【題目】 Read the passage and fill in the blanks with proper words.

Have you ever noticed the black and white bars on a book? Do you know what they are used for?

They are barcodes(條形碼) used in most products. If you go to a supermarket, you can see almost every product with a barcode on it. Barcodes contain i1about the product, such as name and production date. It’s an easy and convenient way to know about the products. Just scan(掃描) the bars with a barcode reader and everything is c2.

The first use of a barcode in a supermarket checkout system was on a pack of American Wrigley Company chewing gum(口香糖) in 1974. Beyond supermarkets, barcodes are needed e3: for renting cars, for luggage checks on a plane, for parcels you send; life would be rather difficult without barcodes. Most of our things would get lost in the post.

Barcodes c4 as well. Barcodes in the past were 1-D, but now there are 2-D barcodes, such as QR code. Since 2009, QR has been used on Chinese train tickets. People can e5 stadiums, cinemas and theaters by holding certain types of barcodes.

If you find these barcode things b6, a barcode building might be more up your street. In St Petersburg, Russia, there is a building designed like a barcode. It looks strange, but it’s a7 a shopping mall. There are games too. Barcode Monsters is a mobile phone game. You have to scan barcodes and find the monsters!

【解析】

本文是一篇說明文,主要介紹了條形碼的含義和發(fā)展歷程。從最初用在產(chǎn)品上幫助消費(fèi)者識(shí)別產(chǎn)品到后來發(fā)展為二維碼被中國人印在火車票上,現(xiàn)在還有仿條形碼的建筑物和游戲。

1句意:條形碼包含有關(guān)產(chǎn)品的信息,例如名稱和生產(chǎn)日期。

根據(jù)題干中的舉例“such as name and production date”和首字母提示“i”可知條形碼包含了有關(guān)產(chǎn)品的信息,故答案為information。

2句意:只需使用條形碼閱讀器掃描條碼,一切就很清楚了。

根據(jù)首字母“c”和“barcode reader 條形碼閱讀器”可知掃碼后產(chǎn)品信息非常的“清楚”,故答案為clear。

3句意:除超級市場外,到處都需要條形碼:用于租車,用于飛機(jī)上的行李托運(yùn),用于你寄送的包裹。

根據(jù)冒號后舉例“for renting cars, for luggage checks on a plane, for parcels you send”和首字母“e”提示可知條形碼存在于我們生活的“方方面面”,故答案為everywhere

4句意:條形碼也發(fā)生了變化。

根據(jù)后文“Barcodes in the past were 1-D, but now there are 2-D barcodes, such as QR code.”和首字母“c”提示可知條形碼從過去的一維變化出了現(xiàn)在的二維,如二維碼,故答案為change。

5句意:人們可以拿著特定類型的條形碼進(jìn)入體育場,電影院和劇院。

根據(jù)題干中出現(xiàn)的大量地點(diǎn)和首字母“e”的提示可知很多地方已經(jīng)是掃碼“進(jìn)入”了,故答案為enter。

6句意:如果您發(fā)現(xiàn)這些條形碼很無聊,那么條形碼建筑物可能就在您的街道上。

根據(jù)后文“barcode building 條形碼建筑物”、“Barcode Monsters 條碼怪獸”和首字母“b”提示可知人們發(fā)明了很多條形碼的其他用途來把無聊的條碼變的有趣,故答案為boring

7句意:它看起來很奇怪,但實(shí)際上是一個(gè)購物中心。

根據(jù)前文“barcode building 條形碼建筑物”和后文中的“shopping mall 購物中心”以及首字母“a”提示可知條形碼建筑物“實(shí)際上”就是一個(gè)購物中心,故答案為actually

Jupiter(土星) is the fifth planet from the sun and it is the largest one in the solar system. It is about 11 times bigger than the earth. Jupiter's strangest thing is its huge red spot. Pictures taken from space tell us that the red spot is probably a hurricane(颶風(fēng)). It is so big that the earth would fit right in the middle of it.

