Believe it or not, oceans and seas are easy to be harmed by the development of human society. They are also influenced by man-made pollution easily. It is human beings that do great harm to the ocean ecosystems(生態(tài)系統(tǒng)).
The coral reefs(珊瑚礁)are fine ecosystems that provide food and protection for many ocean creatures. The coral in almost all of the oceans is in danger from pollution.Chemicals from factories end up in the seas and oceans and destroy coral reefs. If the coral systems die some ocean creatures will be sure to die out.
Protecting the ocean also has something to do with the protection of ocean wildlife like dolphins. The fishing industry depends on modern ways to catch many fish in order to earn more money. But the nets for fishing also seize other sea animals. The fishing boat workers are advised to check their nets and set other ocean animals free. But the boats are in a hurry to make money and often other ocean animals are caught with fish.
Offshore oil spills(近海石油泄露) can destroy the ocean environment because oil kills all ocean life. The world depends on oil and because there is a great amount of oil off the shore of many countries, the need for oil is more important than the risk of the oil spill. However, the fact is that one human mistake can lead to an ocean environmental accident that will cause years of damage to the fine ocean ecosystems. Oil spills will kill all the creatures in the area of the spill. The oil will be washed up on shore and destroy the ecosystems along the shore including birds.
Everyone who cares about the environment should be interested in protecting the ocean, and all of us should do something for the protection of the ocean.
小題1:According to the passage, the ocean is harmed easily as a result of      .
A．the overuse of the oceans
B．the change of natural conditions
C．the increase of population by the sea
D．the increasing activities of humans
小題2:What does the second paragraph mainly tell readers?
A．How ocean creatures depend on coral reefs.
B．Coral reefs are home to ocean animals.
C．The great harm caused by factory pollution.
D．The importance of protecting coral systems.
小題3:The underlined work “seize” in Paragraph 3 can be replaced with“      ”.
A．catchB．a(chǎn)ttractC．placeD．cover
小題4:Why do people continue to get oil in the sea at the risk of oil spills?
A．Because they believe the oil spill can be stopped.
B．Because there is a large amount of oil in the sea.
C．Because they are in great need of oil.
D．Because getting oil in sea is easier than on land.

There are only about 1,000 Hawaiian monk seals(夏威夷僧海豹) left and its population is going down 4% a year. Hawaiian monk seals are found in the northwest part of the Hawaiian Islands. They spend a lot of time at sea. They are able to dive 600 feet deep, and can stay under water for up to 20 minutes. Adults grow up to seven feet long, and weigh between 400 and 600 pounds. They can live as long as 30 years.
These seals are born on land. Every year, usually in May or June, females find sandy beaches and give birth to a single baby. The female seals avoid beaches where the water becomes deep very quickly because this lets sharks swim close to land and catch the seals.
Mothers stay with their babies for six weeks. During that entire time, they do not leave the beach even to eat. Instead, they live off fat that they have stored up over the previous year and feed their babies with fat-rich milk. After six weeks, mothers go back to the sea. The young have to live on their own.
Human disturbance(打擾) has been regarded as the important factor in the decrease of the monk seals. In fact, if human come too near a mother seal too often, she will go out to the sea. Unfortunately, this usually means death for the baby. It is now against the law for people to come within 100 yards of a seal on a beach.
Recent research has shown that the decrease in the Hawaiian monk seal population is due to lack of survival of these seals at one of the most important breeding(繁殖) beaches at French Frigate Shoals. Also, seals often get trapped in fishermen and by changes in weather patterns. If these threats(威脅) were not enough, during the breeding season, males will attack females until they are badly injured or finally killed.
小題1:What can we learn about Hawaiian monk seals?
A．They are in danger of dying out.
B．They spend most of the time on the beach.
C．They are the largest animals on the Hawaiian Islands.
D．They can stay under water as long as they like.
小題2:According to the text, a seal baby______.
A．is born at sea
B．is fed on fat by the mother
C．stays with its parents all life
D．is looked after by its mother for 6 weeks
小題3:It can be inferred from the text that______.
A．sharks are a threat to Hawaiian monk seals
B．male monk seals fight each other for females in the breeding season
C．when disturbed by people, the mother seal will protect the baby seal
D．Hawaiian monk seals give birth usually in July
小題4:What are the last two paragraphs mainly about?
A．Ways to protect Hawaiian monk seals。
B．The struggle of Hawaiian monk seals to survive.
C．The reasons for the decline(減少) of Hawaiian monk seals.
D．The influence of climate change on Hawaiian monk seals.

