Popular wisdom has it that parents' relationships may suffer once their young fly the coop, because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley, has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together. In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies, once their children reached their teenage years and finally at age 61, when almost all had "empty nests". Although not all said they were happier in general, most claimed their marriages had improved since their children had left home. Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other's company more. One of the participants in the study,which is published in the journal Psychological Science,said:"Once the kids grow up...there's some of that stress removed...that responsibility removed,so things are a little more relaxed." Psychologist Sara Gorchoff,who carried out the investigation,said: "The takehome message for couples with young children is 'hang in there'." Her coauthor Oliver John added:"Don't wait until your kids leave home to schedule quality time with your partner." However, Dr Dorothy Rowe,from the British Psychological Society,said the effects of living in an "empty nest" will depend on the parents' relationship with their children."If you're just waiting for them to leave home so you can get on with your life,then of course you'll be pleased to see them go," she said, "But if you've built your life around your children you'll be terribly lonely.For some parents,their world falls apart when their children leave." Question: It is commonly believed that _ . Options: A: marriages improve after children leave home B: an "empty nest" is always a happy thing C: parents' relationships may suffer once their young grow up and move out D: parents will be pleased after their children leave home

Read the article and select the best answer. Article: Dogs are known for a strong sense of smell. Their noses can be trained to identify different smells. Dogs are often used in search and rescue operations and to sniff for things like drugs and explosives. Some dogs have even been trained to sniff for cancer in people. Researchers have been trying to reproduce the extraordinary sense of smell that real dogs are born with. Now, officials at the Glasgow airport in Scotland are testing a new security device called an "electronic sniffer dog". The electronic sniffer dog represents one of the latest developments in the area of smell technology. A Scottish company, Cascade Technologies, joined with the French security company Morpho to develop it. The device uses lasers to identify explosive materials in gases in the air. The purpose is to identify explosives that may be hidden on a person's body. The machine looks similar to the metal detectors now used at airports. Passengers walk through the machine as the lasers test the surrounding air. People are not required to take off their coats, belts or shoes as part of the security process. And, unlike full-body scanners, the new device does not show images of the passengers. Officials at Cascade Technologies say the machine can process one person per second and produce almost immediate results. They say future development could cut security processing times at airports by screening all passengers at walking speed. Professor Yushan Yan, the head of Chemical and Environmental Engineering at the University of California, Riverside, points out that unlike real dogs, electronic devices do not get tired or need to be walked or require food and water. Professor Yan says real dogs also have other needs. "They also need very extensive training that could be expensive. And when they work they have to have a very skilled handler around them." But Professor Yan says there is an important area where man's best friend still wins compared to technology. "In terms of sensitivity and selectivity, the current technology out there is... Question: The electronic sniffer dogs will be used to _ Options: A: replace real dogs to be as pets for people B: search for and rescue people who are in trouble C: help people look after patients in the hospital D: identify drugs and explosives in places like the airport

Read the article and select the best answer. Article: Roman Pantheon is one of the greatest achievements of the ancient Romans. The ancient Romans were good architects and they built many wonderful buildings. Another good example of a Roman architectural style is the Roman Coliseum, which is a large building used for public sports events or entertainment. The Roman architectural style has been borrowed by many of the western countries. The architecture of Pantheon is unique to Rome. In Latin and Greek, pantheon means "Temple of all the Gods". Marcus Agrippa built the original Pantheon in 27 BC. But the Pantheon built by Agrippa was completely destroyed in 80 AD when a fire broke out. The Roman Pantheon that is visited by many tourists today was rebuilt in 125 AD by the Roman emperor Hadrian. Hadrian's architects followed the exact design of Marcus Agrippa. Historians believe that the Pantheon was a place of worship because it housed all the gods and goddesses of the ancient Romans. The Pantheon of Rome is an amazing example of ancient Roman architecture. This building has been in use for over 2000 years. The Roman Pantheon is famous for its design, size. The most unbelievable feature of this building is its huge concrete dome . The Pantheon's dome was thought to be the largest, until recent times. Phocas, the Byzantine Emperor presented the Roman Pantheon to Pope Boniface IV to save it from the destruction. In 609 AD, it was turned into a church. During Papal rule, it was used as a burial ground for kings and other famous people. There are tombs of Raphael (a painter), King Victor Emmanuel II, King Umberto I and many more in the Pantheon. Some of the buildings that were constructed on the model of the Roman Pantheon are The Rotunda - University of Virginia, Low Memorial Library - Columbia University, Grand Auditorium - Tsinghua University, Jefferson Memorial - Washington D.C. and Duomo - Florence.
