Everyone knows that fish is good for health. {#blank#}1{#/blank#} But it seems that many people don't cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn't difficult. {#blank#}2{#/blank#} This text is about how to buy and cook fish inan easy way.

Frozen fish isn't as tasty as the fresh one.

         There are many common methods used to cook fish. {#blank#}5{#/blank#}First, lean it and season it with your choiceof spices(调料).

    Global Positioning System (GPS) is now a part of everyday driving in many countries. It is a space-based system that provides position and time information in all weather conditions. GPS can help people get to where they want to go.{#blank#}1{#/blank#}When this happens, the driver is often to blame. Sometimes a GPS error is responsible. Most often, it is a combination of the two.

    {#blank#}2{#/blank#}Barry Brown, a GPS technologist, took an incident as an example. His friend once flew to an airport in the eastern United States. There he borrowed a GPS-equipped car to use. He wrongly plugged in the home address in the west. It wasn't until he was driving for thirty minutes that he realized it. Mr. Brown says this is a common human error. But he says, “One problem is that GPS has a very small screen and it can just tell you the next turn.{#blank#}3{#/blank#}”

    “The Normal and Natural Troubles of Driving with GPS” lists several areas where GPS can cause difficulties. They include maps that are outdated, incorrect or difficult to understand. {#blank#}4{#/blank#}GPS may fail due to these reasons and then lead to confusion for the drivers.

    Although GPS sometimes causes difficulties when people are driving, the most attractive point of this system is its 100% coverage on the planet. It is important for you to have to know what you are doing when you use GPS. You need to have the “ability” to be able to use GPS because it sometimes goes wrong.{#blank#}5{#/blank#}

A. There are quite a few situations showing the problems of using GPS.

B. That means that it is not really telling you about going to the wrong place.

C. This space-based system is an important tool for civil and commercial users.

D. But sometimes it sends you to the wrong place or leaves you completely lost.

E. They also contain timing problems related to when GPS commands are given.

F. Advances in technology play an active role in modernizing GPS in many ways.

G. To make GPS well used, you need a good understanding of how drivers and GPS work.

    Of all nature's disasters, forest fires are often considered the most frightening. Moving at lightning speed, huge walls of flames can burn acres of land in just a few minutes. And although technology, including the use of fire-retardant chemicals, has greatly helped the fight against forest fires, they still do great damage.

    According to the National Interagency Fire Center, the fire season last year was the worst on record in terms of the number of fires and acres burned. There were 96. 385 fires and 9.873429 acres affected by fire in a year that was 125% more destructive(毁灭性的) than the10-year average. These fires cost the federal government $1.5 billion to fight, and this figure does not include the money spent by local and state governments as part of the effort.

    Fires in the southern states represented half of the national total last year with Texas, Oklahoma and Arkansas being home to a usually high amount of activity. Wildfire has also taken place in Western states such as California, Colorado and Alaska throughout the past 10 years.

    It is said that two-thirds of forest fires are started accidentally by people. Almost one quarter are purposely set, while lighting causes 10%.

    Forest fires can have advantageous effects. Charcoal(木炭) enriches soil and some plant species(种类) grow well after fire. The cones of the jack pine tree, for example, will not spread their seeds unless there is heat. Douglas fir trees grow best in open sunlight areas after fire.

    People all need friends because nobody wants to be lonely and a friend can help you in good and bad times. You have made friends since childhood, but you still don't know who your true friends are. Here are some signs to tell you if your friend is a true friend:

Always honest

    Honesty is important to keep a relationship alive. A true friend always tells you the truth. It may be hard sometimes but lying can destroy a friendship. It is important that your friend speaks honestly and never makes up stories.

    There are always periods in your life when you have problems or difficulties. A true friend will always have time to listen to your problems and give advice. It may not be able to offer a solution to your problems but the fact that your friend made time to listen is a sign he/she cares for you. Your friend is not a true friend if he/she can never make time for you when you are in trouble. You also need to be reasonable and accept that your friend also has other things to do so he/she can't always listen immediately to your problems.

Always respectful (尊敬的)

    A true friend will always respect your opinion no matter whether he/she agrees or not. Your true friend may disagree but never insists that he/she is correct.

Always understanding

    It is possible that some problems will arise between you and your friend. A true friend will always be forgiving (体谅的) and understanding even if it isn't his/her fault. We are all different people and we all make mistakes. A true friend is always forgiving and understanding because he/she doesn't want to take the risk of losing his/her best friend.

    Have you ever imagined the benefits that a good memory can bring to you? {#blank#}1{#/blank#} Here are four ways to improve your memory.

    {#blank#}2{#/blank#} There is evidence that sleep plays a vital role in the consolidation of memories relating to learning motor skills, such as learning to play a musical instrument or ride a bike. Having a full night's sleep soon after gaining a new skill helps consolidate the processes involved, so they can later be performed well.

    It's rewarding to continue education. Older people are often told to adopt a “use it or lose it” approach to maintaining cognitive (认知的) function. {#blank#}3{#/blank#} In a 2016 study, US researchers found participants aged 60-90 who spent 15 hours a week for three months learning a complex skill, such as digital photography, saw significant improvements in memory tests.

    Taking a break counts. {#blank#}4{#/blank#} More than a century ago, German scientists showed that people performed almost twice as well in memory tests if they took breaks.

It's useful to stay social. Having an active social life delays memory loss as we age, US scientists who asked people in their 50s and 60s to do memory tests every other year between 2001 and 2007 found the decline in recall abilities of their most sociable subjects to be half that of the least well connected. {#blank#}5{#/blank#}

A. Sleeping well helps strengthen memories.

B. Old people should participate in easy activities

C. Yoga, meditation or other relaxation techniques may help.

D. Memories can be destroyed if the brain doesn't have enough rests to sharpen them.

E. In fact, when it comes to memory, research suggests that only certain types of mental activities help.

F. Being able to remember important pieces of information can give you a powerful advantage in your life.

G. Having good friends, volunteering for charities and other forms of social engagement also protect memory.

    Note: Please keep in mind that the steps might vary from device to device.

    Install (安装) the "Move to iOS" App on your Android device from the Google play store. This application is developed by Apple and available for free.

    Once you are done with installing the app, you need to grant permissions to the app. Now, follow on-screen instructions to proceed.

    Now, keep your Android aside and start your iPhone. Follow the on-screen instructions to set up your iPhone.

    The transfer might take a bit longer depending upon the size of the content.

    On your iPhone screen, you will see a screen saying," Continue setting up iPhone".

    You can continue setting up your Apple ID on your new iPhone. Once done, you will find all your data such as contacts, messages, bookmarks, pictures etc. on it.

    That's it, now you can dump your old Android phone and enjoy using your iPhone.
