26、For the third time in a week, Jodie, one of my students, refused me again. Passing my office door, she gave half-hearted wave and walked down the hall. Something was bothering her but I couldn't tell what. I thought it would pass. The next day when she all but ignored me again, a boyhood memory came to mind.
I was riding my bicycle, gliding, carefree, down the street, following a local political campaign, and stopping occasionally to pick up flyers and sweets the candidate (候选人) had thrown to the crowd. My fender (挡泥板) made a strange noise. One small part was holding it on. My father had warned me about it, but I didn't pay attention to his advice. “I’ll fix it later,” I had promised.
I was miles from home; I turned back, taking a short cut, even though I had to cross a four-lane road that I wasn't supposed to go near. I waited for a break in the traffic, then stood up and threw my weight onto the bike. Just as I was about to make it across, the fender broke and slid down over the tyre, blocking it like a doorstop under a door. The bike stood on its nose and I went flying over the handlebars. I fell on to the rough pavement and slid for about six feet. I rolled over to see the cars and trucks thundering towards me. I dragged myself to the edge of the road. For a long time I lay there. My hands and the skin of my stomach were very painful.
All these years later I remember my father's words Better fix that before it gets too bad to fix. Small problems grow into big ones if they aren't attended to. Good relationships could unravel if conflicts aren't dealt with. So, the next time I saw my student Jodie, I asked her, "Can you come over to my office?" We needed to talk.

27、The latest thing in architecture is green buildings—covering walls and roofs with a carpet of plants to prevent heat, absorb rain and provide a home for wildlife. Many such buildings need complex systems for holding and irrigating the soil.【1】
Ivy is a group of evergreen climbing plants, whose power to live is hard to beat. Firstly, it can live in almost any surroundings, whether in shade or full sun.【2】It grows well in both dry and damp soil. Moreover, it doesn't need supports as it grows aerial roots that can be attached to most things. For these reasons, ivy can be widely grown to beautify an ugly wall or a fence.【3】It is a heaven for bees and butterflies in summer and its berries are a valuable food source for birds in winter.
However, there are some concerns about growing ivy. Ivy has a reputation for damaging buildings, but according to the UK's Royal Horticultural Society, this doesn't usually happen unless the walls already have cracks.【4】But Blanusa at the University of Reading, UK, who has examined the effects of plant climbers, finds that ivy raises humidity next to the wall by only a small amount.
【5】Once ivy has been in the ground for a few years, it can grow out of control. Just don't let it get the better of you.
A．Growing ivy can bring added benefits.
B．Therefore, I strongly oppose growing ivy.
C．The other fear is that it can make walls damp.
D．Besides, it can be tolerant of various kinds of soil.
E．Anyway, you do need to be careful in growing ivy.
F．An ivy-covered wall will slightly warm a room in winter.
G．However, there is a much easier approach: growing some ivy.
28、It took 100 years, but finally, scientists, from CalTech, MIT and the LIGO Scientific Collaboration, proved Albert Einstein's theory that gravitational(引力的) waves exist. The waves were predicted as part of Einstein's General Theory of Relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the Universe. For example, two black holes crashing into each other.
What are these gravitational waves? Well, imagine throwing a rock into a pond. When the rock hits the flat surface of the water, it creates ripples or waves. Space time is like the surface of the water. So that means gravitational waves are like the ripples moving out from where the rock hits the water. It might be hard to understand, but those gravitational waves expand and contract space and time as they move through space. And when they get to the Earth, the waves pass through, and contract and expand the planet as the wave goes by.
It was Einstein who said these gravitational waves should be observable. But these are not huge waves. They are very, very small, which is why it took so long to find them. You cannot see them with your eyes. They are smaller than the size of an atom.
How did the scientists find them? For years, scientists have been watching two black holes in another galaxy faraway with the help of the Laser Interferometer Gravitational-Wave Observatory. The two were spinning around each other, moving closer and closer together. When they finally crashed into each other, it was with such power and force, that gravitational waves rang throughout the universe, like a giant bell. Those waves, traveling at the speed of light, finally reached the Earth, some 1.3 billion years later. They are the same waves that the scientists announced this past week.
The National Science Foundation tweeted that each of the black holes was thought to be 29 to 36 times the mass of our sun. So, what does this discovery mean? Abhay Ashtekar, a Penn State physicist, who was not on the discovery team, said: "Our understanding of the heavens changed dramatically."
【1】According to the 1st paragraph, we can learn that_______.
A. gravitational waves were part of Einstein's General Theory of Relativity
B. scientists proved that gravitational waves existed 100 years ago
C. gravitational waves were the theory of the physics behind the universe
D. gravitational waves result from two black holes crashing into each other
【2】From the passage we can know that the gravitational waves______.
A. are not supposed to be observed.
B. are very huge.
C. are easy to be found.
D. can’t be seen with our eyes.
【3】Why did scientists spend years watching two black holes?
A. Because they wanted to see how the two black holes crashed into each other.
B. Because they wanted to find the gravitational waves.
C. Because they wanted to see the gravitational waves reach the Earth.
D. Because they wanted to know how black holes formed.
【4】What can we infer from the passage?
