A. Come in with something to say.

B. Prepare general comments.

C. Bring materials with you.

D. Don't make them wait.

E. Have no fear.

F. Go it alone.

One of the best things you can do any time in the semester is go see the professor. So hoof on over to an office hour and have some one-on-one face time with someone who'll help you master the material and improve your grade, to boot. But how should you have this conversation with the professor? Here are five insider tips about how to make that office hour really count:

{#blank#}1{#/blank#} No need to get all bent out of shape about going to see the professor. The professor would actually like to see you and answer your questions. Believe it or not, he or she is on your side and is eager to see you do well. And besides, he or she has seen many students stupider than you, so nothing you're gong to ask will set the record for stupidity.

{#blank#}2{#/blank#} Even though you might feel more comfortable going with a friend or partner, the office hour will go better if it's just you and the professor. You'll get in more questions, the discussion will be tailored to what you need most help on, and two-party communication is almost always more productive than committee work. You friend can wait outside for the discussion.

{#blank#}3{#/blank#} If you can't make the official office hours, most professors are willing to make individual, appoin tments to help you out. If you're lucky enough to land such an accommodation, though, be sure you're 100 percent on time. There's nothing that ticks off a professor more than making him-or herself available for a custom office hour only to find that you don't care enough to come on time. And besides, the professor might leave after ten minutes, which would make your trip a total loss.

{#blank#}4{#/blank#} If you're meeting with the professor to go over a paper or test, or to ask questions about a particular lecture or reading, make sure you bring that paper or test, or your lecture notes or a copy of the article. The professor doesn't remember the comments he or she wrote on your individual piece of work—though he or she will be able to recall them after just a brief glance at your work. And if you have your lecture notes or the article in hand, you and the professor will be able to examine specific points that are confusing to you, rather than just talking in a general way about the contents.

{#blank#}5{#/blank#} Office hours almost always go better if you bring a few specific questions to the meeting. It's almost never good to start a meeting with general comments such as: “I didn't understand what you said about [main topic of the course]”or “I couldn't understand any of your lectures last week.” Much better is to come in with two or three conversation-starters, about a specific concept, point, or problem you didn't understand. Keep in mind that in a fifteen-minute office hour (which is how long these things usually last), two or three questions are usually the most you'll have time to discuss.

    Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying. {#blank#}1{#/blank#} However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace (支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

    Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the "ten and two" position.

    Undo your seatbelt. {#blank#}2{#/blank#} Untie the children, starting with the oldest first. Forget the cell phone call. Your car isn't going to wait for you to make the call.

    {#blank#}3{#/blank#} Leave the door alone at this stage and concentrate on the window. A car's electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking.

    Break the window. If you aren't able to open the window, or it only opens halfway, you'll need to break it with an object or your foot. It may feel counter-intuitive (有悖常理的) to let water into the car. {#blank#}4{#/blank#}

    Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival. {#blank#}5{#/blank#} While there is still air in the car, take slow, deep breaths and focus on what you're doing.

A. Open the window as soon as you hit the water.

B. Surviving a sinking car is not as difficult as you think.

C. It takes 60 to 120 seconds for a car to fill up with water usually.

D. Such accidents are particularly dangerous to the risk of drowning.

E. In conclusion, if you know what to do in the water, you will be safe.

F. This is the first thing to attend to, yet it often gets forgotten in the panic.

G. But the sooner the window is open, the sooner you can escape directly through it.

A memorable science project

    If someone tells you to remember a phone number or address, it feels like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds you might find yourself starting to doubt your own memory.{#blank#}1{#/blank#}Thus, it will try to throw away information that seems old or irrelevant. There are ways of helping our minds retain (记住) information, however, and in this activity you will explore ways that we lose and keep memories.

    Short-term, or working memory, is a way of describing most people's abilities to store a small amount of information for a brief period of time in a readily accessible form{#blank#}2{#/blank#} People don't have to stop and think to remember something in short term memory.

