Have you ever cleaned and organized your increasingly high-tech households, your hard drive, phone or tablet? It's not just stuff. Your privacy needs a cleanup too. {#blank#}1{#/blank#}

    ⒈Clean up your browsers（浏览器）

    Cookies are blocking everything up and keeping your computer from running fluidly. A free program called CCleaner helps you sort out the cookies and archives（存档）you don't really need. {#blank#}2{#/blank#}. Cleaner analyses its backlog of information and lists the data that seems unnecessary.

    ⒉Speed up your smartphone

    Most of us already know about e desktops, but what about smartphones? Our phones are essentially handheld computers, and when they overflow with useless information, their operations can also slow down. These aren't necessarily apps, but overburdened call logs, search history, and saved texts.

    For Android users, there's 1Tap Cleaner, an app that earns its name. {#blank#}3{#/blank#} Most of us are surprised by how many updated messages and URLs get archived, a data stream that we will probably never refer to again. Then again, you do want to make sure irreplaceable bits (landmark texts, unsaved photos) survive the deep clean.

    ⒊{#blank#}4{#/blank#}

    Digital photos are easy to shoot, upload and copy, which is handy in almost every respect, especially if you grew up lugging rolls of film to the one-hour photo lab. The downside is that you may end up with multiple copies of the same picture. If you're shooting with a decent camera, each shot could take 10MG or more of space. This volume adds up.

    {#blank#}5{#/blank#} This is the premise behind Duplicate Photo Fixer, which is designed to filter through your photo collection in search of double takes.

A. Make your photos shine.

B. The app gathers that data in one place, letting you decide what to keep.

C. This aim of this app is to clean your smartphones.

D. Remove redundant images.

E. When you download the app, you can focus on a specific browsers that you would like to clean up.

F. Here are three tools that can help you organize your virtual (and real) environments.

G. The trick is to safely delete redundant photos without losing the original image.

    What is your favourite colour? Do you like yellow, orange, red? {#blank#}1{#/blank#} Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead． You tend to be pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings.{#blank#}2{#/blank#} If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

    {#blank#}3{#/blank#} A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day.{#blank#}4{#/blank#} A black bridge over the Thames River, near London, used to be the scene of more suicides(自杀) than any other bridge in the area——until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

    {#blank#}5{#/blank#} It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

A. On the other hand, black is depressing.

B. They tell us, among other facts, that we do not choose our favourite colour as grow up——we are born with our preference.

C. The rooms are painted in different colours as you like.

D. If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.

E. Light and bright colours make people not only happier but more active.

F. Life is like a picture or a poem, full of different colours.

G. Colours do influence our moods—there is no doubt about it.

    On December 22, 2016 I landed in the land of the “American Dream.” {#blank#}1{#/blank#} Here is one of the things I've struggled with during my almost one year in the States.

{#blank#}2{#/blank#} My uncle and aunt joked that I brought rain from Saigon to America. Saigon, where I come from, is the old name of Ho Chi Minh City in Vietnam. Vietnam is a tropical country where it rains most of the year. Before going to the U.S., actually, I had no idea what to expect about its weather, but the big rain on my arrival gave me the first expectation of what the weather here might be like.

    California is known for having a great climate — more sunshine, cooler in summer and warmer in winter. {#blank#}3{#/blank#} However, having been here for a pretty long while now, I have experienced various forms of climate in California.

    {#blank#}4{#/blank#} Most of the time I was living in Silicon Valley, where the weather is a bit colder than where I study in Orange County. But I was really surprised to find chill-to-the-bone weather in San Francisco — a big shift from Silicon Valley in only about an hour's drive. How strange!

    {#blank#}5{#/blank#} The worst is that I get n runny nose whenever I wake up in the morning. Because I am allergic to the cold and windy weathers, I keep sneezing badly, and even more badly if I get caught in the cold. I think that my body needs more time to get used to this climate, but as many people said, I am luckier to be in California where I don't have to fight with extreme weathers as in other states.

