of keeping him she needs to put him to work . “ He needs a job . It’s very hard to find jobs for such a big horse in Australia . I wish he could stay here but I’ve tried everywhere , ” she says regretfully . “ I just want people to enjoy this beautiful animal as much as I do .”

People in cities all over the world shop in supermarkets. Who decides what you buy in the supermarket? Do you decide? Does the supermarket decide?
When you enter the supermarket, you see shelves full of food. You walk in the aisles (走道) between the shelves. You push a shopping cart and put your food in it.
You probably hear soft, slow music as you walk along the aisles. This may be an attempt to please you, so you will enjoy shopping. Some supermarkets want to increase their profits by playing soft and slow music, because the slow music makes you walk slowly and you have more time to buy things.
Fresh fruit and vegetables are usually put near the entrance. When you arrive at the supermarket, you think about the kinds of fruit and vegetables you need first. Once you’ve got that out of the way, you can relax and do the rest of the shopping without any hurry. Besides, if you see fresh goods first, it gives you a “feel good” impression of freshness, so you can not help spending your money.
Maybe you go to the meat department then. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk past all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.
Most of the food in supermarkets is very attractive. It all says “Buy me quickly!” to the customers. The fresh fruit and vegetables say “Buy me quickly!” as you walk by. The expensive meat says “Buy me quickly!” The supermarket tells you what to buy.

Finally, I got a part – time job working at the local coffee shop. I had figured that the job would be easy. However, the actual situation was not what I had expected. The customers were hard to please. There was always too much sugar, too little ice, or not enough skimmed milk. However, I kept at it.
One rainy day, Hank, one of my regular customers, came in looking sad and defeated. I asked what the problem was and if we could help, but Hank wouldn’t tell me any details. He just said he felt like going to bed, pulling the sheets up over his head, and staying there for a few days. I knew exactly how he felt.
Before he left, I handed him a bag of his favorite type of doughnuts along with his iced coffee. He looked at me skeptically because he hadn’t ordered anything else except iced coffee.
“It’s on me,” I told him. “Have a nice day.”
He smiled and thanked me before turning around and heading back out into the rain.
The next day was a horrible one. The rain kept pouring down and I spent my afternoon hanging out the window, handing people their orders. What’s worse, no one felt like tipping that day.
However, around 7:00 pm, Hank drove up to the window. Instead of ordering anything, he handed me a single pink rose and a little note. He said that few people take the time to care about others nowadays and he was glad there were still people like me in the world. I was speechless and very touched; I hadn’t thought that I had done anything incredible.
The note read:
Christine,
Thanks for being so sweet, kind and thoughtful yesterday. I was sincerely touched by you. It is so nice to meet someone that’s nice, warm, sensitive and unselfish. Please don’t change your ways because I truly believe that you will excel. Have a great day!
Hank
Later, I did come across more complaining customers. But anytime I felt sad or just sick of coffee, I thought of Hank and his kindness. Then I would smile, hold my head up high, clear my throat and ask politely, “How can I help you?”

Have you ever noticed that the more you have the more you want? Let’s face it. Thinking our life is good enough doesn’t come naturally to many people. When we have high expectations of everything in life we will run into disappointment. Only when we are aware that needs are different from desires can we live with satisfaction. Here are a few ideas to help you be happier with what you have and who you are.
Focus on what you are thankful for. Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have. Learn to reflect on how much better things are than they could be. Focus on what you are thankful for. Write down 5 things you are grateful for right now.
When we hold onto regrets from decisions we have made, it can really poison our well-being. Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner. What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment.
When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied. Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position. Compare yourself less with others so you can be satisfied more.
When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you. Learn to slow down and absorb the wonder and beauty around you. Stay present and focus on the task you’re undertaking at the moment. Don’t let the life pass you by because you’re always on the go and distracted by ambition.
Practice looking at life through the lens of contentment and it will become more natural.
How can we live with contentment?

B.Learn from successful people.
C.Focus on your future goals.
D.Create chance to learn more.
