Mexico City is truly one of the most amazing cities in the world with a mixture of both the old and new world. From the moment your plane starts to land in this vast city, you know that your trip will be quite an adventure.

Once in your taxi and the moment you leave the airport, you are amazed at the large amount of slow traffic. The volume of the traffic can be stressful to some.

The "Paseo de la Reforma (改革大道)", running southwest across the city, is one of the major tourist and business areas in Mexico City with many high quality hotels only walking distance from great restaurants and other tourist attractions. The only problem you will have is trying to see all of these sites during your vacation time.

One of the most popular attractions in this area is the National Museum of Anthropology along the northwest part of the street. There are thousands of artifacts on display showing the history of the area and numerous items found from the many Aztec sites in the area. Walking southwest from the museum, you will soon reach the Mexico City Zoo, which is a great place to spend an afternoon.

Across the street from the museum is the Chapultepec Castle, once an important site in the Mexican-American war. It's also a good idea to take the train up the hill to where the castle is located as the hill is steep (陡峭的). It's important to keep in mind that Mexico City is over 7,000 feet above sea level and some feel it difficult to breathe when walking.

You can take a taxi to the Coyoacan market during the evening on a weekend. It's a great place to get some cheap souvenirs to bring back home and to enjoy some traditional Mexican cuisine. However, you must be careful where you eat and that the meat is well cooked.

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 a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved 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 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 doing so, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

A. nervous                        B. sorry              C. tired               D. safe

3.What does the author think of her father after her visit to Tucson?

A. More critical.                                B. More talkative

C. Gentle and friendly.                           D. Strict and hard-working.

4.The underlined words “my new friend” in the last paragraph refer to_____ .

A. the author’s son                           B. the author’s father

C. the friend of the author’s father              D. the café owner

As demand for power and fuel grows steadily in the coming decades, we must consider every possible energy source（来源）on hand if we're to meet the world's needs. And because clean natural gas is found in great plenty, there is little doubt that it will play a major role on the world energy stage in this century, much like oil did in the last. But, like oil, gas reserves are concentrated in just a few places in the world, usually far from where they're needed most. And that's only part of the challenge. The world has had well over 100 years to search for oil and to build the necessary facilities（设施）to bring it to market; the natural gas facilities, particularly when it comes to liquefied（液化）natural gas（LNG）, are not nearly as developed.

    So what needs to be done? On the supply side, producing nations need policies that allow for better development of their natural gas in an open, stable business environment, not one in which the rules of the game change without warning. The governments of consuming nations, on the other hand, must make policies for sustainable（可持续的）development to ensure they'll have enough supplies in the future. That means building the related facilities, including LNG stations. This, in turn, will require coastal areas to allow these necessary, but not necessarily pretty, facilities to be built in their backyards. And energy companies have a responsibility to be good neighbors in those areas by operating these facilities responsibly and safely. They must also continue to put in the billions of dollars needed to build the complex transport and storage facilities required to bring more gas to market.

    Expanding and diversifying（使多样化）energy sources by using more natural gas could lead to lower fuel prices and to greater energy security. We've taken some of the steps to get started, but we need your help to get the rest of the way.
