We all agree that we should recycle less — at home, in the office or when out and about. But for material to be actually recycled, they first need to find their way to the right waste stream so that they can be then collected and taken to the right place for recycling. This is what the process of sorting allows us to do it.
For effective recycling we need effectively sorting — and this needs to happen first, in our own home and second, in dedicated sorting plants to that waste collected from our doorstep and collecting points is taken. When you put a plastic bottle in the right recycling bag and bin, you are helped sort recyclable waste so that the right material can be fed into the right recycling process. Unless sorting does not happen, a lot of recyclable materials can end up in landfills or be burned, with valuable resources lose from our economy. Sorting at home is first step towards recycling.
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
The Program for International Student Assessment (PISA), first conducted in 2000, 1.(be) an international assessment hosted by the Organization for Economic Cooperation and Development (OECD) which measures 15-year-old students’ reading, mathematics, and science literacy every three years. The latest 2018 PISA found 2. 15-year-olds in Beijing, Shanghai and the provinces of Jiangsu and Zhejiang (B-S-J-Z) ranked No.1 in all three core subjects.
3. were followed by students from Singapore and China’s two special administrative regions — Macao and Hong Kong. The top OECD countries were Estonia, Canada, Finland and Ireland.
The OECD's PISA 2018 4. (test) around 600,000 15-year-old students in 79 countries and regions on reading, science, and mathematics. The main focus was on reading, with most students doing the test on computers.
In B-S-J-Z, socio-economically 5.(advantage) students outperformed disadvantaged students in reading 6. 82 score points in PISA 2018. This is not 7. (significant) different from the average difference between the two groups (89 score points) across OECD countries.
School principals in B-S-J-Z reported more staff 8.(short) and less material deficiency than the OECD average.
In almost every education system, girls expressed greater fear of failure than boys, and this gender gap was considerably 9.(wide)amongst top-performing students.
In B-S-J-Z, students spent 31.8 hours in the classroom on average, 10. (rank) fourth among all 79 countries and regions. The learning efficiency of students in B-S-J-Z ranked 44th, 46th and 54th for reading, math and science, respectively, and the students' satisfaction about learning only ranked 61st.
The term “the imaginary audience” was invented by American child psychologist David Elkind in 1967. It is defined as a psychological state in an adolescent, _______ by the belief that people around are eagerly watching or listening to him or her. This is because _______ are aware of the physical changes _______ in their bodies. And they are _______ concerned with how everyone is _______ these changes.
The _______ of the imaginary audience are common. Teens would repeatedly change their clothes to look _______ to others. Or they would follow different ongoing _______ that may help them fit into society. If wearing checkered shirts and jeans is the current fashion, teens would_______ like that just to give a good ____________ on their imaginary audiences. Teens also worry about the ____________ mistakes they make in social settings. A blackhead could make an adolescent girl ____________ all day as she feels that she is being watched and ____________. ____________, in reality, there are only a small percentage of people who are actually interested in how somebody else ____________.
Though “the imaginary audience” is considered to be a ____________, it is a natural process in which an adolescent tries to develop a better understanding of his or her ____________ with the world. As an individual's perception (理解) of the world ____________, he or she will gain more ____________ viewpoints on his or her roles among people, rather than imaginary ones. Thus, the effects of imaginary audiences will gradually ____________.

A new device is helping those who are blind to see. It does this in a new way by helping them experience the world around them. The technology is called Orion, manufactured by a company called Second Sight. 1. From being able to see absolutely nothing to suddenly seeing little flickers of light, the blind can move around alone, telling where a doorway is and where the sidewalk begins or ends.
2. One is a small device placed in the brain. There is also a video camera on sunglasses and a processing device carried in a person’s clothes. When the user points the camera, a signal goes to the processor and then back to the glasses. The glasses then communicate wirelessly with the device in the brain. The information causes a pattern to develop in the part of the brain called the visual cortex (皮质). 3. And it all happens in seconds.
Jason Esterhuizen is one of just two people in the U.S. testing this technology. He lost his eyesight after a car accident. He never thought he would be able to see light or movement again. But with the movement of a switch, his world suddenly grows brighter. 4.For example, it is easier and safer for him to cross the road because he can look down and just follow the white line that's painted on the road.
Researchers believe that one day this technology could benefit people who have lost their vision because of illnesses like glaucoma (青光眼) or diabetes. 5.
A.It may also help those with poor vision or who were born blind.
B.The new technology generally uses several parts.
C.He is amazed to have the functional vision again.
D.It is meant to help these people regain some independence.
E.He can do everyday activities that he once could not.
F.In this way, users detect movements and shapes of light.
G.It basically performs the functions of what the eye normally does.
From talking robots to driverless vehicles, technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet-we still have no cure for the common cold.
Why can't we stop the common cold? According to Peter Barlow, a scientist at Edinburgh Napier University, the main challenge lies in the many different types of cold viruses that belong to the rhinoviruses(鼻病毒). There are at least 160 types.They mutate(突变) so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn't likely to work on every type of cold.
However, researchers from Stanford University and the University of California, San Francisco, have found a possible answer. They discovered a protein(蛋白质) that the viruses need. All the viruses were unable to replicate(复制) inside cells without a gene that produces a specific protein called SETD3.
To identify the gene which produces the specific protein, researchers used a gene-editing technique to test all genes in the human genome (基因组). Namely, they randomly disabled a single gene in each of the cells, so that the cells lacked one or another of every gene in our genome. These genetically modified cells were then exposed to the rhinoviruses, which cause the common cold. The team then looked at which gene was missing in cells that continued to grow. As it turned out, the one that stood out was SETD3, which makes a protein of the same name.
Carette said the plan is to find a drug which can temporarily disable the protein, instead of producing genetically modified humans. “We have identified a fantastic target that all rhinoviruses require and depend on. Take that away and the virus really has no chance,” said Carette.
1.Which does Peter Barlow think is a problem for fighting the common cold?
A.The poor immunity of patients. B.The large variety of viruses.
C.The lack of enough cures. D.The side effects of drugs.
2.What do we know about the gene-editing study in Paragraph 4?
A.All genetically modified cells survived B.Some genes in our genome were ignored
C.It located the gene responsible for SETD3 D.It exposed the harm of the rhinoviruses.
3.How should we stay away from the common cold according to Carette?
A.Apply gene-editing to human genes B.Avoid contacts with colds patients
C.Prevent cold viruses from mutating D.Develop a drug to switch off SETD3
4.Which of the following is the best title for the text?
A.Potential defense found for cold viruses B.Secrets behind the human genes
C.Real causes of the common cold D.Puzzles over rhinoviruses solved
