【題目】NASA-s New Horizons probe（宇宙探測器）flew by Pluto（冥王星）this morning, sending back history's first up-close looks at the vast freezing-cold world. Closest approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface.

After today's close encounter, all the nine solar system's traditionally recognized planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's Mariner 2 probe flew past Venus, a planet in the solar system. More than l,200 scientists, NASA guests and important persons, including 200 reporters, watched the flyby live at New Horizons' mission control center.

That close encounter has been a long time coming. The$723 million New Horizons mission launched in January 2006 but began taking shape in 1989. "New Horizons is'a capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the first completion of the observations of our solar system. It-s giving us a new idea about how we human beings fit into the universe."

New Horizons "faced a crazy number of challenges," Stern, a driving force behind New Horizons said, "So many people stuck with this for so long. They got knocked down; they stood up. They got knocked down again; they stood up again.”

In a coincidence, today's close approach falls on the 50th anniversary of the first flyby of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship.

There are no longer nine officially recognized planets, of course. The International Astronomical Union regarded Pluto as “a dwarf planet" in 2006 in a decision that remains controversial（有爭議的）today.

A. Ideas still vary in the identity of Pluto.

B. Only scientists could watch the flyby live.

C. Mars is the first planet visited by a spaceship.

D. New Horizons mission aimed to observe the solar system.

D. people are likely to find new ways to fit into space

【3】Which is the best title for the passage?

【答案】

【2】D

【3】D

【2】D 深層推斷題。從第三段It-s giving us a new idea about how we human beings fit into the universe."結(jié)合本段內(nèi)容可知D為正確選項。

【3】D標(biāo)題選擇題。從第一段Closest approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of Pluto.知D 正確。

【題目】My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents’ situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on.

I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, “Great opportunity.”

“What is it?” I asked.

“To talk, you and I” he said. “To hold a private little meeting about what we’re going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in.”

“But we can't do anything about it. Grandpa,” I said, surprised that here was someone with whom I could share my feelings and someone who was in the same “boat” as I was.

And that's how the most unbelievable friendship between my grandfather and me started. Sitting in the dark, we talked about our feelings and fears of life — from how fast things change to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. “Well,” he said, “I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!”

【1】I wished to get out of the house because __________.

A. I was eager to have fun with my best friend

B. I found nobody to share my feelings with

C. I wanted to escape from the dark house

D. I planned to tell my friend about my trouble

【2】 Grandpa was happy to see me because __________.

A. he could discuss the problem with me

B. he had not seen me for a long lime

C. he was afraid of darkness

D. he felt quite lonely

【3】What can be inferred from the passage?

A. The grandchild was eager to leave.

B. They would have more chats.

C. The lights would go out again.

D. It would no longer be dark.
