A

It’s hard to talk to dad sometimes.His silence about his feelings and thoughts made him mysterious and hard to see through.You could never break his hard shell and get to know him.And he seemed to want to stay that way too.

But a year ago when my relationship with my wife and career took a hit.I needed my dad to pull back the curtain so I could see him as real and accessible.I was facing serious problems and I wanted to know whether he had faced them before and how he had found his way,because I felt like I had lost mine.In desperation,it occurred to me that sending an email might be the key,so I wrote him one,telling him about my regrets and fears,and I asked him to answer,if he felt like it.

Two weeks later,it showed up in my inbox:a much-thought,three-page letter.Dad,a

68-year-old retired technologist and grandfather of four,had carefully considered my message,and crafted a response.He mentioned his lost love,the foolish mistake he made in career and the stupid pride he had between him and his parents.He comforted me that “life will still find its right track despite many of its twists and turns.”

I closed the email and started to cry,because I wished I had opened up earlier but was grateful it wasn’t too late.I cried because at 33,in the midst of my own struggles,his letter instantly put me at ease.And I cried because in the end,it was so simple:I just had to hit “Send.”

We’ve since had many email exchanges.This increasing communication opened a door into

his world.My problems haven’t been magically solved,but getting to know my dad better has made the tough stuff more manageable and life sweeter.It’s hard to talk to dad sometimes,but I’m glad I found a way to talk to mine.

21. The author’s dad can be best described as ______.

A. quiet and caring

B. optimistic and careless

D.My Mysterious Dad

23. The underlined part in Paragraph 2 can be best replaced by”______”.

A.draw the curtain

B. become more optimistic

C. show his true self

D.clear the misunderstanding

24. Which of the following is NOT true?

The Coral Sea is home to an amazing variety of turtles,sharks,whales,dolphins,large

fish,birds,corals,plants,and many other species.Many of these species are endangered elsewhere in the world,but still survive in the healthy environment of the Coral Sea.

The Coral Sea is a large series of coral reefs located off the northeast coast of Australia.This area is three times larger than Australia’s famous Great Barrier Reef,which the Coral Sea borders.

The Coral Sea is one of the few coral reef environments that have remained largely undamaged by over-fishing,oil and gas exploration and pollution.However,statistics show that coral reefs around the world are disappearing five times faster than rainforests.It is very likely that in the near future the Coral Sea will face the same threats to its existence.

The Australian government is currently looking at options for protecting the Coral Sea but has made no decisions.Environmentalists are pushing for laws to declare the Coral Sea area a marine protected area.This world mean a large “no-take zone” for fishermen,a no-exploration zone for gas and oil companies and a no-dump zone for pollution.This world make the Coral Sea a marine park larger than any in the world.

We can write letters to Australian leaders,Australian environmental protection agencies,and Australian friends,to let them know that people worldwide support this protection of the Coral Sea.To lose this last great marine wildness world would be a loss for the whole world.

One of the biggest social issues in Japan is the increasingly low marriage rate among young people and the small birth rate,which led to an aging and eventually shrinking(萎缩) population.Most young Japanese women simply don’t seem interested in having many children.

Now what began in Japan is happening globally.As David Brooks wrote,birth rate is becoming smaller in much of the world,from Iran-1.7 births rate per woman-to Russian,where low birth rates connected with high death rates mean the population is already shrinking.And this includes US,which has long had higher birth rates than most developed nations.Aging countries will face the burden of caring for large elderly populations without a larger source of young workers.

It’s true that global aging is going to present some major challenges.Who will take care of the elderly?Will an older world be less active and slower to change and adapt?It’s all

true.Sometimes I worry about a coming generational war over resources,just as I worry about how I will take care of my own parents in their old age,just as I worry about who might take care of me.

But here’s the thing:an older world may have less pressure on the environment.As we all know,the environment is the real victim of overpopulation.

So maybe a world that grows slower and grows older will put less pressure on the environment,and buy us a few more years to ensure our energy use,along with our birthrates,reaches a sustainable(可持续的) level.After all,we’re supposed to get smarter as we got older.Hopefully that holds true for the planet as well.

29. The population issue in Japan was mentioned to ______.

A. show young people’s preference to marriage

B. introduce the topic of global birth rate becoming smaller

C. indicate the deeper cause of Japan’s depression

D.emphasize the revolution of Japanese women

30. What’s the author’s attitude to the worldwide birth rates becoming smaller?

A. Anxious.

B. Disappointed

C.Hopeful.

D. Doubted

31. Which of the following statements is TRUE according to David Brooks?

A.The birth rates all over the world are becoming smaller.

B. The most developed countries have higher death rates.

C. America is the only developed country with higher birth rate.

D. Birth rate’s becoming smaller means a great risk to aging countries.

32. Which will be caused by low birth rates according to the passage?

A. Aging society.

B. Environmental problems.

C. High death rates.

D. Low employment rates.
