1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

As you have noticed, you and a fish are different. Eyelids (眼睑), for example. Even sleep is a difference between you     1     a fish.

As far as scientists can tell, even though it’s hard     2    (study) the brains of fish, fish do sleep in     3     way. They at least rest at times, with a slowdown of their body “machinery”. And that is much like sleep.

For fish brains to relax, eyelids may not     4    (need). Some fish lie near the bottom or top of the sea or lake at night. Others hide     5    (them) in the sand or produce a covering as     6    (protect) against predators (捕食者) while their defense (防御者) are sleeping. And sharks—even the kinds     7     continually swim—still have periods of rest in between periods of activity.

Fish don’t have eyelids or need them. Eyelids help us     8    (human) by keeping our eyes from     9    (get) dry, among other things. But dry eyes are     10    (probable) not a problem for animals living in water.

2 . Nola （August 21, 1974 -November 22, 2015） was a northern white rhino who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 22, is to raise awareness（意识）of the less than 30,000 other rhinos left on Earth.

“Rhinos need our help today, not tomorrow. "Nola's lead keeper Jane Kennedy said. "Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the earth will be gone."

Unfortunately, most animals are in danger of dying out because of humans. Kennedy says, “Humans have either poached （偷猎）animals, or because there are over seven billion of us, we've taken up too much of the world's resources." Poachers illegally hunt rhinos for their horns （角）.They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples（细胞样品）from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. For more information, go to www.worldrhinoday.org.

3 . On a farm in England, Gavin and Alice Munro are taking sustainability to the next level: they harvest trees which they grow into chairs.

The couple have a furniture（家具）farm in Derbyshire where they are growing 250 chairs, 100 lamps and 550 tables. It is their answer to what they see as the inefficient（无效率的）process of cutting down mature trees to create furniture.

"Instead of force-growing a tree for 50 years and then cutting it down and making it into smaller and smaller bits…the idea is to grow the tree into the shape that you want directly. It’s like a kind of 3D printing, "said Gavin.

Part of the inspiration for the idea came when Gavin was a young boy. He spotted an overgrown bonsai tree（盆栽） which looked like chair.

The 44-year-old began experimenting in 2006. In 2012, Gavin and Alice set up the company Full Grown. Within several years, the couple developed the most effective way to shape a tree without limiting its growth. They guided shoots（嫩枝）already heading in the right direction, rather than force them the wrong way against their natural growth.

The average chair takes six to nine years to grow-and another year to dry out. The labor and time involved in producing the organic pieces means they do not come cheap. Chairs sell for ￡10,000 each, lamps for ￡900 to ￡2,300 and tables for ￡2,500 to ￡12,500.

1. How could the couple grow trees into a shape they needed?

A．They used 3D printing.

B．They limited their growth.

C．They forced trees into different shapes.

D．They guided their shoots in the right direction.

2. When did Gavin get the idea of growing furniture?

A．When he was a child.	B．When they got married.
C．When they bought the farm.	D．When they began experimenting in 2006.

3. Which can best describe the furniture?

A．Big and eco-friendly.	B．Natural but expensive.
C．Hand-made and creative.	D．Traditional but organic.

4. Which of the following can be the best title of the passage?

A．A Couple Grow Furniture	B．Expensive Grown Chairs
C．It’s A Good Try Of Sustainability	D．Grown Trees Gain Popularity