A. I am sensitive to weather change.

B. Such strange weather has affected my health.

C. So the amount of rain this year is considered unusual.

D. LAX airport in California welcomed me with a big rain.

E. So I quickly get used to the unchangeable climate in California.

F. The weather varies widely depending on where you are in the state.

G. Since then, I have discovered tons of dilemmas about life in America.

    Air pollution is a killer. The World Health Organization says it kills an estimated seven million people around the world each year.{#blank#}1{#/blank#} , it can make us very sick.

    However, breathing dirty air may do more than hurt your body.{#blank#}2{#/blank#} .A new study shows that air pollution can cause a “huge” reduction in our intelligence. The researchers reposed that long-time exposure to air pollution can affect a person's mental abilities in two areas: language and mathematics.

    {#blank#}3{#/blank#} .Between 2010 and 2014, these Chinese men, women and children were given language and math tests. Then they compared the test results with measurements of pollution in the air, namely nitrogen dioxide and sulfur dioxide, and found that breathing polluted air can reduce a person's education level by about one year.

    It has found that the effect generally is worse for those over 64 years of age, for men and for those with little or no education.

    “{#blank#}4{#/blank#} .And we find, quite interestingly, males are more affected than females. And people working outdoors are more affected than people working indoors, ”one of researchers said.

    He noted that the youngest people in the study were 10 years old, while the oldest was 90.They came from 25 of China'S 33 provinces.{#blank#}5{#/blank#}.

    The researchers also noted that the effect of pollution on verbal ability is even more serious as people age, especially among men and the less educated.

A. Even if polluted air does not kill us

B. The elderly people are more affected

C. Therefore, some measures should be taken

D. Air pollution is one of the major problems of China

E. It can also affect your brain and your ability to think

F. The researchers studied about 25, 000 people across China

G. This range of ages and locations provided a “good representative sample”

    In the 60s, people asked about your astrological (about star) sign. In the 90s, they want to know your website. {#blank#}1{#/blank#} Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The Web is filled with all kinds of free services and all it takes is some time and creativity.

    {#blank#}2{#/blank#} Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.

    While web pages vary greatly in their design and content, most use a traditional magazine layout (版面设计). At the top of the page is a banner (横幅) GRAPHIC. Next comes a greeting and short description of the site. Pictures, text, and links to other websites follow.

    {#blank#}3{#/blank#} Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site.

    While there are no rules you have to follow, there are a few things to keep in mind: {#blank#}4{#/blank#} If you want too much at the beginning, you may never get the site off the ground. You can always add to your site.

    Less is better. Most people don't like to read a lot of long texts online. {#blank#}5{#/blank#}

    Smaller is better. Since it can take a long time to download large files, keep the file sizes small.

    Have the rights. Don't put any material on your site unless you are sure you can do it legally. Always remember to get the permission from the writer first.

    Now it's time to roll up your sleeves and start building.

    The UN's Millennium Development Goals included the ambition that by 2015 all the world's children would complete primary school. This has largely been achieved: nine out of ten children are now enrolled. {#blank#}1{#/blank#} Even though most of the world's children go to school, an awful lot of them learn pretty much nothing there. According to a recent World Bank study of seven sub-Saharan African countries, half of nine-year-olds cannot read a simple word and three-quarters cannot read a simple sentence. {#blank#}2{#/blank#}

    Several recent studies suggest education technology can help  It seems to bring about bigger improvements in poor countries than in rich ones.

    {#blank#}3{#/blank#} That doesn't mean buying computers for schools in the hope that children will understand how to use them, a stupidity on which plenty of money has been wasted. Instead, it means providing schools with software that children can use with minimal help from an adult. The software gets things right more often than the teachers do, adjusts itself to the child's ability, and sends teachers instructions about what they are supposed to be teaching. {#blank#}4{#/blank#}

    Technology is no panacea(万灵药) . {#blank#}5{#/blank#} And authorities need to take teachers into account. But education technology can help greatly — by monitoring pupils and teachers alike, assisting the best teachers and, most important, making up for the failings of the worst.

A. The reason is terrible teaching.

B. The achievements are really great.

C. However, the figure is not as impressive as it sounds.

D. Technology plays more and more important role in teaching.

E. Good traditional teachers are not outdated, and are never likely to be.

F. Meanwhile it allows the authorities to check on whether the teacher is in the classroom.

G. Some of the scarce resources being spent on teachers could therefore be better spent on education technology.
