Have you ever wondered who made this marvel(奇迹)?In 1406, when the Ming Emperor Yongle decided to move the country's capital from Nanjing to Beijing, he started to build a palace at the heart of Beijing. His vision(愿景)was big. It took a million workers 14 years to finish it.Materials were sent from all over China to Beijing. Nanmu, the rarest of all Chinese woods, was used to make huge wooden pillars(柱子). It can only be found deep in forests over 1,800 km away from Beijing. Workers had to float(漂浮)the wood on rivers all the way north to Beijing.Stones were also carried to the palace. The heaviest stone in the Forbidden City weighs 250 tons. It was found 80 km west of Beijing. It was so heavy that people could only move it during winter. They poured water onto the road to create ice. Then thousands of workers pulled the stone on the ice to the palace.The project even changed the local landscape(地貌). While building a moat(护城河)around the palace, workers dug up soil and piled it on a hill north of the Forbidden City. That's where Jingshan came from.(1)What can't we learn from Paragraph 3?A.How long it took to build the Forbidden City.B.Who decided to build the Forbidden City.C.Where the Forbidden City was built.D.How the Forbidden City got its name.(2)Paragraph 4 mainly shows that ________.A.North China had few treesB.some building materials came from far awayC.hinese people were hard-working in the pastD.river transportation started in ancient times(3)Workers transported stones in winter because ________.A.the icy rivers helped them transport stonesB.winter is the best season to make carvingsC.stones are lighter when they're frozenD.they had to use ice to move the stones(4)What do we know about Jingshan?A.It was built with soil from the palace.B.It was part of the Forbidden City.C.It was moved in order to build a moat.D.It was there before the Forbidden City.(5)The process of building the Forbidden City was ________.A.simple B.difficult C.smooth D.dangerousDo you know what Alzheimer's disease(阿尔茨海默病)is? People with this disease are very forgetful. When US high school student Sarah Earp saw her family members suffer from this disease, she decided to do something.Earp started a fundraising project(筹款项目)this year and has raised more than 3,000(21,081 yuan)so far.Earp still remembers her family members always asking her the same questions over and over again. "It makes it a lot harder," she said. "I would really like to help more people."She made videos about the disease and showed them to students. In one video, she sits beside her aunt, who has Alzheimer's. Her aunt says "that's terrible" after hearing some facts about Alzheimer's. But the next moment, she has already forgotten what Earp was talking about.Earp also put up posters(海报)around her school.

Why do different kinds of fruit have so many colors?According to Lu Wei from the Chinese Academy of Sciences, fruit colors actually come from their different pigments(色素), such as red or yellow carotenoid(类胡萝卜素)and blue or purple anthocyanin(花青素). These pigments appear in different amounts, depending on the fruit's environment. This causes the fruit to turn a certain color.To find out how environment influences fruit colors, Chinese scientists studied more than 280 different fruit colors, including white, red, blue, purple and black.They found that red fruit tends to grow in cooler places. And instead of just growing in one place, you can find them growing in many places around the world. Blue and purple fruit mostly grows in warm places. These fruit tend to grow a lot in just one specific area. The scientists also found that the closer the fruit is to the equator(赤道), the darker its color will be.Animals have also had an influence on the evolution(进化)of fruit colors. Animals eat fruit and drop the seeds in other places later. This helps the fruit spread and grow in different places. Therefore, in order to attract animals, some fruit develop colors that are easy for animals to see.However, animals see colors in a different way. Fruit needs to develop colors that are suited to animals' visual abilities. For example, birds can see red more easily than humans can. Therefore, there tends to be more red fruit in areas where birds live. The lemurs(狐猴)of Madagascar are red-green color-blind. Many yellow fruit can be found in their habitats(栖息地), as they can easily see this color.(1)You are more likely to find blue and purple fruit in ________.A.cooler places B.warmer places C.higher places D.lower places(2)Which of the following is TRUE?A.Dark fruit tend to grow close to the equator.B.Green fruit tends to grow in cool places.C.Humans can see red more easily than birds.D.Birds are color-blind and can see no colors.(3)Some fruits develop certain colors to ________.A.scare animals awayB.get more sunlightC.attract animals to eat themD.protect themselves(4)Which of the following factors have influenced the evolution of fruit colors? a. environment b. pigment c. animals d. humans' visual abilitiesA.abc B.bed C.ac D.bd(5)What do the fifth and sixth paragraph mainly talk about?A.How animals influenced the evolution of fruit colors.B.Why animals loved fruits with bright colors.C.Where animals usual got fruits.D.How and where fruit colors attracted animals.

ㅤIn the race to document the species on Earth before they go extinct，researchers and citizen scientists have collected billions of records.Today，most records of biodiversity are often in the form of photos，videos，and other digital records.Though they are useful for detecting shifts in the number and variety of species in an area，a new Stanford study has found that this type of record is not perfect.ㅤ"With the rise of technology it is easy for people to make observations of different species with the aid of a mobile application，"said Barnabas Daru，who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences."These observations now outnumber the primary data that comes from physical specimens（标本），and since we are increasingly using observational data to investigate how species are responding to global change，I wanted to know：Are they usable？"ㅤUsing a global dataset of 1.9 billion records of plants，insects，birds，and animals，Daru and his team tested how well these data represent actual global biodiversity patterns.ㅤ"We were particularly interested in exploring the aspects of sampling that tend to bias（使有偏差） data，like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it，"said Daru.ㅤTheir study revealed that the large number of observation-only records did not lead to better global coverage.Moreover，these data are biased and favor certain regions，time periods，and species.This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby.These data are also biased toward certain species with attractive or eye-catching features.ㅤWhat can we do with the imperfect databasets of biodiversity？ㅤ"Quite a lot，"Daru explained."Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places--and even species--that are not well-sampled.To improve the quality of observational data，biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image."（1）What do we know about the records of species collected now？ ____ A.They are becoming outdated.B.They are mostly in electronic form.C.They are limited in number.D.They are used for public exhibition.（2）What does Daru's study focus on？ ____ A.Threatened species.B.Physical specimens.C.Observational data.D.Mobile applications.（3）What has led to the biases according to the study？ ____ A.Mistakes in data analysis.B.Poor quality of uploaded pictures.C.Improper way of sampling.D.Unreliable data collection devices.（4）What is Daru's suggestion for biodiversity apps？ ____ A.Review data from certain areas.B.Hire experts to check the records.C.onfirm the identity of the users.D.Give guidance to citizen scientists.
