7."The ancient Hawaiians were astronomers,"wrote Queen Liliuokalani,Hawaii's last ruling monarch(君主),in 1897.Star watchers were among the most esteemed members of Hawaiian society.Sadly,all is not well with astronomy in Hawaii today.Protests have erupted over construction of the Thirty Meter Telescope(TMT),agiant observatory that promises to revolutionize humanity's view of the cosmos(宇宙).
At issue is the TMT's planned location on Mauna Kea,a dormant(休眠的)volcano worshiped by some Hawaiians as the piko,that connects the Hawaiian Islands to the heavens.But Mauna Kea is also home to some of the world's most powerful telescopes.Rested in the Pacific Ocean,Mauna Kea's peak rises above the bulk(巨大的形狀)of our planet's dense atmosphere,where conditions allow telescopes to obtain images of unsurpassed clarity.
Opposition to telescopes on Mauna Kea is nothing new.A small but vocal group of Hawaiians and environments have long viewed their presence as disrespect for sacred(神圣的)land and a painful reminder of the occupaion of what was once a sovereign nation.
Some blame for the current controversy belongs to astronomers.In their eagerness to build bigger telescopes,they forgot that science is the only way of understanding the world.They did not always prioritize the protection of Mauna Kea's fragile ecosystems or its holiness to the island's inhabitants.Hawaiian culture is not a relic of the past; it is a living culture undergoing a renaissance (復(fù)興)today.
Yet science has a cultural history,too,with roots going back to the dawn of civilization.The same curiosity to find what lies beyond the horizon that first brought early Polynesians (波利尼西亞人)to Hawaii's shores inspires astronomers today to explore the heavens.Calls to disassemble all telescopes on Mauna Kea or to ban future development there ignore the reality that astronomy and Hawaiian culture both seek to answer big questions about who we are,where we come from and where we are going.Perhaps that is why we explore the starry skies,as if answering a primal (最初的)calling to know ourselves and our true ancestral homes.
The astronomy community is making compromises (妥協(xié))to change its use of Mauna Kea.The TMT site was chosen to minimize the telescope's visibility around the island and to avoid archaeological and environmental impact.To limit the number of telescopes on Mauna Kea,old ones will be removed at the end of their lifetimes and their sites returned to a natural state.There is no reason why everyone cannot be welcomed on Mauna Kea to embrace their cultural heritage and to study the stars.

64.Mauna Kea is deemed as an ideal astronomical site due to itsD.
A.existing infrastructure (基礎(chǔ)設(shè)施)
B.protective surroundings
C.religious implications
D.geographical features
65.The construction of the TMT is opposed by some locals partly becauseC.
A.it may risk ruining their intellectual life
B.it reminds them of a humiliating history
C.their culture will lose a chance of revival
D.they fear losing control of Mauna Kea
66.It can be inferred from Paragraph 5 that progress in today's astronomyA.
A.is fulfilling the dreams of ancient Hawaiins
B.helps spread Hawaiian culture across the world
C.may uncover the origin of Hawaiian culture
D.will eventually soften Hawaiians'hostility
67.The author's attitude toward choosing Mauna Kea as the TMT site is one ofD.
A.severe criticism
B.passive acceptance
C.slight hesitancy
D.full approval.

6.Edward Wilson is America's,if not the world's,leading naturalist.In The Future of Life,he takes us on a tour of the world's natural resources(資源).How are they used?What has been lost?What remains and is it able to continue with the present speed of use?Wilson also points out the need to understand fully the biodiversity(生物多樣性)of our earth.
Wilson begins with an open letter to the pioneer in environment (環(huán)境) protection,Hnry David Thoreau.He compares today's Walden Pond with that of Thoreau's day.Wilson will use such comparisons for the rest of the book.The problem is clear:man has done great damage to his home over the years.Van the earth,with human help,be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity,Wilson argues,is the key to settling many problems the earth faces today.Even our agricultural crops can gain advantages from it.A mere hundred species(物種) are the basis of our fod supply,of which but twenty carry the load.Wilson suggests changing this situation by looking into ten thousand species that could be made use of,which will be a way to reduce the clearing of the natural hoes of,plants and animals to enlarge farming areas.
At the end of the book,Wilson discusses the importance of human values in considering the environment.If you are to continue to live on the earth,you may well read and act on the ideas in this book.

