26、My elephant adventures began in 1984 when, with our one-year-old daughter, my husband and I crossed the jungle in a jeep, slicking behind a lorry for comfort and company. The elephants standing like watchers on either side of the forest highway had us praying for our safety. One elephant made loud noise and angrily pawed (抓) the ground, warning us off. We raced away before they could attack.
It was wise to keep elephants at a distance. We heard stories of tourists whose jeeps were overturned, and a couple of photographers were killed because they moved too close. Elephants are misleading animals. They give people an impression of being quiet and kind, so tourists think it’s safe to picnic in the jungle (丛林). Yet angry elephants have knocked them down in seconds before they could take off.
Elephants might make life unpredictable and dangerous. It’s difficult for inexperienced environmentalists to even, begin to grasp this reality. I’ve heard city people say “ We humans are encroaching (侵害) on their forests.” But what’s the solution?
When a poor farmer borrows heavily to plant a crop, he’ll do anything to protect it His life depends on it Elephants ruining an about-to-be-harvested com field cannot expect to be welcomed like special guests. The battle between beast and farmer is violent.
Experts are working on solutions to human-elephant conflicts (冲突). Some are sure to fail to like the plans to build electric fences around human settlements. Elephants rapidly figure them out and come in, around and over them.
There are more questions than answers, for sure. But as my husband said, “More people die in car accidents every single day, in every city on the earth. But they won’t take cars off the roads, will they?” So we need to seek practical ways of preventing elephant accidents.
【1】What is the writer’s purpose in writing Paragraph 1?
A．To tell readers her family’s experience of elephant adventure.
B．To show readers elephants are angry and dangerous,
C．To introduce the topic of the whole passage.
D．To describe how her family keep away from elephants.
【2】Why do tourists think it is safe to picnic in the jungle?
A．They think elephants are quiet and kind.
B．They haven’t heard the stories of elephant killing people.
C．They like elephants too much.
D．They think they can race away in seconds.
【3】What docs a poor farmer do to protect his crop?
A．Welcome elephant like special guests.
B．Fight with elephants for his harvest.
C．Stop planting crops.
D．Depend on elephants for his life.
【4】What can we learn from the last two paragraphs?
A．It is a good idea to build electric fences around human settlements.
B．It is impossible to find a solution to settle human-elephant conflict.
C．We should first reduce car accidents to prevent elephant accidents.
D．It is our duly to protect elephants rather than kill them.
27、How to Improve Math Skills
Make math part of your life. Take the opportunity to put your math skills to work in new and different situations outside your normal routine.【1】For example, if, say, a sweater that's regularly$38 is on sale for 30% off, what is the sale price? Or if you plan to hike a new trail that's 7 miles long and it takes you 20 minutes to walk a mile, how long should you plan for your hike to take?
Make studying math a priority.【2】Doing so will help you avoid procrastinating(拖延)and make it easier to get into "math" mode(模式)instead of sitting and staring blankly at the math book for 10 minutes. After putting in your study time, reward yourself by doing something you enjoy. It will encourage you to get through your math work and help you associate it with something pleasurable.
Take a break every hour.【3】You won't be able to maintain necessary focus and you'll quickly tire yourself out. Instead, take a quick break to stand up, stretch, get a drink, or use the bathroom every hour.
【4】In math, each topic builds upon the next, so, much like reading, it's difficult to make forward progress if you haven’t mastered all of the necessary steps. If you're struggling with a particular idea or concept, don't skip it and move ahead.【5】
A.Solve problems neatly and completely.
B.Master one concept before moving on to the next.
C.Take the time to apply math in common situations.
D.Avoid trying to solve math problems in your head.
E.Don't try to work hard through four unbroken hours of math problems.
F.Instead, seek help from the instructor or the tutor until you've mastered the idea.
G.Set aside time to work on math at the same time and in the same place every day.
