The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different，any changes the scientist observes in a demonstration(实证)must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein，who developed the Theory of Relativity，arrived at this theory through mathematics. The accuracy(正确性)of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(计算)that may test his investigations.

| A．The tools he uses. | B．His ways of learning. |
| C．The way he uses his tools. | D．The various tools he uses. |
| A．the importance of information |
| B．the difference between scientists and ordinary people |
| C．the importance of thinking |
| D．the difference between carpenters and ordinary people |
| A．works under one set of conditions at one time and also works under the same conditions at other times |
| B．doesn’t allow any change even under different conditions |
| C．leave no room for improvement. |
| D．can be used for many purposes |
| A．Scientists are different from ordinary people. |
| B．The Theory of Relativity. |
| C．Exactness is the core(核心)of science. |
| D．Exactness and way of using tools are the keys to making of a scientist. |
答案
小题1:C
小题2:C
小题3:A
小题4:D
解析
试题分析：是什么品质成就了一名科学家呢？是他学习的方式还是学习的工具使他与众不同呢？答案是否定的。科学家之所以能成为科学家，不是因为他们使用的工具不同，而是因为他们使用工具的方式不同； 此外作为一名科学家，他们提供的理论必须是精确严密的。
小题1:C细节理解题。由文章第一段It isn’t the tools a scientist uses but how he uses these tools which make him a scientist.可知一个人之所以能成为科学家不在于他所使用的工具，而在于他如何使用这些工具。故正确答案为C。
小题2:C推理判断题。根据句中的how可知如何去调查，如何去发现都需要运用人的思维能力，这些都是人们努力思考的结果，由此推断作者说这些话的目的是想说明思考的重要性，故C为正确选项。
小题3:A细节理解题。根据文章第二段What works under one set of conditions at one time must work under the same conditions at other times.可知科学理论指的是可以在一系列条件下面行得通的东西，必须在别的时候也可以在同样的条件下行得通，所以答案选A。
小题4:D主旨大意题。文章开头以设问方式提出中心What makes a person a scientist？然后在两段中分别介绍科学家所应该具有的品质，即如何使用工具和知识的严谨精确，由此可知D为正确选项。

Explore your library. Visit your local library to borrow books and magazines that your kids haven’t seen before. Many libraries have summer reading programs, book clubs, and reading contests(比赛) for even the youngest borrowers. With a new library card，a child will feel extra grownup by borrowing books.
Read on the road. Going on a long car trip？Make sure there are some books at the back seat. When you stop driving，read the books aloud. Get some audio books in libraries and listen to them together during driving time.
Make your own books. Pick one of your family’s favorite parts of summer—whether it’s baseball，ice cream, or the pool—and have your child draw pictures of it or cut out pictures from magazines. Stick(粘贴) the pictures onto paper to make a booklet(小册子)and write text for it. When you’re done，read the book together. Reread it whenever you like!
Keep in touch. Kids don’t have to go away to write about summer vacation. Even if your family stays home，they can send postcards to tell friends and relatives about their adventures(冒险经历). Ask a relative to be your child’s pen pal and encourage them to write each week.
Keep up the reading habits. Even if everything else changes during the summer，keep up the reading habits around your house. Read with your kids every day—whether it’s just before bedtime or under a shady tree on a lazy afternoon. And don’t forget to take a book to the beach！Just brush the sand off the pages — it’s no sweat!

