Tired of all the pushing in supermarkets? Fed up with waiting in endless lines to pay for what you have bought? Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store? If this is you, then online shopping is the answer to your dreams of trouble-free shopping. Online shopping brings its own challenges. Here are a few things to bear in mind whenbrowsing various websites. Theclaim made by online sites is that shopping online is a safe and secure way to make purchases. The evidence challenges this. In any case, you only have to be thevictim offraud once to experience all the problems that come with this form of stealing. Use only sites that have a trusted history and an excellent reputation . Another problem is that the appearance of items in reality is often quite different from what you see on your computer screen. This might not be a problem if you are buying washing up powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green. Also, product descriptions are sometimes simply untrue! Perhaps the wisest plan is to purchase items whose design and color are not essential to customer satisfaction. Some even argue that online shopping indirectly contributes to global warming. Yes, your car can stay parked but how are online goods delivered? Often by some large van pouring out carbon monoxide and adding to our already desperate traffic problems. You are also by now becoming increasinglyirritated by the fact that the delivery is late ! Without question, online shopping is here to stay and it has its benefits. However, perhaps it is not as wonderful as some of its supporters claim it to be. How can online shoppers avoid fraud? A) By choosing big websites. B) By collecting shopping evidence. C) By seeking advice from the police. D) By using only trusted websites.

It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study. The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain. And they came across astounding results. It was found that infants had "social brains" and focused not just on their mothers but on social life in groups as well. "They communicate with more than one baby at once, and show jealousy and generousness," said Professor Bradley. He added, "They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers." "A baby who has a depressed mother tends to be withdrawn ( ), but put that same baby in a group of its peers and they behave and interact like any other baby." It was the first all-baby group study ever to be conducted. "Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach," said Bradley. Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney's inner west, said she often noticed what appeared to be emotional attachments developed between toddlers. She said, "Joel ( 10 months ) and Isabella ( 11 months ) always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing." A baby who has a depressed mother _ . A) tends to be a follower B) also enjoys group interaction C) has poor social ability D) pays more attention to its mother

Q: iPhone 6, which many people have been thirsty for, will be unveiled on September 9. It could go on sale to the public from Friday, September 19. Apple has launched a new iPhone every year since it unveiled the range in 2007, selling more than 500 million units since then, and has traditionally launched key products in September. The iPhone 6, Apple's ninth iPhone model, is expected to be released in two different sizes:4.7-inches and 5.5-inches. The smaller of the two will be available first. Like iPhone5, the new model will come in silver , gold and space grey. The iPhone 6 will be powered by new operating system iOS 8. Through iOS8, users will be able to monitor their health and fitness via HealthKit. HealthKit puts together numerous healthcare and fitness apps, such as blood pressure and heart rate monitors through partners including Nike, and allows them to communicate with each other. Users will be able to control home appliances and other connected devices through HomeKit, Apple's connected home framework. Similar to HealthKit, this app will organize your smart devices to control them in one place. One method of control will be via Siri-for example, you could tell Siri you were "going to bed", and it could dim the lights, lock your doors, close the garage door and set the room temperature. With the introduction of both of these key features, it's likely the iPhone 6 will take on even more of a lifestyle device role. It is designed to organize our lives and make everyday tasks easier and more efficiently completed. Suppliers are believed to be preparing to produce up to 80m of the new handsets by the end of December, according to the Wall Street Journal. In July, Apple announced strong financial results for its third quarter, with significant sales growth in China and profits ahead of expectations at $7.7bn. What is mainly talked about in the passage? A) iPhone 6 will make more money than ever. B) iPhone 6 has the most advanced technology. C) iPhone 6 will enjoy great popularity around the world. D) iPhone 6's new features will make people's life easier.
