C．have declared
D．were declared

答案　C
解析　句意为：——我要去圣弗朗西斯科几天。——我真羡慕你(I really envy you)。我多么希望我也可以离开一会儿呀。由句意知C项符合语境。It doesn’t matter没有关系；forget it别提了；I can’t agree more完全赞同。
8．I really don’t know________I had my money stolen.
A．when was it that B．that it was when
C．where it was that D．it was where that
答案　C
解析　由强调句结构“It was...that...”可排除B项；强调句作动词know的宾语，语序应为陈述句语序，排除A项。显然，强调句的强调部分为where，但是当强调句为宾语从句时，这类wh 连接代词或副词常置于it之前，作宾语从句的连接词。

Ⅱ.阅读理解
A
For many years，Hawaii has been a magic name to people who like to travel.People on both sides of the Pacific Ocean，in Japan and in America，dream of seeing these beautiful islands in the middle of the ocean.Their dreams always include at least one scene of a sunset over the ocean.In the tropical(热带的) lands，the sun drops，like a ball of golden fire，into the sea，and it drops so quickly that you can almost see it move.The sun leaves behind a glow that lights the skies and shines in the quiet water.
People often have a quiet，peaceful time—perfect for a leisurely(悠闲的) walk along the water.This scene is not too different from the dramatic(令人神往的) beauty that greeted the first strangers to these islands centuries ago.They were Polynesian people who came from Tahiti in canoes not much bigger than small boats.
They found the beautiful white sand beaches and the waving palm trees，but there were no giant hotels like the ones we see nowadays.The first people came to Hawaii nearly two thousand years ago，but skyscraper hotels were only built in the last 25 years.Now jet planes make it possible to fly to it for a weekend from Tokyo.Wherever the people come from，they really want to see the original beauty of Hawaii.They want to see the lovely beaches and the mountain called Diamond Head which is almost hidden by the tall hotels.
1．Hawaii is a name________.
A．given by people who like to travel
B．attracting a lot of travelers
C．with a magic story behind it
D．liked by both the Japanese and Americans
答案　B
解析　推理判断题。根据第一段可知，夏威夷是喜欢旅游的人向往的一个地方，故B项正确。
2．On these beautiful islands，one thing that every traveler won’t miss is________.
A．to swim in the quiet water
B．to see the tropical plants
C．to see the sunset
D．a leisurely walk along the beach
答案　C
解析　细节理解题。根据第一段“Their dreams always include at least one scene of a sunset over the ocean.”可知答案为C项。
3．Which of the following does not belong to “the original beauty of Hawaii”？
A．White sand beaches.
B．Waving palm trees.
C．Tall hotels.
D．The Diamond Head Mountain.
答案　C
解析　细节理解题。根据文章最后一段可知，高楼大厦是最近25年内建起来的。
4．The last paragraph suggests________.
A．the scenery nowadays is not too different from the original beauty
B．it’s not quite easy to see the original beauty，because some of the scenery is almost hidden by tall hotels
C．it is easy to see the original beauty，but only by taking jet airplanes
D．it is not easy to see the original beauty because things have completely changed in the last 25 years
答案　B
解析　推理判断题。根据文章最后一句“They want to see the lovely beaches and the mountain called Diamond Head which is almost hidden by the tall hotels.”可知，高楼大厦把部分美景给遮掩了。所以要看原始的美，不是很容易。
5．The best title of the passage is________.
A．Islands Scenery
B．Hawaii：A Magic Name
C．Traveling in Hawaii
D．The Dramatic Beauty
答案　B
解析　标题归纳题。根据文章内容可知本文主要讲了夏威夷的自然风光。A、D两项光看题目，是不会想到是在讲夏威夷的美；这里不是讲夏威夷旅游，排除C项。
B
Ashok Gadgil has spent the past three decades helping people in need—and he has no plans to stop.On May 2，Gadgil won the $100,000 Lemelson MIT Award.Each year，the honor is given to an inventor who has improved the lives of people in developing countries.Gadgil’s inventions have helped more than 100 million people around the world.
Gadgil is a professor and physicist at the University of California，Berkeley.When he’s not teaching，he works to find solutions to global problems such as energy efficiency(效率) and water safety.“I chose to focus on problems where my knowledge of science could help，” Gadgil said.
In the 1980s，he came up with a program to make energy efficient light bulbs more affordable for people in developing countries.Then in the 1990s，Gadgil designed his first life saving invention，UV Waterworks.It kills deadly disease carrying germs(病菌) from drinking water.It costs just one cent to clean five liters of water.Gadgil was inspired to find an inexpensive solution to the clean water crisis after more than 10,000 people in his home country of India died from an outbreak of Bengal cholera(霍乱)，in 1993.The disease is spread through polluted food and drinking water.
So far，the invention has provided safe drinking water to more than 5 million people in India，Liberia，Nigeria，the Philippines and Ghana.
Families in refugee(难民) camps in Sudan are given food aid.But they still have to cook the meals.In order to do so，refugee women leave the safety of the camps three to five times a week to gather firewood.They walk up to seven hours a day to find enough wood to fuel their stoves.Cooking over an open flame can be dangerous to one’s health and to the environment，too，because of the amount of smoke it causes.Gadgil visited the area many times with his students and his co workers to work with the refugee women on designing a clean，fuel efficient stove.The Berkeley Darfur Stove he created saves 55% of fuel.That means the women wouldn’t have to leave the houses to find firewood as often.The invention also helps to save homes more than $300 a year.About 125,000 women and their families have been helped.
As a professor，Gadgil encourages his students to stay positive about finding solutions to hard problems.“Be optimistic when you try a hard problem，” he says.“It’s when you solve a large problem that you can have a powerful effect on the world.”
6．Gadgil was given Lemelson MIT Award for ________.
A．his teaching experience
B．his new research report
C．his vast knowledge
D．his helpful inventions
答案　D
解析　细节理解题。根据第一段可知，Lemelson MIT Award是奖励给那些为改善发展中国家人民生活而进行发明创造的人。Ashok Gadgil也因此而获奖。
7．What can we learn about UV Waterworks
A．It’s Gadgil’s first invention.
B．It’s used to clean water.
C．It’s designed for India.
D．It saved 10,000 people.
答案　B
解析　细节理解题。根据第三段的“It kills deadly disease carrying germs(病菌)from drinking water.It costs just one cent to clean five liters of water.”可知，UV Waterworks是用来清洁饮用水。
8．Which of the following is TRUE of the Berkeley Darfur Stove
A．It takes women 7 hours to fuel.
B．It doesn’t cause any smoke.
C．It is clean and money saving.
D．It is equipped with fire alarm.
答案　C
解析　细节理解题。根据倒数第二段的“...a clean，fuel efficient stove.The Berkeley Darfur Stove he created saves 55% of fuel...The invention also helps to save homes more than $300 a year.”可知答案为C项。A项错误；B项太绝对；D项文章未提及。
9．According to the last paragraph，Gadgil encourages his students ________.
A．to learn lessons from failures
B．to find problems in peaceful life
C．to make inventions to help poor people
D．to be confident when facing difficulties
答案　D
解析　细节理解题。根据最后一段“...to stay positive about finding solutions...”可知D项正确。positive自信的，积极乐观的。
10．Which of the following can best describe Gadgil
A．Caring and determined.
B．Powerful and positive.
C．Independent and sensitive.
D．Responsible and strict.
答案　A
解析　推理判断题。Gadgil为挽救人们的生命及改善人们的生活发明了饮用水消毒装置和节能炉子，同时从20世纪80年代开始一直致力于解决全球性问题的发明创造，由此可推断他是一个意志坚定的人。