Organic mulch improves the condition of soil. As the mulch breaks down, it provides material which keeps the soil from getting hard. This improves the growth of roots and increases the movement of water through the soil. It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants. It also provides good environment for earthworms and other helpful living things in the soil.
It is easy to find organic mulch materials. Cut-up leaves and small pieces of tree bark can be used. Grass cuttings are also a good mulch for plants. Mulch from news- papers works well in controlling weeds.
The best time to add mulch depends on your goal. Mulch provides a thick barrier between the soil and the air. This helps to reduce temperature changes in the soil. As a result, mulched soil will be cooler than other soil in the summer. In winter, the mulched soil may not freeze as deeply as other soil. The best time is after the ground has frozen, but before the coldest weather arrives. Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter. Delaying the spreading should prevent this problem. The animals will probably find another place to live.
小题1:The author tells us the following EXCEPT ______.
| A．what mulch is and its advantages |
| B．the best time to add mulch |
| C．the bad effects of mulch |
| D．what can be mulch on the soil surface |
| A．tree barks | B．plastic | C．grass cuttings | D．cut-up leaves |
| A．improve the condition of soil |
| B．improve the ability of the soil to hold water |
| C．provide a good environment for earthworms |
| D．improve the growth of roots and increase the movement of water through the soil |
| A．the best time to add mulch is in spring and summer |
| B．the best time to add mulch is after the coldest weather arrives |
| C．the best time to add mulch is exactly the same time of each year |
| D．choosing the best time to add mulch can avoid attracting small animals |
Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on the surface reaches a peak then falls. But explaining a clear connection to weather is harder.
“Our research confirms the observed connection between solar change and regional winter climate,” lead author Sarah Ineson of the UK Met Office told the reporters in an email. The study was published in the magazine Nature Geoscience on Monday.
The researchers found that the reducing of ultraviolet(UV，紫外线) radiation from the sun can affect high-altitude wind patterns in the Northern Hemisphere(半球), causing cold winters.
“While UV levels won’t tell us what the day-to-day weather will do, they show us the bright future of improved forecasts for winter conditions for months and even years ahead. These forecasts play an important role in long-term possibility planning,” Ineson, a climate scientist, said.
Ineson and colleagues from Imperial College London and the University of Oxford used satellite data that more accurately(精确的) measures UV radiation from the sun and found a much greater change than previously thought.
They found that in years of low activity, unusually cold air forms high in the atmosphere over the tropics. This causes a redistribution(重新分配) of heat in the atmosphere, making easterly winds that bring freezing weather and snowstorms to northern Europe and the United States and milder weather to Canada and the Mediterranean.
When solar UV radiation is stronger, the opposite occurs.
More study was needed, though. A key uncertainty in the experiment lay in the satellite data used, because it covers only a few years. “So questions remain concerning both accuracy(精确) and also applicability to other solar cycles,” she said.
小题1:The new finding claims cold winters in the North Hemisphere can be caused by ______.
| A．a sharp rise in the amount of sunspots |
| B．a drop in the sun’s UV radiation |
| C．a complex computer model simulation |
| D．a clear link between the sun and the earth |
| A．UV radiation can affect high-altitude wind patterns |
| B．there’s a clear connection between the sun’s activity and weather |
| C．the sun’s radiation reaches a peak every eleven years |
| D．they can predict day-to-day weather conditions from UV levels |
| A．Canada and the Mediterranean will have milder weather. |
| B．The whole Northern Hemisphere will suffer from extreme winter days. |
| C．Freezing cold weather will appear in northern Europe. |
| D．Burning hot weather will appear in the United States. |
| A．researchers have analyzed the data collected in eleven years |
| B．long-term weather conditions can be accurately predicted depending on UV levels |
| C．the research doesn’t seem correct and true enough due to limited satellite data used |
| D．climate scientists have just begun their research in severe weather forecast |
Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to determine which experiences can influence healthy development in people.
Researchers at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people.
The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers.
Another study has suggested that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems.
American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987. At birth, each child weighed fewer than two thousand grams.
The boys and girls had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests in their homes. Their test results were compared with those of other children their age.
小题1:According to the passage, some people used to think that babies began to learn _________.
| A．on their first day of life | B．even before they were born |
| C．before five or six months old | D．at or after five or six months old |
| A．smiles | B．cries | C．facial expressions | D．body language |
| A．what affects people’s healthy development |
| B．what influences babies’ learning ability |
| C．how to cure some children’s health problems |
| D．how to develop children’s learning ability |
| A．The evaluation method of the tests. |
| B．The cause of low birth weight babies. |
| C．The result of the intelligence and motor skill tests. |
| D．The evidence proving babies began to learn before birth. |
With exams around the corner, how can you possibly pack in one more English word, let alone the causes of the Cold War? Don’t worry. Here is our handy guide to help you
Power Down
So you stayed up too late last night reading Mockingjay for the fifth time. Oops! When you’re that fired, your schoolwork suffers. Instead of studying inefficiently while you are sleepy, allow yourself a 15-minute afterschool power nap. Studies show that even a few minutes of shut-eye can improve memory and concentration.
Take Notes
Not quite grasping that super complicated concept in your chemistry class? You may need to change the way you take notes. Instead of recording every word your teacher says, try using visual hints like pictures, symbols and word bubbles. You can even switch computer fonts or pen color for the important stuff.
Dream On
Your bed’s not just for zzz’s. Experts say it may be good to study in bed, too. Why? We’re able to absorb more right before bed because we’re less distracted and the new information stays in our minds as we sleep. So, slide into bed with a textbook or notes, read for 15 minutes, and then turn off the lights for some sweet and smart dreams.
Brain Food
You’re in the middle of a biology exam when your mind goes blank. You knew this stuff cold at home, but now you can’t tell a ribosome from a chloroplast. What’s going on? Your brain’s in need of some refueling. Have some snacks like apple slices or cheese before class, and have plenty of water, too. If your teacher doesn’t mind, pop in a piece of gum during an exam. Some scientists think the chewing increases the flow of oxygen to the brain.
Smart Move
Ugh! You’re taking an English test and you cannot remember the past participle of “understand”. What to do? Skip it. Test taking is all about timing, so don’t waste it on tricky questions. Move ahead and answer everything you know before returning to the ones you don’t. Chances are, once you get back to the toughies, you’ll recall the answer or at the very least, you’ll have a little more time to come up with one that works.
小题1:When taking notes, we can do all these except ______.
| A．draw pictures | B．change the typeface | C．switch on the computer | D．colour the key points |
| A．it’s good to study under the covers for some time every day |
| B．you cannot skip the difficult questions and go on to the rest |
| C．you can have some snacks and drink enough water to refresh yourself in exams |
| D．when taking notes, you should record whatever the teacher says |
| A．had no clue about it | B．were a cold fish | C．knew it was cold | D．were familiar with |
| A．Power down | B．dream on | C．eat brain food | D．make a smart move |
