Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called “Internet of things”.
The Internet of things may be coming sooner than you think. Earlier this year, A Samsung CEO spent a lot of time talking about the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it’s a remote control or a washing machine.
So, how do household(家用的) objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.
An Internet-connected camera could help people feel safer in their homes. It can know people’s faces and has an infrared sensor(红外传感器),so even if it’s dark it can see when someone passes by and send you a message on your smartphone to let you know who’s there. If the person is someone you don’t know,it can tell you that ,too.
But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don’t have much built-in security, which means they could be hacked(被黑客攻击). Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014.
So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? I t may happen sooner than you think.

According to a recent newspaper article, girls do better than boys at every level of education．So it is hardly surprising that boys are now far more likely（可能的） than girls to go to universities.
“Eclipsed” (黯然失色)
Mary Curnock Cook, a leader of the University, is so worried about the future of boys that she wants to see a national effort to solve the problem．If this difference goes on growing, girls born this year will be 75% more likely to go to university than boys．
So what is at the root of this gap（差距）? Are there changes in the nature of universities which have led to the dominance of girls on campus? Are girls simply better at schoolwork these days, and boys less interested?
By the time teenagers get to their high school, the number of girls is bigger．So before they sit a single exam, there are probably more girls than boys who are likely to go to university.
“Waste of time?”
The average grade for a girl is C+ compared to C for a boy at A-level examinations．But the differences between boys and girls start much earlier on.
According to a University of Bristol study, boys are nearly twice as likely as girls to have fallen behind by the time they start school．Primary schools often have more female teachers, and mothers helping out.
According to the study, girls and boys often have different attitudes towards schoolwork．The report says : “Boys are more likely than girls to regard school as a waste of time.” What’s more, boys tend（倾向） to spend over one hour less per week on homework than girls．They are more likely to play computer games and less likely to read outside of school.
“There are a lot of boys thinking they can get away with the least work and wanting to spend their time doing other ‘more interesting things’,” says Roger Leighton, the former head teacher of Sydney Russell School．“Girls, on the other hand, tend to understand the need to work hard earlier on --- they take a longer view.”

Plants are very important living things．Life could not go on if there were no plants．This is because plants can make food from air, water and sunlight．Animals and men can’t make food from air, water and sunlight．Animals get their food by eating plants and other animals．Therefore, animals and men need plants in order to live．This is the reason why we find so many plants around us.
If you look carefully at the plants around you, you will find that there are many kinds of plants．Some plants are large while others are small．Most plants are green.
Some plants have many small leaves．Others have only a few．There are many kinds of leaves．Leaves are of different shapes and colors.

Vitamin C is needed for strong bones and teeth, and for healthy blood vessels (血管)．It also helps wounds to heal (愈合) quickly．The body stores little vitamin C, so we must get it in foods like oranges, and cabbage． |
