Islands in the world are famous for different things. But Hawaii is special for its variety of features. Beautiful sandy beaches, active volcanoes (火山), a great canyon (溪谷) and special history and culture add up to create its famously romantic atmosphere.

Formed by volcanoes at the bottom of the sea, the Hawaii islands are like a necklace in the middle of the Pacific Ocean, 6, 000 kilometers off the west coast of Mexico. There are eight main islands in the group, including Hawaii (or Big Island), Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau.

The youngest and biggest island, also called Hawaii was formed 430, 000 years ago and is still growing. Kauai, the oldest was formed 5.1 million years ago. For tourists, the sight of the lava (溶岩) that still flows from some of the volcanoes down to the sea, is a major attraction.

Hawaii is the newest and smallest state in the US. In 1900, the islands joined the US. In modem history, it will always be remembered for the attack on Pearl Harbor by the Japanese air force in 1941.

About 1, 000 years ago, the islands were settled by Polynesians (波利尼西亚人), Captain James Cook led the first group of Westerners there in 1778.

Native Hawaiians have a special culture and language. Although nowadays English is the official language of Hawaii, folk music and dancing are still widely practiced. The traditional dance of the islands is the hula, a Hawaiian word that means dance.

Hawaii's reputation for romance was spread when Hollywood started to use its typical music in movies in the 1960's.

Today, Hawaii is famous for its mix of cultures. Chinese, Japanese and Filipinos all live there. Chinese arrived in the islands as early as the late 18th century. Dr. Sun Yat-sen, the famous Chinese revolutionary, grew up there.

Everyone in Hawaii is a member of an ethnic minority (少数民族) and generally they exist in a pleasant harmony (和谐)of races and cultures.

1.Which of the following about Hawaii is NOT true?           

A. There are eight main islands in the group Hawaii islands.

B. Hawaii islands are like a necklace in the middle of the Pacific Ocean.

C. Hawaii islands are formed by volcanoes on earth.

D. Hawaii is the smallest and youngest state in the US.

2.What can we infer from the passage ?

Using 1900 as a starting point, here's a look at some of the most powerful and destructive hurricanes in the last 120 years in the US.

Most powerful hurricanes

Hurricane Camille, which landed on August 17, 1969 near Waveland, Mississippi, is the most powerful storm to strike the Gulf Coast. Camille is one of the four category(级别)-5 hurricanes ever to make a landing in the US, the others being the 1935 Labor Day Hurricane, Hurricane Andrew in 1992 and Hurricane Michael in 2018.

According to the National Weather Service, the actual wind speed of Hurricane Camille might be around 175 mph along the coast.

Until the arrival of Hurricane Katrina, Camille's more than 24-foot storm wave in Pass Christian, Mississippi, held the record. Katrina's storm wave along the Mississippi coast reached 30 feet.

Costliest hurricanes

Hurricane Katrina is not only the costliest-ever US hurricane but also the most expensive natural disaster in the country's history. Not only did it cost as many as 1,836 lives and leave millions of people homeless, but it also caused $ 160 billion in damages.

Katrina landed near the Gulf Coast on August 29,2005 as a category-3 storm. The hurricane's record-breaking waves flooded 80% of the city.

Deadliest hurricanes

The category-4 Hurricane Galveston made a surprising landing along the Texas coast on September 8,1900. It caused a 16-foot storm wave and its wind speed reached 150 mph.

A large part of the city of Galveston, Texas, was left in ruins. The number of death reached 12,000 on Galveston Island and the mainland. It remains the deadliest weather disaster in the US history as it gave the people no time to move out.

2.Which is the costliest hurricane in the US?

       In order to encourage students take outdoor activities, our school organized a mountain-climbing activity at July 10th. Hundreds of us took the part in it. It was a nice day. At 8:00, we gathered at the foot of Jinyun Mountain to set out for the top in high spirits. Along the way, we chatted, sang and laugh, enjoying the fresh air and beautiful sceneries. When some students fell behind, other would come and offer help. About 2 hours late, we all reached the top. Bathing in the sunshine, the distant city looked fantastic but we jumped and cheered with joy.

       This activity benefited us a lot. Not only did it get us close to nature and give us relaxation from heavy homework, but it also promoted friendship among us. What wonderful a trip it was!

2.考查推理判断。根据第一段中的“Beautiful sandy beaches, active volcanoes (火山），a great canyon (溪谷) and special history and culture add up to create its famously romantic atmosphere.”美丽的沙滩、活火山、大峡谷以及独特的历史和文化，造就了它著名的浪漫氛围；以及第七段“Hawaii's reputation for romance was spread when Hollywood started to use its typical music in movies in the 1960's.”20世纪60年代，当好莱坞开始在电影中使用夏威夷的典型音乐时，夏威夷的浪漫名声就传开了。可推知，夏威夷是著名的旅游胜地。故选D。

V.【答案】 C；F；A；B；G  

【解析】本文是一篇说明文，自然灾害是可怕的事情，当孩子们表现出对自然灾害的恐惧时，文章介绍了五个方法来帮助孩子们减少恐惧。

 （1）考查对上下文的理解和推理判断能力。根据第一段可知，根据空后“But talking can help children feel safer and less afraid of the future.”但是交谈可以帮助孩子们感到更安全，对未来少一些恐惧，可知，C选项中的talking以及natural disasters符合本段主题，且和下文呈转折关系，故选C。

 （2）考查对上下文的理解和推理判断能力。根据空前的“When children are allowed to talk about their fears, they feel safer. Sometimes, the best thing an adult can do is just listen.”当孩子们被允许谈论他们的恐惧时，他们会感到更安全。有时候，成年人能做的最好的事情就是倾听，可知，F选项中的fear和listen与前文关键字相契合且内容（无论恐惧是什么，重要的是倾听和耐心对待孩子）与前文呼应，故选F。

 （3）考查对上下文的理解和推理判断能力。根据文章结构可知，可知空处是段落的主旨句。再根据空后内容可知，A选项questions和后文内容相契合，且顺承下文内容“When answering their questions, it is best to give short, honest answers. If you do not know the answer, you can be honest and say that you do not know.”在回答他们的问题时，最好简短、诚实地回答。如果你不知道答案，你可以诚实地说你不知道，故选A。

 （4）考查对上下文的理解和推理判断能力。根据空后可知，one way和B选项中ways相契合，B. There are many ways to do this.“由很多方法可以做到这一点”承接下文，故选B。

 （5）考查对上下文的理解和推理判断能力。根据空前“However, she loved to write.”然而，Heshani 喜欢写作；以及空后“Writing poems was a way for her to share her fears since she did not like to talk about them.”写诗是她分享恐惧的一种方式，因为她不喜欢谈论它们，可知，G. And she often shared her feelings about the tsunami in her poems.“她经常在她的诗歌中分享她对海啸的感瘦”是并列关系，且承接下文，故选G。

 【点评】本题要求在理解细节信息的基础上，着重考查对上下文的理解和推理判断能力。