33.We learn form the text that Wilson cares most aboutB
A.the environment for plants
B.the biodiversity of our earth
C.the wastes of natural resources
D.the importance of human values
34.How many species are most important to our present food supply?A
A.Twenty.B.Eighty.C.One hundred.D.Ten thousand.
35.Wilson suggests that one way to keep biodiversity is toD.
A.learn how to farm scientifically
B.build homes for some dying species
C.make it clear what to eat
D.use more species for food.

5.Last week my youngest son and I visited my father at his new home in Tucson,Arizona.He moved there a few years ago,and I was eager to see his new place and meet his friends.
My earliest memories of my father are of a tall,handsome,successful man devoted to his work and family,but uncomfortable with his children.As a child I loved him,as a school girl and young adult(成人的) I feared him and felt bitter about him..He seemed unhappy with me unless I got straight A's and unhappy with my boyfriends if their fathers were not as"successful"as he was.Whenever I went out with him on weekends,I used to struggle to think up things to say,feeling on guard.
On the first day of my visit,we went out with one of my father's friends for lunch at an outdoor café.We talked along that afternoon,did some shopping,ate on the street table,and laughed over my son's funny facial expressions.Gone was my father's critical (挑剔的) air and strict rules.Who was this person I knew as my father,who seemed so friendly and interesting to be around?What had held him back before?
The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood.Although our times together became easier over the years,I never felt closer to him at that moment.After so many years,I'm at last seeing another side of my father.And in so doing,I'm delighted with my new friend.My dad,in his new home in Arizona,is back to me from where he was.

4.It's 4:50 in the morning when the alarm rings in my ears.I roll out of bed and walk blindly through the dark into the bathroom.I turn on the light and put on my glasses.The house is still as I walk downstairs while my husband and three kids sleep peacefully.Usually I go for a long run,but today I choose my favorite exercise DVD,insanity.Sweat pours down my face and into my eyes.My heart races as I force my body to finish each movement.As I near the end of the exercise,I feel extremely tired,but a smile is on my face.It's not a smile because the DVD is over,but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping,smoking,food,work,or even chocolate.But I need exercise to get through each day.Some shake heads when they see me run through the town.Others get hurt when I refuse to try just one bite of their grandmother's chocolate cake.They raise their eyebrows,surprised by my"no thank you,"or by my choice to have a salad.Over the years,I have learned it's okay to just say"no".I shouldn't feel sorry for refusing food that I don't want to eat.
So what drives me to roll out of bed at 4:50a.m.?What gives me the reason to just say no to ice cream?Commitment.A commitment to change my life with a way that reduces daily anxiety,increases self-confidence and energy,extends life and above all improves my body shape.This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right.It's through commitment and sweat that I can make a difference within myself inside and out.

25.Why is there a smile on the author's face in the morning?D
A.Because she sees her family sleeping peacefully.
B.Because she finishes her favorite exercise.
C.Because she enjoys the interesting DVD.
D.Because she feels a sense of achievement.
26.Which of the following is true according to Paragraph 2?C
A.She doesn't treat others politely.B.She likes to make others surprised
C.Others don't understand what she does.D.Others try to help her by offering her food.
27.What does the underlined word"Commitment"in the last paragraph mean?B
A.Good health.B.Firm belief.C.A strong power.D.A regular habit.
28.What can we learn about the author from the text?C
A.She acts in a strange way.
B.She wants to look different from others.
C.She aims to develop a good body shape.