【題目】根據(jù)短文內(nèi)容的理解,選擇正確答案。 A school bus is one that is used to take children to and from school.
In the USA, about 450,000 school buses take more than 25 million children to and from school. The yellow school bus is a US icon (象征). Yellow became the color of school buses in the USA in 1939. Dr. Frank got the good idea. He said it was easy for people to see yellow buses and the black letters on them in early morning or late afternoon. That would make children safer.
There are not many school buses in Britain, and they are not yellow. They have trackers (追蹤器) on them, so kids are being tracked while they travel to and from school by bus. The trackers let parents know where the school bus is and whether their kids are on the bus.
Kindergarten (幼兒園) is a difficult time for some kids. It's the first time for them to go away from their parents. To make kids love their school, Japanese kindergartens and schools have colorful buses. The buses can easily make children want to take them--and then, go to school. Even some parents want to take them, too!
School buses are becoming more and more popular in China now. It saves a lot of time for students to take a school bus.
(1)According to Dr. Frank, school buses are safer for the students.
A.yellow
B.black
C.white
D.red
(2)According to the passage, in which country do the school buses have trackers?
A.France
B.Britain
C.German
D.Japan
(3)Children in Japan may easilyby taking the school bus.

【題目】Answer the questions.

Big floods in Beijing and Tianjin last summer took the lives if nearly one hundred people.Most of them drowned,but a few people were electrocuted by power lines falling into the water. Cites like Beijing do not often experience big floods -it was called a once-in-a-hundred-year event-and the people in the cities were unprepared when the disaster came.

Climate change seems to be making “unlikely”weather events such as floods more common and it only makes sense to prepare ourselves for when disaster strikes. In the case of floods, just learning to swim won’t help you much. The water flows so fast and is so filled with floating debris(碎片)that even Olympic gold medal winner Ye Shiwen would have troubles keeping her head above water.

The first thing you should do is to take the warnings of heavy rains or typhoons seriously. You should stay home, listen to the news reports and wait for the waters to subside(回落). If you live at ground level, move to a higher level. You should also call people to tell them you are safe so that they don’t risk their lives searching for you. It’s also a good idea to have a “grab”bag (an emergency bag)”ready at home filled with power bars(能量棒),a flashlight and bottles of water. In a flood , the electricity is often knocked out and drinking water-becomes contaminated(被污染的).

The most important thing is to stay calm and be patient. It’s the best way of keeping your head above water.

1The people in Beijing and Tianjin got prepared when big floods came, didn’t they?

_______________________________________________________________.

2Why would Ye Shiwen even have trouble saving herself if a flood comes?

______________________________________________________________.

3Is it important to take the warnings of heavy rains or typhoons seriously or not?

_____________________________________________________________.

4How can we stop people risking their lives searching for us in a flood?

We can stop people by ____________________________________________.

5What should we put into our “grab bag”?

______________________________________________________________.

6What will you do if a flood comes? Tell me your reason(s), please.

____________________________________________________________.

【題目】任務(wù)型閱讀,閱讀下列短文,根據(jù)短中的信息完成文后表格。(每空一詞)
Have you ever been so worried about something that you have a headache or even can't sleep at night? Then you cannot pay enough attention during a test or in your study. If so, then you know that is stress. You are worried too much about something. The bad feeling in your mind can make you angry, sad, or scared, and can even give you a stomachache or a headache.
However, some kind of stress is good. You might feel excited when you are called to give a speech at school. You feel nervous but excited. This kind of stress can help you to get things well done. And you may do a better job in your test if the stress pushes you to prepare more beforehand(提前).
On the other hand, bad stress can last long if you are unable to come over your problems. You may not feel well, if your parents are having a quarrel, if a family member is badly ill, if you're doing poorly at school, or if anything else makes you unhappy. That kind of stress isn't going to help you. And it can actually let you do worse in your daily life.
The best way to fight the stress is to have a balanced life. Make sure you get enough sleep and eat properly. Have some regular exercise. You should take some time for fun. Get advice from your parents, teachers and friends. Soon after that, you'll probably get away with your stress.
