Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．{#blank#}2{#/blank#}So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

 Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．{#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

 A．Modern people used to suffer from "diseases of civilization".

 B．People today probably don't want to live like our ancestors.

 C．These new sicknesses were not known in ancient times.

 D．Ancient people also got lots of physical exercise.

 E．In that case, they would live much healthier.

 F．But today, we enjoy eating a lot of these.

 G．Stone Age people lived a simple life.

    The first time I went abroad was when I went to London. It was in the summer holidays about five or six years ago and I went with my friends. {#blank#}1{#/blank#}, so we decided to travel by coach. We left at five in the morning and the journey to London took about sixteen hours.

    We stayed in London for three days, in a youth hotel not far from the centre. {#blank#}2{#/blank#}. the beds were not very comfortable and the bedroom was very small but it had a wonderful view overlooking the Thames.

    {#blank#}3{#/blank#}. First, we went to see all the famous sites: Big Ben, Piccadilly Circus, and Buckingham Palace. Then we went shopping in Oxford Street. On the last day my friends and I went to Camden market. You can buy all kinds of jewelry and clothes there.{#blank#}4{#/blank#}. it was really sunny in the afternoon, so we went to watch a football game. Unfortunately, I think the ring fell out of my pocket during the game, and I had to buy another one.

    {#blank#}5{#/blank#} although the youth hotel was not perfect. Next time, I will stay at the Ritz but I will never feel as excited as I did that first time.

G. I've been back to London several times since then

    Public Speaking Training

    Get a coach

{#blank#}1{#/blank#} so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.

    Focus on positives

Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well.{#blank#}2{#/blank#} so good public speaking training should develop those instead of telling you what you shouldn't do.

    {#blank#}3{#/blank#}

If you find a public speaking course that looks as though it's going to give you lots of dos and don'ts, walk away! Your brain is so full of what you're going to be talking about.{#blank#}4{#/blank#} As far as we're concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.

    You are a special person not a clone (克隆人)

Most importantly, good public speaking training should treat you as a special one, with your own personal habits.{#blank#}5{#/blank#}Your training course should help you bring out your personality, not try to turn you into someone you're not.

A. You aren't like anybody else

B. You already do lots of things well

C. Turn your back on too many rules

D. Check the rules about dos and don'ts

E. Whatever the presentation, public speaking is tough

F. The one thing you don't want is for them to fall asleep

G. So trying to force a whole set of rules into it will just make things worse

    My friends and I had one-week trip to Bali Island in June three months ago, which was really impressive.

    It wasn't the typical trip by the sea with swimming suit at the beach. {#blank#}1{#/blank#} The rest of the days we would practice what we had learnt from the video with our coach, first in the pool, and then in the sea. Every day we had to dress ourselves up in the tight diving suit and a jacket with a heavy steel tank on the back

    I wasn't how most people would imagine spending their holiday. {#blank#}2{#/blank#} Not only did we appreciate beautiful view under the ocean, but we also felt less like tourists and more like professional divers as we learn more skills each day. This was more than just diving in life jackets. We were able to get away and explore underwater, swimming with turtles and other beautiful sea creatures in the ocean. “There are no mobile phones down there, no emails, no keys to lose, no birthdays to forget… {#blank#}3{#/blank#} The ocean is the last quiet place on Earth,” as a US journalist wrote in his book DEEP.

    {#blank#}4{#/blank#} When we had to fully concentrate on our breathing, we started to realized how we had been taking it for granted. We had never truly “felt” ourselves breathe before.

    {#blank#}5{#/blank#} In fact, my friends and I are already planning another diving trip to the Red Sea in the coming winter holiday. Why not join us?

A. Of course we had dived in the sea before.

B. However, we really enjoyed every minute of it.

C. It's said that diving can be attractive yet I was unsure about it.

D. The experience also allowed us to get to know ourselves better.

E. All stress, noise and troubles of life are left at the surface of the sea.

F. I've become interested in diving and have no doubt about the attraction of diving.

G. Instead, we spent our first morning siting in a room watching teaching videos about diving.

    Do you want to be at the top of your class？Add these tips to your life and you should be on your way to being a top student!

    {#blank#}1{#/blank#} I cannot stress enough how important it is to pay attention to what your teacher is teaching you. Take part in class discussions if you have something worthwhile to add. Pay attention during class，especially during lectures.

    Taking notes is important. You don't need to write down every word your teacher says but write down what he/she writes on the board，or any special fact you think you might need for a test.{#blank#}2{#/blank#} This way it will help you learn more effectively by actually thinking about what you are writing.

    Don't skip school. You will missing out on stuff.{#blank#}3{#/blank#}However，you will have more work because you have missed lectures and in-class movies. Also，try not to be late for class. It's most likely that your teachers won't appreciate it and you will get yourself behind.

    {#blank#}4{#/blank#} If you have an "I don't care about school or this class" attitude，then teachers will be less willing to help you with problems or offer you extra credit(学分).The same goes for lazy attitude. Have a respectful attitude to the teacher and other students. Try not to laugh when other students make a mistake.

    Always ask questions.{#blank#}5{#/blank#} If you don't understand，ask someone. Read your textbook and notes，and then if that fails，seek help. Ask a teacher，friend，classmate，parent, ect. Get a tutor if you need one.

A. Be prepared.

B. Staying organized will be helpful.

C. Write in your own words.

D. It is true that you could make up the work.

E. Pay attention to everything the teacher says.

F. Keep a good attitude toward things.

G. There is no shame in needing some help.
