【題目】—How many parents have you invited to our class meeting this time?

—Ten. I gave all of them invitations. But I’m not__________if all of them will come.

A.seriousB.sureC.ready

【答案】B

【解析】

句意：——這次你邀請了多少家長參加我們的班會？——十個。我給了他們所有的邀請。但我不確定他們是否都會來。

考查形容詞辨析。serious嚴(yán)肅的； sure確定的； ready準(zhǔn)備好的。根據(jù)“if all of them will come.”可知這里是不確定用be not sue。根據(jù)題意，故選B。

【題目】 You might have learned in your science classes that the sun is quite large and heavy. What if you heard that we’ve found a black hole that contains the mass (質(zhì)量) of nearly 70 suns?

Chinese scientists used LAMOST, a powerful Chinese telescope (望遠(yuǎn)鏡), as well as telescopes in Hawaii and the Canary Islands, to make this discovery.

According to Einstein’s theory, black holes come from dying stars. The star collapses (坍塌) into a small point with a lot of mass and strong gravity (引力). The strong gravity of the black hole allows it to pull other things in and “eat” them. Scientists search for black holes by looking at x-rays that are released when they “eat” nearby stars. However, when black holes are inactive, this method doesn’t work.

This time, the researchers looked at stars that orbit invisible (看不見的) objects. These objects, they believe, cannot be anything but black holes. After calculating (計算) the speed of one particular star in a star system named LB-1, the scientists figured out that it was orbiting (繞軌道運(yùn)行) a stellar-mass black hole.

The black hole’s mass is about 70 times the mass of our sun. According to current theory, this black hole shouldn’t even be able to exist. It was previously believed that the mass of such a black hole cannot be bigger than that of 25 suns. Stellar (星球的) winds blow away the heavy elements that are left behind when a star dies. But somehow, this black hole kept most of its heavy elements.

Researchers said it is possible that the black hole formed out of two large stars that died and merged (結(jié)合) together.

The discovery is also inspiring some researchers to revisit their previous studies. “This discovery forces us to re-examine our models of how stellar-mass black holes form,” University of Florida physicist David Reitze was quoted as saying in a press release.

【1】How did Chinese scientists find the stellar-mass black hole?

A.By looking at stars moving away from the black hole.

B.By studying x-rays that came from the black hole.

C.By calculating the gravity of a nearby black hole.

D.By looking at the speed of a star that orbits it.

【2】What does the underlined word “inactive” mean in Chinese?

A.積極的B.不活躍的C.快速的D.活潑的

【3】What do we know about the black hole?

A.It is much heavier than the sun.B.It is moving faster than the sun.

C.It hasn’t “eaten” any stars.D.It will disappear soon.

【4】What is the last paragraph about?

A.The importance of this discovery.

B.Previous studies on black holes.

C.The formation (形成構(gòu)成) of stellar-mass black holes.

D.The preparations that were done before making this discovery.

【5】What do we know from the story?

A.Black holes are usually heavier than 25 suns.

B.We cannot believe current scientific theories.

C.Black holes can form after stars die.

D.Stellar-mass black holes contain no heavy elements.

【題目】 In order to protect environment, it is very important to learn about the environment. There are many ways to understand how to protect the environment, such as reading books, asking someone and so on. You are students. In your spare time, you can read as many as books. Books in the library are worth reading. They will help you learn. Ask your classmates or librarians for some suggestions. They have good ideas. You can also get information about the environment on some good websites. Besides these, I have some suggestions.

In our everyday life, some people use less energy by carpooling. For example, three or four persons can ride together in one car instead of driving three or four cars to work. Usually it is time-saving and convenient to carpool with their neighbors to take their children to school. Whenever we use electricity, we should turn off lights, the TV, the computer and so on when we don’t use them. On the other hand, we should use energy-saving products. Some products, like environment-friendly new energy cars, are made specially to save energy. These cars can travel longer than ordinary cars. They produce less pollution, too. Some products like computers and TVs with the ENERGY STAR label （標(biāo)簽） are made to save energy. The products with these labels will help us protect the environment.

