They killed the birds on the island 4 the environment of the island was not built to save its birds from the rats.

In 2007, the U.S. Fish and Wildlife Service started a(n) 7 to make the rats stay away from the island and try to bring back the beautiful birds.

Hi! My name is Nicholas. I am 12 years old. I am from Liverpool and I live there with my parents and my siblings — Sean, who is 10 years old, and Diana, who’s 4.
Our day starts at 7 o’clock. Everybody gets up and gets ready to leave home at 7:45. I usually take a shower in the evening, so I just have to wash my face, brush my teeth, and put on my school uniform. We all have breakfast at 7:30.
After breakfast, Sean and I catch the bus to school. Classes begin at 8 o’clock.
Mom and Dad drive to work after leaving Diana at the kindergarten (幼儿园). My dad is a doctor and my mom is a nurse. They both work at the local hospital.
When school finishes at 3 o’clock, Sean and I take the bus home. We have a glass of milk and some bread and then we do our homework. On Wednesdays we go home late. Sean goes to the Internet Club and I go to the Music Club. I want to be a famous musician. That’s why at the weekend I go to L.I.P.A. — the Liverpool Institute for Performing Arts. It is one of the best performing art schools in Britain. I have drama, singing and dancing lessons.8
I’ve always loved music and I started playing the piano when I was 4 years old. I’ve also learned to play the drums and the guitar. When I grow up, I want to take a music degree (学位) at L.I.P.A. I must study hard to get high grades because they only have 35 places available each year. One of those places has to be for me! 根据材料内容选择最佳答案。

Were dinosaurs (恐龙) warm-blooded or cold-blooded? According to a new study, scientists have found that they were somewhere in the middle. This new study shows that dinosaurs were very different from most of today’s animals that are either warm or cold-blooded.6
“I think we were all surprised by this,” said Felisa Smith from the University of New Mexico. “The idea certainly took some getting used to.”
The last dinosaurs lived on the earth more than 60 million years ago. However, there is always more to discover about these ancient animals. 【0：21·3·7·网】
A study by a team of scientists led by John M. Grady of the university studied many different kinds of dinosaurs in their research. They looked at growth rate (比率), body temperature and body size of different kinds of dinosaurs.
How are warm-blooded animals different from cold-blooded animals? Warm-blooded animals like humans can control their body temperature. They eat a lot, and burn calories (卡路里) quickly. They have a more active lifestyle than cold-blooded animals. While cold-blooded animals such as snakes do not control their body temperature. Instead, they must use sunlight to keep warm, and they move much more slowly. Cold-blooded animals do not need to eat very much. Their bodies slow down in colder temperatures.
Dinosaurs were in the middle because they didn’t completely control their body temperature, but their body temperature didn’t only depend on the environment either. This helped dinosaurs and allowed them to live for so many years.
Besides dinosaurs, there are other animals that are not completely warm-blooded or cold-blooded, such as great white sharks. 根据材料内容选择最佳答案。
( )6. According to the new study, ______.
A. dinosaurs were cold-blooded B. dinosaurs were warm-blooded
C. dinosaurs were not completely warm-blooded or cold-blooded
