How did the sea horse get its name? It's not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse's tail, you might think "sea monkey" is a better name. Then there's the sea horse's pouch(口袋). "Sea kangaroo" might also be a good name for this fish.
Sea horse live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings(环境). A sea horse in one place for hours at a time by winding its tail around a plant. It feeds on live food, such as small shrimp(虾). For a fish that doesn't move around much, the sea horse eats a lot-- in just one day, a sea horse can eat 3,000 shrimp!
A sea horse keeps the same mate for its whole life, and it's the male(雄性的) sea horse that gives birth to baby sea horses. How does this happen? Baby sea horse start out as eggs, which come from the female's(雌性的) body. The male carries the eggs in its pouch for about three weeks until they hatch(孵化). Soon after the babies are born, the female gives her mate a new set of eggs.
Sadly, the number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and sold as aquarium(水族馆) fish. This really is not a good idea because most sea horses don't live long in aquarium. The best place for a sea horse is the ocean.

Last year I 【小题1】 (work) in Nepal for three months. When I had a few days off，I decided 【小题2】 (go) into the jungle (丛林) . I asked a Nepalese guide，Kamal Rai to go with me.

We started our trip at six in the morning with two elephants 【小题3】 (carry) our things. It was hot, but Kamal made me wear shoes and trousers to protect me 【小题4】 snakes. In the jungle there was a lot of wildlife, but we were trying to find tigers. We climbed onto the elephants' backs to see better. However, 【小题5】 is unusual to find tigers in the afternoon because they sleep in the daytime.

Then, in the 【小题6】 (distant), we saw a tiger, and Kamal told me to be very quiet. We moved nearer and found a dead deer, 【小题7】 was the tiger's lunch! Suddenly, I started to feel very 【小题8】 (frighten), then a huge tiger jumped out suddenly. It caught Kamal's leg between its teeth, but I managed to pull Kamal away. One of our 【小题9】 (elephant) ran at the tiger and made it go back into the grass, so we 【小题10】 (quick) ran away.  That night it was impossible to sleep!

   Many years ago in a zoo，I was shocked by finding that chimpanzees could behave in a more civil manner than youths. Great apes（类人猿）are always one of the favourite attractions in any zoo. The main reason for this is that they are so similar to us.

This similarity has persuaded a group called the Great Ape Project（GAP）to campaign for these animals to be afforded“human rights”.

This has resulted in laws in New Zealand，which could mean that great apes would become the first animals in the world with basic rights protected by the law.

Not everybody is happy with this idea，however. Scientists using animals for scientific research fear that this is just the first stage in a process that will lead to a ban on using all animals for research.

The GAP declaration claims great apes should have“human rights”due to scientific evidence about their abilities. But if we compare the abilities of humans and great apes，then why not the abilities of great apes and monkeys，monkeys and lemurs，and so on until insects are granted“human rights”？This is not foolish. There are people without basic human rights. How long ago，for example，did women not have the right to vote？

Yet another argument by those who don't support GAP is that the human-like qualities of great apes have been exaggerated（夸大）for certain reasons，and that this has led people to exaggerate the similarities but ignore the differences between humans and great apes.

In a fascinating book entitled What It Means to be 98% Chimpanzee，Jonathan M. Marks points out that，although a human and a daffodil（水仙花）share the common ancestry and their DNA matches more than 25% of the time，it is plainly ridiculous to claim that we are one-quarter daffodils.

He goes on to demonstrate that，if looked at from one angle，it is true that we are apes phylogenetically. But also fish from another angle！“It doesn't sound quite so profound now，does it？”

【小题1】What does Paragraph 1 mainly talk about？

A．The experience was unforgettable.

B．Chimpanzees are similar to humans.

C．Chimpanzees are very popular in the zoo.

D．Animals could behave better than humans.

【小题2】Which of the following would the Great Ape Project most probably agree with?

A．Animals should be free from any scientific research.

B．New Zealand should do more to protect the rights of great apes.

C．The differences between humans and great apes have been ignored.

D．Great apes have adequate characteristics to be included as our equals.

【小题3】How does the author develop his idea mainly in Paragraph 5?

A．By reasoning.

B．By giving examples.

