When you're curious_about something, and want to know more about it, you can use the way of asking questions.Asking questions is the first step to make discoveries and find interesting answers.The steps below can guide you during the research (研究)．
Step 1 On a notecard or piece of paper, write down the subject that you are interested in.Just get the main idea down.For example, you might write: Discover more about dinosaurs.
Step 2 Next, stop and think for a moment about what you already know about your subject.List what you already know like the sentences below：
(1)Dinosaurs lived long before human beings appeared.
(2)Dinosaurs lived on the earth for more than 150 million years.
(3)Some dinosaurs fed on (吃) plants, some on meat.
Step 3 What can you do with what you want to learn? By asking questions.On your paper，start writing down questions about the dinosaurs as you think of them：
(1)What's the best weather for dinosaurs to live in?
(2)How many kinds of dinosaurs are there?
(3)Have dinosaurs really disappeared?
Step 4 Armed with your list of questions, you can now go to the nearest library or computer to begin your research.As you learn more about your subject, you'll probably discover some new questions.For example，you might discover that dinosaurs disappeared about 65 million years ago.Why? What happened？Asking new questions can help you research your subject more widely.

答案：B
B
Imagine a baby having difficulty breathing when he was born.What this tiny baby needs badly is a respirator, a device that will help him breathe to live on.
The first highly reliable，medical respirator in the world was invented by Forrest Bird.Often called the “Babybird” respirator, this wonderful device reduced baby deaths across the world.
Forrest Bird was born in Massachusetts, USA.His father was a World War Ⅰ pilot and encouraged his son to fly at a very early age.By 14, Bird could fly an airplane by himself.
He joined the Air Force as a technical air training officer during World War Ⅱ.This gave him a chance to fly a wide variety of airplanes.Some of these were designed to fly very high, at altitudes where a pilot would find it difficult to breathe.
This problem aroused Bird's imagination.He wanted to create devices，which would aid breathing in such altitudes.So deep was he absorbed in it that he quit his job, and went back to attend medical school.Studying medicine gave him an insight into the complete workings of the human system.He understood the mechanics of human breathing.
And the first “respirator” was made.Bird had developed the first device, which could help people breathe.This invention of Bird, however, was to be used, not by pilots，but by seriously ill patients with breathing difficulty.So earnest was he that he traveled in his own airplane to medical schools and asked doctors for their most ill patients.If these patients were not aided with the respirator，they would die.He tested the device on such patients.This test itself saved many lives.
The respirator became a great success and was known as “the bird”．It was a common statement among doctors to say, “If all else has failed, get the bird．” “The bird” was a little green box which became familiar to hospital patients throughout the world after it was introduced in 1958.
6．It can be inferred from the passage that Bird became a pilot because________.
A．it was his dream
B．his father encouraged him to
C．he liked flying planes
D．he attended a flying school[来源:21世纪教育网]

A．many babies had difficulty breathing
B．patients in the hospital couldn't breathe easily
C．a pilot had difficulty breathing at high altitudes
D．pilots couldn't fly their airplanes to higher altitudes[来源:21世纪教育网]
解析：细节理解题。根据第四段最后一句话“Some of these were designed to fly very high, at altitudes where a pilot would find it difficult to breathe.”和第五段第一、二句话“This problem aroused Bird's imagination.He wanted to create devices，which would aid breathing in such altitudes.”可知，飞行员在高处飞行的时候常常感到呼吸困难，这成了伯德发明的动力，他想制造出一种能让飞行员在这样的高度不感到呼吸困难的仪器 。
答案：C
8．The underlined word “quit” in the fifth paragraph probably means________.
A．stopped B．continued21世纪教育网
C．kept D．found

A．doctors were fond of the bird
B．doctors raised a bird to cure patients
C．doctors couldn't cure patients without the respirator

A．In the 1940s. B．In the 1950s.
C．In the 1960s. D．Not told.

[1] Parenting a toddler (初学走路的小孩) is quite difficult for most parents. At this age, when children are learning so fast and changing every day, how can we help them to grow up well? Here are a few of the most common mistakes to avoid (避免)．
[2] Offering too much help
It's easy for parents to jump in and help your toddlers finish puzzles or fasten their shoes, but toddlers need to learn ________________________. So let your children try to do things on their own, but offer them plenty of encouragement.
[3] Feeding them nothing but “junk food”
Children's menus in restaurants are often full of nothing but junk food — hot-dogs, hamburgers, deep-fried chicken and other fast food. Grocery stores are also full of unhealthy food marketed towards children. There is no reason why toddlers cannot eat most of what adults do. Put something of everything you are eating on your child's plate, but don't pressure him to eat it all. Your child might hate it if you try to force him to eat something.
[4] Allowing too much screen time
Spending too much time watching TV could give your child learning problems later in life. Children under two shouldn't watch any TV at all. You should find more creative things to do with your child, like reading, drawing, or chatting.

式为“...not as/so＋原级＋as ...”

— Why? It's ______ than the films I have ever seen.
A．far more interesting B．much less interesting
C．no more interesting D．any less interesting解析：考查形容词的比较级。句意：“我得说，这部电影没趣。”“ 为什么呀？(我觉得)比我曾看过的电影有趣得多了。” not a bit“ 一点儿都不”。根据句中的 than可知，此处应用形容词的比较级，而interesting 为多音节形容词，其比较级是在前面加more，如果表示程度，则在 more前加 far。
答案：A4．“否定词＋比较级” 结构表示最高级含义

他过了最忧虑的一天。