    {#blank#}3{#/blank#}Such techniques include visualizing (观察) the information in a surprising way or linking pieces of information together so that one reminds you of the other. In the case of visualizing information, this could be as simple as remembering you parked your car on the fifth floor in the D section by picturing five dogs sitting in your car!{#blank#}4{#/blank#} If you need to purchase cereal (谷物), milk, fruit, cheese and eggs, you could imagine the cereal in a bowl, with milk pouring over it and pieces of fruit on top. Then imagine cracking an egg over everything, and it's full of melted cheese! These may seem simple or even silly.{#blank#}5{#/blank#} In this activity you'll test the recall of a few friends or family members, and learn a few tricks for improving memory!

A. There are many techniques for improving memory.

B. Our brain is always seeking new and useful information.

C. Short-term memory has a short duration but is quickly and easily accessed.

D. In addition, linking information could help you remember your grocery list.

E. Retaining that information over longer periods of time becomes difficult yet.

F. Your short-term memory has a limited amount of space to store information.

G. However, they are proved to be good ways for improving memory by scientist.

    Gratitude(感恩)is a social feeling．Many people see it as relationship—strengthening because it requires us to see how we've been supported and recognized by other people．

    First，it's belief of goodness．We are convinced that there are good things in the world，gifts and benefits we've received．The second part of gratitude is figuring out where that goodness comes from{#blank#}1{#/blank#} It doesn't come from anything we necessarily did ourselves．Instead，we acknowledge that other people gave us many gifts to help us achieve the goodness in our lives{#blank#}2{#/blank#}Of course，there are various important reasons．Here are some of them．

    Gratitude allows us to celebrate the present{#blank#}3{#/blank#}We notice the positives more，and that enlarge the pleasures you get from life．Instead of adapting to goodness，we celebrate goodness．

    Gratitude blocks negative feelings．You cannot feel envious and grateful at the same time{#blank#}4{#/blank#} If you're grateful，you can't hate someone for having something that you don't．Those are very different ways of connecting to the world，and sure enough，research has suggested that people who have high levels of gratitude have low levels of negative feelings．

    {#blank#}5{#/blank#}That's because when you're grateful，you have the sense that someone else has provided for your happiness．You notice a network of relationships of people think it's worthwhile to help you get to where you are right now．Realizing someone has seen the value in you transforms the way you see yourself．

A．They're contradictory feelings．

B．It strengthens positive feelings．

C．Gratitude heightens your sense of self-worth．

D．Most of the time，it makes you feel confused．

E．Gratitude allows us to participate more in life．

F．So why gratitude has such effects on people's lives?

G．We recognize the sources of it as being outside of ourselves．

    With 17 million residents and 23 million bicycles, the Netherlands already has more bikes than people.{#blank#}1{#/blank#}.

    The Dutch government recently announced that it will invest $ 390 million in cycling infrastructure to get 200, 000 more people commuting(通勤)by bike in three years time. Fifteen routes will be developed into “cyclist freeways”, 25, 000 bike parking spaces will be created and more than 60 bike storage facilities will be upgraded.

    “{#blank#}2{#/blank#},”says Stientje van Veldhoven, state secretary for that department, who is spearheading the project.

    It's not that people aren't already cycling in the Netherlands. In 2016, over a quarter of all trips made by Dutch residents were by bike. But only 25％of those trips were work—related, compared to 37％which were made for leisure. {#blank#}3{#/blank#}.

    According to van Veldhoven, more than 50％of people in the Netherlands live less than 15 kilometers from work, and more than half of commuters car trips are under 7.5 kilometers long—a distance that “can easily be covered by bike, ”she says.

    {#blank#}4{#/blank#}. The Netherlands currently rewards commuting cyclists with tax credits of $0.22 per kilometer. Companies and employees would agree on the distance of a person's cycling route.

    However, this is currently a little—known benefit not supported by many employers, according to the infrastructure ministry. That's something the government is hoping to change by better promoting the scheme and getting more companies on board. {#blank#}5{#/blank#}. The government is urging employers to provide better facilities for commuting cyclists, such as showers at the office, according to the ministry.

A. The rest were for school, shopping, or other activities

B. To get people to ditch their cars, money is being laid on the table

C. Now, it wants to get even more cyclists on the roads—and will pay people to do it

D. Today the Netherlands is known for its cycling culture, but that hasn't always been the case

E. My ambition is to ensure that people can easily get to work or school, or visit family and friends

F. The Netherlands is now one of the few countries that takes cycling seriously as a mode of transportation

G. There are already 11 major employers in the Netherlands committing to measures such as financing employees' bikes