28、If you haven’t already, you too should switch to the latest eco-friendly, energy-efficient, energy-saving LED (Light Emitting Diode) lighting. As the world becomes more focused on green issues, everyone should do their part in practicing energy efficiency, recycling, cutting down their CO2 emissions and much, much more. One of the most successful campaigns that started in Australia is the now world-famous“Earth Hour”. 2.2 million of Sydney’s residents turned off their lights for an hour in a mass attempt to save energy. The following year, the same idea was adopted by a whole host of different cities.
This is a great example of a campaign to promote eco-friendly options and energy efficiency. But while it clearly raises awareness, it is not a long-term solution to energy saving across the developed world. A long-term solution can be found in the form of switching to LED lighting rather than the traditional halogen lights(卤光灯) found in a typical home.
Put simply, LED lighting is the future of lighting. LED lamps use up only a fraction of the energy pared to that of regular lamps. They also produce a quality flicker-free light, and will last longer than a regular light with 50,000 hours being realistic. Not only are they longer lasting and more energy-efficient with no sacrifice in light quality, but they may quickly become a possible substitute (替代物) for regular lamps that have been previously installed by homes and businesses.
An ordinary 50 watt low-voltage halogen light on for 4 hours a day would cost $ 25 per year to run. With a life span of around 3,000 hours it will typically stop working at the two-year mark. compared with the regular one, an LED light of 50 watts operating for the same period will cost roughly $ 6 per year to run and last 50,000 hours. That means it won’t have to be replaced for 24 years! It really is a no brainer to switch to energy-saving LED lighting. Plus, you will be doing your bit for the environment by being more eco-friendly.
【1】“Earth Hour”is held in the world every year in order to .
A.ask people to generate more energy for daily use
B.call on people to use less energy as much as possible
C.remind people to remember the days without lights
D.advise people to have a good rest after working hard
【2】 How should we save energy according to the author?
A.Raise public awareness.
B.Turn off the lights.
C.Hold“Earth Hour”.
D.Use LED lights.
【3】It can be inferred from the third paragraph that LED lamps .
A.are more expensive that regular ones
B.will take the place of regular lamps pletely
C.might be used by more homes in the future
D.use up more energy and give out more light
【4】The underlined phrase in the last paragraph“no brainer”probably means a thing that .
A.needs no consideration.
B.needs deep study
C.changes with others
D.connects with others
29、Cancer is a leading cause of death around the world. When it comes to cancer, the sooner you know you have it, the better your chances of surviving. A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide evidence to the early forms of the disease.
Scientists at Swansea University in Wales came up with the idea. Gareth Jenkins is a professor at the university. “ In this blood test we don’t measure the presence of cancer; we measure the presence of mutant red blood cells which are collateral(附属的) damage that occurs---a by-product of the cancer developing.”
The researchers used normal laboratory equipment to perform the test. This equipment looks for changes in the structure of millions of red blood cells. Those mutant cells lack a surface protein that healthy cells normally have. “The main purpose of the test is to look for very rare cells which have picked up a mutation. The number of mutant red blood cells in a healthy person is around 5 or so per million. You have to look at millions of red blood cells to detect those rare events. These numbers increase in cancer patients---they go up to 40 or 50 mutants on average.”
The researchers tested blood from about 300 people, all of whom have cancer of the esophagus(食道). Patients with esophageal cancer have high levels of mutant red blood cells. Jenkins says that at this point he is not sure if other cancers will produce similar results.
The hope is that the new test and other non-invasive methods could one day become part of commonly used medical methods. He says that using a battery, or series, of tests will be the best way to find out if a person has cancer. These new technologies could save millions of lives.
【1】According to the test, how do scientists find out if a person has cancer?
A．By calculating the speed of changes in the structure.
B．By observing the surface protein.
C．By looking for changes in the number of mutant red blood cells.
D．By measuring the presence of cancer.
【2】What does the underlined word “mutant” in the 3rd paragraph mean?
A．Decreased.
B．Changed.
C．Increased.
D．Multiplied.
【3】The author adopts a/an tone in the passage.

B．favorable
C．critical
D．objective
【4】In which section of a website can you most probably find the passage?