Secondly, we should buy recyclable products instead of non-recyclable ones. Recyclable products usually take less energy. When we go shopping, pay attention to the recycle mark on the package: make a circle and three arrows.

根據(jù)材料內(nèi)容，選擇最佳答案。

【1】The passage is mainly written for .

【題目】 US writer Margaret Lee Runbeck once wrote, Happiness is not a station you arrive at, but a manner of travelling. But travelling is not always happy, at least for the buddies in the movie green Book. The popular film won Best Picture at the 91st Academy Awards on Feb 25.

The movie was adapted from the true story of a road trip through the southern US in the early 1960s. In the film, the black pianist Don Shirley hires Italian-American Tony Vallelonga to drive him to performances, but they face problems because of Shirley's skin color. These problems lead them to form a special friendship.

“There's something so deeply right about this movie, so true to the time,” wrote US film critic Mick LaSalle. The time La Salle is talking about was between late 1870s and 1960s, a very different period in US history. Many parts of the country had Jim Crow laws, which allowed racial segregation(種族隔離).

These laws made life and travel dangerous for African-Americans. They couldn't use certain hotels, restaurants, or even gas stations. They had to be indoors after sunset or they might go to jail. Even black celebrities had to follow the laws.

But in 1936, a black postman named Victor H. Green made a list of friendly businesses in New York City. He published the list as a small book with a green cover. The Green Book helped African-Americans travel more safely. Then, in 1964 ,Jim Crow laws went away. The book went away, too.

Today many US people still remember the time of Jim Crow. But they probably don’t know about The Green Book. It's a forgotten part of the story. Thanks to this movie,maybe people can remember it again.

【1】The story in the movie happened_________in the US.

A.in1936B.in the early 1960sC.In1964D.in the late 1870s

【2】According to the Jim Crow laws, African-Americans_________.

A.could stay in any hotel they like

B.needn't follow the laws if they are famous people

C.could not hang out with friends at midnight

D.couldn't work with the white people

【3】To help African-Americans travel more safely,_________made the Green Book.

A.a black celebrityB.a black pianist

C.a black postmanD.an Italian-American driver

【4】The film is mainly about_________.

A.a dangerous and terrible trip of a pianist

B.a special friendship between a pianist and a driver

C.how to travel more safely in the southern US

D.a different period in American history

【題目】 I got to the house, but no one came out. I got out of the taxi, walked up to the door, and knocked.

“Just a minute,” answered someone. After a long time, the door opened. A small old woman stood before me. I took her bag and let her take my arm. Then we moved slowly to the taxi. She kept thanking me for my kindness. “It’s nothing,” I told her. “I just try to be nice to my passengers, because I want others to be nice to my mother, too.”

When we got in the taxi, she asked, “Could you drive through the city?” “It’s not the shortest way,” I answered. “Oh, just do it,” she said. “I’m on my way to a hospice（安養(yǎng)院）. I don’t have any family left.” For the next two hours, we drove through the city. She showed me a building—she and her family once lived there. Sometimes she asked me to drive slowly in front of some buildings, and she would look at them and say nothing.

We got to the hospice. I took her bag to the door. “How much should I pay you?” she asked, “Nothing,” I answered. Without thinking, I gave her a hug. “You make an old woman happy,” she said. “Thank you.”

I didn’t have any more passengers that day. I just thought about that woman. I’m happy that I helped her. It was a small thing, but it was a great moment in life.

【1】What is the author?

A.A doctor.B.A policeman.C.A taxi driver.D.A volunteer.

【2】Why did the old woman ask the author to go that way?

A.She wanted to visit her family in the city.B.She wanted to run away from the hospice.

C.She wanted to see things about her past life.D.She wanted to have more time with the author.

【3】What do we know about the old woman?

A.She had no money.B.She walked slowly.

C.She was the first passenger that day.D.She didn’t want any help.

【4】How did the author help the old woman?

A.He took the bag for her.B.He gave her some money.

C.He cared for her family.D.He found her a better home.
