Question: Read the following article and answer the question. Article: Birds in cities are damaging their health by trying to sing above the noise of urban life. New research shows that male birds are trying to compete against traffic and city sounds.They are now singing louder and at higher frequencies,which could harm their vocal cords .Some birds are choosing to sing at night instead of during the day.This makes them more open to attack and also creates stress and exhaustion. "The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate.This could lead to inbreeding and a weak gene poo1."said Dr Sue Anne Zollinger of the.University of St Andrews. According to Zollingar,a bird group with a small gene pool might adapt less quickly to new diseases and could be wiped out. A study of the dawn chorus found that birds in Berlin sang up to 14 decibels louder than those in the forest.The birds sang loudest on weekday mornings. "By trying to sing over the sound of the city,birds ale rising vocal injury,"said Zollinger."All this puts the same strain on a bird's vocal cords as when a human need to shout to be heard--except that the birds are doing it all day,every day,"she said. "Singing under such pressure means birds have less control over the sound they produce.Their songs may lose quality and become more rough--sounding."said Zollinger.This could make them appear less attractive to female birds. Mark Constantine,author of The Sound Approach to Birding,said:"Birdsong is important for our quality of life and has been proved to reduce our blood pressure.When we live in the centre of large,urban areas,we get stressed and it's extremely good to have birdsong around us.The impact on humans of birdsong is massive.It harms us,as well as the birds,if their songs become louder and simpler. Question: According to Dr Sue Anne Zollinger,birds singing louder might eventually lead to _ . Answer:
OPTIONS:
- the harm done to man's health
- the dying out of a species
- the serious damage to the bird's vocal cords
- the decrease of the birth rate of a bird group
Answer: the dying out of a species

Q: Read the following article and answer the question. Article: In some countries,open campus is widely accepted. For example, French students have a two-hour lunch break from 11:30 a.m. to 1:30 p.m. During their lunch break, they can eat at home or at a restaurant. But students in the Philippines have a tougher schedule. They have only two 15-minute breaks and an hour for lunch. What Schedule would be best for American schools? Having breaks between classes is great, but having breaks off campus is even better. There are several advantages to open campus, including simple conveniences such as being able to eat different meals during lunchtime, rather than having the cafeteria dishes, as well as having the chance to take a break at home. However, there are more reasons I disagree with allowing high school students the right to have an open campus. Sure, it's great being able to escape school during the day for a while, but soon enough that may easily become the rest of the day. If open campus is allowed, it is very possible that such freedom will make it all too easy for students to skip their afternoon classes. Of course, there will be students responsible enough to come back to school. But unexpected problems such as heavy traffic, city bus delays or cars breaking down may prevent them from returning to school. It benefits the students to stay in school during lunch hours to avoid transportation issues. Depending on how close the school is to restaurants and students' homes, open campus could be a great idea. Unfortunately, though, most public schools in America are not located close enough to restaurants or students' homes, thus causing the negative results to outweigh the positives in the end. Question: In the author's opinion, open campus will probably _ . Answer:

OPTIONS:
- lead to heavy traffic
- cause students to cut school
- attract more students to school
- increase students' sense of responsibility

A: cause students to cut school

Q: Read the following article and answer the question. Article: Have you ever listened to young children talking in the playground? They are always boasting. They say things like, "My Dad's car is bigger than your Dad's," and "My Mom is smarter than yours." They particularly like to boast about their families. There were three little boys, Harry, Ted and Gavin, who were always boasting. Gavin was the worst. Everything about his family was always the best or the biggest or the most expensive. Whatever the others said, he could always go on better. One day when they were walking to school, Harry said, "My father had a bath twice a week," Ted spoke next. "That's nothing," he said. "Having a bath twice a week is dirty. My father has a bath every day, sometimes twice a day." Ted looked at Gavin. Now it was his turn. But what could he say? "This time," Ted thought, "I'm going to win." Gavin didn't know what to say. He couldn't say that his father had a bath three times a day. That was silly. He walked on in silence. Ted smiled at Harry, and Harry smiled back. They were sure that for once they had beaten Gavin. They reached the school gates. Still Gavin said nothing. "We've won," Ted said to Harry, but he spoke too soon. On the way home, Gavin said, "My Dad is so clean that he doesn't have to bathe at all."
