【题目】 The chief problem in dealing with foreign motorists is not so much remembering that they are different from you, but that they are largely variable. Cross a frontier(边境) without adjusting and you can be in deep trouble.

One of the greatest gulfs separating the driving nations is the Atlantic Ocean. Or rather, it is the mental distance between the European and the American motorist, particularly the South American motorist. Compare, for example, an English driver at a set of traffic lights with a Brazilian.

Very rarely will an Englishman try to anticipate(预先准备) the green light by moving off. You will find the occasional someone who watches for the yellow light to come up on the set of lights. However, he will not go until he receives the lawful signal. Brazilians view the thing quite differently. If, in fact, they see traffic lights, they regard them as a kind of roadside decoration.

The natives of North America are much more disciplined. They show this in their addiction to driving in one lane(车道) and sticking to it—even if it means settling behind some great truck for many miles.

To prevent other drivers from falling into wrong ways, American motorists try always to stay close behind the vehicle in front which can make it impossible to make a real lane change. European visitors are always falling into this trap. They return to the Old World still waving their arms in disappointment because while driving in the State in their cars they kept failing to get off the highway when they wanted to and were swept along to the next city.

However, one nation above all others lives cautiously by its traffic regulations — the Swiss. In Switzerland, if you were simply to anticipate a traffic light, the chances are that the motorist behind you would take your number and report you to the police. There are slight regional variations among the French, German and Italian speaking areas, but it is generally safe to assume that any car bearing a CH sticker will be driven with a high degree of discipline.

1How do American drivers behave on the road according to the passage?

A.They run the red light sometimes.

B.They drive close behind other drivers.

C.They care little about the traffic light.

D.They start their car at the yellow light.

2Which people take the traffic light most seriously?

A.The Swiss.B.The Brazilians.

C.The English.D.The French.

3The passage is mainly developed by ____.

A.analyzing causesB.describing changes

C.making comparisonsD.pointing out similarities

4Which part of a newspaper is the passage probably taken from?

A.Culture.B.Business.

C.Entertainment.D.Geography.

【题目】 There is an English saying, '1' Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. 2

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise.3 If laughter exercises the body, it must be beneficial.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the group which listened to a funny program. 4

5They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A.Laughter can surely last one's life.

B.As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients' condition by encouraging them to laugh.

C.The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.

D.It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet.

E.They have proved that laughter can really cure any disease if people keep a good state of mind.

F.Laughter is the best medicine.

G.They have found that laughter really can improve people's health.

【题目】 Porridge doesn't have a very tasty name, does it? It doesn't have a very tasty reputation, either. I'm here to try and convince you that porridge isn’t boring and tasteless, that it can be a delicious, convenient and very healthy way to start the day.

If you’ve never eaten it (although you probably have), porridge is a type of food served for breakfast. It is usually a type of grain, like rice or oat (燕麦), mixed with either milk or water, and often heated up. It is often thicker than liquid, but not solid and is very easy to digest, so it's a better option for people who are ill, and it provides long-lasting energy for the day.

Porridge preparation--the amount of ingredients (配料) and cooking time—depends on what you choose to use as your porridge base. If I'm cooking for myself, I put a very big handful of ‘rolled’ oats in a saucepan, add a little bit of water and about 200ml of milk, and let the mixture boil. I stir the porridge constantly, and it takes about five to ten minutes to cook.

Once it's cooked, the fun part is adding the flavors. Porridge alone doesn't have a very strong flavour. Although some people think this makes porridge boring, I think this is what makes porridge exciting! It is like a blank piece of paper—you can add almost anything you want to the porridge base. Greens, nuts and dried fruits are very healthy options to add and can give you energy for the day. But if you don't like these, or you're allergic, then honey and chocolate are also very tasty options. (Just don’t add to much!)

One of the best things about porridge? You can make it almost anywhere in the world. Either oats or rice or both are “staple foods (主食)” for many people across the world. You can usually buy big bags of either, then add local ingredients to make your porridge interesting—whatever is cheap and convenient to find, wherever you are. I am currently in Mexico, and I love to heat my oats up with milk, then mix in peanuts and pumpkin seeds and cacao nibs, and I put a layer of sugar over the top to make my porridge sweeter.

Porridge? Hopefully it sounds a lot tastier now!

1What is the purpose of the text?

A.To give brief introduction to various porridge.

B.To show how to prepare porridge for the patient.

C.To warn us not to have porridge for breakfast.

D.To introduce the benefits of porridge.

2Which of the following statements is TRUE?

A.Porridge is often thicker, liquid and solid.

B.Porridge alone has a very strong flavor.

C.Porridge is to many people's liking.

D.Porridge is only served for breakfast.

3According to the author, what is the best thing about porridge?

A.It provides long-lasting energy for the day.

B.It is cheap and convenient to make.

C.It's a better option for people.

D.It is never boring and tasteless.

4What's the author's favourite flavor?

A.Porridge with Sugar.B.Porridge with oats.

C.Porridge with fruit.D.Porridge with milk.

注意:每个空格只填1个单词。请将答案写在答题卡上相应题号的横线上。

Success Takes Focus

You can have a strong desire and really want to achieve your goal but as you’ve experienced, life has its way of knocking us off course. Things come up, and distractions occur.

Success takes a lot of focus. You’ve had the experience of setting a goal and being really excited about achieving it only to have a few weeks or months to go by and realize the goal has dropped down on your list of priorities.

People often get easily side tracked. This doesn’t just happen all at once. You get off track just little by little until one day, you realize you’re completely off track. Keeping your mind focused on your goal can be a constant battle because everything around you is trying to get your attention. It will be your job to keep your goal up high on your priorities list.

So what can you do to keep your focus? There are several things you can try. You can write down your goal and read it each morning and night. You can visualize achieving your goal daily.

One of my favorite methods of keeping focused on a goal is to constantly ask myself, “Is what I’m doing right now bringing me closer to my goal or further away?” Once you answer that question, you’ll know what to do. You can make sure that your daily to-do list includes doing something that will take you closer to your goal.

If you look back at the goals you’ve tried to achieve and realized you haven’t achieved any of your major goals, it may be time to just focus on a single goal. This way, all of your energy and focus can be put towards obtaining that one goal which will increase your chances of getting it. It’s a lot better to just achieve one major goal than to work on a dozen and achieve none of them.

Remember that you’re human and because of this, you’ll make some errors in judgment. Instead of beating yourself up, just be aware that certain things can take your focus away from your goals. Once you’re aware of these things, you can actively reduce the amount of time they take your focus off your goals.

Distractions are like gravity. It’s going to cause us all to fall every now and then. The important thing is that we bounce back up every time we fall. Get your focus back on your goal when you start to realize it’s drifting somewhere else.

Passage outline

Supporting details

A common phenomenon

Achieving your goal requires much 1, but distractions are a barrier to your success.

The way it happens

Getting side tracked is a 2 process, and you have to battle against getting off track 3.

4 on solving the problem

◆You can 5 yourself of your goal by writing it

down, reading it every morning and imagining achieving it.

◆ Make sure what you do helps you get 6 to your goal.

◆ Focusing on a single goal makes you more 7 to achieve it.

◆ Don’t blame yourself, as it is 8 for humans to make wrong judgement.

Accept the fact that distractions are 9 to happen and try to reduce the time of getting distracted.

Summary

Distractions can be compared to 10 causing us all to fall often, in which case we should bounce back to our goal timely.
