【题目】Not only fashion and music are making a return—houses built in 1970s have proven to be better at cutting energy waste than those built today. The “tea cosy (茶壶套)” design, created in the mid-1970s and built in the early 1980s for low-income people, could provide a blueprint for meeting the Government aims of producing less CO2 from homes.

The 200 houses were designed to provide low-energy housing, and depend on an inner concrete (水泥) structure that holds in heat, protected by highly insulated (隔热的) setting which produces a “tea cosy” effect. The ordinary-looking houses also depend on more windows on south-facing sides, with northerly facing doors protected by porches (门廊).

A study found the houses are 50 percent more energy efficient than the average home and use a quarter of the average energy for space heating. According to researchers, they use less than two-thirds of the power of homes built to meet 2010 building demands. And they will still be 25 percent more efficient than houses built to even more strict proposed demands for 2013. The design is one of the few that will be able to meet 2016 demands for zero-carbon homes.

They were in the beginning fixed with just one or two gas heaters per home, although most now have central heating, depending on the heat from the sun and high insulation to keep steady temperatures inside the house. To be comfortable, they only need to use heating for three to four months a year, compared with seven months for UK home on average, and can be lived with no heating at all.

With many house builders at present worrying that new homes are going to be much more expensive to build in order to meet the Government’s ambitious targets, the“tea cosy”model meets this need perfectly.

【题目】A California man who was feeling sick almost died recently from a shocking cause.

26-year-old Luis Ortiz went to a hospital because of a headache and nausea(恶心，作呕). When doctors examined him, they were shocked to find a tapeworm larva(绦虫幼虫) in his brain. The story gets stranger. The larva was still alive.

The creature had caused a cyst(囊肿) to form inside his head. The cyst was restricting the flow of liquids to different areas of his brain. The situation was so serious that doctors said they had to perform an emergency operation to remove the larva.

A doctor who operated on Ortiz told him he had only 30 minutes to live. When the doctor pulled the worm out of his head, it was still moving.

Luis Ortiz was a student at California State University in Sacramento. He began experiencing headaches in late August. But Ortiz said he did not think the headaches were serious.

In September, he visited a friend and his parents in another city. That is when the pain got worse. His mother saw Ortiz throwing up and took him to a hospital emergency room.

The doctors saved Ortiz's life. However, the surgery also affected him. Ortiz had to drop out of school and move back home. For now, he is not permitted to work or drive a vehicle.

The U.S. Centers for Disease Control and Prevention says the U.S. has about 1,000 reported cases of tapeworms each year. The CDC adds that tapeworms are more common in developing countries with poor public health systems.

The best way to avoid a tapeworm infection (感染)is to wash fruits and vegetables. Also, make sure meat is cooked thoroughly. The CDC suggests cooking all meats to an internal temperature of at least 63 degrees Celsius.

【1】 What caused Luis Ortiz to feel sick and headaches?

A. Dirty food eaten in August.

B. Travelling for a long way,

C. A living creature in his brain.

D. Uncooked meat eaten by him.

【2】If the doctors didn’t have an emergency operation on him , Luis Ortiz was likely to ________ _ .

A. die of cancer B. live for only half an hour

C. finish studying in school D. pass the driving tests

【3】 How should people avoid infecting tapeworms?

A. By washing fruits and vegetable.

B. By boiling plates and bowls before meals.

C. By cooking meats to at least 63 °C outside,

D. By improving the development of economy.

【4】 What did the writer think of the cause of Luis Ortiz’s disease?

A. Quite frightening. B. Very dangerous.

C. Rather puzzling. D. Extremely surprising.

【题目】Investing in yourself

Figuring out how to invest your money can be a difficult task. This is something that you will want to learn how to do.

【1】Things that will improve your knowledge, skills or health are all great investments. However, before you start, you need to be clear about what you will gain out of doing all of these things.

You may think investing in yourself means investing in your education.【2】 There are some other things you can do as well as buying a gym membership or learning a new skill.

So what are some specific things you can do? 【3】. Reading books can really expand your mind and allow you to learn different skills and gain knowledge. I’m talking about the books where you will actually learn a new skill, not fiction books. You can also take courses and attend seminars. These programs are taught by people with a high level of knowledge or skill. 【4】. Only in this way can you avoid being fooled by some sales presentation. Moreover, investing in yourself is a safe way to keep your money. Although a savings account is seen as the most secure investment, that isn’t 100% safe. Even if you never experience your bank closing down, the return is little when inflation(通货膨胀) is taken into consideration.【5】. But over time, they will show up in terms of your happiness level as well as your level of success.

A. This is just one way.

B. The benefits will stay with you.

C. If you aren’t a reader, you should start with that.

D. The more you do this, the more valuable you will be.

E. Of course, you need to do some research before investing.

F. The best way to invest your money is to invest it in yourself.

G. When you invest in yourself, you may not see gains right away.

根据短文内容，从短文后的七个选项中选出能填人空白处的最佳选项。选项中有两项为多余选项。

We all go through times when we feel we are not good enough. We might feel that way at work or in school or even as a parent. Here are some things to remember when you feel like that.

1. —【1】—. When I started my Ph.D. program, I felt like the dumbest person in every class. I couldn’t believe how many smart people were there. I didn’t know if I could measure up to their intelligence or compete in the same league with them. Years later, I found out that almost everyone felt this way, too.

2. You are unique and have special talents. If you can barely make Hamburger Helper, don’t compare yourself to your sister who is a chef(厨师). I’m sure you can do many things that she can’t. —【2】—. You are you. You are not your sister.

3. You need to stop chasing perfection. It doesn’t exist. —【3】—. So if you think that there is some objective measurement of perfection and that the rest of the world is judging you against, then you are wrong. Most people are too worried about their own lack of perfection to judge you.

4. —【4】—. Our sense of self-worth is based in our thoughts. We have been programmed for many years with thoughts about ourselves. Messages come from our parents, our peers, teachers, the media and our own labels. But guess what? They are only thoughts. Just because you think these thoughts, it doesn’t make them true. —【5】—.

A. You have the power to change your future.
