A. survive the emergencies B. avoid a bear attack C. deal with a choke D. find our way DI have a friend who lives by a threeword philosophy: Seize the moment. Just possibly, she may be the wisest woman on this planet. Too many people put off something that brings them joy just because they haven’t thought about it, don’t have it on their schedule, don’t know it is ing or are too strict to depart from their routine.I can’t count the times I called my sister and said, “How about going to lunch in half an hour?” She would gasp and stammer (結(jié)結(jié)巴巴地說), “I can’t. I have clothes on the line. My hair is dirty. I wish I had known it yesterday, I had a late breakfast, and it looks like rain.” And my personal favorite response: “It’s just Monday.” She died a few years ago. We never did have lunch together. From then on, I’ve tried to be a little more flexible.Life has a way of going faster as we get older. The days get shorter, and the list of promises made to ourselves gets longer. One morning, we awaken, and all have to show for our lives is repetition of “I’m going to” , “I plan on” and “Someday, when things are settled down a bit.”When anyone calls my “seize the moment” friend, she is open to adventure and available for trips. She keeps an open mind on new ideas. Her enthusiasm for life is contagious. You talk with her for five minutes, and you’re ready to trade your bad feet for a pair of Rollerblades and skip an elevator for a bungee cord.My lips have not touched ice cream in 10 years . I love ice cream. The other day, I stopped the car and bought a tripledecker. If my car had hit an iceberg on the way home, I would have died happily.Now ... go on and have a nice day. Do something you WANT to … not something on your SHOULD DO list.67．The example of the writer’s sister serves as ________.A. an argument B. an introductionC. a support D. a conclusion68．The writer thinks that the excuse “It’s just Monday.” is acceptable, because ________.A. it is still likely that they can have lunch together some time laterB. it sounds most reasonable of all the excusesC. it shows respect for the writer’s suggestionD. it indicates the time when they can have lunch together69．The underlined word “contagious” in the fourth paragraph means “________” .A. accurate B. influential C. practical D. flexible70．What is the purpose of the writer by writing this passage?A.

The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters’ PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already bee slightly more acidic over the last century.These researchers have tried to predict what will happen in the future by bining what we know about the history of the oceans with puter models of climate change. “This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira. “And we predict the amount of future acidity will exceed(超過) anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.However, it is not absolutely clear what that means for ocean life. Most organisms live near the surface, where the greatest pH change would be expected to occur, but deepocean life forms may be more sensitive to pH changes. Coral reefs(珊瑚礁) and other organisms whose shells contain calcium carbonate(碳酸鈣) may be particularly affected if the water’s acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming. But Dr Caldeira said that such a strategy should now
