The engineers explained how their new material works. They said when it is put on top of something, two things happen. It cools the object underneath by 8(reflect) the sun's rays back into space. At the same time, the material removes the object's own heat and sends that into the air. An engineer said: "We're excited about the opportunity to explore potential uses in different scientific 9(field)." Another researcher said: "Just 10 to 20 square meters of this material on the rooftop could 10(nice) cool down a house in summer."

【答案】

1has created

2which

3nor/neither

4the

5to run

6found

7thicker

8reflecting

9fields

10nicely

【解析】本文是一篇说明文,主要向我们介绍了一种比锡箔纸稍厚的可以保持建筑物凉爽的新材料。

1考查时态。“A team of engineers ___1___(create) a super-thin material that could help keep buildings cool.”句意:一个团队的工程师创造了一个超薄的材料,可以使建筑物保持凉爽。讲的是过去发生的事对现在产生的影响,故应该用现在完成时,故填has created。

2考查非限制性定语从句。“The team developed the revolutionary new material, ___2___ is very thin and can cool objects even under direct sunlight.”句意:研究小组开发了革命性的新材料,这种材料非常薄,即使在阳光直射下也能冷却物体。考查非限定性定语从句,先行词是the revolutionary new material,故填which。

3考查固定句型。句意:这种材料不需要能量来工作,也不需要水来帮助保持凉爽。此题考查固定搭配。not ...nor ...或not...neither...意为“不……也不……”,符合语境,故填nor/neither。

4考查冠词。句意:工程师们说这种新材料可以为空调提供答案。这种材料就是文中前面所提到的,是特指,故填the。

5考查非谓语动词。句意:这是昂贵的运行。在“be + 性质形容词 + to do”结构中,通常使用不定式的主动形式表示被动意义。故填to run。

6句意:这种材料与自然界中发现的任何东西都不一样。这种发现是指过去发现的一切,所以应该用过去时,故填found。

7句意:这比铝箔稍厚(锡箔纸)我们用来煮饭。由than可知,此题考查形容词的比较级,故填thicker。

8句意:它通过反射太阳光线回到太空使物体冷却。by doing sth意为“通过做某事”,故填reflecting。

9句意:我们很高兴有机会在不同的科学领域探索潜在的用途。different scientific fields“不同的科学领域”,所以应该用名词的复数形式,故填fields。

10句意:只有10到20平方米的屋顶上的这种材料可以在夏天很好地冷却一个房子。修饰动词cool(冷却)应该用副词形式,故填nicely。

Any type of regular, physical activity can improve your fitness and your health.
Exercise should be a regular part of your day, like brushing your teeth, eating and sleeping. It can be in gym class, joining a sports team, or working out on your own. Keep the following tips in mind:
A good attitude is important. Find an activity that you think is fun. You are more likely to stick with it if you choose something you like. A lot of people find it's more fun to exercise with someone else, so see if you can find a friend or family member to be active with you.
Take it one step at a time. For example, walk or ride your bike to school. Get on or off the bus several blocks away and walk the rest of the way. Use the stairs instead of taking the elevator.
Get your heart pumping. Whatever you choose, make sure it includes aerobic (有氧的) activity that makes you breathe harder and increases your heart rate. This is the best type of exercise because it increases your fitness level and makes your heart work better. Examples of aerobic activities are basketball, running, or swimming.
Don't forget to warm up with some easy exercises or stretching (拉伸) before you do any physical activity. It is also important to stretch out after you exercise to cool down your muscles.

【题目】There is no doubt that going without sleep for too long makes us feel terrible, and that getting a good night’s sleep can make us feel ready to take on the world. 1 Here are some top tips on getting the most out of the night.

2 You’d better avoid eating any food three hours before bed, as it will lower your blood sugar during sleep and help minimize damage from too much sugar floating around.

Keep your bedroom dark. To get a good night’s sleep, you need a bedroom that is pleasant, inviting and welcoming. 3 This is because the all important sleep-inducing (催眠) hormone melatonin is extremely sensitive to light, and may not be produced optimally (最佳的) unless it’s completely dark.

4 The foundation of good sleep is a comfortable bed. The right mattress (床垫) can make the difference between a refreshing night’s sleep and poor quality sleep resulting in tiredness and fatigue.

Get into a relaxed state. 5 Both of them will help to take the mind off the daytime pressures.

Since the start of the 21st century, studies have linked a lack of sleep to many diseases, such as diabetes and obesity. Taking action now will lead to long-term benefits for you.

A. Take a bath or listen to soft music.

B. Never eat too much before bedtime.

C. Above all, it should be dark.

D. Healthy people value a good night’s sleep.

E. However, not all of us know the best way of getting it.

F. Experts suggest putting away your mobile phone.

G. Have a suitable bed, especially a suitable mattress.

Hannah Levine decided she wanted to give hugs to all of the children and families in need at local hospitals.
Because she couldn't give them one by one, Levine, then a sixth-grader, decided she would use her talents(才能) to do the next best thing. She began to knit(编织) hats, scarves, and blankets for families staying at the Ronald McDonald House at Stanford. Her creations also went to Bundle of Joy, a program that provides newborn baby items for families in need, and to Knitting Pals by the Bay, a local organization that provides hand-knitted caps to cancer patients.
“I love to knit, and I thought it would be a great idea to make all these handmade items for kids and adults who need them. It would be like a hug for them,” Levine explained.
Levine started the project about a year ago. “I think it's just really fun to do, and it keeps me busy,” said Levine, now 13.
Once she got started, Levine realized that her project could be much bigger than the goods she was able to produce with just her own hands. So she sent emails to her school and communities(社区), asking for knitted donations(捐赠物) to the project she named “Hannah's Warm Hugs”. She also posted advertisements at Starbucks and other locations in her area. The warm goods began to gush in.
“It was amazing; more strangers than people she knew started dropping donations at our door,” said Levine's mother, Laura Levine. “We ended up with this huge box of items she was donating.”
The knitted items numbered in the hundreds. Levine made her first round of donations around Hanukkah (an eight-day Jewish holiday in November or December) and later received thank-you letters from the organizations. Levine is still knitting, and she said the project will continue.
“It has turned into a bigger thing than she had thought,” her mom said. “It made her feel pretty good; it made us feel pretty good.”
(1)Hannah Levine knitted hats and scarves ________.
A.for children and families in difficulty
B.to raise money for cancer patients
C.to earn some pocket money
D.for the homeless in her neighborhood
(2)The underlined part “gush in” in paragraph 5 can best be replaced by “________”.
A.take off

D.break in
(3)What would be Laura Levine's attitude toward Hannah Levine's project?
A.Optimistic but worried.
B.Proud and supportive.
C.Concerned but doubtful.
D.Unfavorable and uncaring.
(4)What would be the best title for the text?
A.Be ready to lend a helping hand
B.Start a project to show your support
C.Teen turns knitting hobby into heartwarming project
D.13-year-old girl becomes US best knitter

I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. There was a time when I thought I would never have that sort of career.
I wasn't an excellent student because I didn't do much schoolwork. In my final term I started thinking what I might do and found I didn't have much to offer. I just accepted that I wasn't the type to have a career.
I then found myself a job — looking after two little girls. It wasn't too bad at first. But the problems began when I agreed to live in so that I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she'd give me time off the next. But unfortunately, it didn't often work out. I was getting extremely tired and fed up, because I had too many late nights and early mornings with the children.
One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification(资格证书)if I wanted to work with children. I didn't think I would be accepted because I didn't take many exams in school. She persuaded me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.
Now I've got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that you could have a career, even if you aren't top of the class at school.
