【题目】Overloaded with work, school teachers now get far less sleep than they ______.

A. shall B. should

C. may D. might

【答案】B

【解析】

试题分析:本题主要考查情态动词。

A项,shall “会;将;必须”,用于第二、三人称时,表示说话人给对方的命令,警告,允诺或威胁;

B项,should “应该;就;可能;将要”;

C项,may “可以,能够;可能,也许;祝,愿;会,能”;

D项,might “可以;或许;应该”。

根据句子大意可知,这里指“他们本该有的睡眠时间”,表示“应该”,故排除A、C项;D项 might 作“应该”之意时,语气较为缓和,常常翻译为“不妨...”,不符合句意。故正确答案为B。

【题目】阅读下列短文,从每题所给的ABCD项中,选出最佳选项,并在答题卡上将该项涂黑。

Imagination and fantasy can play an important role in achieving the things we fear. Children know this very well. Fred Epstein ,in his book If I Make It to Five, tells a story he heard from one of friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operations and a lot of pain by mastering his imagination.

Tom loved to pretend, and he particularly loved to play superheroes ,Dr. Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led.

The day before his third trip to the operating room, Tom was terribly afraid. ”Maybe I could go as Superman ,”he whispered to his mom. Hearing this, the mother hesitated for a while. She had avoided buying the expensive costume(戏装),finally she agreed.

The next day Tom appeared as the powerful Superman, showing off through the hospital halls and coolly waving his hand to the people greeting him along the way. And Tom, with the strength of his fantasy, successfully made it through the operation.

The power of imagination need not be reserved for children only.

【题目】Auckland is New Zealand’s largest urban area with a population of just over a million people. It is not, however, the capital, although it was at one time, until the capital moved to Wellington. Auckland is the center of commerce and industry, and is perhaps the most energetic, prosperous and multicultural city in New Zealand.

The city’s landscape is decided by volcanic hills, the twin harbors, bays, beaches and islands. Its nickname “the city of sails” is very suitable. Auckland has more boats for each person than anywhere else in the world.

Auckland has many volcanic hills, many of which currently afford great views of the city. And Auckland’s geography is such that shiny waters seem to attract people from every point. It is a water lovers’ best place, with some of the best beaches, swimming, diving, fishing, sailing, windsurfing and water sports in the country.

Wellington is the capital city of New Zealand. It is also the cultural, administrative and political center of the country. Two aspects of the city that will immediately strike any visitor are the harbor and hilly landscape. Everywhere you go, the sounds and the smell of the ocean hang in the air, and green hills and valleys wrap you in a bear-hug embrace. At night, Wellington offers a spectacular, shimmering(闪闪发光的) cityscape that is unlike almost anywhere else in the world. Even after seeing it for a hundred times, it takes your breath away.

Wellington is a scenic, windy and diverse place. It has some of the best museums, art galleries, restaurants, and coffee houses in the country. It is the storehouse for the nation’s historic, cultural and artistic treasures. Being the first place where European settlers arrived, it also boasts lots of historic streets and buildings.

Wellington is host to an excellent Festival of the Arts every two years.

1What would be the best title for the passage?

A. The Landscape of New Zealand B. The Capital of New Zealand

C. Auckland and Wellington D. Welcome to New Zealand

A. study New Zealand culture B. see green hills

【题目】The biggest challenge faced by travelers especially those who like to have a hiking trip is how to ensure a steady supply of clean clothes. Now, thanks to a great invention called Scrubba Wash Pack, that worry may be a thing of the past.

The portable(手提的) washing machine was invented by Ash Newland in 2010, while planning to climb Mt. Kilimanjaro. Struck by the limited packing space, he got inspiration(灵感) from traditional washboards to create a bag that could be used to clean clothes. Then he gave up his career as a lawyer and focused on perfecting the bag’s design. By 2012, the bag was ready for the public. It weighed only 180 grams and required very little storage space, making it perfect for anyone wishing to travel light.

Not surprisingly, the bag worth 55 dollars was an instant hit with travelers, university students and even passengers. However, Newland was not satisfied. He still saw a flaw(缺点) with his invention – dirty clothes had to be carried around in a separate bag! The recently introduced Scrubba Wash Pack solves that problem.

In order to make the pack active, dirty clothes are placed inside the bag along with two to three liters of water. The bag is then shut tightly to ensure all air is squeezed out(挤出去) and the clothes are massaged for a few minutes. After a quick wash, they are clean and ready to be dried. According to Newland, the pack can clean anything from jeans to smelly socks! What’s even more amazing is that with a capacity to hold 13-liters of water, it can be used to wash more clothes at a time.

The best part is that the 99-dollar pack that will be available for sale later this year, only weighs 300 grams and is completely foldable, making it easy to store when it’s not in use. With the Scrubba Wash Pack, wandering through foreign cities searching for a washing shop, or paying for washing machines may soon be a thing of the past!

1What led Ash Newland to create the Scrubba Wash Bag?

A. His job requirements. B. His personal experience.

C. His interest in invention. D. A traditional washboard.

2Why wasn’t Ash Newland satisfied with his former invention?

A. The invention was not so convenient.

B. Clothes couldn’t be washed well.

C. The bag couldn’t contain enough water.

D. The cost of the invention was very high.

3It can be inferred that the improved Wash Pack ______.

A. turns to be much environmentally friendlier

B. will replace the traditional washing machines

C. can encourage more people to travel a long distance

D. will be widely used by more travelers in the future

4What is the passage mainly about?

A. Introducing a great new invention.

B. Explaining the development of backpack

C. Listing some common problems for travelers.

D. Comparing two kinds of washing machines.