C．By making comparisons.

D．By providing scientific evidence.

【小题4】What point does Jonathan M. Marks try to make in his book?

A．Humans are more than one-quarter daffodils.

B．Great apes and fish are phylogenetically similar from another angle.

C．Humans are as similar to fish as they are to great apes.

D．Being 98% genetically identical matters less than thought.

   Penguins are the number-one attraction for many visitors to Antarctica. If you go on a ship that is allowed to make shore landings, you may see them. But to get a close look at penguins, you have to be smart.

First of all, keep in mind that Antarctica’s visitor rules require that you remain at least five meters away from the penguins in order not to disturb them. You could easily become responsible for the death of a little penguin or the destruction of an egg if your too-close presence should disturb a penguin parent.

If a penguin is trying to move away from you, you must stop what you’re doing and back off even if you’re farther than five meters away. However, the rules don’t prevent a curious penguin from approaching within five meters of you — as long as the bird makes the move, not you.

Little penguins, in particular, are quite curious. I’ve seen several lucky tourists who were astonished to find that little penguins came right up to them. If a penguin comes extremely close to you, remember that you are not allowed to touch or hold it.

Here are more tips for getting close to penguins.

Ignore the smell: where penguins live is filled with guano（海鸟粪）and the smell takes some getting used to.

Be quiet because loud noises make penguins nervous. Fast or sudden movements signal meat — eating animals to penguins, and they react accordingly, so slow down when you walk around them.

Since it may take half an hour or more before the penguins get used to you, you need to be patient. Put away your camera — too often people are so focused on getting the pictures that they forget to look with their own eyes, but most of your most memorable experiences in Antarctica will be marked in your mind, not on a roll of films.

【小题1】What will happen if visitors disturb penguins according to Paragraph 2?

A．Visitors may step on a little penguin.

B．Penguin parents may break their eggs.

C．Visitors are easily attacked by penguins.

D．Penguin parents may attack other animals.

【小题2】When a penguin is trying to move away from you, you’d better ____________.

A．step back	B．try to stop it
C．go after it quietly	D．keep five meters away from it

【小题3】If a penguin comes very close to you, ____________.

A．you may hold it

B．you may touch it gently

C．you should stay where you are

D．you should walk away carefully

【小题4】The author advises visitors to Antarctica to ____________.

A．ignore loud strange noises

B．take as many pictures as they can

C．allow penguins to get used to them

D．stay away from meat-eating animals

   According to a study published last week in the journal Science，scientists have found a way to change a plant's genes（基因）in order to make it use sunlight more quickly. Someday，the results could increase the amount of food produced around the world.

By changing a plant's genes，the scientists were able to increase leaf growth on plants by 14-20 percent. Specifically，scientists changed the plant's protective（保护的）system. “Normally，this system is activated when a plant gets too much sunlight，”said scientist Krishna Niyogi，co-author of the study. “When the plant senses the light，it gets rid of extra energy and creates more leaves. When the plant is in the shade，the protective system is turned off. But the process is slow.”

Stephen Long is the lead author of the study. He compared a plant's protective system to light-adjusting glasses.“When a person wears the glasses outside during the day，the lenses（镜片）darken and lighten depending on how sunny it is. Plants do the same thing，”he said.“But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food.”

The new study sped up the process. By changing the plant's genes，it's more quickly than normal to turn on and turn off the protective system. As a result，leaf growth on the plants scientists used in the study increased. Leaf growth on two plants increased by 20 percent, while leaf growth on a third plant increased by 14percent. Scientists conducted the study on tobacco plants. But they thought the genetic modification would produce the same results in corn or rice.

【小题1】What does the plant's protective system need to keep activated?

A．Mild shade.	B．Leaf growth.
C．Genetic changes.	D．Enough sunlight.

【小题2】What does the underlined word“modification”in Paragraph 4mean?

A．Development.	B．Decoration.
C．Change.	D．Copying.

【小题3】What can we infer from this text?

A．Changing how a plant uses sunlight could mean more food in the future.

B．When the plant is in the shade, its protective system is turned off slowly.

C．Too much sunlight will damage plants' protective system.

D．It is hard for plants to create food without enough sunlight.
