①Chemistry is everywhere in our daily life.Sometimes it's easy to see.At other times，it can be very hard to see the everyday chemistry at work，but nearly everything you touch has some chemicals（化学物质） in it.
②Chemistry helps to make products for use.Something as simple as toothpaste has at least three chemicals that keep your teeth clean.Other things in your daily life are created by chemistry，such as hair products and soap.Without chemistry，we would never have known that we need soap to get the oil out of clothes.
③Chemistry also helps us understand the world around us.Thanks to chemistry，we know bleach （漂白剂） can't be mixed with vinegar （醋），because the mixture can produce harmful gas.
④Chemistry plays a big role in food preparation.Cooking food causes it to go through a chemical change.That is why cooked food often tastes different from uncooked food.Too much or too little of any chemical material makes a difference to the result of baking （烘焙）.For example，the cake can be too soft or too hard.
⑤Chemistry isn't something that just lives in a laboratory，it's something that you meet hundreds of times in life.Knowing how chemistry works will give you a greater understanding of the life.

The Chang’e-3, named after a Chinese goddess, is China’s first spacecraft(航天器)to make a soft landing on the moon. It includes a lander and a moon rover(月球车) called Yutu. The Chang’e-3 spacecraft is the second phase(阶段) China’s lunar programme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang’e-1 and Chang’e-2 spacecraft in 2007 and 2010. The launch of Chang’e-3 was successful.
The Chang’e-3 is one of the most difficult tasks in China’s space programme, the news says. The news adds that exploring the universe(宇宙) and seeking peaceful use of space are dreams of Chinese for thousands of years.
With a lander and the moon rover Yutu, Chang’e-3 soft-landed(软着陆) on the moon at 9:11 p.m. Saturday. Yutu later separated(分离) from the lander and ran to the moon surface earlier Sunday.
China has chosen the name Yutu for its first moon rover, after a worldwide online vote(投票) attracted people to come up with names.
In Chinese folk tale, Yutu is the white pet rabbit of Chang’e, the moon goddess. Chang’e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since.Which is the first spacecraft landed softly on the moon in China?

North American black bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals.
In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases(疾病), remove a tooth and take it to the lab to find out its age. Fromthese studies, researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies they produce.
But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapesto keep the bears busy, researchers can touch them to check their hearts, look at theirteeth, and do other jobs.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives.
In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But theresearch methods and the kinds of information that researchers, are able to collect are quite different.In the first paragraph, we can learn that North American black bears are _______.
| A．shy and fearful animals | B．not found today |
| C．well known to scientists | D．not afraid of people |
The word "remove" in the second paragraph probably means _____ in Chinese.

As Keira climbed into bed, she thought about tomorrow’s field trip. Her class was going to a presentation by a West African traditional storyteller. Keira was excited because she was of West African descent. Her great-grandmother had come to the United States from Senegal, a country in West Africa. Until now, Keira hadn’t thought much about her roots(根源).
Early the next morning, Keira looked everywhere for something to show her West African roots. She dug through every drawer, but she couldn’t find anything that really stood out. Finally, she put on a white shirt and jeans. Although she wore ordinary clothes, she hoped that her interest in her West African roots would not go unnoticed.
At the community center, Keira was lucky enough to get a front-row seat. The first speaker talked about African writers and how they often use traditional stories with traditional characters, such as the Tortoise and the Spider. The speaker mentioned writers her mother and grandmother liked! Also, Tortoise was a favorite character in Keira’s bedtime stories. Finally, the speaker mentioned Doudou N’Diaye Rose. He was Keira’s favorite drummer. He was from Senegal. She began to realise just how much her West African roots influenced her American life.
Finally, the storyteller came up. He told a story that explained how the chameleon, a small lizard(蜥蜴), changed its colors. Then he introduced the Spider and Tortoise. It was known that they appeared to be generous but in fact they wanted to keep everything for themselves. Some of the stories made these characters seem poor as they fought for every last piece. However, they were simply naughty(调皮的). They certainly did learn their lessons!
Keira couldn’t keep her mind from thinking about all the different stories her mother had told. Her memory was pouring out again! She knew about everything the storyteller said.
After the presentation, the class talked to the storyteller. Keira told about how her great-grandmother had moved to the United States from Senegal. Her great-grandmother left her village because of a famine, a time of hunger. She had explained to Keira’s grandmother that the villagers spent days begging for food. Her great-grandmother finally came to the United States. Keira told the storyteller about those of her bedtime stories.
When Keira was finished, the storyteller pointed out that she had just done his job. She had described her family and the stories they told. Keira could hardly wait to tell her mother and grandmother the news!
