【题目】阅读理解。

A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing…right?Perhaps,but some developmental psychologists have argued that this “play” is more like a scientific investigation than one might think.

Take a closer look at the baby playing at the table. Each time the bowl of rice is pushed over the table edge, it

falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby’s investigation and the scientist’s experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?).

Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has. for example, unlike the child , Mommy actually doesn’t like Dove chocolate.

Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, ”It is not that children are little scientists but that scientists are big children.”

【题目】（河南省焦作市2016届高三第一次模拟）阅读理解。

The editor of the new Cool Camping Britain guide chooses some of his favorite new finds in England, Wales and Scotland.

Cleadale, Isle of Eigg, Inner Hebrides

Is this Britain’s most beautiful campsite? From the grassy point looking seaward to the mountains, it’s not hard for campers to see how the island inspired The Lord of the Rings author’s fantasy landscapes. The campsite itself is as wild and wonderful as its setting.

Open April — September, from ￡5 per tent per night.

Swattesfield, Thornham Magna, Suffolk

Deep in the wilds of north Suffolk, this seven-acre campsite has only been open for a few years, with two fields separated by a lake and surrounded by woodland. The position is perfect. It’s a great place to do nothing but get into nature. You can put up your tent in the bottom field or the woodland beyond.

Open Easter — October, from ￡10 per tent per night.

Pleasant Streams Farm, near St Austell, Cornwall

This site, by a lake, is all about simple pleasures. Located in the former mining village, it has a summerhouse（凉亭）with books and games for a rainy day. There are many animals including pigs, hens, goats and ducks on the farm and a pub just a 10- minute stroll away. There’s very little to do here, no bells and no whistles. Campfires are encouraged.

Open Easter — September, from ￡10 per tent per night.

Troytown Campsite, St Agnes, Isles of Sciily

Its only campsite, Troytown, couldn’t be in a more remote position. Isolation is its greatest advantage — so bring plenty of books to read and don’t expect a phone signal. But at least one of life’s necessities is available. Lying on the hillside overlooking the bay and near the island of the Gugh, it might just win the prize for best beer garden view in England.

Open March October, from ￡7. 50 per tent per night,

【1】Which of the following is TRUE about Cleadale, Isle of Eigg, Inner Hebrides?

A. It has been open for a few years.

B. A beautiful lake surrounds it.

C. It offers the longest service.

D. The rent of a tent per night is the lowest.

【2】Which place can you choose if you like a simple farm life?

A. Cleadale, Isle of Eigg, Inner Hebrides.

B. Swattesfield, Thornham Magna, Suffolk.

C. Pleasant Streams Farm, near St Austell, Cornwall.

D. Troytown Campsite, St Agnes, Isles of Scilly.

【3】In Troytown Campsite, St Agnes, Isles of Scilly, you can’t ________.

A. contact others by phones

B. view the bay from the hillside

C. get everyday necessities

D. relax yourself by reading