The office has always been a place to get ahead. Unfortunately, It is also a place where a lot of natural resources start to fall behind. Take a look around next time you’re at work. See how many lights are left on when people leave. See how much paper is being wasted. How much electricity is being used to run computers that are left on.

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing---paper. No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seems to run out of ink at the critical moment. A “paperless classroom” is what more and more schools are trying to achieve .
Students don’t do any handwriting in this class . Instead , they use palm size , or specially—designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer. Having computers also means that students use the Web. They can look up information on any subject they’re studying from maths to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said .“Using a book that’s three or four years old is impossible.”And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie—Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computers,”she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi—tech students.
小題1:What does the part of the last sentence in the first paragraph “run out of ink at the critical moment” mean ?
A．Pens may not write well at the critical moment.
B．Pens get lost easily , so you may not find them at the critical moment.
C．Pens may have little or no ink at the critical moment
D．Pens use ink, while pencils don’t.
小題2:The high school teacher, Judy Herrell, used the example of her class to show that ________.
A．the Web could take them everywhere
B．the Web taught them a lot.
C．the Web is a good tool for information.
D．the Web , better than the textbooks ,can give the latest and comprehensive information.
小題3:The paperless classroom will benefit _________ the most.
A．studentsB．teachersC．treesD．computers
小題4:What does the phrase in the last paragraph “break down ”mean ?
A．Break into piecesB．Stop workingC．Fall downD．Lose control

In most parts of the world, many students help their school make less pollution. They join in “environment(環(huán)境) clubs”. In an environment club, people work together to make our environment clean.
Here are the things students often do.
Turn off the water! Do you know that some toilets can waste twenty to forty tons of water an hour? In a year, that would fill a small river! In environment clubs, students mend those broken toilets.
No-car day. On a no-car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember:
Walk, jump, bike or run.
Use your legs! It’s lots of fun!
No-garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
We love our environment. Let’s work together to make it clean!
小題1:After mending the broken toilets, they save ________.
A．a(chǎn) small riverB．a(chǎn) lot of waterC．a(chǎn) toiletD．a(chǎn) year

Making friends is a skill like most skills. It improves with practice. If you want to meet people and make friends, you must be willing to take some action. You must first go where there are people. You won’t make friends staying home alone.
Joining a club or a group, talking with those who like the same things as you do is much easier. Or join someone in some activity.
Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it’s human nature to feel a bit uncomfortable about unknown. Most of our fears about dealing with new people comes from doubts about ourselves. We imagine other people are judging us, finding us too tall or too short, too this or too that. But don’t forget that they must be feeling the same way. Try to accept yourself as you are, and try to put the other person at ease. You’ll both feel more comfortable.
Try to act self-confident even if you don’t feel that way. When you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile.
If you see someone you’d like to speak to, say something. Don’t wait for the other person to start a conversation.
Just meeting someone new does not mean that you will make friends with that person—friendship is based on mutual liking and “give and take”. It takes time and effort to develop.
小題1:The best topic of the passage may be ________.
A．FriendshipB．Making friendsC．Meeting New PeopleD．Facing the Unknown
小題2:Which of the following statements is NOT TRUE?
A．Making friends needs practicing.
B．Making friends needs to be more active in getting in touch with people.
C．When meeting someone, make him feel nice and easy.
D．Before making friends with someone, judge him if he’s too this or too that.
小題3:The development of friendship needs ________.
A．a(chǎn) lot of moneyB．lots of conversation
C．time and effortD．carefully judging