A. The discovery has no relation to Albert Einstein's theory
B. Throwing a rock into a pond can generate gravitational waves
C. The discovery will considerably affect people’s understanding of universe
D. gravitational waves can’t contract and expand the Earth
29、Casablanca：Time Did Go By
If the Hollywood image of Casablanca is important to you, prepare for a shock from Casablanca.The city is further away from eastern romanticism (浪漫主义）than any other in Morocco，and Casablanca is a modern city — and beautiful in its own aspect.
Colony(殖民地）White
A walk around Casablanca will decide clearly that Casablanca was the place that the French colonial government gave most attention and money.The buildings are of a French version (版本）of Arabo-Andalucian architecture，white with soft lines，and often plenty of details.
The area to explore is south of Avenue des Forces Arms Royales，but of special interest is the Place des Nations Unies，which has the largest structures.
Town Market
Right in from the long Boulevard Muhammad 5, you will find the Marche Central of Casablanca.The place is a small but high-quality version of the traditional suuqs of Morocco, and everything is aiming at the needs of the locals.
The Marche Central has vegetables，meat，all kinds of sea food，as well as handicrafts (手工艺品）.Turtle soup should therefore be an option for those visiting Casablanca.
Old City
The old city of Casablanca is conveniently located — just off the main town square from where roads lead to all directions, and off the sea.But as you enter, you will see that it is not all that old after all，that the houses here often have a form and size which would have made them natural features in the new parts of many other Mococcan cities.
【1】Which of the following colonial governments put most money into Casablanca?
A.Moroccan. B.French. C.American. D.Arab.
【2】If you want to enjoy sea food，which would you like to choose?
A.Colony White. B.Old City. C.Town Market. D.Casablanca Time.
【3】What’s the writer’s attitude towards Casablanca in this passage?
A.Passive. B.Appreciative. C.Disappointed. D.Indifferent.
30、Ecotourism is a combination of ecology (the study of systems of living things) and tourism. It is defined as “responsible travel to natural areas that preserves the environment and improves the welfare of the local people” by the International Ecotourism Society. Actually, ecotourism can mean travel to far-off places of great natural beauty, but not always in a(n) _______ way. It's a big business, and the attraction of money can cause people to think about profits first. While ecotourism offers benefits to people and ecosystems, it leaves ecosystems _______ to negative effects, too.
Costa Rica, once a Spanish colony, and independent since 1821, has an ecotourism industry worth over one billion dollars yearly, and thousands of jobs have been _______. Nearly 21 percent of the land is now protected national parks, _______ thanks to ecotourism. Nevertheless, due to the number of people visiting the country's natural places, some damage to the ecosystem has occurred.
While tourists can have a negative impact on ecosystems, the same areas might have been _______ by industries such as farming, logging, or mining if there were no ecotourism industry. Shelters have been created instead, keeping the ecosystem protected. And, by visiting beautiful rain forests and seeing rare animals, visitors get a sense of their _______, and of gratitude for them. Tour guides can also be educators who train people to love and care for the environment. Visitors can take these lessons with them to their home countries.
Unfortunately, while their effect may not be _______ in the off-season, the constant parade of visitors in the high season can be damaging. At one national park in Costa Rica, wild monkeys now feed on garbage left by the tourists. In addition, ecotourists tend to seek out places with the rarest animals and plants, _______ the most delicate living things.
It is easy to be critical of the ecotourism industry, but it is important to be _______ as well. Ecotourism can never be “pure”. We can't expect zero negative effects on the ecosystem. It is also ________ to suppose that humans won't go anywhere accessible to them. If protection efforts are maintained and increased, those remaining places of undisturbed nature may be stressed, but they won't be destroyed.

32、Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
The dangers of safety
Travelling by road is widely accepted as being the most dangerous way to travel with far more deaths per kilometer than rail, sea or air. In fact, while road traffic injuries represent about 25% of worldwide injury-related deaths, deaths on the road in the UK have been decreasing for some time. We take a look at why the number is decreasing, but why it seems impossible to avoid deaths completely.
Over the years, different methods of reducing the number of crashes have been tried. The Locomotive and Highways Act of 1865 introduced the idea of speed limits to the motoring world. Since then, more and more ways of controlling the behaviour of drivers have been introduced such as one-way streets and traffic signals as well as compulsory driver testing and licensing. These days, there are many more methods of enforcement, including speed cameras and fines for breaking motor laws.
Another solution is to make cars themselves safer in case of an accident. This means the main focus has been on passive safety or crash survival rather than active safety or avoiding crashes. There are many innovations by motor manufacturers, which have made cars safer, such as seat belts, anti-lock brakes and airbags. These improvements have tended to make the driver feel more in control and isolated him/her from the fast-moving and dangerous environment outside the car. It seems strange that as improvements have been made the number of crashes continues to increase.
Actually, it is wrong to talk about safe and dangerous cars in this way. The key to this problem is not actually the car, but the driver. In fact, making drivers feel safer is not the solution to the problem, but it is the cause of the problem. As drivers feel safer, it encourages them to drive aggressively and to ignore other road users and therefore increases the number of crashes
