六、语法填空
根据短文内容，在空白处填入一个适当的单词或括号内单词的正确形式。
Do you know what the world’s tallest animals are How do they sleep and drink
You may think it's difficult for them 1 ( sleep), but they have no such problems because giraffes don't often stop for a snooze(打盹). As they are so tall—males can grow up 2 8 meters, giraffes actually have 3 (short) sleep requirement of all mammals, with an average (平均) of half an hour a day. When they sleep, they seldom lie down and sleep for minutes at a time, since it's difficult for them 4 (get) up again and it's 5 ( danger) in the wild. But the giraffe in the zoo sleeps around 4-6 hours per day, mostly at night. It usually sleeps 6 (lie) down.
7 (drink) water may cause problems for the animals because their long necks are too short to reach the ground. 8 (drink) they must spread their legs in an 9 (comfortable) position, which makes them easily hunted by other animals like Africa's big cats. As a result, they get most of their water 10 the plants that they eat. They only need to drink water every few days.
七、阅读表达
Huge Waves Destroying Arctic Ice
Faster than Expected
　　Ice covers much of the Arctic Ocean. Some pieces of ice are huge, like moving islands. As temperatures have increased, however, some of the ice has begun to disappear. Scientists have discovered huge waves in the arctic waters.
　　The waves were discovered by accident in May, 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.
　　The ship traveled east and stopped next to a large block of ice around 50 miles from the small island of Hopen. Marchenko prepared to lead his students out onto the ice.
“We were ready to go but when I went out, I discovered many cracks around,” he remembers.
　　He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces,
　　Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship's navigation system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists had never imagined that the process could happen so fast. The waves in these areas used to be small.
　　The speed and force of the huge waves there makes it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them. Wildlife like polar bears that depend on sea ice to live is also in danger.
　　Some scientists think people will soon see even bigger waves in icy waters. As waves break up ice, seas will be more open, and waves will be stronger. There are stormy times ahead.
